Transmission problem
2001 Ford F150 V8 Automatic 162000 miles

I scanned my truck and got a P1780 code; "transmission control switch (O/D cancel) circuit out of self test range". I can't find what they are calling the "control switch", do they mean the control solenoid?

OD switch on the shifter KOER DTC P1780: Check Transmission Control Switch Function This DTC indicates Transmission Control Switch (TCS) was not cycled during KOER self-test. Possible causes are: Faulty TCS TCS Not Cycled During Self-Test TCS Circuit Open Or Shorted Faulty PCM Turn ignition switch to ON position. Using scan tool, select TCS PID from PID/DATA MONITOR & RECORD menu. Cycle TCS switch. Then hold switch depressed for 3 seconds, then release switch. If TCS PID value switched from ON to OFF, then indicated ON when switch was depressed, repeat KOER ON-DEMAND SELF-TEST ensuring to cycle TCS.
