Purpose and technical specifications

The described automatic transmission has been designed to work with the 4.4 V8 petrol engine in the Range Rover L322 model. The transmission design is adapted to the high torque of the V8 unit, ensuring smooth power delivery and stable operation under typical operating conditions for this model – both on-road and off-road.

As a result, the transmission maintains the correct engine speed, which translates into a smooth, harmonious ride.

Benefits of using an original automatic transmission

Using a factory-spec automatic transmission dedicated to the Range Rover L322 4.4 V8 ensures compliance with the vehicle's original parameters. Proper matching with the drivetrain, control systems, and electronics minimizes the risk of compatibility issues and reduces the need for additional modifications.

Key advantages of this solution include:

• Consistency with factory software controlling the transmission and engine operation.
• Predictable behavior during gear changes, consistent with the characteristics of the L322 model.
• Ability to retain original driving modes and drivetrain logic.
• Reduced risk of incorrect gear selection compared to aftermarket replacements of uncertain origin.

Condition, verification, and selection based on technical data

The offered transmission comes from dismantling and is a used component, which allows for a significant reduction in repair costs compared to purchasing a new unit. Before installation, a standard service procedure is recommended, including checking for leaks, verifying the oil condition, and – if necessary – replacing consumables in accordance with the vehicle manufacturer's recommendations.

To ensure correct selection, it is worth using the manufacturer's markings, OEM part numbers, and interchangeable numbers, as well as vehicle data (model, year, engine type). This approach reduces the risk of error and speeds up the process of matching the transmission to a specific Range Rover configuration.
