Gearbox Drain Plug (Filler Plug)

This gearbox oil filler and drain plug is a direct replacement sealing plug used on the side of the gearbox to allow the filling or draining of transmission oil. Over time, original plugs can become rounded, damaged, or seized, making routine gearbox servicing difficult and increasing the risk of oil leaks. Replacing the plug ensures a secure seal and allows proper maintenance of gearbox oil levels.

Manufactured to the correct M24 x 1.5 thread size, this plug fits a wide range of Volkswagen manual gearboxes across multiple model generations. It installs directly into the factory threaded opening and is suitable for both filler and drain positions where applicable. Ideal for routine servicing, gearbox rebuilds, or replacing missing or damaged plugs.
