I know this is the wrong place to ask, but I couldn't find any Buick groups..
Many thanks in advance to anyone who can help tho...
86 Buick Grand National GNX
60,000 miles, some performance parts, nothing done to tranny tho. reg.
maintenance. Got it in 1990 with 15K on it.
I changed the tranny fluid+filter last week as I don't think it had ever been
done or atleast I've never done it. the old fluid+filter didn't look bad but at
60k i felt it was time to be done. Topped it off to the correct levels and used
correct fluid to mfgr specs and I didn't touch anything else when i had the pan
off. Anyway, I took it out on a test drive and all is good. shifted firmer etc
so I came home, put it in reverse to back into the drive way and it jerked and
then it was like it was in neutral. So it seems reverse is completely gone.
Drive, 1, 2 etc are all fine. still shifts wonderfully but reverse is gone. what
could've happened? possibly a pre existing problem? thanks again.
