An overheated converter, TCC codes, and/or poor cooler flow are common problems in Honda vehicles equipped with five-speed automatic transmissions. These conditions can be caused by a worn or sticking TC check valve.
The TC check valve ensures converter pressure does not become excessive during TCC apply, release, or partial apply. Repeated stroking of the valve can create casting wear areas over time. Depending upon the specific Honda application, this valve can stroke in one casting or multiple castings that are stacked together. The valve can stick on the ledges of these wear areas or at the edges of the stacked castings.
If the TC check valve sticks in the open position, converter pressure will be reduced. If stuck in the closed position, excess converter pressure can result. Depending upon the wear in the casting bore, the valve may leak, reducing converter pressure or may be prevented from stroking when necessary to reduce excess converter pressure.
Replacing the OE TC check valve with Sonnax TC check valve kit 98892-10K restores correct torque converter pressure and prevents valve hang-up.
