Here goes question #2 for tonight. I want to replace the rear trans. housing seal. The one that is supposed to fit is very different from the original seal. The rubber on the original seal protrudes about 1 1/2 inches...on the new seal, it only comes out a bit. Probably does not make much of a difference but I would like to make sure before I do the work....hate to do things twice (or more!). Can anyone help?
