4l60E to 4L80E Swap Pt. 2 Driveshaft and Wiring

Glad it was helpful!

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

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

[@Bigpowerlowdollar]

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!

[@markrusso3784]

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

[@CREESE99]

@@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!

[@markrusso3784]

@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

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.

[@rolandgutierrez813]

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

[@urielcardenas5270]

What model and year did you get the 4l80e off of?

[@gunsandhorsepower]

How could i get a 4l80e to work in my 2500 with a nv3500

[@urielmireles5024]

Was the 4l80e a 2wd or 4wd ?

[@rlfdavin]

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...

[@FFMotorsports22]

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

[@jdeco1856]

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

what about rear gears ?

[@Pedritoe376]

Im currently swapping my rcsb silverado with a 4l80e i already got 4.11s in the rear what yall think

[@FFMotorsports22]

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 ?

[@LawrenceTolman]

On a 4wd the driveshaft lengths are different but on a 2wd all you have to do is change the yoke

[@FFMotorsports22]

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

[@brandonloll4262]

Hey LT what did you do about driveshaft length? Did you shorten it? Going one piece later? Great job!

[@LawrenceTolman]

Brandon Loll didn’t have to change length at all, just the different yoke

[@brandonloll4262]

Lawrence LT Tolman thanks, good to know!

[@Kiddo_Delano]

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.

[@FirstLast-we8cb]

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

[@a2cryss]

So was the original speed sensor in the 4l60 pinned internally to the trans plug and now it is a separate plug?

[@LawrenceTolman]

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

[@spencerbowyer4868]

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?

[@torchwork8651]

[@evanmalinowski6302]

[@yayaya1193able]

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

[@guitargod66]

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?

[@LawrenceTolman]

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.

[@guitargod66]

@@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.

[@207shenanigans]

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?

[@brandoncharley3070]

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?

[@LawrenceTolman]

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
