Upshift Procedure

With gear selector in drive (D)

1. Look at the shift speed chart contained and choose a percent throttle angle of 10 or 25%.
2. Set up the scan tool to monitor throttle angle and vehicle speed.
3. Accelerate to the chosen throttle angle and hold the throttle steady.
4. As the transaxle upshifts, note the shift speed and commanded gear changes for:
   • Second gear.
   • Third gear.
   • Fourth gear.

   Note when TCC applies. This should occur in fourth gear. If the apply is not noticed by an RPM drop, refer to the "LOCK-UP CLUTCH DIAGNOSIS " information contained.

   The lock up clutch should not apply unless the transaxle has reached a minimum operating temperature of 8 °C (46 °F) trans temp. and engine coolant temp. of 50 °C (122 °F).

5. Repeat steps  1 -  4 using several different throttle angles.
