Hi,
I have a couple problems with my M1045a2
First problem is that my transmission is in "limp mode" only does 1-2 gear. I have put the transmission in diagnostic mode with a "jumper" and the code is 7-3 that says problem with the Pressure Control Solenoid. I have cheked the wiring and cant find any shorts on the wiring for the transmission. So I am ready to change the PCS to see if that will fix the problem. The PCS is inside the transmission, I have to drop the pan to get to it. Can I just drain the transmission for oil and pull the pan and change it? What is the procedure after the drain and fill up do I have to cycle it throug every gear to make the oil float around in the transmission?
After this is done i read that I have to reset the errorcodes with pushing the red button behind the passenger seat. Shall it pressed when the HMMWV is running, ignition on, ignition off or with the battery disconnected?
The second problem is when I disconnect the negative on the rear battery the lights still can operate on 12v. The +14 output on the regulator makes a negative. Is it supposed to be like that?
