So heres the deal winter has arrived here and started jeep the other day and went to leave driveway and jeep stalled when put into drive after reverse. Started right back up and MIL light on checked code and found it was a p0841 Transmission Fluid Pressure Sensor/Switch A Circuit Range/Performance just wondering where I should start looking any help would be greatly appreciated
I just did one of these the other day, I removed the transmission pan and found a screw on filter had backed itself off. Good luck, transmissions are hard to fix this should keep you busy for a while that may know if you need more information

Inspect the wires make sure you check the screw on filter make sure it is not lose, give it a general inspection and double check your work.
