    I never have, and doubt its necessary since it will be bathed in ATF all the time anyway as long as the level in the case is as it should be.

    i put a little bearing grease on the slip part of mine. it helps keep it from binding up.

    I like to grease the pan just a bit before I slip the yolks in... /forums/images/graemlins/wink.gif

    As for those slip yokes, I think GM has a special grease that you can use on the splines that will help prevent binding. /forums/images/graemlins/cool.gif Twizted is a GM tech, drop him a PM and he might be able to get ya a part number. /forums/images/graemlins/thumb.gif

    When I replaced the output seal on my 208, I filled the recess between the inner & outer lips of the seal with grease, and I put a light coating of grease on the outside of the slipyoke shaft. I also put a little ATF on the splines inside the shaft (used a small paintbrush) to keep things smooth. Worked great, no leaks nearly 2 years later.
