Looking at different model E36 318is on realoem.com there seems to be quite a few different types of automatic transmissions available.
I have a 12/1996 318is (M44) which according to realoem.com has a A4S 310R "RO" type and I am looking for a replacement.
How important are those last two letters?
Will an auto trans from a 1995 318is (M42) fit? Or one from a later 1997 M44 that has a different two letter code?
Anyone know some way to look up the differences in these transmissions?
