A couple hours of being parked after running fine, I got in and shifted into Drive with nothing, manually shifted into 3rd with nothing, but manually shifting into 2nd,1st and reverse worked. Accelerating in either 1st or 2nd, the tranny would shake pretty bad with just a touch of the pedal. The car has 93k and the only signs of problems were every 2-3 months, I'd put it into Drive and it would take maybe a second to engage in 1st but no real problems what so ever. Any help would be much appreciated.
