Note. Shift speed ranges are approximate for all applications.
This test verifies that the shift control system is operating correctly.
- Bring engine and transaxle up to normal operating temperature.
- Operate vehicle with selector lever in D range.
- Using the shift speed table, apply minimum throttle and observe the speeds at which the transaxle upshifts. The transaxle will upshift 1st through 6th gears.
- Press the accelerator pedal to the floor, Wide Open Throttle (WOT). The transaxle should downshift to the next lower gear depending on the vehicle speed. The Torque Converter Clutch (TCC) should release.

- If the transaxle fails to upshift/downshift or the TCC does not apply and release, refer to «DIAGNOSIS BY SYMPTOM»(ref-355918-S18909871672010013000000) for possible causes.

Prior to torque converter installation, all diagnostic procedures must be followed. This is to prevent the unnecessary installation of new or remanufactured torque converters. Only after a complete diagnostic evaluation can the decision be made to install a new or remanufactured torque converter.
Begin with the normal diagnostic procedures as follows
- Preliminary Inspection
- Know and Understand the Customer Concern
- Verify the Concern - carry out the torque converter operation test
- Carry out Diagnostic Procedures: Retrieve and record all DTCs. Refer to «DIAGNOSTICS»(ref-355918-S06501105262010013000000) . Repair all non-transaxle related DTCs first. Repair all transaxle DTCs. Carry out Pressure Test. Refer to «SPECIAL TESTING PROCEDURES»(ref-355918-S01550574302010013000000) . Carry out Stall Speed Test. Refer to «SPECIAL TESTING PROCEDURES»(ref-355918-S01550574302010013000000) . Carry out diagnostic routines. Refer to «DIAGNOSIS BY SYMPTOM»(ref-355918-S18909871672010013000000) . Use the index to locate the appropriate routine that best describes the symptom(s). The routine will list all possible components that may cause or contribute to the symptom. Check each component listed, diagnose and repair as required, before repairing the torque converter.
