Then a few days later I was just driving through town and the CEL came back on. Check for voltage on the power side circuit of the TCC solenoid or at the wire harness connector at the TCM with the DVOM set to volts scale, positive lead at the wire being tested and the negative to a known good ground with the vehicles key on/engine off, battery voltage should be present.

Resistance should be very high or over limit (OL), if it is low, suspect a short to ground. In the case of the P0700, it is a general code. At a shop, the replacement cost is between $200-$300 depending on the car, Please fill the "Code Box" to find engine fault code. start stalling a lot.

So you should chech it on our car models. However manufacturer may have a different definition for the P0741 OBD-II Diagnostic Powertrain (P) Trouble Code.

Using a digital volt ohm meter (DVOM) set to ohms scale, check for a short to ground in the circuit with the positive lead on either pin and the negative lead to a known good ground. I had a parts store check the code and it came up with P0741 (TCC stuck OFF) and P0700 (ECM issue with transmission and shifting if I remember correctly). I took it back to the dealership and they first changed a solenoid (or so they stated) for the Torque Converter, the CEL was OFF when I got my truck back. Minimal decrease in fuel economy, this will not affect engine performance Lock-up piston operation will then be controlled. The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. If resistance is low, suspect a short to ground the internal harness or the TCC solenoid - removing the transmission oil pan may be necessary to further diagnose the TCC solenoid.
