05 LJ Rubicon, Automatic
I started with code P0740 that I pulled from a scanner. I took my LJ to a reputable transmission shop for further diagnosis. They came back with additional codes P0218 and P1775. They suggested replacing the solenoid, changing the fluid and then see how things are after that.
I was very surprised at the P0218. Years ago Blaine swapped out for me a transmission pan with a temp sensor and I installed a temp gauge. I have monitored the transmission temp ever since and never has it been over 200. That lead me down the rabbit hole of the PCM threads. I don't think the tranny shop is familiar with the PCM issues as a possible cause of the P0218. I did not see in the PCM discussions code P0740 discussed.
Given these codes, what is my next step after the solenoid is replaced? Just replace the PCM? I have not had hard shifting issues from 1-2 as others reported.
