FAQ
What vehicles are compatible with the NO‑13 seal?
The NO‑13 seal is compatible with many automatic transmissions and drive axles that specify a painted transmission seal of similar dimensions. Refer to your vehicle’s service manual or contact our support team with the make and model for confirmation.
How do I install the seal correctly?
Begin by cleaning the housing surface thoroughly, removing any old seal residue. Apply a thin layer of transmission fluid to the seal’s outer edge, then gently press it into place using a seal driver or a suitable tool to avoid deformation. Ensure the seal sits evenly around the bore before reassembling the transmission.
Is the painted coating safe for all transmission fluids?
Yes, the paint used on the ATP seal is formulated to be chemically inert with standard automatic transmission fluids, ATF, and gear oils, providing long‑term protection without degradation.
Can I use this seal for a manual transmission?
While the seal is primarily designed for automatic transmissions, it can be used in manual applications where the dimensions and material requirements match. Verify the fit before installation.
What is the warranty on this product?
ATP offers a one‑year limited warranty covering manufacturing defects. If the seal fails due to material or workmanship issues within this period, we will provide a replacement or refund.
