Description

Volkswagen 1.8T AGU 6-Speed Manual Gearbox

The Volkswagen 1.8T AGU 6-Speed Manual Gearbox restores your turbo-charged VW’s precise factory shifting. This OEM-spec transaxle bolts directly to the AGU engine’s bellhousing and integrates with the stock cable linkage—no adapters or modifications—delivering smooth, durable gear engagement under boost.

Construction & Durability

• Precision Casting: Housing molded to exact Volkswagen factory dimensions for a seamless fit.

• Heat-Treated Internals: Gears, shafts, and synchronizer rings treated for enhanced wear resistance under turbo torque.

• CNC Machining: All gear teeth and synchro cones machined to tight tolerances for consistent engagement.

Performance Benefits

1. Sharp, Positive Shifts
   Short, well-defined throws eliminate false neutrals—even under boost.

2. Optimized Gear Spread
   Six speeds keep the AGU engine in its peak power band for brisk acceleration and fuel-efficient cruising.

3. Reduced NVH
   New bearings and seals dampen noise and vibration, ensuring a refined driving experience.

   Engineered to withstand high mileage and the demands of a turbocharged powerplant.

Installation & Maintenance Tips

• Pre-Install Prep: Replace clutch kit, pilot and throw-out bearings, and rear main seal to prevent leaks.

• Alignment: Use an input-shaft alignment tool for exact concentric fit with the engine.

• Break-In: Drive gently for the first 500 km to allow synchronizers to properly bed in.

• Service Interval: Change gearbox oil every 60 000 km with VW-approved 75W-85 GL-4 fluid.
