just put a used trany in my '97 f150 4x4 4.6l .....now this used trany i got complete...with another truck..running of course..drove it around a couple hundred miles before stripping it down...trany shifted and worked great..

now it will not shift in drive...can make it shift manually from 1st to 2nd but have no 3rd.......all fluid was changed as well as the electronic piece at the shifter........both trucks were 1997 4x4 4.6

ideas anyone........
