问：变速箱不稳定，如果问题出现在TCM中，它会抛出故障的TCM代码吗？或者不是所有的时间。
2007 Dakota V6 Tranny 42Rle不错的转移替换了Hidraulic Fluid，新的过滤器，机械师代替了压力转移硒，问题没有消失，然后更换的Pack Selenoid问题继续不断地移动大部分时间，大部分时间都在li行的lim锁中，除了所有提及的卡车运行时，，毫不犹豫的发动机运行平稳的机械师说，挂接扫描仪P0760时会出现2个代码，这表明Shift Selenoid“ C”上有故障，另一个代码是P0870液压压力线故障，他对我说，他不向我说，他不是对我的专家电动变速箱区域，但他估计问题是糟糕的地面电路或TCM本身。请告诉我您的意见，卡车有120000英里，而Ive Aready花了579.00 dlls。在这个家伙，我负担不起更多的钱，请提供帮助。
我的汽车有120000英里。
我的汽车有自动变速箱。

Hello and thank you for contacting Your Mechanic. The codeP0760means that the shift solenoid "C" is operating irregularity. The code P0870 means that the transmission fluid pressure is not determined at its specified pressure.
Check the harness to the transmission and make sure that everything is plugged in. Check the main harness for corrosion and any debris on the contacts. If the harness checks out to be okay, then the problem lies within the transmission. The shift solenoid "C" is probably getting too hot and shutting down. The pump pressure solenoid is not functioning correctly and is maxing out the oil pressure causing harsh shifting.
I recommend replacing the shift solenoid "C" and the pump pressure solenoid. If the problem continues to persist, then the transmission oil temperature sensor could be failing. This symptom results in low fluid, failed pump, slipping transmission, or the computer has lost its memory and needs flashed or replaced. However, I suggest replacing the shift solenoid "C" and the pump pressure solenoid first before doing anything else.
