What the AI looks for in Automotive Replacement Transmission Filter & Gasket Kits

Transmission code match: The kit listing should name the transmission model code, and both the filter and the gasket bolt pattern must match your pan. Pan shapes differ between transmission versions, even within one vehicle line.
Gasket material: Prefer a molded rubber gasket or a rubber-coated steel-core gasket over plain cork where your application offers one. Cork compresses, splits and leaks if overtightened, while molded and steel-core gaskets hold torque better.
Complete kit: Look for a filter, a pan gasket and the neck seal or O-ring; some kits also include a magnet or pan bolts. Missing small seals forces a second trip and often leads to reusing worn parts.
Integrated-filter pans: If the filter is molded into the pan, buy the pan assembly with its gasket instead of a separate filter kit. A loose filter cannot be fitted to these designs.
Pan bolt torque: Tighten pan bolts to the factory torque spec in a crisscross pattern. Overtightening crushes the gasket and distorts stamped pans, which is the most common cause of leaks after a service.

Kits that do not list the transmission code
Adding RTV to a gasket the maker specifies to install dry
Reusing a cork gasket
Kits without the neck seal when your old seal is stuck in the valve body (pull it out before fitting the new filter)

Some molded rubber or steel-core gaskets are sold as reusable if undamaged, but cork and paper gaskets are not. When in doubt, replace it.
