Thanks. Open to any suggestions. Mainly what I was asking was if pin 71 was input/output or what. Whether voltage should be coming from tcm side or harness side
Does wire 71 have 12V or better? Looking at the pins tells you nothing unless it's damaged. Voltage will be coming from the battery. You need a wiring diagram and a DVOM. The diagram will tell you where 71 goes. Check voltage at the source then follow the wire down to the TCM and see if there a break or rub through. Check all fuses.
Check voltage to the trans with a professional scanner.
Once you fix P2670, the others might go away as well.
Check fuses, and then get a wiring diagram. My diagrams only go up to 2005, so I can't help there. Once you get that sorted out, I bet the other codes go away.
The way it limped makes me think I have something sticking it the valve body. I'm no transmission expert. But I contacted the builder and that's what they are sending so hopefully it will
