I have a 93 Dodge W250 with 5 spd manual xsmn. If I come to a stop in a parking lot and need to shift into Rev. to back up, shifter will not go into rev (or any other gear). the only way I've been able to get the shifter to move is cycle the transfer case lever from 2w to 4w. this takes several to many trys to get the shifter to finally get into Rev. Also when driving and shifting from 2nd to 3rd if I do it gently the shifter doesn't want to come out of gear easily. I have to leave truck in 2nd, and make a more aggressive acceleration and shift to make the shift to 3rd. Any ideas how to fix?
