Shift Solenoid on 1997 Toyota Camry

The problem with my 1997 Toyota Camry is that when i accelerate, it takes a while to pick up speed even if i press on the gas pedal all the way down. On the interstate once it picks up speed it runs about 60 to 70mph but looses onces going up a hill. Sometimes when i stop on a light the rpm goes from 2000 to 1000 up n down then it turns off, my brother thinks it might be the shift solenoid, I would appreciate it if you could help me find out if it is the shift solenoid that needs to be replaced, thanks

When accelerating do you actually feel the car shift ? From 1st to 2nd, 2nd to 3rd, 3rd to 4th, and finally it should almost feel like, or maybe you only notice another RPM drop of about 500 RPM when the torque converter locks up. If you feel or hear these shifts it is probably not a shift solenoid. Now when you are decelerating to a stop and the cars RPM just steadily goes down with the cars speed until the cars stops and stalls it might be the torque converter lock up solenoid not un-locking. You should go to an independent Transmission shop (Not AAmco,Cottmans or any of the chain shops) and see what they have to say.
