P0846 after replacing shift solenoid on 2003 Jeep 3.7 auto 42RLE

Mechanic's Assistant: How old is the transmission? Have you noticed any leaking?

Original, I just replaced the switch, no leaking this was done a week ago.

Mechanic's Assistant: What is the model of your '03 Jeep?

Liberty Sport

Mechanic's Assistant: Are you fixing your Liberty yourself? What have you tried so far?

Fixing myself. I was noticing hard shifting into 3-4 gears then my transmission went into limp mode displaying P0700. Got a scanner and pulled code P1776. Replaced the pressure switch. Then preformed the quick learn. Everything drove great for a week then I went into limp mode and also the A/C cut out at the same time. Code pulling up now is P0846

One other strange deal is the a/c will also stop working as soon as the trans goes into limp. Now I clear the tranny code to see if It wasn’t just coincidence. Started the Jeep a/c kicked in super cold as usual. Drove down the block trans went into limp mode a/c went off. Is this tied to a shared relay?
Jeep Mechanic: TIM, SERVICE MANAGER replied 3 months ago
Not a shared relay
