OK so been having some on going issues. Here is wants happened so far. CEL came on with cylinder 1 injector misfire, replaced injector worked a bit then light came back on. This time went to dealership as told issue was both speed sensors. Had a 700 code replaced the input and output speed sensors light still on. I had my code reader come in plugged it up and was getting a shift soleniod code. Replaced shift soleniod and now getting random codes, gear 2 ratio, shift soleniod once, input sensor again, oil pressure switch error. Not sure what the issue is now with this thing. Any suggestions I did get a new battery and new Trans oil filter when I did then shift solenoid swap. RecentLydia did a oil change as well as did spark plugs. Tyranny isn't shifting hard actually shifts smooth when it does decide to. Recently my gauges also went crazy but turned jeep off and they went back to normal. Any help or suggestions I'm out of ideas.
So today it was giving me the shift solenoid until I tried to get it past 2000rpm then switched to the input speed sensor code. Which they both are new.
Ok so after a new pcm and thousands more going back and forth to mechanic, finally got it fixed. After new pcm still had codes found multiple shorts in transmission. Wires. However what seemed to do the trick was the transmission relay leads were the problem. Took apart the fuse box and found a wire had been pretty messed up.and coming out of the pin for the relay to connect to. I redid the wires and pushed them all the way in and works great. Even put old pcm back in and works great. So have the new one for sale if any takers.
