UPDATE: I made sure the fluids were full and ran it for about 60 miles and still no luck with the reverse. I have all forward gears but no reverse. I called a local transmission place and he said it could be a "reverse servo" that is located underneath at the rear passenger side of the car. Can anyone help on what this actually looks like and exactly where its found?

thanks

 

The reverse servo is in the transmission. And, yes.....the reverse and low forward share the same band, so that doesn't seem to be the problem. That band can be adjusted from outside the tranny, but again, that doesn't sound like the problem. Again, I suggest you take it to a tranny shop and have it analyzed.
