I have a 1995 pontiac formula firebird lt1 v8 automatic the trans shifts fine and pulls good but it dont want to go into over drive unless you throttle it but as soon as you let off gas it will jump out of over drive to like its in nutrel but when you give it gas it will rev up till it catches up to the drive gear but it pulls great in all the gears does not slip what could be my problem oh and my motor has a little vibration at a certian rpm form like 2000 to like 25 2600 dont know what to do or check any input would help so much thanks

You need to take this to a trans guy to diagnose. He can see if there are any electrical issues with it. But with the mileage, don't be surprised if he tells you its overhaul time. It actually sounds like your lockup clutch is slipping in the torque converter.

That's why you need to take it to a trans shop as it could be a solonoid or an electrical problem that is causign this. It may not be that much to fix. They can run a code check on it to find out.
