Well I have a ahnd me down Grand Prix Se 1988 I'm assuming I'm in the correct area to post this - The transmission is an automatic -has first second drive and overdrive. Hers the deal the transmission will not go past second gear I believe. In drive I can only do 45 mph and Im up to almost 4 grand on the tach. I really dont know where to start to fix this - I really dont drive the car far about a mile a day to work -but i would like it to work proper. Does anyone have any tips that might point me in the correct direction to diagnose this problem-Also I'm not ready to to go to the tranny shop -its just not worth it to me. What are some of the things i should check besides the transmission fluid? Thanks any tips would be greatly appreciated
