Recently acquired 92 735 IL will not shift out of 3rd when in Drive. Car has 114K miles is in fair condition and don't know of it's history. A repair shop recommended a new transmission for $2,400, I would think is could be repaired but what do I know ! Will be greatful for any help. Bedford

have you checked to see if the trans is stuck in sport mode?
sport mode will lock out fourth gear.
