Sounds like your trans is slipping. These transmissions are very weak and alot of us have problems with them. If you dont wanna blow your trans you should probably not do it anymore.

When is the last time your transmission was serviced and how many miles does the car have?

Pan should be dropped and filter should be changed then filled back up with fluid every 30k miles.

There isnt much you can do at this point except dont beat your car. We here on the forum like to refer to these transmissions as being made of glass. Be happy yours made it over 90k miles.

Also if you rebuild or get a new trans a external trans cooler off a police impala will help prolong its life.

Also if your still under 100k you might still be under the drive train warranty you might want to take it to. a dealership
