Automatic Transmission Pan Gaskets

The transmission pan gasket plays a vital role in sealing the area between the transmission case and the fluid pan. Its main function is to prevent automatic transmission fluid (ATF) from leaking during normal operation, maintenance, or changes in temperature. While it may not always get the attention it deserves, using the wrong gasket or installing it incorrectly can disrupt internal pressure, cause fluid leaks, and potentially damage or ruin the transmission.

At Sun Transmissions, we carry an extensive selection of transmission pan gaskets that fit a broad range of automatic transmission systems. Every gasket we supply is built to meet or surpass OEM standards, delivering reliable sealing whether you're working with original equipment or aftermarket pans.

Any time the transmission pan is taken off—be it for a fluid and filter change, solenoid servicing, or a full rebuild— the gasket should be replaced. Our detailed catalog makes it easy to choose the right gasket, using unit codes, OEM part numbers, and pan compatibility details to help transmission technicians avoid costly rework and keep things running smoothly.
