Harsh Engagement into Reverse. Saturn Saturn 1992

For 1990-2009 cars

# Harsh Engagement into Reverse

Subject: | Harsh Engagement into Reverse (New PCM Calibration)

Models: | 1992 SL2 Sedans and SC Coupes equipped with MP7 automatic transaxles and vehicle identification number (VIN Z113023 and below.

### Condition

A harsh engagement is experienced immediately after shifting into reverse (R).

### Cause

The harsh engagement into reverse may be caused by a PCM calibration error. This condition has been corrected on vehicles built after VIN NZ113023

Normally the Saturn automatic transaxle will have a 1-3 second delay before engaging into reverse. If a customer comments on a harsh shift into reverse, with a quick clutch engagement (usually less than one second), then a new calibration may need to be downloaded into the PCM.

### Correction

If a harsh/quick engagement is verified, download #2548 PROD TC CALIBRATION using Saturn Service Stall System and the "How To Use SSS EEPROM Reprogramming" procedures in the "SSS User Guide".
