...I'm not a tranny guy at all but this thread has a ton of info..
..I just asked for the best replacement part I could find and put it in, "re-staked" it as shown in an earlier post, and that was about it..The old "new" seal was already showing heat wear signs
..Pretty simple repair in hindsight considering where it's located...It's been a couple years now and without romping on it, I haven't had an issue since..Hope yours goes as easy..:biggthump
