Range Rover Sport L320 Automatic Transmission Oil Pan With Filter Set BMW 6HP LR007474

Get Range Rover Sport L320 Automatic Transmission Oil Pan With Filter Set 6HP LR007474 in Kenya

The Automatic Transmission Oil Pan with Filter Set (6HP), part number LR007474, is a complete transmission service component designed for use in vehicles equipped with ZF 6HP series automatic transmissions. This assembly combines an oil pan (also called a sump) and an integrated transmission fluid filter, specifically engineered to protect and enhance the performance of the gearbox.

Found in a wide range of premium vehicles such as Land Rover, BMW, Jaguar, and others, the ZF 6HP transmission is renowned for its smooth shifting, performance, and efficiency. Maintaining this complex system requires a reliable oil pan and filter assembly like LR007474, which ensures consistent fluid flow, debris filtration, and proper sealing of the transmission’s lower section.

1. What Is the Automatic Transmission Oil Pan with Filter Set LR007474?

The LR007474 is a combination oil pan and fluid filter assembly that serves both as a reservoir for transmission fluid and as the primary filtration unit in ZF’s 6-speed automatic transmission (6HP series). Unlike traditional designs where the filter and pan are separate, the LR007474 integrates both components into a single unit, streamlining installation and improving reliability.

This design reduces the number of gaskets and connection points, which in turn lowers the risk of leaks or failure.

2. Key Components of LR007474 Assembly

The LR007474 assembly includes several important elements:

a) Transmission Oil Pan (Sump)

• Constructed from high-grade plastic or composite materials, it is designed to be lightweight, corrosion-resistant, and heat-tolerant.

• Serves as a fluid reservoir and mounting point for the transmission filter and magnets.

b) Integrated Transmission Fluid Filter

• Built directly into the pan.

• Filters out debris, clutch particles, and contaminants from the transmission fluid.

• Designed with fine mesh media to trap small particles while maintaining proper fluid flow.

c) Sealing Gasket

• Often molded directly onto the pan or provided as a separate rubber gasket.

• Ensures a leak-proof seal between the pan and transmission housing.

d) Mounting Hardware

• Typically includes a set of screws or bolts for securing the assembly to the transmission body.

e) Drain Plug (Optional)

• Some variants may include a built-in drain plug to allow for easier fluid changes without removing the entire pan.

3. Functionality and Operation

The LR007474 assembly performs several critical roles in transmission operation:

• Reservoir: Stores a portion of the transmission fluid that lubricates and cools the moving parts.

• Filtration: The built-in filter captures metallic shavings, clutch dust, and other particles that could otherwise clog valves or damage internal components.

• Sealing: Prevents transmission fluid leaks and ensures consistent fluid pressure.

• Heat Dissipation: Although made of composite, the pan assists in managing fluid temperature by dispersing heat from the fluid.

4. Why LR007474 Is Essential for ZF 6HP Transmissions

The ZF 6HP series is a high-performance, electronically controlled automatic transmission. It requires clean, properly pressurized fluid to operate its hydraulic circuits, torque converter, and clutches. The LR007474 assembly is designed specifically to:

• Match the transmission housing precisely, reducing installation errors.

• Maintain optimal fluid pressure and cleanliness, preventing overheating or slippage.

• Ensure compatibility with transmission control strategies, helping achieve smooth and efficient gear changes.

5. Advantages of the Integrated Pan & Filter Design

• Ease of Maintenance: Replacing both the pan and filter in one unit saves time and eliminates compatibility issues.

• Leak Prevention: Fewer joints and gaskets reduce the chances of fluid leakage.

• Durability: Made from impact-resistant, heat-tolerant composite materials that resist warping and corrosion.

• Precise Fitment: OEM design guarantees perfect alignment with bolt holes and fluid passages.

• Improved Longevity: A clean transmission system prolongs the life of solenoids, valve bodies, and clutch packs.

6. Symptoms of a Worn or Clogged Transmission Filter

If the LR007474 assembly is clogged or worn, the transmission may begin to show signs of distress:

1. Delayed Gear Engagement – Fluid flow restriction can cause delayed shifts into drive or reverse.

2. Slipping Gears – Contaminated or insufficient fluid may prevent clutches from engaging properly.

3. Overheating Transmission – A clogged filter reduces fluid circulation, leading to high operating temperatures.

4. Harsh or Erratic Shifting – Dirty fluid or clogged filters can interfere with the operation of the valve body.

5. Unusual Noises – Whining or grinding sounds may indicate a failing pump caused by fluid starvation.

7. Replacement Interval and Service Recommendations

ZF recommends changing the transmission fluid and filter every 80,000 to 100,000 km under normal conditions. For vehicles operating under heavy load, towing, or extreme temperatures, more frequent servicing may be advisable.

Replacing the LR007474 assembly during fluid service ensures that old contaminants are not circulated back into the clean transmission fluid.

8. How to Replace the LR007474 Transmission Oil Pan and Filter Set

Tools and Materials Needed:

• Transmission fluid compatible with ZF 6HP (e.g., ZF Lifeguard 6)

• LR007474 oil pan and filter assembly

• Torque wrench

• Drain pan

• Socket set

• Jack and jack stands or lift

• Funnel and fluid pump

Basic Steps:

1. Raise the Vehicle: Ensure it’s safely supported on jack stands or a lift.

2. Drain the Old Fluid: If the pan has a drain plug, remove it. If not, prepare for full pan removal.

3. Remove Bolts: Unscrew all mounting bolts and carefully lower the pan.

4. Clean Mating Surface: Wipe away old gasket residue and debris from the transmission housing.

5. Install New Pan: Position the LR007474 assembly and hand-tighten all bolts.

6. Torque Bolts to Specification: Use a cross pattern to tighten bolts evenly.

7. Refill Fluid: Add the correct amount of ZF 6HP-approved transmission fluid through the fill port.

8. Check for Leaks and Re-Test Fluid Level: Start the engine, run through gears, and check fluid level once the transmission is at operating temperature.

9. Compatibility and Applications

The LR007474 assembly is used in various vehicles equipped with ZF 6HP26 or 6HP28 transmissions. These include:

• Land Rover: Range Rover Sport, Discovery 3/4

• Jaguar: XJ, XF, XK

• BMW: E60, E70, E90 (specific models)

• Others: Some Audi, Bentley, and Ford models

Always verify fitment using your VIN or consulting a parts specialist before purchase.
