Bigtime update on my torque converter clutch solenoid problem.

This verifies the confusion as to why my connecter is black! Remember, I said that the low impedence solenoid body had the black connecter and was phased out during the 95 model year. During that same year, a new high impedence solenoid body was introduced that had a beige (natural) connecter. All CD4Es from the years of 93-95 can have either solenoid body with no adverse effects. Put one of the low impedence solenoids in a post 95 CD4E and there will be problems. It also verifies what Roadrunner was telling me in the end, that the code was being generated because the PCM was not sensing the proper amount of resistance from the solenoid, hence the code P0743 once the car reached open loop operation.




I have just installed a remanufactured CD4E in a 98 Contour and I am having numerous problems with the shifting. The car seems to start in 2nd gear, immediately downshift to 1st gear and then shift back to second and then to third. It does this rather erratically. Also the Torque Converter Clutch seems to drop in and out when cruising at 50 MPH. The only DTC I get is a P0743. The reason I ask in this thread is because this is a 98 Contour and the remanufactured CD4E has a black Transaxle Harness Connector and I am measuring a TCC solenoid resistance of 1.5 Ohms rather than the 12.5 - 19 Ohms specified in the Mitchell manual. I do not remember what color the connector was on the old transaxle, the core has already been sent to the remanufacturer. Do I have the wrong valve body installed in my transaxle???? Has it damaged the PCM???????

thanks
