Original MANN-FILTER Oil filter W 1374/2 – Transmission filter – For Passenger Cars and Utility Vehicles

MANN‑FILTER W 1374/2 Transmission Oil Filter

The MANN‑FILTER W 1374/2 is a high‑performance transmission oil filter designed for passenger cars and utility vehicles equipped with automatic transmissions. It delivers superior protection against contaminants, ensuring optimal operation of the hydraulic system that powers gear changes.

Key Features

• Precision Filtration: The filter employs a multi‑layer media construction that captures particles as small as 0.5 µm, preventing wear on gears and seals.
• Durable Construction: Made from high‑quality polypropylene housing, the filter resists corrosion and maintains structural integrity under pressure variations typical of automatic transmissions.
• Easy Installation: The spin‑on design allows for quick replacement without special tools. The gasket ensures a leak‑free seal during operation.
• Extended Service Life: Designed to last through the full service interval recommended by vehicle manufacturers, reducing maintenance frequency.
• Compatibility: Fits a wide range of models from compact cars to light commercial vehicles that use automatic gearboxes. The filter is engineered to match OEM specifications for fluid flow and pressure drop.

Installation Guidelines

1. Park the vehicle on a level surface and engage the parking brake.
2. Locate the transmission filter housing; it is typically positioned near the rear of the gearbox.
3. Drain any residual fluid if required by the manufacturer’s procedure.
4. Unscrew the old filter using an appropriate wrench or by hand, depending on the model.
5. Remove the gasket and clean the mounting surface to ensure a proper seal.
6. Place the new MANN‑FILTER W 1374/2 into the housing, aligning it with the flow direction indicated by the arrow on the filter body.
7. Screw the filter in place until snug; avoid overtightening which could damage the gasket.
8. Refill the transmission with the recommended fluid type and capacity.
9. Start the engine and allow the system to circulate for a few minutes, checking for leaks.
