Description

The Sonnax O-Ringed TC Check Valve Kit (98892-29K) is engineered to resolve common issues in Honda and Acura 4-speed and 5-speed transmissions. It addresses problems stemming from overheated converter fluid and poor performance of the converter and cooler oil circuits. By restoring correct torque converter pressure, this kit helps prevent overheating and valve hang-up, ensuring smoother operation. This kit is specifically designed as an o-ringed replacement for the standard TC check valve, enhancing its sealing capabilities and longevity. It is applicable to various Honda/Acura 4-speed (3-shaft) and 5-speed transmissions, including those with transmission codes such as M7ZA, B7ZA, BGFA, MGFA, B7VA, and M7WA. While it fits several models, it's important to note that valve body appearance and the location of the TC check valve bore can vary between different models and transmission types.
