Baywindow Bus Automatic Torque Converter Oil Seal

This torque converter oil seal is designed for later Baywindow Buses and all Type 25 (T3) models fitted with 3-speed automatic gearboxes. It also fits VW Type 3 models with automatic transmissions from 1961 to 1973. This critical seal prevents transmission fluid from leaking at the torque converter hub where it engages with the gearbox, ensuring consistent hydraulic pressure and reliable shifting performance.

Manufactured to OEM specifications, the seal measures 42mm inner diameter, 55mm outer diameter, and 7mm thick. Constructed from high-quality, oil- and heat-resistant rubber, it offers long-lasting protection against fluid leaks and wear, even under the demanding conditions of air-cooled and water-cooled VW drivetrains.

Perfect for transmission rebuilds or servicing, this torque converter seal is essential for maintaining smooth, leak-free operation of your automatic gearbox.
