Shift Point Road Tests

NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

Shift Point Road Test
This test verifies that the shift control system is operating properly. Perform the test as follows:
1. Bring engine and transaxle up to normal operating temperature.
2. Operate vehicle with selector lever in by, D range.

AX4N Shift Speeds-approximate MPH:

3. Apply minimum throttle and observe speeds at which upshift occurs and torque converter engages.

NOTE: Shift speeds may differ on altitude.

4. Stop vehicle and move transaxle range selector lever to D range. Repeat Step 3. Transaxle will make all upshifts except 3-4 and torque converter clutch apply should occur.
5. Press accelerator pedal to floor, wide-open throttle(WOT). Transaxle should shift from third to second, or third to first, depending on vehicle speed, and torque converter clutch should release.
6. With vehicle speed above 48 km/h (30 mph), move gearshift lever from D range to 1 range (LOW) and remove foot from accelerator pedal. Transaxle should immediately downshift to second gear. When vehicle speed drops below 24 km/h (15 mph), transaxle should downshift into first gear.
7. If transaxle fails to upshift/downshift or torque converter clutch does not apply and release, refer to Diagnosis by Symptom Index for possible causes.

NOTE: Shift speed ranges are approximate for all applications.
