I recently purchased a used 2001 E350 with a 7.3L and the transmission is not shifting properly. It will go into Reverse no problem, put it in "D" and it starts in high gear and will not shift out. If I manually shift from 1 to 2 to "D" it works fine and will even go into OD. It will not down shift on its own either. What should I do to fix this issue?

 

First, get the codes read. The places that read codes free CANNOT read these codes.

 

Ok, will do. I tried Oreilly today and they said nothing was showing. The check engine light is not on and the only light on is the ABS. Will go tomorrow to shop to get a real scan. Thanks.
