Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits
Gregg Nader
Severe wear of the TC pressure regulator valve bore in VW/Audi 09A and Jatco JF506E units results in leakage of converter release/lube/cooler oil pressure that compromises unit durability, resulting in damaged TCC linings, overheated converters and lube failures. Reconditioning the bore and installing Sonnax TC pressure regulator valve kit 122892-10K restores the hydraulic integrity of the circuit allowing you to salvage these valve bodies.
This kit also services Jatco FP series; Ford JF506E, FPH; Jaguar JF506E, FPD; Mazda JA5A-EL FPF1/FPF2; Rover JF506E, FPO; Nissan ZY units.
