Symptoms:
- Harsh shifts
- Shift codes
- Shift concerns
Cause:
Wear at the valve spools, sleeve bore and valve body allow critical control pressures to cross-leak between valve body circuits or escape to the sump. Accumulator control pressure may be high or low depending on wear location.Correction:
Sonnax oversized accumulator control valve kit eliminates cross-leaks caused by wear and retains hydraulic pressure in the intended circuits. Pressure loss to the sump caused by worn components is eliminated.A750E, A750F, A760E, A760F, A760H, A761E, A960E, A960F, AB60E, AB60F

When shift codes and shift complaints such as harsh shifts are found in Toyota/Lexus A750, A760, A960 and AB60 series units, the accumulator control valve is frequently the culprit. Worn components in the accumulator control valve train allow cross-leaks between hydraulic circuits and pressure losses to the sump. Installing Sonnax oversized accumulator control valve kit 147741-24K will eliminate cross-leaks and uncontrolled pressure loss.
