Tranny Seal

The trans tailshaft seal. No, it is not difficult to replace. But if all you ever done to your car before are oil changes, bulbs..etc..small stuff...then this might be a little difficult. The seal they are referring to is the tailshaft seal where the driveshaft is attached to the transmission. The driveshaft has to come off in order to replace the seal. Also, the trans fluid will have to be drained before you remove the driveshaft from the trans otherwise you'll have a big mess of fluid spilling out the tailshaft...You should go and pick up a Haynes or Chiltons manual for 94-04 Mustangs. One of those manuals will greatly assist you. They have step by step instructions with pics on how to fix most things on your car.
