Anatomy of a Transmission: Oil Flow in the Pump-PR-Converter-Cooler Lube Circuits
Gregg Nader
In Jatco/Nissan RE5R05A units, severe wear of the TC pressure regulator valve bore results in leakage of converter release/lube/cooler oil pressure that compromises unit durability, resulting in damaged TCC linings, overheated converters and lube failures. Sonnax TC regulator valve kit 63741-17K salvages these valve bodies.
Tool kit F-63741-TL13 can also be used for valve kit 63741-13K
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.
