won't go in reverse....only forward
Sounds like you need to replace the gears or the transmission, both of which are not an easy task meaning if you are not a very experienced mechanic it's time to take it to a mechanic. I had to have the tranny in my 98 jeep replaced for the same reason.
start with a check of your shifter alignment. As the vehicle ages, this becomes likely and this is where you start your troubleshooting. If not this, see the "replace gears or transmission" advice.
Okay...gears have nothing to do with this. Shifter linkage could...but probably not. I'd say that your reverse is shot in your trans.
