My 1990 Dodge Ramcharger with an A/T won’t move in reverse. I can get it to go into reverse when i’m in 4 low but even then sometimes is slips. It feel like the the transmission is slipping but only is reverse. Thanks for any feed back!!

 

Remove the pan and inspect for debris in pan. Sometimes if the band adjustment is too loose, the strut will drop into the pan. The strut is also part of reverse band. The front band would be your kick down band.
