I just bought a new to me 2003 7.3 turbo crewcab. It is really hard to get it to shift into gear it is an automatic. You really have got to push the brake hard i mean almost stomp it. What would cause this? The guy I bought it from said it has been like that since he bought it new but there is noway it should be this hard. It also has the check engine light on he said it was a heat sensor but when I took it up to autozone they said there was no codes. Any suggestions? It only has 64000 miles.
