DIAGNOSTIC ROUTINE - SOME/ALL SHIFTS MISSING

Possible Component	Reference/Action
210 - ROUTINE
Powertrain Control System
PCM, vehicle wiring harnesses, transmission internal harness, shift pressure control solenoids SSPC-A, SSPC-B, SSPC-C, SSPCD, SSPC-E, Torque Converter Clutch (TCC) solenoid, line pressure control solenoids PC-A, TSS/Intermediate shaft speed sensor, Output Shaft Speed (OSS) sensor, Transmission Range (TR position) sensor, Transmission Fluid Temperature (TFT) sensor, Accelerator Pedal Position (APP) sensor	Carry out on-board diagnostic tests. Refer to the appropriate INTRODUCTION article for diagnosis and testing of the PCM.
	Go To PINPOINT TEST A: CONTROL SOLENOIDS , Go To PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR , Go To PINPOINT TEST C: TRANSMISSION RANGE (TR) POSITION SENSOR , Go To PINPOINT TEST D: TURBINE SHAFT SPEED (TSS), INTERMEDIATE SHAFT SPEED, AND OUTPUT SHAFT SPEED (OSS) SENSORS and Go To PINPOINT TEST E: PC-A (LINE PRESSURE) SOLENOID .
	Repair as necessary. Clear DTCs, road test and rerun on-board diagnostic 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 .
