This kit is for use ONLY in 01T units. See casting comparison illustration to differentiate between 01T and 01J units.
Audi vehicles equipped with 01T transmissions commonly display symptoms such as slipping, pulley and push belt damage, ratio codes, and poor fuel economy. These concerns are often a direct result of loss of control over the primary and secondary pulley sets that interact with the push belt. It is the job of the VSPV valve to govern pulley operation. Deterioration of this pump bore due to continuous valve oscillation results in loss of crucial control pressure to the pulleys. Restore hydraulic control to this high-pressure circuit by reconditioning the bore and installing Sonnax oversized VSPV valve kit 33741B-11K.
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.
Vacuum testing at the port(s) indicated fails to hold the recommended minimum in-Hg, or if wear is visually detected.
