I had a leak by the transmission control module (solinoid) I bought a new solinoid TCM and replaced it. About 3 weeks later it would go into limp mode (2nd) but it did not set off check engine light. Then if you shut it off and restart it everything is normal. Now it went into limp mode and the engine light came on and it is throwing codes p0700, p0725, and p0841 and will not let me reset it out of limp mode. Any ideas what this might be?????

 

Update; found out after some looking around and talking to my Dodge dealer that the transmission control unit is shot and the p0841 was this thing being messed up inside and throwing false codes (p0841 is very rare). The unit is cracked around the seams and the housing is even falling/flaking off in chunks it is so corroded (nice spot for one of these things) Has anybody replaced one of these and how much did it cost for the unit??

I am having a hard time understanding what you are asking. But are youasking about trans case or the solenoid pack??? Or maybe the TCM? I am a dodge trans tech so send me an PM if you want.

 

so nobody has had to buy one of these yet?? they might be called a ECM or a TCM they are located behind the inner fender (drivers side) right behind where the fog light is ??
