Just got the car out of the body shop a couple weeks ago and noticed that whenever I would shift it to R my rpms would rise which is kind of strange. Anyways I gave it no thought until I brought my car to the tire shop to get my tires rebalanced and noticed that the car doesn't move at all when when I shift it to reverse. I have an automatic by the way. After playing around with it some more the Reverse gear moves forward and so does the Neutral! The car drives fine in D mode however. Getting sick of all the problems on this car.

 

could be the linkage just needs some adjustment.
