O Ring

About this product

The O Ring (#90301-21012), a critical Drive-Chassis part within the Valve Body & Oil Strainer system of automatic transmissions, is fundamental to maintaining the system's integrity. Its primary role is to create a pressure and fluid seal between the interconnected parts of the transmission system. The O Ring (#90301-21012) operates by being compressed between the parts, creating a tight seal that prevents fluid or pressure leakage. Over time, these O Ring (#90301-21012)s can wear out, potentially leading to leaks and loss of system pressure, which can result in transmission malfunctions or failures. Replacement with a genuine Toyota part is vital for compatibility and functionality. Genuine parts carry the assurance of being backed by Toyota's parts warranty. In contributing to the overall system efficiency and safety, the O Ring (#90301-21012)'s role in maintaining the proper level of fluid and pressure within the transmission is crucial. Without it, the system could fail, posing significant safety risks.
