Measuring crank to bell housing alignment A904

First off your tranny has to be gutted. Then u will need a dial indicator and magnetic base. Kim

Another crucial alignment check that is often overlooked, especially on 4 speed set-ups, is to verify that the mating surface to transmission face is square to the crank centerline. I can't visualize how you would check that on an automatic. My '70 E-Body with RB has a scatter-shield that was significantly off, and required shims to get the bellhousing square.
