Overly firm up/downshift feel or harsh engagement can be a sign of deformed accumulator piston bumpers in listed units. The OE elastomeric (rubber) bumpers tend to take a set, resulting in loss of hydraulic damping. Sonnax direct-replacement accumulator piston kit 95740-15K restores hydraulic damping with improved service life.
- Hardcoat anodized aluminum valve combats premature wear
- New matching springs reproduce OE function
- Drop-in Zip Valve™ parts install quickly and easily
- Pistons (7)
- Springs (7)
Symptoms:
- Downshift clunk
- Firm shifts
- Erratic EDS solenoid control and/or EDS codes
Cause:
OE accumulator piston bumpers lose elasticity and take a set due to long term heat and fluid exposure.
Correction:
The Sonnax drop-in accumulator piston kit restores optimal hydraulic shock absorption and OE functionality to all the solenoid regulated circuits.
