SHIFT QUALITY IMPROVEMENT FOR
ACCENTS WITH AUTOMATIC
TRANSAXLES

This TSB HAS BEEN REVISED TO INCLUDE THE DOHC, CORRECT THE EFFECTIVE PRODUCTION DATE AND ADD TWO POSSIBLE CONDITIONS IN THE DESCRIPTION SECTION.

DESCRIPTION:

A modified Transaxle Control Module (TCM) is available for the Accent to reduce shift shock and/or delay during the following conditions:

1. Shift shock after shifting from P-D or N-D, then accelerating.

2. Shift shock after shifting from R-D while rolling backwards at 1-3 mph.

3. Shift shock during 2-1 downshift.

4. Excessive delay (more than 1.5 seconds) and shift shock when shifting from P-R or P-D (also N-R or N-D).

NOTE:
Excessive delay and/or shift shock may also be caused by an ATF oil temperature sensor that is out of specification. Prior to changing the TCM, test the ATF oil temperature sensor according to TSB # 96-40-001.

SERVICE PROCEDURE:





Using a 10 mm socket, remove the three bolts that mount the TCM under the driver's side of the lower crash pad, to the left of the brake pedal.
