Ford Escape XLT 3.0L 4x4: I own a 2001 Kenne Bell Supercharged

Customer Question

I own a 2001 Kenne Bell Supercharged Ford Escape 3.0L 4x4 that occasionally throws a P1744 Torque Converter Clutch System Stuck in Off Position code and the dash O/D Off light will blink until I turn off/restart the vehicle. I had the transmission rebuilt about 8K miles ago including a new torque converter. Is this code due to a solenoid or wiring issue or is it a mechanical? Is the solenoid located within the transmission? Can this problem be resolved without having to drop the transmission?

Yes it could be a TCC solenoid failure and it is servicable by removing the trans front pan. Here are some details on the dtc: ssible CausesSetting ConditionsCheck the transmission internal components for problemsTCC solenoid has failedTCC solenoid has a mechanical problem (e.g., solenoid stuck on/off)Engine running; vehicle driven for 2-3 minutes, and the PCM detected an excessive amount of transmission (TCC) slippage during normal driving; or it detected erratic TCC operation or no TCC operation.COMPONENT MONITOR DRIVE CYCLE INSTRUCTIONSDo not turn off the ignition switch during the test procedure.All Onboard System Readiness (OSR) codes are cleared when the battery is disconnected or when the Powertrain Control Module (PCM) is cleared with the Scan Tool.This drive cycle can be used to determine if the Readiness code for this Monitor will run and complete, and if the MIL will remain off after the vehicle is driven.Operating Ranges: Whenever a range of values is provided, try to operate the vehicle in the middle of the range. For example, if the vehicle speed range calls for 45-55 mph, operate the vehicle at as close as possible to 50 mph. Or if the engine speed should be 1,000-2,000 rpm, try to operate the engine at 1,500 rpm.Scan Tool Data: There are certain Parameter Identification (PID) values that must be within range before this Monitor will "run". It can be helpful to pull up those PID items on the Scan Tool so an assistant can view them during testing.The Readiness code for this Monitor defaults to "continuous" or "monitoring" because this Monitor runs continuously when the engine is cranking or running. COMPONENT MONITOR PRETEST CONDITIONSMIL is off.No Emission related DTC's are present.IAT sensor signal between 40-100ºF. TEST PROCEDUREConnect the Scan Tool to the data link connector (DLC). Turn the key on and bring up the ECT PID and IAT PID on the Scan Tool. Verify that the IAT PID is between 40-100ºF.Use the Scan Tool to clear any stored DTC's and to reset the OSR Monitors. Note that DTC P1000 will appear once all of the trouble codes are cleared. Start the engine without turning off the ignition key. Allow the engine to run at idle speed for 15 seconds.Accelerate at part-throttle to 40 mph and maintain that speed until the ECT PID reaches 170ºF (77ºC). Bring the vehicle to a stop, and then allow the engine to idle with the transmission in Drive (in Neutral for M/T) for 2 minutes.Then accelerate at moderate throttle in Overdrive (if equipped with O/D) to 50 mph (80 km/h) and maintain that speed for 15 seconds. Bring the vehicle to a stop, change out of Overdrive, and then accelerate to 40 mph (64 km/h) and maintain that speed for 15 seconds. Bring the vehicle to a stop and allow the engine to idle for 15 seconds. Repeat this step at least 5 times.Check for any Pending codes in the Generic OBD II section of the Scan Tool. If no Pending codes are set, the Component Monitor test is complete. If any Pending codes are set, refer to the appropriate trouble code repair information to make the repair.
