Did you put on a new circlip when installing it?
If not you might expect some trouble down the road... happened to me! Guy that reinstalled my newly TH rebuilt tranny most likely didn't use a new one, or didn't seat it all the way. Shaft came out and was barely making contact... stripped the splines above the clip.
Not to mention that I added OVER 2 quarts of fluid to top it off again! Realize that totally empty the tranny holds less than 3 quarts!
So this is a potentially serious issue!
