4l80e has the bolt-on yoke. my driveshaft has the slip on yoke
 

Hey guys another question. All the 80e I have had were slip on yokes. So the replacement I purchased due to its mint condition came with a BOLT ON Yoke. Do I just unbolt that yoke and slip my slip yoke on, or will it damage the trans or leak?

I was thinking the worst case scenario, unbolt the yoke, and just swap yokes on my driveshaft? That maybe my cheapest option with a new U-joint from NAPA.

generally bolt on yokes are for vehicles that have IRS. that way the differential stays in one spot and the drive line distance doesnt change. the slip yokes account for the whole axle moving up and down and slight changes in distance. i would change it out for a slip yoke personally. i had to change the t56 i got out of a cts-v from a flange yoke to a slip yoke and that required changing the output shaft. what vehicle was your 80e meant for?

i thought you could just use the long TH400 yoke and cut it to legnth?

Mine was a bolt in yoke I just used a slip yoke..

Unbolt the yoke, if I recall all 80e 2wd output shafts have the provision for a bolt on yoke.

Is this infact correct? I can just unbolt the yoke and slide my slip yoke on it? If so wonderfull

Unbolt it and find out. You will know for sure as soon as you do.

Thanks Hog

Well I unbolted it and it has splines all the way I can see. So can I used my slip yoke? The bolt on yoke has a tapered end on the inside of it. But not sure if I will be okay

why dont you take your drive shaft and see if the yoke will go on?
