While I was fixing my 4l-slippy I figured I might as well do my rear main seal. For is perfect. Have a slight leak, but I didn't change my pan gasket yet so I assume that is the cause especially since oil isn't gettng flung by the flex plate. Recommend doing the pan at the same time for others. Will update when I feel like doing the pan gasket.

I have been a technician with GM for 30 years and this seal leaks worse than the original one.

This picture shows the rear seal leak under my truck that I just put the motor in I put all new seals in it before I put it in. It's a big job to change it out not sure as to what I'm going to do now but I would NOT!! RECOMMEND THIS REPLACEMENT SEAL TO ANYONE..

Seal material is too rigid and does not flex. Leaked straight away.
