Procedure

1. Install new PCM/TC calibration according to the calibration chart. (Refer to "Reprogramming EEPROM" in the "Service Stall System User Guide.")

IMPORTANT:
Version 38.5 or greater Service Stall System (SSS) software is required for this flash process. Verify the SSS is version 38.5 or greater.

If SSS version 38.5 or greater is not available, call Saturn Customer Support Center at 1 (800) 7SATURN (1 (800) 772-8876), prompt 3. In Canada, call 1 (800) 828-6860 for English, or (1 (800) 503-3222 for French.

2. To verify repair, perform the following test:

a. Operate vehicle until transaxle temperature reaches 70°C (158°F).

b. Place vehicle in Park.

c. Apply parking brake.

d. Connect Scan tool and scroll to monitor transaxle oil pressure.

e. Place foot firmly on brake.

CAUTION:
TO PREVENT POSSIBLE PERSONAL INJURY, MAKE SURE WHEN PERFORMING THE NEXT STEPS THAT THERE ARE NO PERSONS OR OBJECTS IN FRONT OF THE VEHICLE.

f. Place vehicle in Drive.

g. Lightly engage throttle (less than two percent as monitored on the Scan tool), while monitoring transaxle oil pressure, slowly increase throttle until transaxle oil pressure increases to above 800 kPa (87 psi), or until a bump and/or racheting sound is heard, and release the throttle.

^ If a bump and/or ratcheting sound is not heard when transaxle oil pressure has increased to above 800 kPa (87 psi) the vehicle has been repaired.

^ If a bump and/or ratcheting sound is heard before transaxle oil pressure has reached 800 kPa (87 psi), refer to the appropriate year automatic transaxle service manual for DTC P0731, "Transaxle 1st Gear - No 1st Gear" and follow the diagnostic trouble tree.
