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.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
