Let me share some some info with you guys.
 

So I was at work today and we were diagnosing a condition on a e550 van with a 7.3. It started and ran fine, but eventually if you got in it too hard it would just stall. Also, if you put it in reverse, hold the brakes, and give it gas, it would just cut out at around 1700. It sounded like turning off a key. it turned out to be a transmission wiring harness.

Transmission wiring harness? WOW! Was it burnt?

We dont know. Found the problem at 5:29. I'm pretty sure that something is rubbing against it, cause the wires to short like hell. But we will know tomorrow.

What Trouble codes did you get?:humm:

didnt pull any trouble codes
