Trans shifts are 1-2-3- TC lockup-OD. TC locks up in 3rd no matter what.

 

With O/D enabled, mine will hit forth, and then engage TCC. I think........

 

The TC locks up first no matter what the OD button is set to. The TC is already locked up when it shifts to OD.

 

If your in ohio, get a hold of wallie at FTE Diesel. He should be able to help you out

 

My truck doesn't seem to have the OD button on the dash. I have pulled the whole dash off looking for this button and there is no wiring or anything where the button should be? Could this be my problem?

 

The truck just started throwing codes now.

12 Direct battery input to PCM was disconnected within the last 50 key-on cycles. I disconnected both batteries to try to reset it.

24 Throttle Position sensor out of range

24 Throttle Position sensor out of range, Throwing this code twice

55 End of error messages

 

The TPS code is the main one I am concerned about. I think the problem is narrowed down to this. I just put a volt meter on the orange signal wire and the ground and it is reading .01V. It is supposed to read between .08 and 1.2V what could cause this? The TPS is brand new.

 

Bad TPS?

Did you reset the PCM after replacing it?

 

I disconnected the batteries. That resets the PCM right?

The TPS is brand new.

 

Just because it is new, does not necessarily imply that it is good.

Yep, disconnect battery for a few will reset everything.
