Hi, I have a 325I E30 which the one of the past owners had the transmission converted from a manual to an automatic. Any way to determine if the original diff. ring-and-pinion ratio of 3.73:1 meant for a manual has been changed to 4.10:1 to suit the auto. transmission via visual inspection? Where do I look for it?
