01P FORWARD DRUM LOADED
The 01P Forward Drum (often referred to as the K1 Clutch Drum) is part of the Aisin Warner/VW AG4 family of 4-speed automatic transmissions, specifically designed for front-wheel-drive vehicles with engines mounted longitudinally (inline). It is primarily found in Volkswagen, Audi, Seat, and Skoda vehicles, generally from the early 1990s through the mid-2000s (approx. 1990–2006).

Technical Notes on Fitment
- Transmission Types: 01P (AG4-098), 01M, 01N, 095, 096, 097, 098.
- Variants: The drum is often sold with 4 or 5 friction plates depending on the specific engine torque, with 1996-up models often using 5-plate setups.
- Engine Types: These typically fit 1.4L, 1.6L, 1.8L, 1.9L Diesel, 2.0L, and 2.8L V6 engines.
- Differences: Ensure the replacement drum matches the original in terms of clutch count (5-clutch vs 4-clutch) and whether it uses a Belleville spring (1990–1995 vs 1996-up).
It is highly recommended to verify the specific year, make, model, and engine size to ensure proper fitment, as these transmissions were used across many different configurations.
