4l60E to 4L80E Swap Pt. 2 Driveshaft and Wiring
ฝัง
- เผยแพร่เมื่อ 26 ส.ค. 2024
- In the last upload, I physically mounted the 4l80e to the 5.3 LS using the flat 6.0 flexplate and crankshaft spacer, and then modified the crossmember to hold up the transmission since the rear mount is in a different place. This time, I'll go over the last steps to connect the 4l80e to the driveshaft and get the wiring sorted out. This requires swapping a yoke for the 4l80e onto the driveshaft that the 4l60 was attached to, and a wiring harness adapter for the 4l80 that will allow the electronic connections to be made and the input speed sensor to be connected to the computer, and lastly, you will need to segment swap the computer to allow the 4l80e to be properly controller.

Hey what did you use for shifter cable bracket
Love these videos I own a 99 Silverado that's my project truck and I've always wanted to swap my 4l60 to a 4l80
Thanks for watching! If you’re planning on any serious power upgrades, it’s almost a necessity
@@LawrenceTolman what crossmember can I use on my 2000? I tried the speed engineering 4l80 crossmember but it doesn’t work might have to modify the original
@@jasonloera3358 2WD or 4WD?
@@diduck6878 2wd. I had to fabricate my stock one. I guess early 99- early 2000’s truck have a different kind of crossmember compared to late 2000’s-2002 I ended up returning the speed engineering crossmember
It was a little difficult to find a video that explains what the yokes are, thanks!
Glad it was helpful!
Im working on a L31 vortec wiring harness for a project of mine and the transmission connector was meant for a 4L60E so what I did was I pulled two wires from the connector and used them for the second VSS sensor and then moved two wires at the PCM. pretty simple and cheap option
Love it. I’m doing this exact swap. With the two piece driveline. On my second blown 4l60e. Finally gonna swap to a built 80e. Thanks for the simple video!
Do you have to cut the slip yolk when using the oem 2 peice driveshaft? I'm doing this swap on my 2001 gmc sierra 1500 crew cab also. Not sure if I need the long yolk or short one
@@markrusso3784 Have you done the swap yet? And if so what did you end up needing to do? I am going to be needing to do this same swap in the future on my 2001 Silverado 1500 crew cab short bed 4x4 as my reverse has decided to give up the ghost. Thank you!
@CREESE99 just got done with it and ended up having to shorten my front driveshaft slightly to make it work, unfortunately changing the yoke only wouldn't work my driveshaft shop told me
I love the horsepower TV vibes!
You are an excellent speaker.
Thank you!
Moving right along. Looking good!
I have an 08 avalanche with a 4l60e, I’m trying to do the 4l80e swap but I’m having difficulty figuring out what pins to use on my Ecm for the input speed sensor. it’s the later style Ecm not like the red/green and blue Ecm. Idk if I’m just slow but if anyone could help I’d really appreciate it.
Im working on a 4l80 swap at the moment same set up i got a 05 cateye 5.3 paid 400 for the 80 trans
TVIcelink wish I could’ve found one for that much. They were all like $800 and up around me
I live in Las Vegas nv it was a offer up sale i went to look at a 06 gmc 2500 running & driving are you planning to throw a bigger converter in the future?
how much is it costing you to built it or have it installed ?
What year 4L80Es are good for doing this swap? I know they can't all "be the same." I'm actually going to do a 5.3 with a 4L80e into a 95 Chevy 1500.
Great vid LT! Keep it up!
Joey Jakubiak thanks for watching!!
Awesome video! just got a 4L80E with flex plate is the 4 parts you listed from Amazon all I need ! Thanks
I have to do the samething man great 👍 video!!!
Would this be the same for a 4x4?
AWESOME! Keep it up buddy!
For the wiring I’ve been told I can swap the harness from the 2500 onto my 5.3 instead of buying the jumper harness how true is that and would I still have to retune the pcm for the 5.3 or would it just be plug and play at that point ? 4x4 truck by the way
The 2wd swap is sooo much easier. I built a 4l80 and swapped into an 02 Yukon. Custom driveshafts, modded xfer case, and so forth. Hptuners was the easy part. Good vid. Also note that the newer 4l80 have trans lines both up front like a 4l60. Big warning for you is if you do an lines, there is a special extended fitting for the rear line. You'll kill the trans if you don't have that. My old Yukon before it was destroyed when a cop rear ended me. i.imgur.com/CHPxj5g.jpg
Do you have the link to the right yoke ? the one in the description doesn’t work @Lawrencetolman
How could i get a 4l80e to work in my 2500 with a nv3500
what about rear gears ?
What model and year did you get the 4l80e off of?
Hi LT , great video , very detailed too , thanks , i am going to work on upgrading my 2003 ext,cab siverado , has a 4.8 , going to drop a 6.2 and replace the 4L60E with a 4L80E , i am thinking that i will need to replace the drive shaft also because the 4L80E is longer than the 4L60E ? any other pointers ?? thanks
Do you think the same u joint and yoke will work for my 2wd suburban? I'm going from. 60 to 80 and I'm seeing a lot of people using same driveshaft but the special u joint and yoke to help make up the shortened distance needed without modding the driveshaft itself...
Thanks for the video I'm looking for a adapter green plug 2 Brown plug early 4,l65 to late model 4L65 can anybody send me information on adapter thanks
Could you send the link for the yolk and U joint that you used currently trying to gather everything up , thanks for the informative video
Sure thing...

Was the 4l80e a 2wd or 4wd ?
Hey LT what did you do about driveshaft length? Did you shorten it? Going one piece later? Great job!
Brandon Loll didn’t have to change length at all, just the different yoke
Lawrence LT Tolman thanks, good to know!
So was the original speed sensor in the 4l60 pinned internally to the trans plug and now it is a separate plug?
no, the 4L60 has one external speed sensor, but the 4l80e has two, one input and out output. plus the pins inside the main trans connector are in different spots
i am doing the exact same swap- 4l60-4l80. i have the original steel driveshaft and i have the driveshaft that matches the 4l80. i got both the 447 and the 290 Moog u-joints, but they are short on the cross section & caps for the slip yoke side- almost a 1/2" of space from the spring clip to the top of the cap. did you run into this?

So I’m doing a 6.0/4l80e swap in my 06 crew cab do I need to shorten my one piece driveshaft or shorten the yolk ?
I’m doing a swap with my 04 GMC Sierra 2 wheel drive 4.8 to a 6.0. I already have a low mile 6.0 from a Chevy van with a ecu. My question is, can I use the ecu that came with the van even though my truck has a 4l60e and the van had the 80e? Or will I need a re flash?
So the dust cover that comes factory you don't need?
Evan Malinowski you should have one on there, I just hadn’t cleaned mine up and installed it then.
Stock driveshaft length worked? I might do this on my 2wd suburban which may be slightly different lengths
What's the name of that u joint to adapt that yoke from 4l80 yoke to 4l60 drive shaft
What did you do about the rear cooler line fitting into the trans? I have been researching and building my parts list for this swap and the longer rear fitting(protrudes deeper into the 4L80E) is something that a bunch of people say has killed transmissions when overlooked. Did your 80e have one you were able to reuse?
yeah, the stock "c-clip quick connect" fitting was still in the trans when I got it, so no need to do anything. but yes, if you are swapping an aftermarket AN style fitting, you do need the longer fitting in the rear port
@@LawrenceTolman oh cool thanks. I had read about people extending the stock line, but their descriptions always sounded hack, yours is the first I've actually seen and it is so clean and cheap that I will probably go your route.
So what you’re saying it I don’t have to get the driveshaft cut… I can change out the slip yoke to a 32 spline and run the 4l80e transmission and transfer case with the original 4l60 drive shaft ?
On a 4wd the driveshaft lengths are different but on a 2wd all you have to do is change the yoke
Thank you for this fast response on a video that was posted 4 years ago because I’m in the process of buying a 4l80 right now and needed this information
You didn't need to cut anything off of that 80e slip yoke? it looked like it bottomed out when you pushed it into the transmission. Since this is a 2 piece, do you not need that inch or so of play when the driveshaft is installed?
LS Graveyard I made a mark with a sharpie with the yoke all bottomed out, and in the final position of the driveshaft it had about 3/4” of free play, no trimming of any kind.
@@LawrenceTolman Ahhh ok gotcha. That is awesome that this part was basically a full bolt over conversion. Thanks for making this vid. Man I just spent way too many hours on the forums, which continues to prove a giant waste of time. Watching your vid answered a lot of questions that I had. Is there any way to verify when you are 80e shopping, that you have the transmission which has a fully splined output shaft? Some of these apparently have splines a few inches up, then there is come kind of collar deal around it. I'd imagine that the ideal one is one with all of the splines.
How long was the yoke 7 or 5 inches
Could you replace a half ton 6-speed with a 3/4 ton 6-speed and a 2014 Silverado
I have seen a few people do it, but not sure on the specifics
Yes
The differences are not physical or electric. It's a couple of clutches inside.
@@diduck6878 thank you
@@LawrenceTolman thank you LT
What no 2nd gear burnout in the garage?
Josh Brake lol, didn’t wanna full the shop with smoke
How do I know which cooler line I have to extend?
Did your driveshaft have to be shortened
What's the u joint part number and did you use the stock 4l60e trans shifter?
Put the amazon link
Hi, question ? What about the " driveshaft " it self ? Did have to shorten it? Thankyou
no, its the same exact length as before
@@LawrenceTolman how does that work if the transmission sits 5-6 inches deeper towards the rear of the truck?
@@billstevens720 the mount is 6 " deeper. 2Piece drivshaft, and slip yoke
Can you please tell me how you got the 4l60 dip stick tube to work because it won’t fit
I used the 4l80 dip stick
very helpful, straight to the point video... im looking to do this swap in my 01 Suburban 1500. i tow a boat all summer and it eats 4L60E's every 40,000 miles so this is a must. how did your ECU flash go?
very simple to flash it, used HP Tuners and just did a segment swap with a 4l80e truck
@@LawrenceTolman i've got a local guy who did a tune on the vehicle in question... he's probably got the program for this.
Hey lt what happened to that white ext cab Chevy you guys turbo and 80e swapped on the show?
yayaya1193able that was mine, I drove it for a year or so, and then sold it to a guy in Kentucky
Lawrence LT Tolman thank you for the reply. Do you think he might be interested in selling it? Or is there a way I could get in contact with him? TY
Hey LT, I have a 2000 gmc sierra extended cab I want to put a 4l80e in, did you have to shorten your driveline or was your factory 4l60e driveline fine the way it was?
nope, on a 2wd the stock driveshaft worked perfectly with just swapping the slip yoke
What yoke you use
Part number please
Did the shift cable from the 4l60e bolt right up to thr 4l80e
Yes the cable works but you need an 80e bracket
@@LawrenceTolman thanks for the fast reply. My donor trans should have that on it.
hey it says that the slip yoke you used its not avaliable anymore, do you know of any other slip yoke that would work?
Budget builds what did you figure out?
Which engine do you have?
at the time of this video, it had the 5.3, but it has since been swapped to a 5.3
Wassup man quick question I wanted to swap a 4l60 into my 5.3 it has headers and is tuned but I heard the 4l80 will need more power to spin the tires and I didn’t want to not be able to do donuts
If your truck has torque, should be no prob
Having an issue finding the slip yoke, The amazon link says no longer available...
I've ran into this problem as well and i tried to order it thru southwest speed and they said they are out of the product. Im at a stand still.
@@stephenbracey6973 I found a solution. Get a slipyoke from a 1999-2005 chevy silverado 1500 4x4. the slipyoke that goes into the transfer case is a 31 spline.
The 4L80 I purchased already has the yoke in it. What U- joint do you recommend
they say the ones without the grease zerk drilled out are stronger if you're going for a high power application, usually MOOG is a good brand
Do you have to re tune the ecm
yes, I used HP Tuners to do a segment swap for the 4L80e, then adjusted the shift points to my liking with the 3.42 gears it had at the time
@@LawrenceTolman sweet do you do any mechanical work to the public I’d gladly bring my truck and let you tune and help whatever the price
Where did you get the extension for the speed sensor
amazon
Did you have to change starter ?
nope, the original starter still works
@@LawrenceTolman thanks!
I still don’t understand how you got away with the same drive shaft I would love to throw one in my single cab but don’t really feel like choking up the money for a custom drive shaft isn’t the 4l80e six ish inches longer ?
2 piece driveshaft
6" difference in mounting
Part number for the u join
Was this 4L80 originally a slip yoke transmission?
yes it was
Man that 5.3 has a serious oil leak somewhere
What shift kit did you get for the 80
Transgo HD2, although I didn't put it in until about a year after this video was made.
@@LawrenceTolman Awesome, that's the one I'm looking at. How is it?
How did you get speedo to work
once I did the wiring and segment swap outlined in the video, it just works
@@LawrenceTolman thanks
Goodness the way he talks on the TV show is the same as here 🤦♂️
