The integration of Subaru drivetrains into Volkswagen (VW) vehicles is a popular modification among automotive enthusiasts. These conversions merge the iconic design of VW vehicles with the reliable and powerful performance of Subaru engines.
However, executing a seamless conversion requires critical components, and one often overlooked yet essential part is the Subaru transmission cap.
This transmission cap is specifically designed to seal the rear of the nose cone housing in Subaru 5-speed manual transmissions during conversions.
Its importance in maintaining the functionality and reliability of your conversion cannot be overstated. In this blog, we’ll explore why the transmission cap is indispensable and its specific role in VW-Subaru conversions.
A transmission cap is a component specifically designed to seal the rear of the nose cone housing in a transmission. In Subaru-to-VW conversions, the cap is used during the process of converting a Subaru transmission from AWD to 2WD.
By sealing the exposed opening created when the AWD components are removed, the transmission cap prevents contamination and maintains the structural integrity of the system.
The Subaru transmission cap offered by Specialised Parts is precision-engineered for Subaru 5-speed manual transmissions and includes a cap cover plate to ensure a reliable seal.
The transmission cap plays several critical roles in ensuring a smooth and reliable conversion:
When converting a Subaru transmission from AWD to 2WD, removing the rear extension housing exposes internal components. The transmission cap seals this opening, protecting the transmission from dirt, debris, and moisture.
A well-fitted cap ensures that transmission fluid remains contained, preventing leaks. This is essential for proper lubrication of gears and bearings, which minimizes wear and ensures smooth operation.
By capping off the transmission, the cap helps maintain the structural stability of the nose cone housing. This ensures the longevity of the transmission, especially under the unique stresses of a hybrid VW-Subaru drivetrain.
The cap simplifies the AWD-to-2WD conversion process, allowing enthusiasts and professionals to achieve a seamless drivetrain integration with minimal hassle.
The transmission cap from Specialised Parts is designed with the following features to meet the demands of VW-Subaru conversions:
Proper installation of the transmission cap is crucial for optimal performance. Here’s a step-by-step guide:
Clean the nose cone housing thoroughly to remove any dirt, debris, or old sealant. Inspect the area for wear or damage.
Use a high-quality gasket sealant on the mating surface of the nose cone housing. This helps create a leak-proof seal.
Position the transmission cap carefully over the housing. Ensure it aligns properly to avoid gaps or misalignment.
Use the appropriate fasteners to secure the cap cover plate in place. Tighten the screws evenly to ensure a snug fit.
After installation, inspect the transmission for any signs of leaks. Top off the transmission fluid if necessary.
