New to the list. Hope I get this in the right forum. I would like to know how much difference there is in the transmissions between a 1989 420SEL and a 85 500SEL? Been a few years since I've had a Benz and not even sure what the body designations are for each of the vehicles. Also a fuse panel and relay layout for the '89 420SEL would be helpful.

Thanks, Karl M.
