How do I fix my overdrive in my 2002 pontiac GP 3.8

Asked by Mar 23, 2017 at 05:00 PM about the 2002 Pontiac Grand Prix GT

Question type: Maintenance & Repair

My trans wont shift into overdrive. Anyone have any suggestions.

1 Answer


So either the overdrive is shot or the solenoid is not activating the overdrive gear. Have you checked for any transmission codes? That might be the first thing to do, if no luck there then take it too a good tranny shop so they can plug in and run the series of tests on the tranny and TCM.
