I have a 2003 Ford Ranger 4x2. It will shift into 1 and 2 fine, but no Drive or reverse. When put into reverse it acts like it wants to move, but doesn't. The transmission was re-built just over a year ago and this is the first issues we have had since. Ran a code check on it and it is not giving any transmission codes. No idea where to start with this as I have never done much with them. any assistance would be greatly appreciated.,
