Ah, I see. You want to outsmart the computer? Right logic, wrong computer. I think the problem is not in the transmission, but it is the engine computer that has communicated with the transmission computer and put the car in limp-in mode. The fix engine light is sent from the engine computer, and this is the main computer in the car, the main drive train computer, if you will. The short answer is yes it will reset, by just unhooking the battery. Won't do any harm. Start it up about an hour later, and be sure and let it warm up to normal operating temperature (closed loop) before you take it out for a test drive. Otherwise you may be miles from home in 2nd gear limp-in mode again. The real fix is to talk to your car...like communicate with the computer and get those trouble codes read...talk to it nice, not the abrupt tone of the glaring idiot light, and maybe it will respond in a kinder, gentler easy to fix diagnostic code!!!! Good luck.
EPC = Engine Power Control it's the engine control module yellow warning light. You need access and erase the EPC memory by DTC (Diagnostic Trouble Codes) using diagnostic equipment connected to the data link connector of the car, in order to reset the EPC, and turn off the EPC yellow light.
that dash ligfht is called the check engine light, this means a fault has occured in the electronic engine control system, there are many faults that trigger this light, well over 200, to find out what the problem is you will need to have the system tested for the trouble code that is stored in the computer, anytime the check engine light is on there is a code set in memory
GOOD! I assume the CHECK ENGINE (yellow) light comes on!... correct? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there.
