I have a 2004 Heritage I'm fixing up for my son, the trans was bad when we got it so my father in law rebuilt it (he has a lot of years of experience with ford transmissions) It doesn't shift out of low gear from drive the speedometer doesn't go past 15 mph so I changed the VSS still the same so I tried the MLP sensor still the same so yesterday I cranked it and the OD light was flashing and the odometer was flat lining no numbers so I decided to drive it and it shifted fine I went a few blocks and the numbers came back on the odometer and OD light quit flashing. It also quit shifting it has both of us stumped
