Torque Specifications:
Essential torque values for all fasteners, critical for correct assembly.
Engine Compatibility:
Varies by vehicle model listed (e.g., V8 petrol, diesel variants common in these models). Specific engine details not in manual description, but R380 typically paired with 4.0L/4.6L V8 petrol and 2.5L TD/TDI diesel engines.
Gearbox Performance Impact:
The R380's design influences the vehicle's overall performance, shift feel, and durability under load.
Engine Fuel Types:
The manual is applicable to vehicles with both petrol (gasoline) and diesel engines, meaning the R380 gearbox needs to be understood in the context of different torque outputs and operational characteristics.
Vehicle Platform Compatibility:
Range Rover Classic, Discovery 1, Defender, Discovery 2 platforms which share common chassis and drivetrain architectures.
Gearbox Weight:
The R380 gearbox is a substantial unit, weighing approximately 70-80 kg (154-176 lbs) when filled with fluid. (Exact weight may vary).
Overall Vehicle Weight:
The manual's focus on the gearbox implies understanding its role in the vehicle's overall weight distribution and driveline load capacity.
Gearbox Oil Change:
Specific intervals are detailed within the manual, typically around 30,000-60,000 miles or as per manufacturer recommendations for these vehicles. (Exact figures in manual).
Clutch Release Bearing Inspection:
Guidance on inspecting and potentially replacing the clutch release bearing during gearbox overhaul.
Gearbox Oil Type:
Likely requires specific manual transmission fluid (MTF) meeting API GL-4 or GL-5 specifications, with viscosity recommendations (e.g., 75W-90 or 80W-90) detailed in the manual.
Clutch Fluid:
While not a gearbox fluid, clutch hydraulic fluid specifications (e.g., DOT 3 or DOT 4 brake fluid) are often relevant during gearbox removal/installation and should be checked in the applicable vehicle service manual.
Gearbox Oil Capacity:
The manual will specify the correct fluid capacity for the R380 gearbox, crucial for proper lubrication and cooling. Typically around 2.2 - 2.5 liters.
Common R380 Problems:
Potential issues include worn synchromesh rings, input shaft seal leaks, selector mechanism wear, and bearing noise. Manual provides diagnostic and repair guidance.
Shift Lever Issues:
Wear in the remote gear selector housing or linkage can lead to sloppy shifting or difficulty engaging gears.
Input Shaft Bearing Wear:
Wear in the input shaft pilot bearing or main shaft bearings can cause noise and shifting issues.
Selector Mechanism Wear:
Wear in the external selector housing and internal shift rails can cause a vague or difficult gear selection.
Routine Maintenance:
Gearbox oil checks and changes, clutch system checks (though clutch itself may have separate manual coverage).
Land Rover Legacy:
Renowned for robust off-road capabilities and durable transmissions.
R380 Gearbox Introduction:
The R380 gearbox was a significant development in Land Rover's manual transmission history, known for its strength and improved shift quality over predecessors.
R380 Applications:
The R380 was a key transmission for Land Rover's larger vehicles in the latter half of the 1990s and early 2000s, replacing the older R380 and its predecessors.
Vehicle Production Period:
Models covered range from 1995 production onwards, encompassing significant portions of the '90s and early 2000s.
