The shaft for that gear and the rear syncro have been damamged and are metal floating around in your trnamsission just waiting to do dage. Before you do catasrphic damamge, take it to a transmission specialist and see if it can be fixed without a full re-build. I do believe you will need to go ahead and re-build the entire tranmsission though.

Could be a problem with one of the solenoids in the valve body. Possibly stuck / not allowing activation of reverse.
Transmission shop should be able to diagnose for you.

Sorry, my bad. Thought it was an auto tranny. LOL

Thanks guys, this is an automatic trans sorry I did not state this earlier. Still have same issues is there any external linkage or connections that would cause this?

Does it display R in the dash when shifter is in the R position?
Tranny shop and scan tool next step.

We had it scanned at auto zone no trans codes came up and it does display r on dash when put in reverse. You can hear it spin but no front tire movement. It feels like no power is getting to the front end when in reverse, sounds like every thing is working, but no movement. In drive it works and drives fine. I am stumped as to what it might be? I even looked under the bug to see if there are any loose connections or any leakage from the trans or trans axel none was found. Once again thanks for all the help.

It's an internal transmission problem. A proper scan tool can "see" TCM (transmission control module) commanding reverse. If TCM is commanding
but reverse is not engaging, the problem is hydraulic or mechanical (with whatever parts are responsible for reverse gear).
