Find the right Discovery 4 transmission and drivetrain parts

Transmission and driveline repairs divide into the automatic gearbox, transfer box, differentials, propshafts and the drive components running out to the wheels. Identifying the affected section first makes it easier to find the correct parts and service items.

Check transmission and drivetrain fitment before ordering

Discovery 4 transmission and driveline components can differ by engine, gearbox specification, axle position and vehicle production point. Match the original part number and product fitment information rather than relying on the general component name alone.

Gearbox and driveline specification
Confirm the gearbox, transfer box or differential fitted before ordering internal parts, service kits, seals or mounts.
Front, rear and side
Check front or rear position and left-hand or right-hand fitment for propshafts, driveshafts, seals and differential components.
Complete assembly or service part
Confirm whether the repair requires a complete shaft, differential or gearbox component, or an individual bearing, seal, joint or mounting part.
Part number and production point
Use the original reference together with any stated model-year or VIN split shown on the product page.

Genuine, OEM and aftermarket drivetrain parts

Individual product pages identify the brand or quality level where that information is available. Use the stated brand, part number, transmission specification, fitting position and included parts to compare drivetrain components.

Part type How it is shown on Twinwoods 4x4
Genuine Land Rover Genuine parts are identified as Genuine Land Rover where that status is confirmed on the product page.
OEM or OE-supplier OEM and OE-supplier parts are identified where the supplier or product information supports that claim.
