Original MANN-FILTER Oil filter HD 45/5 – Transmission filter – For Passenger Cars and Utility Vehicles

Product Overview

The MANN‑FILTER Oil Filter HD 45/5 is a high‑performance transmission filter designed specifically for passenger cars and utility vehicles equipped with automatic transmissions. It delivers reliable protection against contaminants that can compromise hydraulic fluid quality, ensuring smooth operation of the transmission system.

Key Features

• Advanced Filtration Technology: Utilises a multi‑layer filtration media that captures particles as small as 0.5 µm, preventing wear on internal components.
• Optimised Flow Rate: Engineered to maintain optimal hydraulic pressure while filtering, reducing the risk of transmission stall or overheating.
• Durable Construction: Made from high‑grade polypropylene and reinforced with a stainless steel housing for long service life under demanding conditions.
• Easy Installation: Features a standard 45 mm diameter fitting compatible with most automatic transmission housings, allowing quick replacement without specialised tools.
• Compatibility: Suitable for a wide range of vehicle models including many European passenger cars and light commercial vehicles that use the HD 45/5 specification.

Performance Benefits

The HD 45/5 filter is engineered to maintain the integrity of hydraulic fluid, which directly influences transmission longevity. By trapping contaminants early, it reduces:

• Wear on gear teeth and bearings, extending component life.
• Heat buildup caused by friction from dirty fluid, improving thermal stability.
• Transmission failure rates associated with clogged or degraded hydraulic systems.

Installation Guide

1. Locate the transmission filter housing on your vehicle’s automatic gearbox.
2. Disconnect the hydraulic fluid reservoir cap and drain any excess fluid if necessary.
3. Unscrew the old filter using a suitable wrench, taking care not to damage the housing seal.
4. Remove any debris from the housing opening before inserting the new HD 45/5 filter.
5. Screw the filter in place until it is snug; do not overtighten to avoid damaging the gasket.
6. Re‑attach the hydraulic reservoir cap and refill with fresh transmission fluid if required.
7. Start the engine, allow the transmission to warm up, and check for leaks or abnormal noises.

Maintenance Tips

• Replace the filter at every scheduled transmission service interval, typically every 30,000–60,000 km depending on driving conditions.
• Inspect the filter housing gasket for wear; replace if cracked or brittle to prevent fluid leaks.
• Avoid using incompatible filters that do not meet the HD 45/5 standard, as they may compromise filtration efficiency.
