Interchangeable A833 input shafts

66fs: No, I have not started with the dissambly yet. I will begin to order a basic rebuild kit and then see what other suprises there is ahead of me when teering in to the box.
I can of course take both trannys apart but if it would be obvious that the input shaft from the other box won´t fit i rather just leave it as it is for now.

Typically all new bearings, counter shaft, gaskets, seals, rear bushing, and small parts. I agree with AJ/FormS, keep the gear sets/housings together if you can. Carefully inspect the synchro assys and synchro teeth on the gears. Don't throw any parts away until you get it together and try it. Use 90 wt gear oil.
