The transmission will down shift from overdrive to drive after you’ve driven it for about 30 min. It has about 150k on it.

You can see the rpm guage change when it does. Help before I spend a lots.1995 ultra Park Ave. Buick

When was the last time you had the transmission fluid changed (not flushed)?

You should be getting the third or forth one now. If you have not had it done… I don’t know if I would suggest trying and hoping for the best or not. I think I would give it a try.

Note: hang on for a while. If Transman shows up, follow his advice. It is THE MAN when it comes to transmissions.
