NO TOOLING REQUIRED
Vehicles equipped with 1st and 2nd design Jatco/Nissan RE5R05A valve bodies may have TCC concerns such as lockup shudder, premature or bumpy apply, slippage and/or a burnt converter. These issues can be caused by wear in the TCC control sleeve which allows apply pressure leakage.
Vehicles equipped with Jatco/Nissan RE7R01A, JR710E, JR711E and JR712E transmissions may display harsh downshifts caused by wear and leakage in the Low brake switch boost sleeve. All above issues can be solved by installing Sonnax TCC control valve kit/Low brake switch boost valve kit 63741-05K into the appropriate bore.
