TCU
After driving truck all day when I turned the truck off it would not start. I have jump the started and it will start and run but will not shift, no speedometer, no tow haul light. and only stays in 2nd gear. I suspect a relay problem in the TCU.

Eh... Ford doesn't use anything called a "TCU".

I thought this was going to be about Horned Frogs.

A 2003 F-350 diesel Automatic 4x4 could have either a 6.0L or a 7.3L engine. The systems are VERY different between the two. Which one do you have?

Great! Now we are finally getting close to what you're running. The stock Ford TCU will not work with a Cummins engine. What type of TCU do you have in it now?

This is the best thread that I've seen on FTE in ages!
There isn't even a question in the original post.

I don't think a PCS controller can control a TorqShift transmission. I know that they say it can, I'm VERY skeptical of that claim.
