External signs:
*Toyota Logo and Part Number: Genuine Toyota automatic transmission filters are clearly engraved with the Toyota logo and the correct part number.
*Color and Material: Genuine filters are light gray in color and made of high quality materials. Counterfeits may have a different color or be made from cheaper materials.
* O-ring: Genuine filters have a purple O-ring that seals tightly to the transmission flange. Counterfeits may have a black or other colored O-ring which may not provide a proper seal.
* Size and Shape: Genuine filters are the correct size and shape for your specific transmission model. Counterfeits may vary slightly in size and shape, which may result in installation issues or leaks.
*Weight: Genuine filters are usually slightly heavier than counterfeits due to the high quality materials used.
Internal structure:
*Filter Media: Genuine filters have a multi-layer filter media that effectively removes particles and debris from transmission fluid. Counterfeits may have thinner or less layered filter media, reducing its effectiveness.
* Check valve: Genuine filters have a check valve that prevents transmission fluid from flowing back out of the automatic transmission while the vehicle is parked. Counterfeits may have a less effective check valve or no check valve at all.
Package:
*Box: Genuine Toyota filters are supplied in Toyota branded boxes. Counterfeits may come in boxes or other types of packaging.
*Label: Genuine filters have a label with detailed information such as part number, vehicle model and lot number. Counterfeits may have inaccurate or insufficient information.
Other signs:
* Price: Original Toyota filters are usually more expensive than fakes.
*Place of Purchase: Genuine filters should be purchased from an authorized Toyota dealer or reputable supplier. Buying from unknown or illegal sellers increases the risk of buying a counterfeit.
*Install and check: During installation, check that the filter is sealed correctly and that there are no transmission fluid leaks. If you find any problems, you may have purchased a counterfeit product.
