4L60E to 4L80E EASY Driveshaft CONVERSION 

This helps out a lot, thanks!

That's awesome brotha👏

Well you helped me out brother. I have a whole donor truck and as soon as i pulled the yoke out of the t case on the 2500 i put a glove on it to protect it never looked at it. I was under the assumption it was bigger and wasn't compatible. I just went out there and pulled the glove off and what do you know, same thing smaller u joint. I was looking all over the Internet trying to find a conversion joint for using the 2500 shaft on the 10 bolt rear. (I'm not ready to swap axles yet the 10 bolt has 513 gears. I'm already hemorrhaging enough money just getting this 4l80 in there without swapping axles the truck has been sitting since 2012 when i blew up the Monster "HD 4L60E" after 5k miles... so i want to drive it and iron out the problems I'll have from it sitting before i deal with the problems troubleshooting the solid able swap Dana 60. I'm hoping doing one thing at a time will make it more tolerable) I'm thinking because the truck is lifted 9"my 1500 driveshaft should work fine since this one did on a stock height truck. Thank you! That was one of the bigger worries i was having.

The 4wd Chevy s10 from 91 has the small u joint and the 32 spline

Great discovery! I wonder if this trick works for 4th Gen LS1 Camaros and their aluminum drive shafts.

This is great I’m doing a 4l80 swap on a ecsb truck so I’m hoping this will work with the 2 piece driveshaft setup Edit on 12/23/2023: I finally put the 4l80 in my extended cab and I don’t need to use one out of a 4x4 1500. Depending on what your 4l80 came out of you may need it but the carrier bearing mount holes are slotted so the carrier bearing can be move forward/ backwards to make it fit

A shaft center of ujoint center of ujoint would be very helpful

Thank you for the vid appreciate the breakdown Do you think This application would work not only on 4l60 to 4l80 swap on a rcsb but also 4.3 to 6.0 swap asking cause idk if the flywheel , or motor mounts makes a difference in the measurements

What was the difference in length between the two yokes? I'm trying to make a 4l80e swap easier down the road without needing a new driveshaft.

I have a 2003 Sierra work truck with a fleet side 6'8" long bed. I want to remove the 4L60E (23.5" length) transmission and replace it with the 4L80E (26.4") length transmission. The math seems to say I need a 32 spline yoke that slides into the rear of the 4L80E transmission that is shorter by approximately 2.9". My main issue is that I have not pulled the driveshaft off yet so I cannot share the yoke parameters currently on the truck. But I'm not really sure that would be very meaningful as the current 4L60E transmission is being replaced anyway.

Have a 07 yukon 5.3 w the afm & 4l60 . Did a swap from my 07 escalade 6.2 w 6l80 switched engine harness & ecu everything works like butter but ujoints are a tad bigger to go in rear differential. Cant find any info besides getting driveshaft modified or swapping the differential. Hopefully i can find a set of u-joints like the one you mentioned

i have a ext cab that i did a 6.0/4l80 swap i used the same driveshaft and used a shorted 4l80e yoke i bought the moon 447 off summit racing when i installed the u joint to the yoke it has a play to it like it moves side to side. when the u joint is on the drive shaft it’s perfect no movement or nothing but in the yoke i can move side to side like it has a gap of a 1 or so on each side of u joint

by doing this you can use the factory truck driveshaft? you won't have to use a custom driveshaft or anything like that correct? And great vids man!!

Awesome vid, in the middle of the same swap now. Do you have a part number for the rear output shaft?

Hey doing a swap What’s type of crossmember is it custom or a 4x4 1500 crossmember and does it have to be for a single cab

I have a 2000 2wd with 4l60e im swaping to 4l80e 2wd its a reg cab shortbox lowered 4/6 So the 4x4 i pull the yoke out of does it need to be a 4l80e 4x4 or 4l60e 4x4 thanks

Is the 4x4 1500 yoke the same as the 2500 yoke also

Is that yoke counterbored? I’ve been trying to find out if it is or not but I’m not having any luck. Also which output shaft do you have? Mine has about 2.75” of spline and then an o-ring, it was originally a fixed yoke. Any info you can provide would be great! Thanks!

I have a 94 tbi 4l60e 2 door swapping 5.7 &4l80e would my drive shaft work ?

What is the number for the moog joint ???

So a 2001 all wheel drive suburban yolk work?

Will this work if your truck has a 3" 5" drop?

so all i need is my 4l60e shorter yoke and that u joint and the cross member and ill be set?i have a 2000 silverado rclb btw

Could you clarify? Do I need a rear yolk from a 2000-2006 4x4 4L80E?

4l80e swap in my 99 c1500 burb. The joints are the same as the 1ton I pulled it from. Would the 4wd slide yoke work without having to get the conversion joint?

Do you happen to have part number to that yoke? I go to local junk yards and all they say is no we don't have it. They're too lazy to go check

Did you have to balance drive line because yoke is not the same will it cause wobble ?

Do you have the part number on the 4x4 yoke ?

I have the 447 ujoint and the Dorman 697-502 yoke but the ujoint won’t slip into the yoke and the caps are too big to even go into the yoke. Could I sand it down to make it fit ? Or any thoughts?

What about for an extended cab truck with a 2 peice drive shaft with a carrier bearing?

Part number to slip yoke ??

Shorten yolk part number?

Do you know what the wheelbase on that truck is

What if I’m swapping into a 4wd not 2wd?

So if I do the yolk swap I don’t need to send the drive shaft to get cut?

Hey Jason do u have the link to the crossmember?

I have a 95 Yukon 4x4. Would this method still apply?

Has anyone confirmed the 4x4 s10 will work?

HELLO.. SO I HAVE A 2003 TAHOE 4.8 4L60 CAN I MAKE THIS WORK?? THANK YOU..

This video dosnt specify. But I believe this only works for 4wd vehicles. If you have a 2wd vehicle your going to need to have driveline work done. You can't make less with more. So you will have to shorten the driveline at a shop,or at home if you don't mind vibration, to make the stuff fit.

So would this work with the 4l80 swap with a 4/6 drop?
