Hi new to the site, having a problem with a P0974 on the 2013 AS69RC about a month after delete and Bullydog install. Have checked the harnesses inside and outside the trans, checked resistance across the solenoids and to ground all with no faults. We are getting residual fluctuating volts .5 to 2.5 volts on the #1 + solenoid wire with the key on, interchanged solenoids and problem did not follow solenoid but remained the same. Any help or comments would be appreciated. TCM p/n 05150772AG

Must be the wiring or the TCM. I would swap the Shift Solenoid 1 wires with those for one of the other solenoids, at BOTH ENDS of the harness. The solenoids each have two wires (+ and -). So, for example, I would swap the Solenoid 1 + wire with the Solenoid 2 + wire (at both ends), and swap the Solenoid 1 - wire with the Solenoid 2 - wire (at both ends). You want to unlock the individual terminals for these wires from the connectors, slide the terminals out the back of the connectors, swap them, and then reinstall them (in the "wrong" [swapped] position). You need special pick-type tools to unlock the terminals in order to swap them.

Then drive the truck and see what fault sets. If you still get P0974, then it can't be the wires, so it must be the TCM that's bad. If you now get a Solenoid 2 fault (P0971), then one of those wires is the problem.

If you need a wiring diagram and/or connector pinout diagrams, PM me with your email address and I can email them to you.

Thanks for the reply, I do have wiring diagrams and connector pin outs for all connectors, I have had every connector apart and even cut open the harnesses in any area where it showed any sign of damage, the connector in the drivers side ww had 2 pins slightly pushed back but they still made contact and were not related to the problem. I also interchanged another solenoid with the #1 and the fault remained on those wires. It does appear to be the TCM or in the wires to that solenoid. The truck is back together and not here right now so I'm working on getting a TCM to try. Swapping out a pair of wires is a good idea and wouldn't need to be swapped back afterwards, the wire pairs to each solenoid inside the trans are custom length to avoid mis-connecting but choosing one beside the #1 may work. As the solenoid connectors are all the same just different colors I could just swap them at the TCM. I'm surprised that no one has individual solenoids for the AS69RC. The solenoids themselves have a serial number like "15EM3C40424" and "13EL3C07393" but no part numbers on them and they are not physically all the same solenoid.

I was referring to swapping the wires in the external harness, not the wires inside the trans. But if you're gonna do that (swap inside the trans), then you could do both (internal and external) at once. Swap the terminals at the TCM end of the external harness, and then swap which solenoid those same wires are connected to inside the trans. That way you will be swapping both the external and internal wires at the same time.

If it now sets a fault for the "other" solenoid, then you would swap again (but ONLY the internal OR external wires) to figure out which one of those is the problem. And then (suppose the fault follows the external wires), swap only the + wires (or the - wires) to determine which one of those is bad.

Hope that's not too confusing!

Not at all, The connector on the outside of the trans is a sealed connector but also "filled" on the back side to avoid contamination as it's installed up side down.

Just to update and let everyone know if they get codes similar that it's NOT necessarily the valve body, it was a broken wire, the very flimsy kind of wire that Dodge uses. The dealer wanted to replace the complete valve body. Thanks to TransEngineer for replying.

Where was the wire broken? I’m currently in the same shape you were. Found some wires in the harness behind the fender liner on drivers side, repaired them.. still nothing. If you clear the code, as soon as you start the truck back up it throws the code again.

That was his last post. I don't think you will hear back.
