My 2000 bravada will not shift into reverse or overdrive, and shifts hard from 1-2 gear. It won't shift from 1st to 2nd until about 3400 rpm. I have replaced the filter and fluid, which made the "service awd" light go out, but the shifting problem remains. I am thinking that it may be the control solenoid, but I am not sure where to find it. Any other ideas or tech data would be appreciated.
Where is the transmission control solenoid located? on 2000 Oldsmobile Bravada
they are in the valve body on the side of the trans but i doubt that is your issue. you have an internal failure. let a trans shop test it for you and give you a pinpoint failure and a bid.
