hey guys ever since i bought this car ive always noticed that when going 50-60mph going from 3-4-overdrive that the rpms would surge and kick it back into 3rd then it would repeat that process. the cars history states that the transmission was overhauled by ammco transmissions at 95,000 miles and it only has 139,000 on it now ive barely put any miles on it. i read on gtpworld forum that it could be a faulty brake switch sending a signal to the tcc to lock up when the brake pedal isnt even being touched, i was wondering which switch would it be on the brake pedal as i have one with 2 connectors and one with only 1 connector? thanks
