Grim82- stock height 89 1500 suburban and seems like the yoke goes in far enough. I have read leaks caused by a plugged breather, weep hole in the yoke, bushing and the rear seal. After replacing the rear seal the leak got worse. Hate to take it to a tranny shop if I can figure out where its leaking and address it. Atf drips out and is thrown all over under rig. Frustrating.
