Driveshaft Compatability
 

Does anyone know if the driveshaft from the W58 tranny will work with the R154 tranny. IM doin a swap and I need to know if I have to swap over the drive shafts and the diff as well

im not sure if this will help, but i just did a swap with the automatic trans to the R154 trans off of my turbo parts car to my daily driver n/a car. the drive shaft was about 3 inches shorter on the 154 tranny. the only thing that i had to change was the intermediat shaft, which is the first half of the drive shaft with the yoke that goes into the transmission. then the shaft fit correctly. make sure that the bell housing will match up as well, with the swap that i did, the mounts from the engine to the bell housing were a little different so that two of the bolts would not have lined up. the diff should be fine, but, considering that your car has the lesser tranny, you probably have the open diff, the turbo car, which the 154 probably came off of, has a limited slip diff. Up to you, but i perfer the limited slip. good luck!

well i took the turbo tranny over with the turbo engine and now it's sitting in the n/a car. so your saying the driveshaft from the turbo car , which has the lsd, should come over to the n/a car with engine and tranny?

thnx.......

to be safe, i would, the shaft from the smaller one may be too long. i would just bring over the whole drivetrain if you have it. shouldnt be too much extra work.
