Road Testing Vehicle

Road Testing Vehicle

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

NOTE: If a replacement transaxle assembly is being installed or a new solenoid body is installed, the powertrain control module (PCM) will have to be reflashed with a new solenoid body strategy and ID data file. The solenoid body strategy drive cycle should also be carried out.

The Shift Point Road Test and Torque Converter Operation Test provide diagnostic information on shift controls and torque converter operation.

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

3. NOTE: Shift speed ranges are approximate for all applications.

Apply minimum throttle and observe speeds at which upshift occurs and torque converter engages using the shift speeds chart.

Shift Speeds

Shift Speeds:

4. With vehicle speed above 43 km/h (27 mph), press accelerator pedal to floor, wide-open throttle (WOT). Transaxle should shift from 4th to 3rd, or 4th to 2nd, depending on the vehicle speed. The torque converter clutch should release.
5. With vehicle speed above 56 km/h (35 mph), move the selector lever from drive (D) range to L (LOW) range and remove foot from accelerator pedal. Transaxle should immediately downshift to 2nd gear. When vehicle speed drops below 32 km/h (20 mph), transaxle should downshift into 4th gear.
6. If transaxle fails to upshift/downshift or TCC does not apply and release, refer to Diagnosis By Symptom for possible causes. Diagnosis By Symptom
