An overheated converter, TCC codes, and/or poor cooler flow are common problems in Honda/Acura vehicles equipped with 4-speed, 3-shaft and 5-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. Over time, repeated stroking of the valve creates wear areas in the casting. Depending upon specific Honda/Acura application, this valve can stroke in one casting or between multiple castings stacked together. The valve often sticks 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. Severe bore wear allows critical pressure to exhaust, resulting in high or low converter pressure. Prevent valve hang-up and recover hydraulic control by installing Sonnax TC check valve kit 98892-06K.

This kit fits several Honda/Acura 4-speed, 3-shaft and 5-speed models. However, model to model, the appearance of valve bodies and the location of the TC check valve bore may vary. The BVGA '03-'05, 3.5L Pilot model is illustrated here. See Honda/Acura 98892-06K application chart for a detailed guide.
In addition, certain models require a different style TC check valve. Refer to application chart for TC check valve 98892-10K or 98892-32K if the model you are working on does not appear in 98892-06K application chart.
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.
