My 2005 4.0 automatic TJ is having issues shifting out of second gear. Sometimes it just starts in second as soon as I put it in drive or it’ll shift down to second after running on the road for a bit. I took it to a shop and it’s throwing up codes P0562(Battery volt low), P0760(OD solenoid error), P0613(Internal TCM), and P0218(High temp operation activated). Also after looking online at some forums I think it’s the PCM. I was wondering if anyone knew how to test the PCM before I pay $500+ on a new one and it turns out it’s something else. Any advice or suggestions would be much appreciated
