2005 TJ Transmission

I have a 2005 Jeep Wrangler TJ Sport with a 4.0 and automatic 4 speed transmission. About 2 weeks ago the service engine light came on then the transmission would not shift past 2nd gear. I pulled to the side of the road, shut the engine off, looked under the hood, and checked fluids. I could not see anything wrong so I decided to drive the Jeep home slowly. When I started the Jeep the engine light was still on however the Jeep shifted fine. The next time I started the Jeep the engine light was off and it drove fine.

The Jeep has done this 8 times since then. I scanned the Jeep and it threw P0700 Transmission Malfunction Present, P0760 Shift Solenoid C Malfunction, & P0871 Transmission Fluid Pressure Sensor/Switch C Circuit Range/Performance.

I took the Jeep to a local transmission shop and he scanned the Jeep coming up with the same codes. They have replaced the shift solenoid pack, the fluid, and the filter. The Jeep drove great for 2 days then it did the same thing. I have not had a chance to re-scan the Jeep so I do not know what codes it is displaying now.

I was just wondering if anyone else has had this problem, or has any expertise in this, and if so what fixed it.

I think 2005 was one of the years that had PCM issues. Im sure somebody will chime in. Only other thing i could think of would be sticking valves in the valvebody. Those transmissions have a solenoid switch valve that sticks. Its part of the valvebody not the solenoid part.

Same exact problem here, 2005 replaced the solenoid and everything worked fine for 2 days and now it's back again. Ever find out the problem?

same exact scenario here. Im not happy

2 days after havin the silenoid replaced it stuck in 2cnd gear, turn of motor shifts now but codes P0700 P0776 wont clear. I dropped $900 a the dealeship 3 days ago and this shit happens again. Id like to find an alternate but superior transmission replacement.
Im not sure what to do at this time.

The dealership should warranty all their work, go back to them and complain, loudly

I have a 2005 Jeep Wrangler Rubicon with an automatic transmission. It got stuck in second gear and could be reset by turning the ignition switch on and off. I took it to the dealership for times. They replace the solenoid the Valve body installed a transmission cooler and it replaced PCM each one of these fixes did not fix the jeep so now I've got $2000 in his Jeep and still have a transmission to get stuck in second gear needless to say I'm pissed off I really don't know where to go from here but I think I might not ever own a jeep again
