If it is the same problem I had, it is in the transmission and requires the pulling of the transmission. This is a comman problem with some Montanas. It might be the pressure control solenoid located inside the valve body of the transmission. Yes this is probly your answer. These cars have this problem alot. I work for Gm and I know first hand. I was having the exact same problem two weeks ago. I replaced the pressure control soleniod and the transmission now shifts as smooth as it did brand new.

Either way it should be replaced as it will fail and saves on prper fuel milage and running of engine. It fastens to the throttle body by 2 bolts and is a common fix.
