Anyone have any idea on where to start with these codes? Jeep drives and shifts fine. Fuses and relays look good. I don’t see anything glaringly obvious with the wires but I’m not confident I’m looking in the right place. Any previous experience with codes p1603 and p0700 would be appreciated.

So I disconnected the battery, took apart all the electrical connectors on the transmission and PCM, sprayed them with electrical cleaner, covered them in dialectic grease and plugged them back in. The code is gone for now.

Does the check engine light come on with the key on?
Yes, it looks like a failed PCM :rolleyes:💪🚗
