SKF parts Info
SKF also has a site for finding the SKF part numbers. While on the SKF site I found a nice tool, with your VIN or car data you can find all the SKF part numbers used in your car. So I searched for a 1989 E32 750 and got all the details what I need for the 4HP24 repair in case I have a leaking shaft seal:
front seal auto trans oil pump seal 15803
front auto trans seal kit 15957
rear auto trans seal 15750
rear auto trans repair sleeve 99157 (that is the speedi sleeve)
