Wiring LOCKUP TORQUE CONVERTER for LS Swap - UTX

- เผยแพร่เมื่อ 12 ก.ย. 2024
- Today at Ugly Truck, we're wiring up the TCC on our LS swapped 1970 C10. When we swapped this truck, we were a little impatient and never finished the wiring for the lock-up torque converter, so today's the day! This truck has a 4L60E transmission, and the wiring harness and fuse box from a 2004 Tahoe, which makes it easy to steal power from the stop lamp fuse and use it to power up our torque converter. The tricky part is tying into the original C10 brake light switch to disengage the TCC, but we've said it before... RELAYS ARE FRIENDS!!

I really love how y’all broke the ls swap made easy down for everyone to know thank you both for your knowledge on educating us please don’t stop sharing ok ❤
Thanks so much for your comment! We have a bunch of LS swap videos coming up soon! We appreciate you watching!
THis has helped me figure out a non converter related wiring dilemma ive been trying to figure out for my Nitrous set up. Thanks professor Jerry.
Torque converters are important, but nitrous is importanter. 🤣🤣 How did Squeaky do at NNN? We need to get together again one of these days!
@@UglyTruckExperience squeaky did great, until he didn't, then he did great again. It was a roller coaster ride Friday
Can't wait to check out the videos! 👍
I like the way yours do your videos you explain it
Thank you! We appreciate you watching!
I love these video's you post. I've done many swaps but I have always used aftermarket systems both carb and TB EFI so I literally have a pile of truck intakes, Gen 3 and a Gen 4 DBW harness and PCM's all boxed up taking up space so you have encouraged me to sacrifice one of the Gen 3's to cut down and rewire the harness myself. I have a '88 S10 that's crying for a 4.8 I have and a T5 WC out of a '88 Camaro, the stock PCM and harness would be perfect for it. (low buck) Now just to find a 'vette intake and accessory drive, another bug hunt and reengining project. Please keep up the video's, they really help.
That's awesome! I had a 4.8 in my yellow 70 C10 before we put the 5.3 in, and I loved it. The 5.3 has been great, but the 4.8 was pretty snappy. Keep us posted! A 4.8 in an S10 will be fun! --Emily

Thank you for showing me how to do some this wiring, good job
We're glad to help! Thanks for watching! 👋
Yeah, you broke 4k. Love the close ups on the BUTT connectors. Hard to believe a crimp isn't required. I just put a new headlight switch in my 72 k10. I found a headlight harness that draws power directly from the battery instead of through the switch. Hopefully I don't have to do it again, that switch is bad to access and hard to get the knob removed
We've been talking about upgrading our camera, so the BUTT connector close ups might get even better! 😁 And I'm in a similar situation with that switch... My tail lights only work if you have it in just the right spot, but it's such a bear to get to I've never bothered to fix it. We've had that dash and steering column out a dozen times, and every time we say it's the last time. 🤣 Thanks for watching, Bill!!
Thanks for sharing. Best to You and Yours.
Thanks for watching! Same to you! 👋
I am applying the 'Torque-Converter Lockup' to my 1995 Toyota Camry. 1st timer here. LOL! But I want to get it right the 1st time. Your video has been a real help, but I'm not 100% confident in making that step as of yet because there are several different variations on how to do this and I want the best solution for my car. But, I don't know what that is right now. I've watched video of people adding a TCC Dual switch, and I've watched them add a 2nd Brake Switch.
Hi Garry, are you LS swapping a 95 Camry?
LOL! @@UglyTruckExperience I'm not, I just want to adapt the 'Torque-Converter Lockup' into my daily driver to get better fuel economy. I don't have neither the time or resources to do anything as extreme as engine swapping and converting a FWD to a RWD. Though I'm sire it's be a rocket on wheels. LOL!
@@UglyTruckExperience I'm re-reviewing your video and at 5:00 mark it occurred to me that one should be able to jump from the Cruise-Control wiring to the PCM/TCM to activate the Torque-Converter LockUp. Would that be a safe assumption?
Thank you very much
. It is a two piece connector the one with the wires and the one that's stays put on granny does the one on the transmission also pop out.
The one on the transmission side pulls out through the bottom, so you will have to pull the pan to get it off.
Love the dogs eyes another great video
She's the real star around here! 😁 Thanks for watching!
Thanks for the videos and ya'll are great 👍 👌 😀
We appreciate you watching, Randy! 👍👍
Thank y’all so much for sharing your knowledge! I’m currently planning an LS swap for my 76 C10 that my grandad gave me before he passed a few years ago. One thing I’m trying to figure out is gauges. Do you maintain the factory gauges in your Ls swaps? What’s the wiring/hookups for that look like?
Thanks
Thanks for watching! We've kept the factory gauges on the last few swaps that we've done, and on my 70 C10. I'll have to find you some links, but there's an oil pressure adapter that goes from the original gauge to the oil cooler lines on the LS. I believe ICT or LSX makes them. We use a temp sensor adapter that goes in the passenger side cylinder head, also ICT. Here's a link for the speedometer. We used a Dakota Digital adapter and it's been great! th-cam.com/video/hLqXYWG_WhY/w-d-xo.html
Thanks for your questions, and we appreciate you watching! 👋. --Emily
Thanks! I’ll check around for those adapters!
I would prefer adding a second brake switch or replacing the brake switch with one that has NC and NO switches inside. That way you eliminate the relay, and are not dependent on it to function to unlock the torque converter. But hey, this works fine... until it doesn't. O_O
If these we're my own vehicles, I may do that. When these trucks leave us they could get a few years down the road and need a new brake switch here and there. I try not to mess with it's original switches or add in the event something needs replaced in the future. If they run it to a mechanic and they can't figure out that a relay has failed, I hope they take it to another shop. Thanks for watching. We appreciate it. Jerry and Emily
Good afternoon UTX, I am doing my first LS swap and you have helped immensely. My car is up and running and I’m working on hooking up the torque converter wiring. I have done exactly what your video says but cannot get the scan tool to tell me that the TCC is enabled. The only difference between my build is that my ecu and wiring came from a 2000 suburban (LM7) and yours came from a 2004 Tahoe. Does this make a difference? The pin out on the 2000 says 33 is indeed the TCC input.
Hello Carl. The wiring for a 2000 is quite a bit different. I will look at that this afternoon and get back to you. Jerry
Looks like the wiring for the TCC is exactly the same. Power to 33 would be all you need to get TCC to lock up. Scan tool won't show enable until above 45 mph at least. I have taken some for a drive and had to drive them a good amount before it would show enabled. Will your scan tool show you a Data on whether ECM is showing that brake signal? Jerry
@@UglyTruckExperience Jerry, I figured it out. I had to check continuity from a pin 33 on the blue ECM connector and found it went to another plug, not up into the fuse box. I haven’t driven it yet but my scan tool is showing exactly what you showed in the video. Thank you so much!
Great!! Nice Job. Jerry

Like your youtube channel when are you going to do ls swap on a 1996 chevrolet silverado truck
LS swaps on OBS trucks have gotten really popular. I'm sure we'll have some videos on that someday soon. Thanks for watching!
On my LS swap I am experiencing what appears to be a torque converter that STAYS locked up. When I come to a stop it is dragging the engine down and you have to hold very firm on the pedal to keep it stopped. It is so bad that sometimes if you stop relatively quickly it will stall the motor, you can watch the RPM's drop below idle speed. I am running a 4L65E OEM CPU, and custom aftermarket Speartech wiring for engine / transmission controls. The directions indicate one "control wire" from the CPU to the brake switch "to normally closed brake switch, zero volts when brakes are APPLIED." Thoughts? Thanks.
Hi Dave, have you tried disconnecting the power going to the brake switch and see what changes?
@@UglyTruckExperience Yes, Thanks I did, but no real changes. I am going to see my transmission builder this coming week. Appreciate your time.
Let us know how it goes! We've never used an aftermarket harness, so I'm curious what the issue might be here. Thanks for watching!
@@UglyTruckExperience Funny you should say that, just got off the phone with a local tuner that will be hopefully be doing a complete tech tune on the drive-line, and the weird trans issue will come up along with that. This is a recent LS swap, so big learning curve. Thanks again.
Did you ever figure the problem out Dave? I'm having the same issue now with 4l80e converter staying locked up.
I have a question on my 350 trans with a blue plug lock up connection I guess but does it have a o ring because it leaks from this connection when I add fluid because it's low but then it leaks any advice?
Hi Jesse! Yes there is an o-ring seal on that connector and they are known to leak over time.
Hi guys you are the best at this …quick question on this for a 99-02 what spot is for my 87a because my connector 1..C12… it doesn’t have a pin sticking out on the fuse box ..it’s a blank spot… thanks sorry for the bother
Hello Kenneth. Sorry to just respond. What is your donor harness and fuse box from and are you just trying to get torque converter to lock up? Jerry
@@UglyTruckExperience it’s a 02 Tahoe Canadian harness with flex fuel sensor …. right now I just have the 87a coming off the relay and going down to the blue ecm plug and just spliced in like 3 inches from the pcm plug … seems to work but I saw in the comments that others have used this on the 02 but I don’t see how unless my harness is a one off which doesn’t seem to be …. But it’s got the Canadian o2 sensor plugs all 4 are the white square
Willie wiring that you're showing work on an 88 also
It would depend on what you are swapping. What is donor engine and transmission?
Keep up the good work. Quick question... for my 87 montecarlo ss & im wiring up my TCC/Brake switch, how do I get my brake switch to work with the car running... my car cuts off when i press the brakes
Hey Terry. Not sure why your car would die with the brake applied? Did it always do that or did it start when you wired in the TCC? Jerry
thank you! you guys have been loads of help...now if whoever removed the engine from my car hadn't unhooked the wiring with a hatchet...🪓
Thanks Ronald! Not sure a hatchet is the best tool for the job, but I bet they got it done in a hurry! 😆 We appreciate you watching our stuff, and best of luck on your project! --Emily and Jerry

What if 85 on the relay is used as a ground instead of 86 for the brake switch?
Hello Terry. Pin 85 and pin 86 can be used either way. Thanks for watching. Jerry and Emily
Hello. I’m running a terminator x max on a 1992 Chevy c1500 with the 4 pin oem brake switch. Currently, my grey wire for the tcc lockup is connected to the purple wire at the brake pedal. Would I need to change to a different brake switch and wire in a relay like you have here?
Hello Kabarrion. My wiring diagrams for a 92 are not the best but It looks like the purple would be hot with your foot off the brake and then off when brake applied, so that should be all you need for the TCC. Thanks for watching. Let us know how it goes. Jerry and Emily
Yall have been helpful on so much but I’m wanting to put one in my 92 Silverado would it all work the same way
Hello Travis. The Silverado will have some different challenges when it comes to getting your gauges to work. For the most part, the LS swap will depend on what your donor motor, harness, and fuse box will be. If you don't already have a donor, do yourself a favor and try to stick with a Gen 3. Thanks for watching. We appreciate it. Jerry and Emily
@@UglyTruckExperience thank u very much that’s what I was wondering what would be the best gen ls
Hello. I have a psi harness and on the instructions it asks for the tcc wire to be wired into the brake switch. But it wants it to be 12v when brakes are applied. Is that correct?
Yes, I recently wired a psi harness and remember running the 12 volt brake signal to that harness. Jerry
I have a 87 that I’m swapping to 6.0/4l80e combo out of a 02 suburban .. since I had the 700r4 previously is there existing wiring I can you or is this video the route I need to go?
You would want to use the wiring from your 02 suburban on that one. It would be much easier to wire. Thanks. Jerry
Love y'all's content. Question I have a 2 sided brake switch not doing a relay. So would I splice in to the purple wire that's coming from the ecm to brake switch?, and also being DBW I think there is a yellow wire from the TAC Module I splice into it and go to the brake side od switch and splice into it right? It will be 3 wires instead of 2
Hello Tommy. Sounds like you have it wired correctly. Would need to know that your donor and truck you are swapping into for sure. Jerry
@@UglyTruckExperience the truck is a 1986 C20 it had a 350 and a turbo 350 with a lock up converter.. LS engine I used. 2007 Lq4 6.0 4l80e DBW out of HD
Is this a Gen 4 with a separate computer for the transmission?
@@UglyTruckExperience no sir its a gen 3
@@UglyTruckExperience used factory ecm and wiring harness that came with the motor.

Hi Alonso! 👋👋
question.... i'm getting ready to wire up this tcc circuit in my swap. I was going to do it without the relay by getting one of those brake switches that has the brake switch in it and the switch that was power until the peddle is depressed to use for the tcc.. Is one way better than the other? Also, I was concerned about having constant unkeyed power from the brake light circuit, vs having keyed power to the tcc circuit. Possible battery drain from having that circuit constantly activated?
Also, I'm using the cruise control from the 2004 silverado donor. Would I even need to do the brake switch circuit? Is the computer going to use the data from the cruise control and tac module circuit for the tcc lock up?
Hello Bill. If you wire up your cruise control, that will make your TCC circuit work also. Fixing two things at once. Jerry
@@UglyTruckExperience I looked at you cruise control video and it's totally different than what I'm doing so I'm scratching my head. I'm putting this in a 61 Pontiac...... 4.8 from a 2004 Silverado using the Silverado harness, under hood fuse box, drive by wire pedal, tac module and the signal lever mounted cruise control switch which I modified to mount under the dash. . I used the wires from the switch that run through the C100 connector to the pcm. I think all I need to do is wire power to the cruise control switch (brownwire) , then also run power to the dual function brake switch that supplies power to tcc purple wire that goes to C1,C12 then to the 33 pin on the pcm. Does this sound right?
That sounds right. In this video I was wiring it without a dual function switch. Doing it the way you described will work fine. Let us know how it goes. Thanks. Jerry and Emily
My brakes on my gbody montecarlo cuts the car off when pressed while running in park... also the brake lights only light up while car is off, but not when it's on... how do I get the brake lights to work when car is running?
Hey Terry. I would have to know more about how it is wired to give you a helpful answer. That being said, I think I would go back to the brake light circuit and separate it from the ls swap and make both systems work individually from each other. Once both systems are working correctly. You could start incorporating the systems together which would give you an idea of the problem as you go back together with them. Jerry
@@UglyTruckExperience From what I noticed, the guy who did my LS swap have the purple tcc wire from (PSI Harness/ computer) going to purple cruise control wire above brake pedal... but somehow my fuel pump makes a sound when I release brake pedal as well.... Thanks! Now I did wire up my reverse lights from 4l60e trans to montecarlo reverse lights wire and works fine
Can I use a 4 pin relay instead of the 5 pin? Would it wire up basically the same?
Hello Richard. In this case you would have to use a 5 pin relay.. On a 5 pin 30 and 87a have a connection until the relay is energized. Pin 87 on a 4 pin only has connection with relay energized. Hope that makes sense. Thanks. Jerry
@UglyTruckExperience Thank you Jerry, I appreciate your help. Keep those great videos coming, with that awesome content!!!
Is this needed for a 4l80? Or is it just 4l60? Engine came from 2002 escalade 6.0 awd , putting a 4l80 rwd
Most 2002 donors we're a bit different. On some of them you don't have to do anything at all but plug in C2 and C1. and your good to go. If you have problems, let us know and I will take a look at a diagram. Thanks. Jerry
Sounds good thank you for replying, appreciate your time 🙏
Question do I have to do the same way you did. If I have a 2 sided brake switch already cause my truck came with cruise control 1986 C20 it came with a 3 speed auto? But I'm doing a ls swap 2007 lq4 dbw 6.0 4l80e trans
Hello Tommy. You can do that and I am actually going to be doing that soon to our own truck. We don't do it in the video, just to keep cruise and the trucks original brakes completely separate. Most swaps don't have an NO and a NC switch, so we thought this would help the larger majority get cruise. Thanks. Jerry
@@UglyTruckExperience ok cool deal. I just figured I would ask.
I love y'all's videos. They have helped me alot
Can't wait to see the video your talking about.

I have a 86 c10 with a 5.3 and 4l80e I am having a problem with the converter locking up at around 5mph and stays locked in. I have the brake switch from bp auto wired up per instructions and it does not disengage the converter either. Any ideas?
Hello Justin. Let me know what your motor, transmission, harness and computer came from and I will see what I can come up with. The 5.3 with a 4l80 is not the usual configuration, so I would need a little more info. Jerry
@@UglyTruckExperience 5.3 from a 05 silverado setup to run with a 02 harness and computer, dbc, cam, card style maf, fast lsxrt intake, flex fuel injectors from 08+ silverado, circle d stall converter. Harness is a reworked stock harness setup for exactly what I have. I have tested all my wires and solenoids etc can't figure it out. Just bought hptuners last weekend truck was tuned by a rude shop that doesn't want to help and says its my problem to figure out. Been a year now testing all my wires and parts and throwing new parts at it to make sure nothing is bad/wrong with my stuff. I think its all in the tune...
I think you are probably correct about the tune. You have some mismatched parts all together and I would think the ECM is probably not set up for what you have. I would try pulling the wire from the S position on your transmission connector. Should be a brown wire. That is the wire that grounds the torque converter solenoid to engage its clutch. With that wire undone, it definitely should not lock up the converter. If it does not lock up with that wire disconnected, I would check that wire with a ohmmeter and see exactly when the ecm is grounding that circuit. If it has ground always, I would check for a short to ground with that wire unplugged from the ECM connector 2, position 2. If the ECM is grounding it when you hit around that 5 mph mark, It would be a problem with the tune. This is an interesting one. I don't get a notification when you comment back, so you may want to start a new comment so I can make sure to see it. Jerry
I was told I needed a brake switch added, by the transmission shop it’s a crammed ls1 4l60e in a 89 Silverado used to be the 350 tbi, do I need to add this setup to mine?
Depending on what your donor motor harness and ECM is. In this case a brake signal is not required for the torque converter to work. I talk about that a bit in the video. The ecm senses a few different things that will make the converter disengage. I have wired them with and without and really couldn't tell much difference. Thanks Chad. Let us know how it goes. Jerry
@@UglyTruckExperience my ls stuff is all out of a 01 trans am, I had the harness sent off to make into a standalone. I do have some codes so I will send it to the tuner next week! I just don’t wanna blow up the new teanny
If my tcc isn’t placed right will that cause brake lights/reverse to no function?

What relay did you unplug? When you drove it before, what kind of symptoms did the transmission have other than the code or check engine light?
@@UglyTruckExperience i’ve been driving it, but I know the TCC being able to engage helps with keeping the transmission cool and saving on fuel so I decided to finally go ahead and do it as to put less strain on my transmission and torque converter. I think the only other thing I’ve had before this, I can hear a slight wine when I accelerate but I believe that’s because I forgot to check on my fluids and I was excessively low on the transmission but other than that it’s shifts fine.
