Showing p2670 code. Comes back as soon as code is cleared with scan tool. And can't really find any info on it.

Not trying to answer for Mike L, but I'd check the connector to see if the pin for 71 has backed out based on what Mike L has posted.
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.

That's your problem.
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.
All fuses are good. My builder is sending me a valve body and internal harness and hopefully get it back going
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
so did you ever check power at the trans like Mike said?
if your showing .40 where its supposed to be 12v+ then that might be part of your issue...
