I have a 2011 Ram Dakota 3.7 v6 that will not reverse. In drive it shifts fine, no other apparent issues, but when I put in reverse, I can hear it shift into gear I think, but when I hit the gas, it revs like it is in neutral. Only thing I have done that might have caused it was pressure wash the undercarriage a little bit meaning might have messed with the cables underneath if any of them are related to the issue, which I am not sure. Any ideas or help would be appreciated

 

Get up under and look for loose, disconnected linkages. Otherwise, get it to a shop for a proper diagnosis.

 

Thank you for the reply! I will take a look when I get off work.

 

@jkeaton The linkages are all connected, and I had someone watch the shift linkage while I shifted. Confirmed it does shift into reverse, and the linkage is working but thinking maybe the cable lost its tension, or the gear itself is just gone maybe? Also as a note, sometimes while in reverse, it will roll back on its own for about 2 feet then stop, while the gas still does nothing. Any ideas? Might be able to get it onto a lift tonight to get a better look.
