SPECIAL TOOL(S) CHART

Worldwide Diagnostic System (WDS) Vehicle Communication Module (VCM) with appropriate adapters, or equivalent diagnostic tool

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 speeds chart, apply minimum throttle and observe the speeds at which the transaxle upshifts. The transaxle will upshift 1st through 6th gears.

Press 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 should release.
