Shift Point Road Test

This test verifies the shift control system is operating correctly.

  1. Bring engine and transaxle up to normal operating temperature.
  2. Operate vehicle with the selector lever in D range.
  3. NOTE: Shift speed ranges are approximate for all applications.
  4. Apply minimum throttle and observe the vehicle speed when an upshift occurs and the torque converter engages using the Shift Speeds chart.

    (1) Do not exceed the speed limit.
  5. With vehicle speed above 43 km/h (27 mph), press the accelerator pedal to Wide Open Throttle (WOT). The transaxle should shift from 4th to 3rd, or 4th to 2nd, depending on vehicle speed. The torque converter should disengage.
  6. With vehicle speed above 56 km/h (35 mph), move the selector lever from the D range to the L range and remove foot from accelerator pedal. The transaxle should immediately downshift to 2nd gear. When vehicle speed drops below 32 km/h (20 mph), the transaxle should downshift into 1st gear.
  7. If the transaxle fails to upshift/downshift or the torque converter does not apply and release, refer to DIAGNOSIS BY SYMPTOM  for possible causes.
