Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits
Gregg Nader
Listed Nissan/Jatco units often have trouble with slipping, delayed engagement and/or reduced pump output. Excess wear of the pump flow control valve allows crucial pressure loss that can lead to these symptoms. Installing Sonnax pump flow control valve 33510N-02 restores critical clearances for enhanced hydraulic control and renewed pump operation.
If bore wear is discovered, Sonnax oversized pump flow control valve 33510N-01 is available.
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.
