Thanks guys. Got the old seal and bushing out. Now to see if I can find all the needle bearings.
While I got your attention, I've read a bunch of posts about GL4 vs GL5 tranny fluid.. GL4 good, GL5 bad.
What about GL3 ?? Local supplier has Pennzoil Synchromesh GL3. An oil type I haven't seen any posts about.
GM part 12345349 or 12345577, spec 9985648
