LOL i didn't even notice it was his signature... i thought he was tell us his build:rofl:
It's matts 01 truck that I built for him he said that after he did a burnout last week it started throwing these codes. I know its the converter stuck on and trim valve B
Allison's do not like burnouts... at the track put it in 2nd gear when you want to.
Who built the trans and was the builder notified of the problem? Posting this info here without us knowing what the builder did and didn't do could be useless.
So the codes mean something different depending on who built it?
No, but knowing what is done inside the transmission can help figure out why the truck is throwing the codes.
Exactly.
The code thrown does not neccessarily pinpoint what's wrong. Sometimes the ECM/TCM will detect problems that they are not programmed to detect, and when that happens they will throw a code that might not have anything to do with the actual problem.
