Thanks rebel...I should Have told you the first time you said it that I will do that next so you didn't think I was avoiding doing that. So im gonna do that asap and on the 17th the shop is gonna take a look again and check the new ecu that I installed. I will report back. Thanks again for everyone's help.

I know for sure in our 4 year ownership it hasnt...Idk about before that. In a trans diagnostic from a transmission shop, would dropping the pan and checking that stuff, be a part of the diagnostic?

140.xxx miles The lube tech said there was little to nothing in the way of metal when it was being flushed. I know that don't mean there isn't any in the pan though.

Ok guys im back. So we took the journey to a trans shop and they said it seems like a weak battery. So we got a new one. Same issue. So we took it back to the shop.They went over it again for free. This time they said the issue is the ecu. Got a new one...installed it 3 days ago and today...the same damn issue!Same code (p0750). Idk guys..Ive hit a wall with this thing.

So a little update.... Ive done nothing else to it and I took it out of the driveway to move another car in and I noticed it was working as normal. So I took it to go get parts for my denali and it worked beautifully! Then 7 days later..it messed up again. Why would it work fine for a week? Electrical issue? Ecu on the way out?

Sorry guys for the confusion...This is from the vin info. I put L4 but its I4. Manufacturer: Chrysler Mexico Brand: Jeep Model: Journey Engine: 2.4L I4 Region/Plant: Toluca Mexico Check: 7 Year: 2012 Sequential number: 55594

Yes and I checked the vin online and it shows the 2.4 L4

So I just realized you said "62te" and I understand thats the one that come in my year DJ but I believe I have the 41te. Does your advice still stand for the 41?

Thanks rebel...I will get that looked at asap. Also a little update..I went out to double check my work, make sure everything was plugged in right and if I had messed anything up. I pulled the rpm sensor to make sure the contacts were good and I didn't crack it or anything then popped it back in, cleared the codes and took it for a test drive. It performed just fine till I got to the second block and I felt a jerk and now I am back to the original problem I had before these new issues. It will no longer shift out of first but it don't feel like its slipping anymore.

So I have a 2012 and I recently had an issue where it would not shift out of 1st. A code popped up (p0750) So I replaced the trans control solenoid. Car shifted into all gears now but I was concerned about the dark brown fluid. So I ran to the local lube shop and had them flush the trans with 12qts. Took the car and it shifted as smooth as can be through all gears. Its now 4 days later and I get 2 codes(P0731 gear 1 incorrect ratio P0846 trans fluid pressure sensor/switch n circuit range/performance) Along with the codes it seems to slip a bit and jerk going into 2nd and then slam into 1st from 2nd when coming to a stop. I know that flushing the old fluid can cause slipping but I can think of anything else it could be besides that. I don't wanna get the trans rebuilt or replaced if its something I can fix at home. So if anyone has had this issue or knows what I can check I would appreciate the help. If you need more info or questions answered..let me know. Thanks!
