I recently ran into an issue with a no start on my 2003 f350 6.0. The error code it gave me pointed to the Transmission range sensor so I replaced it with a new one. When that didn't help I put a new internal wiring harness on. After that didn't fix it I did some research and found that the fan clutch was the issue causing the no crank. But after replacing the transmission range sensor and the internal wiring harness my truck will only shift into 5th gear and then gets stuck in 5th. I know it's stuck in 5th because I hooked it up to forscan to see what frequency the transmission range sensor was putting off and to see what great it was in. Has anyone seen this before?
