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 circits 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.
