Transmission & Drivetrain Parts
Discovery 4 transmission and drivetrain parts for automatic gearbox servicing, transfer box repairs and maintaining drive through the differentials, propshafts and driveshafts.
Start with the transmission or driveline section being repaired, then check the product page for original part number, gearbox or transfer box specification, front or rear position, left-hand or right-hand fitment and any model-year or VIN split.
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.
| Job | Best place to start | Check before ordering |
|---|---|---|
| Automatic gearbox servicing and repairs | Service kits, filters, sumps, seals, mounts, cooling pipes and gearbox components | Gearbox specification, engine, sump or filter design, fluid requirement and original part number |
| Transfer box repairs | Seals, bearings, flanges, mounts, actuators and service components | Transfer box specification, fitting position, electrical connections and original component reference |
| Front and rear differential repairs | Differential assemblies, bearings, seals, flanges, bushes and mounting parts | Front or rear fitment, differential specification, ratio where relevant and original part number |
| Propshaft and coupling replacement | Front and rear propshafts, joints, couplings, centre bearings and fixings | Front or rear position, overall specification, flange connections and vehicle production point |
| Driveshaft and CV joint repairs | Driveshafts, CV joints, boots, seals, retaining parts and related fixings | Front or rear axle, left-hand or right-hand side, joint specification and original part number |
| Transmission oil and fluid servicing | ATF and steering fluid, gear oil and transmission service kits | Transmission, transfer box or differential specification, required fluid and service quantity |
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.
Confirm the gearbox, transfer box or differential fitted before ordering internal parts, service kits, seals or mounts.
Check front or rear position and left-hand or right-hand fitment for propshafts, driveshafts, seals and differential components.
Confirm whether the repair requires a complete shaft, differential or gearbox component, or an individual bearing, seal, joint or mounting part.
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. |
| Aftermarket replacement | Aftermarket parts cover selected replacement, service and repair components where Genuine or OEM supply is not required or not stated. |
