Expo auto awd differences?

[90tsiPA]

I'm assembling the parts To swap my car to auto. I'm acquiring a w4a33 trans this weekend but I came across a 2.4 expo AWD in a yard today with a w4a32. Question is can I grab this tcase and rear diff and use it for anything?

IIRC The a32 auto trans are very, very weak. They weren't meant for use with the power of a turbo car, and will slip majorly with any kind of power put through them.

Yeah I don't want the trans just wondering if I could use the tcase and the ring/pinion to swap in to my rear

So long as the Expo is a pre-'95 model -- more specifically, built before August of 1994, the transfer case will be a 23-spline unit exactly the same as the 1G DSM 23-spline units.

Sweet thanks! I'll have to take a closer look. From the information I found that rear is going to be manual dsm ratio. Does that sound right

Went back and looked at the car. It's actually a summit which doesn't really matter but it's a 95 and the rear cover says 3.307 and it has 3 bolt axles. So If I get that diff can I swap the ring and pinion into my LSD 4 bolt dsm rear or do they use a different gear set? I'm going to pick up a 91 dsm trans and tcase this weekend so the last snag is the rear.

That ring and pinion would be the same as the 1G auto ring and pinion. Shouldn't have any problems.
