    My car will not drive in reverse or forward.. Could there be something else wrong other than the transmission?

      Has to be towed to a shop

      You could check all the vehicles fuses
      but i doubt that would resolve anything
      if one is blown

      Transmissions seldom work one day & not the next

      There is plenty of warning before they fail to move as yours is

      Check for fluid leaks & low fluid level

      Seldom a transmission lasts more than 15 years

    Why does my car hesitate in the middle of a gear change?
    Mileage- 57600; We have only owned the car a year. No former problems we are aware of. When the car goes into a gear change after taking off, it sometimes hesitates in the middle of the change a few to several seconds before the change goes through. It is not ...

      First question - have you checked the transmission fluid level, and refilled as necessary?

      The slipping shifts is a common problem on this model transmission. It is due to a failure of the forward sprag clutch. This clutch is fully mechanical and the transmission does have to come apart to replace the forward sprag clutch, but typically a full rebuild is not necessary. You can drive the vehicle with the transmission shifter in the Low 1 range then shift up manually to avoid the slip condition, as there is an additional hydraulic clutch applied over the forward sprag clutch when in the Low 1 range.

      There are other possibilities; pressure control solenoid failure - may cause erratic shifting.

      Could be a clogged and restricted catalytic converter. lack of fuel pressure, faulty MAF sensor. you didnt mention if the check engine light was on or flashing. whether or not the transmission was actually shifting. theres a lot of veritables, start with the basics and go from there. process of elimination. hopes this hopes. good luck.
