I loaned the car to my son for a couple of weeks, and when I got it back it wont shift out of second gear. I inherited this car from my Uncle who purchased it new. It is very low mileage, and never gave any indication that something was wrong (always shifted smoothly, etc). I spoke very briefly with a guy who also had a similar problem and said it was fixed pressing buttons on the air conditioning and radio. Any help would be greatly appreciated.
I had the same problem last week with my 1988. I took it to DIck at Allante' SOurce in West Palm Beach and he diagnosed it as a bad Transmission Position Sensor. He changed it right there and the problem was solved.
