Would a A4S 310R Auto Transmission work.
I might be getting a 2000 323i Wagon for $3000 and all that is wrong with it is a bad Transmission. I have an extra A4S 310R Auto Transmission that i have out of a auto 1991. Its 525ileft over from my 24v E30 swap. I know that it will bolt to the block just fine. What i'm not sure of is if the electronics are different, and the lenghth of the transmission if the drive shaft will work. Has anyone tried swaping in an older trasmission?
