Ok, so here goes nothing. 2 months ago, I, driving my 2004 Cavalier, rear ended a Ford Explorer. I have since replaced the radiator, A/C condenser, power steering reservoir, and wiper fluid tank. Of course, nose, hood and fender too. My CEL is on, and throwing P0753, which is a fault in the 1-2 shift solenoid. I have a strong suspicion that this has to do with the wiring harness going into the front of the tranny. There has been some transmission fluid in there... I am writing to see if anyone has a pinout for the connector on the front of my tranny, as well as the ECM / PCM in a 2004 Cavalier, A/T, 2.2Ecotech. I would like to test continuity between the ECM and the connector to rule that out, as well as voltage. Any other suggestions also welcome. Thanks in advance for your help.
