T4 Transporter Automatic Gearbox Oil Strainer Seal

This round rubber oil strainer seal is used to seal the gearbox oil strainer to the valve body inside 4-speed automatic gearboxes fitted to Volkswagen Transporter T4 models. The seal plays a critical role in ensuring correct oil flow within the transmission by preventing internal leaks between the strainer and valve body. A worn, flattened, or hardened seal can cause pressure loss, poor shifting performance, and premature gearbox wear.

Manufactured from durable, oil-resistant rubber, this seal provides a tight, reliable fit and is an essential replacement whenever the oil strainer is removed—such as during routine automatic transmission servicing or repairs. Replacing this seal helps maintain correct hydraulic pressure, clean oil circulation, and smooth, consistent gear changes.

Designed specifically for 4-speed automatic gearboxes, this seal does not fit gearbox codes CGK, CGH, CFZ, or CGA.
