I am in the process of searching for a transmission for my 1991 M5, my question is, what are the main differences between these 2 transmissions? is the gearing the same? would the 535i transmission bolt onto the M5? would this be a reasonable thing to do?
Also, how does the E34 M5 transmission compare to the E28 M5 transmission? I understand that the E28 has brass synchros instead of moly coated steel ones... would this be better then the E34 M5 transmission as far as reliability?
