1990 Buick Electra Park Avenue 6 Cyl 3.8L
Transmissions & Drivetrains
The parking pin will not disingage. I have to work the gear shift up and down to get in to release.
Sometimes it will go into low gear after working the lever up and down a few times then I can bring it up to engage into overdrive. Most of the time can't get it into reverse at all. It takes a lot of working the shift lever up and down.
Sounds like you it's time to rebuild your transmission. Try to use the Find a Shop feature of AutoMD ( http://www.automd.com/shops/) to see a list of shop near you with their address, telephone # and labor rate per hour. You can call a couple of them to compare opinions and prices within your area.
