DIAGNOSTIC ROUTINES - SOME/ALL SHIFTS MISSING

Possible Component	Reference/Action
210 - ROUTINE
Powertrain Control System
PCM (gasoline engines), Transmission Control Module (TCM) (diesel engines), vehicle wiring harnesses, transmission internal harness, Shift Solenoid Pressure Control A (SSPCA), Shift Solenoid Pressure Control B (SSPCB), Shift Solenoid Pressure Control C (SSPCC), Shift Solenoid Pressure Control D (SSPCD), Shift Solenoid Pressure Control E (SSPCE), Torque Converter Clutch (TCC) solenoid, Pressure Control Solenoid A (PCA), Turbine Shaft Speed (TSS)/intermediate shaft speed sensor, Output Shaft Speed (OSS) sensor, Transmission Range (TR) sensor, Transmission Fluid Temperature (TFT) sensor, Accelerator Pedal Position (APP) sensor	Carry out On-Board Diagnostic (OBD) tests. Refer to the INTRODUCTION - GASOLINE MODELS for diagnosis and testing of the PCM. For gasoline engines, GO to PINPOINT TEST A , GO to PINPOINT TEST B , GO to PINPOINT TEST C , GO to PINPOINT TEST D and GO to PINPOINT TEST E . For diesel engines, GO to PINPOINT TEST F , GO to PINPOINT TEST G , GO to PINPOINT TEST H , GO to PINPOINT TEST I and GO to PINPOINT TEST J . Repair as necessary. Clear DTCs, road test and rerun OBD test.
Some Shifts Missing Only
	If only some shifts are missing, determine which shift(s) do not occur. Use the Band, Clutch, Solenoid, Switch Application Chart and monitor the appropriate PIDs. Refer to SPECIAL TESTING PROCEDURES .
