I remember seeing something about having to replace the output shaft or have a custom tailhousing made....anyone ever done serious research and figured out what needs to be done to mate a T56 to a transfer case?

 

nm did a search, doesn't look like there's any solution that wouldn't cost an arm and a leg.

 

it sure would be nice if it didnt cost an arm and an ******* wouldnt it?

manual > auto... maybe in the GMT-900s they'll have a decent 6-speed that mates to a x-case.

 

yeah if i had a few grand to throw at it maybe i could figure something out....ill keep hoping that they come out with something decent that's x-fer case compatible.

 

Why is it so hard? A custom output shaft, an adaptor plate or something and 2 driveshafts? Right?

 

Custom output shaft screams $$$$ to me. Are they real expensive?

 

I know the HD's have the option for 6 spds, did you try looking donw that route?

 

Not yet....I need to figure out exactly what is wrong I guess before I decide what route to go. I can either do a 4L65E, have the 4L60E rebuilt again, or try for the 6 speed swap. Anyone have any info on the T56 vs the 6-speed from the HD's? Are they the same size? I looked into the 80E swap at one time and just the supporting hardware was almost as expensive as the tranny itself, I'd like to find something that is a direct or near-direct swap.

 

performance wise the 6-speed they make for our trucks sucks. 1st gear is a super low gear making it pretty much useless. And on top of that I dont think its a very strong transmission

 

Thunder in an 80e all you need to do is put a shift kit in it and it will be fine for what you do. Im only going to do a shift kti and clutches in mine ot put behind the new motor.
