@UglyTruckExperience 01 silverado in an 83 el camino. Engine,trans,harness and ecu from truck. Known rebuilt and good trans. I had it rebuilt and drove it a year before harvesting it.
In your case you will need to take the two pink wires, connector 2, pin f2 and put it in E8 on connector 2 if you are not using the rear O2 sensors. The wiring for that transmission originally came from the interior fuse panel which is not there. The older wiring diagrams are very misleading about the fuse boxes. If you are using the rear O2 will just need to run F2 to a key on engine running source. Good luck. Hope this helps. Jerry
I just saw your page last night. For the last year I have been driving my LS swapped 1988 Nissan pickup in 3rd gear, thinking I had either bad shift solenoids or a failing transmission. So, I have been manualyl shifting to get going. I just bought another used 4L60 this past Statuary. So, before I removed the old transmission, today I did what you suggested. I ran 12 volts to pin C9 in connector C1 and like magic, it starts in low and shifts properly. No one else ever suggested this but you. Thanks a million friend. Thanks very much. Hope you have a great day!!!!!!!
This is so awesome!! So glad you found us! Do you have any pics of your truck? We have a customer who wants to swap an 86 Nissan, and I'd love to check out your build! Thanks for watching! -emily
I sure do have pics. Just tell me where to send them. Awesome power increase over the anemic 4 cylinder and automatic transmission that was in there before. I will send them tomorrow, Wednesday. I live in Lawrenceville Georgia.
@@thomasreid8504 I bet that truck is a blast to drive! If you have Instagram, we're @uglytruckexperience. Or our Facebook page is Ugly Truck Experience. Can't wait to check it out! 😁
I’ve been watching your videos in search for the answer to my issues. I have a 1996 Fleetwood with the LT1 and a 4L60E swapped over to an 0411 PCM. It runs great but starts off in 1st and will only shift manually from there. It does have 1st 2nd and 3rd. It does have a VSS reading and when unplugging the transmission it seems to throw every code in the book so I believe the transmission is getting proper power. I’m just stumped because it shifted perfectly fine before the pcm swap.
I had this problem on one of my vehicles after i did a tranny swap… and ended up paying a shop to redo it all completely $3800 oversight and mistake… quite costly, and i watched your video and learned it for free
We ran 70 up I44, then all the 2 lane backroads on the cruise, and you'd never know it was a 45 year old truck. We had a blast. Glad we got to meet you guys! --Emily
8:45 I love all your videos they are very helpful , this is my first ls truck I didn’t swap the engine I swapped a 1973 gmc halfton onto a 2001 suburban or in the process anyway , but I’m having trouble finding the C1 block wiring diagram to match my 2001 suburban I’ve tried every where not sure if you have it not sure where to look thanks for your time
Great video. You have answered some of my questions without me even having to ask! But I have more questions--. My project is a 55 chevy, LT1 with a 4L60e swap . I want to keep the original speedometer. It is my understanding that by not having a digital speedo is the reason my transmission won't shift out of 1st. I've seen some kits where I can make it shift manually, but I would like it to be fully automatic. Any guidance you can give is greatly appreciated.
Your correct I'm stating how invaluable wiring diagrams are, especially for the wiring challenged like myself. Too bad one wasn't provided. I know you have a whiteboard. I've seen it.
Thank y’all for everything you do You’ve been a big help to me with my LS swap. Just need to know where to get power for transmission 2000 5.3 suburban 1500. I think F2 is transmission pin just need a power supply and maybe can finally drive my truck. Please Help. Thank you.
The 2000 5.3 is completely different when it comes to the transmission power. I am away from my shop today and will be back tomorrow. Will take a look at a diagram and get back to you. Jerry
Gearing up for a 6.0 4L80 from 2006 2500HD swap into an 85 C10. Any difference in 4L80 vs 4L60 for the wiring shown here for powering the shift solenoids? Same kind of install: factory fuse box, DBW, etc. Also curious about if cruise control hookup would be the same as your video and have TCC work. Just not seeing much for 4L80e’s. Thanks. PS, grew up in Spfd, Ozark and Sparta and love seeing such a good channel coming from the area!
It sounds like you are using harness and ecm from a 6.0 with a 4l80 behind it originally. If that is the case they are pretty much identical when it comes to wiring those items. If you we're going from a 4l60e to a 4l80 the plug needs rewired for the 4l80 but that's it.
I want to restore my dad's 76 c10. It use to have a 3 speed manual transmission but he changed it to a 350 hydromatic. The question I have is do I need to change the rear end on it. I can use a the help I can get thanks for the great videos.
Your rear differential should be fine. Odds are it may have a 3.08 rear gear ratio which will be fine with that thm350. A 3.73 would work also but would be more of a powerhouse than a cruiser. I bet it has a 3.08.
Love your videos. They have really helped my son and I work on his first truck. We are building a 77 C10 with a 5.3 from a 04 sierra. We are using the stock fuse box, harness and PCM. It is a DBW. Our issue is- the truck will start and idle all day with no issues. No check engine codes or anything. As soon as we give it throttle it acts like it is killing the injector pulse. I haven’t had a chance to try and verify this. We do still have ignition when this happens. We have replaced the tps the pedal and the maf. Any ideas on what to do next? Just curious if it was something related to the trans stuff we aren’t using. It does have a TH350 in it. Thanks!
Hello Brandon. I would check your fuel pressure first while opening the throttle to see what is happening at that point. If that maintains a good pressure it sounds like you might have injectors that are plugged up. Sometimes if that donor sat for a while with old fuel up in the rail, it can clog the injectors when you first go to start it. Shouldn't be anything with the transmission. Sounds like it is trying to bring the RPM's up when you open throttle and no codes, so I would think it is a mechanical issue that the ECM is going to have a hard time to detect. Send any questions and let me know what you find. Jerry
I just checked the fuel pressure and at prime it sits at 48psi. As soon at I start it up, it goes to 90psi. Even when the throttle cuts out it maintains 90psi. Any thoughts on this?
@@UglyTruckExperience that’s what i was thinking. I am using a walbro 255 in the tank and a corvette style filter regulator. I guess it could be bad. What issues might too much pressure cause?
Im working on getting a 4L80E running off a 2000 1 ton van computer set up for a 4L80e, and its swapped into a carb'd truck with an HEI Distributor. Ive got everything cept a tach signal because I dont know what to feed to either the crank or cam sensor signal line to the computer and I think Im going to try a 7 pin module to feed a square wave reference to one of the two sensor signal wires and see what happens. Im not sure but I think it needs a rpm signal for engine speed to wake up and make the shifting happen because everything else is wired right.
I have always wanted to try to do that with one of our carbureted trucks. Easiest thing would be to buy a controller for the transmission. Getting the tach signal would be difficult and getting transmission to shift correctly would be an issue I am sure. I would get a hold of somebody that tunes ECM's / TCM's and pick their brain for a bit. If you get one running great, make sure to let us know. Thanks. Jerry and Emily
@@UglyTruckExperience I actually managed to get the donor vehicle computer out of the 2000 1 ton van, to control the transmission and shift. Just had to get a tps kit online and set up a spare 7 pin module as a pickup signal converter to give the VCM the digital tach signal it was looking for. Kinda exciting because this was all done on the cheap.
@@UglyTruckExperience It should once I dial in the TPS just right like Im supposed to. Just did a functional mock up. Gonna clean up everything maybe over the weekend.
I have a 84 c10 4X4 and I did a ls swap with 4l60 trasmisión to it it work great but it only go on fist gear Y ready fix the trasmision and put another trasmissión and put a new computer new wire new sensers and it do the same thing
Howdy Folks - Where would a guy buy extra PINs to complete this project? I thought about using two extra wires I pulled from unused sections of the harness as they would be plug and play but it’s probably a better idea to start clean and use new wires and pins. Should I check GM’s part departments at a dealership, local parts stores like AutoZone, or find a supplier online? Lastly, what would I call that pin so I’m ensuring I order it correctly? Thanks as usual! Tony -
Hey Tony! Let me see if I can find a part number to order just the pins, but we just pull the unused pins and reuse them. Just make sure you're using a high quality, heat shrink, BUTT connector! 😆😉 --Emily
@@UglyTruckExperience See this is exactly what I wanted to do. I’m going to reuse items I have instead of throwing more money at the build 😂 Thanks, Emily!
Yep, exactly! 😁 Jerry and I were talking about this, and he also pointed out that unless you can find original GM pins, aftermarket pins may not fit as well and could cause a big headache if one had a bad connection.
Ok but how do I know which wire goes to the A and B solenoids? A lot of the wires have been cut from the original builder, so I can't tell which one to send the power through to get it to shift... Thanks for the video!
Hello Joe. The power that we are supplying in this video goes to a few different solenoids. They are turned on and off by the ECM by grounding whichever solenoids need to be on to apply the gears. If somebody has cut those wires you would need to make sure that all of those wires that had been cut are repaired. What is it that you are putting a LS in? Jerry
@@UglyTruckExperience 73 f100 with 2003ish 5.3 LS with 4L60E. "Stuck in 3rd" issue. Total hack job from previous owner. I'm trying to get this thing going down the road... I'm unsure which wires control the gear shifting solenoids. I think that's my next step of getting it to move...Thanks!
th-cam.com/video/COOzzFHCLRk/w-d-xo.html This is a link to a video that might help. If your working with a 2002 harness and box, you might just need to wire up some different wires. They are different from 2002 to 2003 and we go through that in this video. If that is not the case, I will do what I can to help. Thanks. Jerry
This is old I know and may have skipped over in the comments but anyway does this fix the needed pulse for the 4l60e to shift if using say a np208 transfer case? So it would eliminate the need for speedo signal? Hopefully that makes sense. Love what you two do! And love the content thanks in advance
Swap is done and truck is running I purchased a Dakota digital pulse generator , but have yet to install with the weather, this seems like a way easier way to fix the shift issue??
Hey Mangle! Great question! No, the wiring in this video just supplies power to the transmission shift solenoids. You'll still need a pulse signal for your speedo. Thanks for your comment, and thanks for watching!
Infected Mangle, I'm not using a transfer case as I am 2 wheel drive car, but it sounds like we have similar issues. If you figure something out let me know and I will so the same.
@@danieldalton9306 I plan to do some tinkering today I'm not stuck in third more like 1st but I will keep you posted on what I come up with, just for reference I purchased dakota digital sgi 100 bt and also dakota digital sen 01-1 the platform is a 85 k10 with 05 silverado 5.3 and 4l60e mated to a np208 ,
I have issues still after doing the same thing as your video. I have a c10 1984 with a 2005 engine 5.3 and transmission 4l60e . I cant take off on first moves forward a little bit But when I manual shift it runs good but I have to take off on 2nd shift. Ones I got speed I move it back to D DRIVE it and seems to be working good . ITS JUST THAT FIRST GEAR. DONT WAMT MANUAL SHIFT NO MORE LOL. FORGOT TO MENTION WIRING STOCK WITH STOCK FUSE BOX .

Jerry, could you check again on E2 connector 2? I have no wire there. E1 there are 2 blacks and E3 has a green. but nothing in E2. My E7 does have 2 orange for the rear 02 sensors. @@UglyTruckExperience
Need to figure out exactly what this wire harness and fuse box is from. Your wiring that you are describing doesn't make much sense looking at these diagrams. E7 should be 2 pink wires if they are going to the O2 sensors. Double check that you are reading the plug correctly. It can be confusing. Also, I can't find a instance of a Green wire in E3 on C2 for any of those years. Try to narrow down what this came from and let me know. Will do my best to help out. Jerry
One of the old wires has to go to the pcm and the other wires are a power and ground that I wire into the underwood fuse box. We will have a video on it pretty soon. Thanks. Jerry
One of the OBD wires has to go to the pcm and the other wires are a power and ground that I wire into the underwood fuse box. We will have a video on it pretty soon. Thanks. Jerry
Unfortunately my truck is not shifting still. I have it wired the same way you did in the video and pin E pink wire on the trans still doesn’t have power. I jumped the wire and it shifts but not great. 5.3/4l60e out of a 04 2wd suburban that ran and drove before being pulled. (Also seen that E11 c2 should have power which it does and c100 connector needs power on pin c tried that and still nothing)
Ok. If you have power at those two pink wires with key on you should have power down at the pink wire at the transmission connector position E. If you don't. You must have a break in the wire and possibly a problem with others that are loomed in the harness with it. That would possibly explain it's poor shifting when you jumped that wire. Jerry
Hey Felix. If you bought a standalone harness specifically for a swap, it should have power going to the transmission solenoids. I would go to the transmission plug and check for power with key on to begin with. Jerry
Hello Damien. This is supplying power to the shift solenoids and the powertrain control module to control it's shifting. The VSS get its power from the PCM. Jerry
Hello! Thank you very much for your videos. I'm in the middle of a swap. My base is a Jeep CJ7 (the front differential is on the passenger side) with a 5.3 LS engine and a 4L60 gearbox. Due to the side of the vehicle where the front differential is located, I chose to use an NP208 transfer case (1986 Bronco) and it uses a wire speedometer (analog type). What type of sensor should I use? I don't know how to adapt the speed sensor receiver from the wiring harness that goes to the PCM. did you have this problem? How would they solve it? thanks in advance.
We have only done 1 four wheel drive truck. On that truck I used an adapter between the transmission and transfer case that had a spot for electrical sensor and then also used the mechanical drive on the transfer case to run mechanical speedometer. I know they make a mechanical to electrical adapter that lets you continue on with the cable for the speedometer. That is most likely what I would end up doing. Here is an example of one. www.summitracing.com/parts/cin-sn96?seid=srese1&gclid=Cj0KCQjwlIG2BhC4ARIsADBgpVQtSnEb2iIeYm3Z-TlH_UV8YpSg6FD-3nBQ5aOWODXgenQh4JPHXIUaAtNKEALw_wcB
Not to make the transmission shift but in order for the TCC to engage you do have to wire the brake switches. We have another video on that subject, I will have Emily send you a link. Thanks
Hi Isaac! The donor for this video was a 2005, and your 2001 is a little different. Check out this video for 99-02 donor harness wiring. th-cam.com/video/COOzzFHCLRk/w-d-xo.html Hope this helps! Thanks for watching! --Emily and Jerry
Hoping you might shed a little light on a ls swap , computer is from a 2000 Tahoe and the trans is from a 07 Tahoe I have it all set up in a 1995 K1500 GMC trans seems to be only functioning on 2nd or 3rd gear ? Any Ideas
A 2007 Tahoe was right on the line when they started crossing into the GEN 4 wiring and the transmission had its own separate control module. It is possible to make that transmission work with the ECM that you have but will require some changes to the wiring depending on what you are using for a harness.
Check for power at the IGN 0 fuse with ignition in run position. If ok there. Check for power at D3 on connector 1. If that is good check for power at F2 on connector 2. If you have power at those pink wires with the ignition your transmission should shift. Let me know what you find after checking that. Jerry
So not sure what's different about my lq9 6.0 swap but I just did this and my truck wouldn't shut off I had to snip it to shut my truck off but I just had to top off fluids fell rite in gear crazy tho
Help me please if you can. Did a 5.3 swap from a 99 silverado into my 1997 GMC sierra. The truck shifts 1-2-3 just fine and then proceeds to just stay in 3rd after that. I can manually select 2nd and take off in second but once it intially goes 123 it stays in 3rd. I hooked up the rear o2 power into the shift solenoid wire at the transmission plug but that didnt fix it. Im stumped. Replaced 1-2 and 2-3 as well as the 3-2 shift solenoids. Also using a standalone harness. Everything functions on my truck gauges etc, but the tranny doesnt want to come out of limp home mode.
Hello, you have gained another fan in me! Can I connect my transmission from the O2 sensor spot like you did and keep my O2 sensors functional? I am hoping to keep everything as it came from the donor as much as possible, obviously transmission hook up would be one change. Thanks in advance @uglytruckexperience
Sure Ivan. You can keep those sensors just like they are. You would just need to find a different power source for the transmission. There are quite a few of them in that fuse box that you could use. Thank you for watching. We appreciate it. Jerry and Emily
Hello Scrapman. If your using a harness that was built for the engine and transmission that you are using, it should have power to the transmission like normal. When you get to the point of driving it and if it seems like it is stuck in third gear, check the correct pins at the transmission plug and see it has power with the key on. Let me know how it goes. Thanks. Jerry
Hey I had a question I have a 4l60 I did my swap with a Fitech standalone harness I’m getting 1/2/3 but not 4 gear I checked my solenoid I’m receiving power to 1-2 solenoid and 2-3 solenoid but not power on my pressure control solenoid is that something with the transmission harness or do I have to send power to the transmission just like you did
The pressure control solenoid doesn't have power going to it. There are 5 solenoids that have battery voltage going to them from that one circuit. 1-2, 2-3, 3-2, TCC and the TCC PWM Solenoid. What year is this transmission?
The original c10 did not have any wiring that goes to the transmission. Some of the later c10's had lock up torque converters in them that would have wires going to that but in the event of a ls swap those wires would just be eliminated. There would be no use for them in a swap. Thanks
The wiring for a 2002 is different from this one. We may have a video that covers that 2002 and earlier. Will have Emily send a link if I am correct. Thanks. Jerry
That 2003 wiring is hard to figure out. Your power to run the transmission comes from the IGN0 fuse. As long as you are using the original wiring harness you shouldn't have to do anything to get power to the transmission. If you have power with the key on at E11 on connector 2. It has two pink wires coming from it. Everything is good. Jerry
No, this circuit just supplies power to the transmission shift solenoids. Here's a link to the TCC! Thanks for watching! th-cam.com/video/yHUZ7JfQBbk/w-d-xo.html
Correction. I just noticed that your donor was a 01. On this one you will not need to do anything other than make sure your Ign0 fuse is good. Sorry for that. I should have read message better.
How would you do this on an 2004 6.0 4l80e in a 1984 C-10. Will not work like the 4l60e wiring info you shared. Have looked for trans wire diagram. Not much luck. Didn't know if you had any info?
@@UglyTruckExperience We found the problem we use the same solder connections as you. One had pulled apart could not see it with the shrink tube. Thank you Jerry for taken the time to get back to me!! And thank you for all the video's !!!
Hi UTX, do I need to give power to F10 & E11 of the C2 block to get my trans to shift? I hooked C9 up to a switched power distro block I have but I get no move😊when I put my truck in drive. I did get the following codes: P074, P0785 & P2761. Thanks in advance
Hello Robin. According to my diagrams. F10 is unused in that truck and E11 in connector 2 would need power with key on. That supplies power to the solenoids in the transmission. Did your transmission come from the 05 also? Jerry
@UglyTruckExperience for some reason, I am blowing fuses every time I step on the brake pedal. Should pin 85 in the relay for the torque converter lockup have 12v when the brake pedal is pressed?
Good morning, can you please advise me on my issue, I did my swap and used all parts from donor truck 2005 5.3 but the transmission is from a 2007 and the plug on the tranny is black instead of the green one, I wired it like shown in your video but I’m still stuck on 3rd
Hello Victor. In 2007 they changed the 4l60e. It has the PRNDL switch inside the transmission and does not use a pressure control solenoid valve. You are trying to mix and Gen 3 with a Gen 4 which can be a problem. You could check with whoever did your ECM programming and see if that computer can be made to control that system. If not, you will want to get a earlier transmission that matches your ECM and wire harness. Probably not what you wanted to hear. Let me know how it goes. Jerry
@@UglyTruckExperience Jerry you are the Man I did some research and you are confirming what a I found out, I just wanted to hear it from the expert , very appreciated Jerry in my next live I want to be your neighbor 👍
Thanks Victor. I hated to give you that reply, but at least you know what you are working with. If we were neighbors I would run over and help you swap that tranny out. Keep us posted on how it goes from here. Thanks Jerry
I'm doing mine now. Black box e7 to white box c9. The factory white box does not have a wire in that location. 1999 silverado ls 5.3 lm7 4l60e. I have complete donor vehicle. Going in a 1985 c10 Actually the only wire I have in common is the pink A-9 on the white box. Please help.
Ok on that truck you may not have to do anything but plug it in. On connector 2 which is black. Check for a pink wire in positions E2 and F2. On connector number 1, the white connector. Check for a pink wire at position D3. If all of those wires are there, you will just need to plug it in and make sure fuse IgnO fuse is good. Its a 10 amp fuse. If all is good, check for voltage at F2 on the black connector with key in run position. If you have 12 volts, all is good. If any of those wires are missing, let me know. The early truck wiring was way different. Jerry
Ok, I see what you have. The info on this wiring diagram is not great. This truck has another connector that is called connector 1. It is black in color and also plugs into the bottom of what is called the left bussed electrical center. It will have that pink D3 wire in it feeding your transmission. As long as that connector is plugged in you should be ready to go. Let me know if that is correct. Thanks, I learned something new on this one. Jerry
Thanks jerrry I got it to work I’m running original fuse block 2002 5.3 4l60 I got it to shut off got my main power key on off the ignition wire where u insert key so it shuts off now
Now my transmission won’t work original harness I’m going to swap those 2 pink wires to a key on power source to see if it will fix my problem no reverse just low one gear and have to give it gas
The wiring for a 2002 is totally different. The power for the transmission is already set up in the harness and fuse box, so if you are using the stock fuse box and harness you shouldn't have to do what we show in this video.
For the code you have, I think you don't have power going to your transmission. This video shows supplying power for a 2003 or later donor. If you're working with a 2002 or earlier harness and computer, check out this video. th-cam.com/video/COOzzFHCLRk/w-d-xo.html This shows how to supply power on the 2002 and earlier transmissions.

Thanks Terence! Will do! 😁
8:45 I love all your videos they are very helpful , this is my first ls truck I didn’t swap the engine I swapped a 1973 gmc halfton onto a 2001 suburban or in the process anyway , but I’m having trouble finding the C1 block wiring diagram to match my 2001 suburban I’ve tried every where not sure if you have it not sure where to look thanks for your time
Hi Brian! Is your truck a 4x4? Send us an email at uglytruckexperience@gmail.com and we should be able to help you out. Thanks for watching!
Great video. You have answered some of my questions without me even having to ask! But I have more questions--. My project is a 55 chevy, LT1 with a 4L60e swap . I want to keep the original speedometer. It is my understanding that by not having a digital speedo is the reason my transmission won't shift out of 1st. I've seen some kits where I can make it shift manually, but I would like it to be fully automatic. Any guidance you can give is greatly appreciated.
Hello Daniel. Which version of the LT1 engine are you using? Sbc version or LS based version.
Your correct I'm stating how invaluable wiring diagrams are, especially for the wiring challenged like myself. Too bad one wasn't provided. I know you have a whiteboard. I've seen it.
They really are. I would love it if they were all a little easier to get. They should come with the car like the owners manual does. Thanks
@@UglyTruckExperience Absolutely agree!
It helped me out. Thanks from Minnesota

Thank y’all for everything you do You’ve been a big help to me with my LS swap. Just need to know where to get power for transmission 2000 5.3 suburban 1500. I think F2 is transmission pin just need a power supply and maybe can finally drive my truck. Please Help. Thank you.
The 2000 5.3 is completely different when it comes to the transmission power. I am away from my shop today and will be back tomorrow. Will take a look at a diagram and get back to you. Jerry
Thank you very much
Hi Jerry just wondering if you had a chance to look at that diagram. Thank you
I got tied up but will look at it in just a bit.
Thank you Jerry
Gearing up for a 6.0 4L80 from 2006 2500HD swap into an 85 C10. Any difference in 4L80 vs 4L60 for the wiring shown here for powering the shift solenoids? Same kind of install: factory fuse box, DBW, etc. Also curious about if cruise control hookup would be the same as your video and have TCC work. Just not seeing much for 4L80e’s. Thanks. PS, grew up in Spfd, Ozark and Sparta and love seeing such a good channel coming from the area!
It sounds like you are using harness and ecm from a 6.0 with a 4l80 behind it originally. If that is the case they are pretty much identical when it comes to wiring those items. If you we're going from a 4l60e to a 4l80 the plug needs rewired for the 4l80 but that's it.
@@UglyTruckExperience yup, all matching donor items. Appreciate the help!
I want to restore my dad's 76 c10. It use to have a 3 speed manual transmission but he changed it to a 350 hydromatic. The question I have is do I need to change the rear end on it. I can use a the help I can get thanks for the great videos.
Your rear differential should be fine. Odds are it may have a 3.08 rear gear ratio which will be fine with that thm350. A 3.73 would work also but would be more of a powerhouse than a cruiser. I bet it has a 3.08.
Great info. Where are you guys located?

@@UglyTruckExperience im from Rio grande city Texas i wish i can take my 1984 k10 to do an ls swap , but to far for me
Love your videos. They have really helped my son and I work on his first truck. We are building a 77 C10 with a 5.3 from a 04 sierra. We are using the stock fuse box, harness and PCM. It is a DBW. Our issue is- the truck will start and idle all day with no issues. No check engine codes or anything. As soon as we give it throttle it acts like it is killing the injector pulse. I haven’t had a chance to try and verify this. We do still have ignition when this happens. We have replaced the tps the pedal and the maf. Any ideas on what to do next? Just curious if it was something related to the trans stuff we aren’t using. It does have a TH350 in it. Thanks!
Hello Brandon. I would check your fuel pressure first while opening the throttle to see what is happening at that point. If that maintains a good pressure it sounds like you might have injectors that are plugged up. Sometimes if that donor sat for a while with old fuel up in the rail, it can clog the injectors when you first go to start it. Shouldn't be anything with the transmission. Sounds like it is trying to bring the RPM's up when you open throttle and no codes, so I would think it is a mechanical issue that the ECM is going to have a hard time to detect. Send any questions and let me know what you find. Jerry
@@UglyTruckExperience thanks Jerry, I will give that a try and see what happens.
I just checked the fuel pressure and at prime it sits at 48psi. As soon at I start it up, it goes to 90psi. Even when the throttle cuts out it maintains 90psi. Any thoughts on this?
It sounds like whatever you are using for a fuel pressure regulator is not working. It should stay at around 58 PSI no matter what.
@@UglyTruckExperience that’s what i was thinking. I am using a walbro 255 in the tank and a corvette style filter regulator. I guess it could be bad. What issues might too much pressure cause?
Im working on getting a 4L80E running off a 2000 1 ton van computer set up for a 4L80e, and its swapped into a carb'd truck with an HEI Distributor. Ive got everything cept a tach signal because I dont know what to feed to either the crank or cam sensor signal line to the computer and I think Im going to try a 7 pin module to feed a square wave reference to one of the two sensor signal wires and see what happens. Im not sure but I think it needs a rpm signal for engine speed to wake up and make the shifting happen because everything else is wired right.
I have always wanted to try to do that with one of our carbureted trucks. Easiest thing would be to buy a controller for the transmission. Getting the tach signal would be difficult and getting transmission to shift correctly would be an issue I am sure. I would get a hold of somebody that tunes ECM's / TCM's and pick their brain for a bit. If you get one running great, make sure to let us know. Thanks. Jerry and Emily
@@UglyTruckExperience I actually managed to get the donor vehicle computer out of the 2000 1 ton van, to control the transmission and shift. Just had to get a tps kit online and set up a spare 7 pin module as a pickup signal converter to give the VCM the digital tach signal it was looking for. Kinda exciting because this was all done on the cheap.
That is cool.. Does it shift nicely? Jerry
@@UglyTruckExperience It should once I dial in the TPS just right like Im supposed to. Just did a functional mock up. Gonna clean up everything maybe over the weekend.
Great video but what color is the wire on the transmission harness. Or what pin on the circle transmission connector
Thanks Tylor! That wire is pink. It is pin E in the round connector at the transmission. We appreciate you watching!
@@UglyTruckExperience thanks
I have a 84 c10 4X4 and I did a ls swap with 4l60 trasmisión to it it work great but it only go on fist gear Y ready fix the trasmision and put another trasmissión and put a new computer new wire new sensers and it do the same thing
Have you made sure there is power going to the wires that I describe in this video?
Howdy Folks - Where would a guy buy extra PINs to complete this project? I thought about using two extra wires I pulled from unused sections of the harness as they would be plug and play but it’s probably a better idea to start clean and use new wires and pins. Should I check GM’s part departments at a dealership, local parts stores like AutoZone, or find a supplier online?
Lastly, what would I call that pin so I’m ensuring I order it correctly?
Thanks as usual!
Tony -
Hey Tony! Let me see if I can find a part number to order just the pins, but we just pull the unused pins and reuse them. Just make sure you're using a high quality, heat shrink, BUTT connector! 😆😉 --Emily
@@UglyTruckExperience See this is exactly what I wanted to do. I’m going to reuse items I have instead of throwing more money at the build 😂
Thanks, Emily!
Yep, exactly! 😁 Jerry and I were talking about this, and he also pointed out that unless you can find original GM pins, aftermarket pins may not fit as well and could cause a big headache if one had a bad connection.
Is the battery cables wire video coming soon?
Won't be to long, about to the point of setting the engine and trans in there and will do that right after.
@@UglyTruckExperience ok thanks because is one of the last thing I need to finish my swap
great video s question im using a 2000 silverado ls swap what wire do I use for the transmission hot stock harness and fuse box
Connector 2, position F2 has 2 pink wires going to it. Those two wires will need power on with key on. Thanks. Jerry
Ok but how do I know which wire goes to the A and B solenoids? A lot of the wires have been cut from the original builder, so I can't tell which one to send the power through to get it to shift... Thanks for the video!
Hello Joe. The power that we are supplying in this video goes to a few different solenoids. They are turned on and off by the ECM by grounding whichever solenoids need to be on to apply the gears. If somebody has cut those wires you would need to make sure that all of those wires that had been cut are repaired. What is it that you are putting a LS in? Jerry

th-cam.com/video/COOzzFHCLRk/w-d-xo.html This is a link to a video that might help. If your working with a 2002 harness and box, you might just need to wire up some different wires. They are different from 2002 to 2003 and we go through that in this video. If that is not the case, I will do what I can to help. Thanks. Jerry
This is old I know and may have skipped over in the comments but anyway does this fix the needed pulse for the 4l60e to shift if using say a np208 transfer case? So it would eliminate the need for speedo signal? Hopefully that makes sense. Love what you two do! And love the content thanks in advance
Swap is done and truck is running I purchased a Dakota digital pulse generator , but have yet to install with the weather, this seems like a way easier way to fix the shift issue??
Hey Mangle! Great question! No, the wiring in this video just supplies power to the transmission shift solenoids. You'll still need a pulse signal for your speedo. Thanks for your comment, and thanks for watching!
Infected Mangle, I'm not using a transfer case as I am 2 wheel drive car, but it sounds like we have similar issues. If you figure something out let me know and I will so the same.

Will look again..Be right back. Jerry
You said 99-02. Do you know what year for sure you are working with?
Need to figure out exactly what this wire harness and fuse box is from. Your wiring that you are describing doesn't make much sense looking at these diagrams. E7 should be 2 pink wires if they are going to the O2 sensors. Double check that you are reading the plug correctly. It can be confusing. Also, I can't find a instance of a Green wire in E3 on C2 for any of those years. Try to narrow down what this came from and let me know. Will do my best to help out. Jerry
Great videos I have ? how do you wire the obd2 port do you go to the pcm or can you wire it to the under hood fuse box
One of the old wires has to go to the pcm and the other wires are a power and ground that I wire into the underwood fuse box. We will have a video on it pretty soon. Thanks. Jerry
One of the OBD wires has to go to the pcm and the other wires are a power and ground that I wire into the underwood fuse box. We will have a video on it pretty soon. Thanks. Jerry
Unfortunately my truck is not shifting still. I have it wired the same way you did in the video and pin E pink wire on the trans still doesn’t have power. I jumped the wire and it shifts but not great. 5.3/4l60e out of a 04 2wd suburban that ran and drove before being pulled. (Also seen that E11 c2 should have power which it does and c100 connector needs power on pin c tried that and still nothing)
Hello JD. Does your E11 on C2 have two pink wires coming from it? Jerry
@@UglyTruckExperience yes it does
Ok. If you have power at those two pink wires with key on you should have power down at the pink wire at the transmission connector position E. If you don't. You must have a break in the wire and possibly a problem with others that are loomed in the harness with it. That would possibly explain it's poor shifting when you jumped that wire. Jerry

What if you have a standalone harness? And transmission doing the same thing?
Hey Felix. If you bought a standalone harness specifically for a swap, it should have power going to the transmission solenoids. I would go to the transmission plug and check for power with key on to begin with. Jerry

Hello! Thank you very much for your videos.
I'm in the middle of a swap. My base is a Jeep CJ7 (the front differential is on the passenger side) with a 5.3 LS engine and a 4L60 gearbox.
Due to the side of the vehicle where the front differential is located, I chose to use an NP208 transfer case (1986 Bronco) and it uses a wire speedometer (analog type). What type of sensor should I use?
I don't know how to adapt the speed sensor receiver from the wiring harness that goes to the PCM.
did you have this problem? How would they solve it?
thanks in advance.
We have only done 1 four wheel drive truck. On that truck I used an adapter between the transmission and transfer case that had a spot for electrical sensor and then also used the mechanical drive on the transfer case to run mechanical speedometer. I know they make a mechanical to electrical adapter that lets you continue on with the cable for the speedometer. That is most likely what I would end up doing. Here is an example of one. www.summitracing.com/parts/cin-sn96?seid=srese1&gclid=Cj0KCQjwlIG2BhC4ARIsADBgpVQtSnEb2iIeYm3Z-TlH_UV8YpSg6FD-3nBQ5aOWODXgenQh4JPHXIUaAtNKEALw_wcB
@@UglyTruckExperience thanx!!
Did you guys have to use the tcc brake switch wire pin 33
Not to make the transmission shift but in order for the TCC to engage you do have to wire the brake switches. We have another video on that subject, I will have Emily send you a link. Thanks

Hoping you might shed a little light on a ls swap , computer is from a 2000 Tahoe and the trans is from a 07 Tahoe I have it all set up in a 1995 K1500 GMC
trans seems to be only functioning on 2nd or 3rd gear ? Any Ideas
Is it a 4l60 transmission?
Also, what is your wiring harness?
A 2007 Tahoe was right on the line when they started crossing into the GEN 4 wiring and the transmission had its own separate control module. It is possible to make that transmission work with the ECM that you have but will require some changes to the wiring depending on what you are using for a harness.
Sorry I looked into this a little more and the donor transmission is a 2002 Tahoe, iam sure that will change things a little. Ideas?
Check for power at the IGN 0 fuse with ignition in run position. If ok there. Check for power at D3 on connector 1. If that is good check for power at F2 on connector 2. If you have power at those pink wires with the ignition your transmission should shift. Let me know what you find after checking that. Jerry
Hey... I have to press on my gas for 5 to 10 seconds for my engine to stay crank at startup...what could that possibly be?
Hey Terry. Look at your fuel pressure first. Jerry
Would this apply if im using a Holley Terminator X max ? just did a ls swap with a 4L80 and it is also stuck in 3rd gear
If you bought the Terminator x max with 4l80 control, I don't believe you would have to do this.

Help me please if you can. Did a 5.3 swap from a 99 silverado into my 1997 GMC sierra. The truck shifts 1-2-3 just fine and then proceeds to just stay in 3rd after that. I can manually select 2nd and take off in second but once it intially goes 123 it stays in 3rd. I hooked up the rear o2 power into the shift solenoid wire at the transmission plug but that didnt fix it. Im stumped. Replaced 1-2 and 2-3 as well as the 3-2 shift solenoids.
Also using a standalone harness. Everything functions on my truck gauges etc, but the tranny doesnt want to come out of limp home mode.
Hello jsbird. Are you using the ECM from the 99 to control both the 5.3 and the 4l60? Jerry
Hello, you have gained another fan in me! Can I connect my transmission from the O2 sensor spot like you did and keep my O2 sensors functional? I am hoping to keep everything as it came from the donor as much as possible, obviously transmission hook up would be one change. Thanks in advance @uglytruckexperience
Sure Ivan. You can keep those sensors just like they are. You would just need to find a different power source for the transmission. There are quite a few of them in that fuse box that you could use. Thank you for watching. We appreciate it. Jerry and Emily
Will i have this issue if I’m using a standalone harness it seem as if your using a factory harness and fuse box
Hello Scrapman. If your using a harness that was built for the engine and transmission that you are using, it should have power to the transmission like normal. When you get to the point of driving it and if it seems like it is stuck in third gear, check the correct pins at the transmission plug and see it has power with the key on. Let me know how it goes. Thanks. Jerry
Did you figure it out with standalone?
Hey I had a question I have a 4l60 I did my swap with a Fitech standalone harness I’m getting 1/2/3 but not 4 gear I checked my solenoid I’m receiving power to 1-2 solenoid and 2-3 solenoid but not power on my pressure control solenoid is that something with the transmission harness or do I have to send power to the transmission just like you did
The pressure control solenoid doesn't have power going to it. There are 5 solenoids that have battery voltage going to them from that one circuit. 1-2, 2-3, 3-2, TCC and the TCC PWM Solenoid. What year is this transmission?
What ever happened to the original c10 wires
The original c10 did not have any wiring that goes to the transmission. Some of the later c10's had lock up torque converters in them that would have wires going to that but in the event of a ls swap those wires would just be eliminated. There would be no use for them in a swap. Thanks
Does this wire that needs power happen to be a thicker purple wire? The harness I got doesn't have the fuse box plug on it.
What is your harness and computer. Donor make model and year?
@@UglyTruckExperience pretty sure it's from a 2002 tahoe.

That 2003 wiring is hard to figure out. Your power to run the transmission comes from the IGN0 fuse.

Hello Victor. In 2007 they changed the 4l60e. It has the PRNDL switch inside the transmission and does not use a pressure control solenoid valve. You are trying to mix and Gen 3 with a Gen 4 which can be a problem. You could check with whoever did your ECM programming and see if that computer can be made to control that system. If not, you will want to get a earlier transmission that matches your ECM and wire harness. Probably not what you wanted to hear. Let me know how it goes. Jerry

I'm doing mine now. Black box e7 to white box c9. The factory white box does not have a wire in that location.
1999 silverado ls 5.3 lm7 4l60e.
I have complete donor vehicle.
Going in a 1985 c10
Actually the only wire I have in common is the pink A-9 on the white box.
Please help.
Ok on that truck you may not have to do anything but plug it in. On connector 2 which is black. Check for a pink wire in positions E2 and F2. On connector number 1, the white connector. Check for a pink wire at position D3. If all of those wires are there, you will just need to plug it in and make sure fuse IgnO fuse is good. Its a 10 amp fuse. If all is good, check for voltage at F2 on the black connector with key in run position. If you have 12 volts, all is good. If any of those wires are missing, let me know. The early truck wiring was way different. Jerry
Black box has the pink wire in those locations. White box has a yellow at d3
Ok, I see what you have. The info on this wiring diagram is not great. This truck has another connector that is called connector 1. It is black in color and also plugs into the bottom of what is called the left bussed electrical center. It will have that pink D3 wire in it feeding your transmission. As long as that connector is plugged in you should be ready to go. Let me know if that is correct. Thanks, I learned something new on this one. Jerry
Thanks for trying to help. I gave up and ordered a harness.
No problem. Let us know how it is going.
Hi I did a ls swap on my 1972 c10 but I can’t get it to shutoff I have to disconnect battery wire or wire going to pcm original fuse block please help
What is your donor motor, fuse box and harness. Jerry
Thanks jerrry I got it to work I’m running original fuse block 2002 5.3 4l60 I got it to shut off got my main power key on off the ignition wire where u insert key so it shuts off now
Now my transmission won’t work original harness I’m going to swap those 2 pink wires to a key on power source to see if it will fix my problem no reverse just low one gear and have to give it gas
The wiring for a 2002 is totally different. The power for the transmission is already set up in the harness and fuse box, so if you are using the stock fuse box and harness you shouldn't have to do what we show in this video.
@@UglyTruckExperienceso I don’t have to do anything to it still takes off in third gear
Hey mine won't shift out of first gear do you think I have the same problem I can manually shift it but it's not shifting automatically
Hi Tristen. No, if you have first gear, your solenoids have power already. Are you working on a swap? What was your donor vehicle?
@@UglyTruckExperience yea it's a swap it's a 1991 chevy silverado 1500
What did the engine and transmission come out of? What are you using for a harness and fuse box?
@@UglyTruckExperience 1999 chevy silverado using a standalone harness I did it myself so that could be the problem lol
Hello Tristen. Did you get this figured out. If not I would look into whether or not you are getting a speed signal to your pcm. Jerry
What code were you getting?
I don't believe there were any codes, just stuck in 3rd. Are you having issues with your swap?
@@UglyTruckExperience yes would appreciate the help having code p0785 time/shift
What was your donor harness and fuse box?
For the code you have, I think you don't have power going to your transmission. This video shows supplying power for a 2003 or later donor. If you're working with a 2002 or earlier harness and computer, check out this video. th-cam.com/video/COOzzFHCLRk/w-d-xo.html This shows how to supply power on the 2002 and earlier transmissions. Hope this helps. Let us know! --Jerry and Emily
@@UglyTruckExperience I think I'm going to change sensor 3-2 I had already followed your steps to get power to transmission I am getting power , I checked the solenoid reads 21.6
Hey I did mine the same way and it still won’t shift it got power on the E pin plug on the transmission but not A-B for the solenoid
What is your donor motor, transmission, harness and fuse block? Jerry
05 avalanche 5.3 2wd 4l60e in my 93c1500
Pin E, which should be Pink wire would be the only one with power except for the Red wire in C that goes to the pressure control solenoid. Is your truck stuck in 3rd gear or is it in 1st and does not shift? Jerry
It’s in 1st gear won’t shift I try down shift still not nothing
Do I need power to the btsi fuse
Hey I know this post kind of old but I have an LS Swap 1992 3rd gen camaro. I have a LS1 with the factory harness and fuse box harness from out of a 2002 firebird trans am and I can’t get my transmission to shift or speedo working.. do I need to do what you did if so can you help me out by letting me know what I need to do on my fuse box or anything
I’m also running 4l60e behind it
I will take a look at that wiring this afternoon and get back to you.
@@UglyTruckExperience ok really appreciate it
Did the donor transmission come from the same car or did this car have a manual transmission? Any info helps
@@UglyTruckExperience The motor and transmission came out of two different Fbody’s
for some reason , i wanna yell BINGO !! ..hmm
🤣🤣🤣
Actually everything is good just collecting data for possible future problems.
Like your videos on ls swaps. What do you use for dbw gas pedal? I saw a vid on using a 94-01 6.5 l diesel pedal, swapping pin a and e, and slotting the plug: th-cam.com/video/WX1XNADiWRg/w-d-xo.html. Any thoughts?
I use a standard that is on most of these trucks and suv's. I cut the pedal off in a particular area and move it about 5 inches to the left. Use the original mounting holes in the firewall and adjust the pedal to be at wot mashed to the floor. We will do a video soon. Thank you for watching. Jerry
What pin/pins do I need to wire to my brake switch so the torque converter unlocks when I'm on the brake at a stop?
