What yoke do I need for my 4l80. Its goes from the splines to a gap then o-ring. The bolt on yoke thats on it is short. The trans is a 98. Its goin in my 94 c1500 behind a 5.3. I don't have away of cutting the yoke if its to long.

the strange u1664 should work. i have one in my car. the end of the yoke is counterbored, something i didnt know or need as my shaft is fully splined. i bought a mark williams yoke but the splines wouldnt fit so i bought that one.

Yea this is goin in my truck so I figure I should probably use a bolt on one.

Ok so I found that 4l60 thats I'm my truck now uses a slip yoke so I figure I otta get the same thing.

I had my output shaft machined down to fit a regular style yoke when I had it torn down for the rebuild. If you can't do that then you will have to get the counterbored one that everyone is talking about. The bolt on yoke is used in trucks with a different type of drive shaft

ok so everyone has different suggestions lol. since i need movement in my drive shaft the only place i can get that with my stock drive shaft is with the yoke. my 4l60 has a slip on yoke. so i kinda figure i gotta run a slip on since im using the stock drive shaft. the yoke thats on the 4l80 is a bolt on and its short. I believe a short slip yoke would be to short would it not? so should i get a long one and hope it works or get a short one and hope its long enough and wont fall out.

It doesn't matter if you get a long or short slip yoke with a bolt on style output shaft. The output shaft gets bigger past the splines so it won't let you slide it any farther
