Thank you. Im still tryin to figure out if my transmission is gone or if it just needs a fluid and filter change. P0841 is the code. So if its not the fluid or filter then maybe the pressure sensor switch. I'm not a mechanic at all lol just looking for info and a mechanic LOL if theres any near Seattle WA area? That would be awesome! :) thank you billwill. For the link. :)

P0841= LR Pressure Switch Sense Circuit
When you say is revs to 4000 is that while driving ? Does it feel like clutch plates are worn and slipping to 4000rpm?
How many miles on your Jeep? Trans fluid & filter should be done at 60k miles.
On level ground after driving when hot, is the ATF+4 fluid at the full mark on dipstick, clean or smell burnt at all ?
The 42RLE transmission is computer controlled and get a transmission shop to use their scanner to retrieve codes...
