Excessive wear at lockup control valve spools and bore lands allows cross leaks between normally isolated circuits resulting in lost ATF pressure and uncontrolled flow to the sump.
Installation of the Sonnax oversized lockup control valve kit restores critical hydraulic circuit clearances and OE performance.
Honda/Acura 4-speed units are infamous for TCC lockup issues in both full lockup and slip mode. These units also are known to frequently overheat either the torque converter alone or the entire transmission. These issues are caused by wear at valve spools and bore lands that allow ATF to leak away from critical hydraulic circuits. Installing the Sonnax oversized lockup control valve kit 98892-17K re-establishes hydraulic integrity to control circuits and restores OE function.
