#1 of 1 Jimmy won't shift by mmeuli Dec 10, 2007 (12:22 pm)
My 2000 Jimmy has been hesitating when I accelerate. It has gotten worse. Now it won't shift out of 2nd. Computer says to replace about 6 different things including ERG Valve and Mass Flow Sensor. Now that I have done those 2 things it runs better, but still does not shift out of 2nd. Read on here to change the Transmission Speed Sensor. That didn't work either. Now the service engine light has gone out and the computer doesn't tell whats wrong anymore. Anyone got any suggestions.
