✓Direct replacement for Toyota OEM 35178-30010 (3517830010). Cross-references with 35178-02010 (3517802010), 35178-50010 (3517850010), and 90341-10078 (9034110078). Dimensions: 12mm / 0.47in ID, 18mm / 0.71in OD, 1.5mm / 0.06in thickness. 15-pack — enough for 15 transmission services.
✓Important: this is the transmission drain plug crush washer (35178-30010) — different from the engine oil drain plug washer (90430-12031) which has a 21mm OD. Toyota uses different size washers for different drain points. Always verify your OEM washer part number before ordering.
✓Made from steel matching the original Toyota factory specification. Steel crush washers compress under torque to fill microscopic surface imperfections between the drain plug and transmission case, creating a tight, leak-free seal. Compatible with Toyota WS (World Standard), T-IV, and Type IV automatic transmission fluids.
✓Crush washers are single-use components — Toyota recommends replacing the gasket at every transmission fluid service. Reusing an old crush washer is one of the most common causes of transmission fluid leaks after service. A fresh washer gives a proper seal every time. Torque the drain plug to Toyota specification of 27 ft-lbs (37 Nm).
