View full detailsCategory Overview
Every Land Rover and Range Rover uses a two-part driveline: a main gearbox that handles gear ratios and torque delivery, and a transfer box that splits drive between the front and rear axles for the brand's 4x4 traction. Both are serviceable assemblies and both are made up of parts that wear, leak, or fail individually long before the unit itself needs replacing. This collection covers the seals, bearings, synchros, gaskets, fluids, and rebuild components for the gearboxes and transfer cases fitted across the Defender, Discovery, Range Rover, Freelander, and Series ranges.
For most owners the right approach is component replacement, not unit replacement. A leaking output seal, a worn bearing, or contaminated fluid are repairable faults. Knowing which fault you have, and which part fits your specific gearbox or transfer case, is the difference between a straightforward fix and an expensive misdiagnosis.
ZF Automatic GearboxesModern Land Rover and Range Rover models run almost exclusively on ZF automatic transmissions. The ZF 6HP26 sits in the Range Rover L322, Range Rover Sport L320, and Discovery 3 and 4. The ZF 8HP series followed it across the Range Rover L405, Range Rover Sport L494, Range Rover L460, Range Rover Sport L461, and Discovery 5.
These gearboxes are precision hydraulic-mechatronic units. The valve body, torque converter, and electronic control module are the most common failure points, usually triggered by degraded fluid rather than mechanical wear. Symptoms such as delayed engagement, gear hunting, or harsh shifting on a warm gearbox typically point to valve body or fluid condition, not to a failing transmission.
For service work on these units, ZF specifies ZF Lifeguard Fluid 6 (6HP series) or ZF Lifeguard Fluid 8 (8HP series). The two fluids are not interchangeable. ZF's official position on 8HP service intervals is "fill for life", but independent transmission specialists across Europe recommend a precautionary fluid and pan-filter service at around 80,000 to 120,000 km on vehicles used for towing, urban driving, or high-mileage motorway work. For the technical detail on fluid specifications and service requirements, ZF Aftermarket publishes its own transmission oil reference guide.
Confirm the ZF gearbox code on your vehicle before ordering fluid or service kits. ZF Lifeguard Fluid 6 and Lifeguard Fluid 8 are different specifications, and using the wrong grade is the most common cause of valve body wear after a DIY service.
Manual gearboxes are less common on current production but are still the dominant powertrain across the Classic Defender, early Discovery, Freelander 1, and the Series range. The R380 was the long-running five-speed unit fitted to the Discovery 1 (post-200Tdi production), Discovery 2, and Classic Defender from the 300Tdi through to early Td5. The MT82 six-speed replaced it on the Defender 2.4 and 2.2 TDCi Puma. Earlier production used the LT77 (Discovery 1 200Tdi era) and the LT76 and LT95 on Series 2/3 vehicles.
These units fail in predictable ways. Synchroniser rings on second and third gear wear first. Input shaft and lay shaft bearings degrade with age and oil contamination. Selector linkages and detent springs cause the symptoms most often misdiagnosed as a gearbox fault. Reverse idler gear chatter is common on R380 units past 240,000 km.
For most manual-gearbox owners, parts-level repair is straightforward and rebuild kits are available for the R380, LT77, and MT82. Specific Freelander 1 parts (IB5 manual) sit under the Freelander 1 collection. Series 2/3 gearbox parts have their own fitment requirements covered under the Series 2 and 3 collection.
Transfer BoxesThe transfer box carries as much load as the gearbox and is often the part that goes ignored until it fails. The LT230 is the dominant transfer case across the Classic Defender, Discovery 1, Discovery 2, Range Rover Classic, and P38. It uses gear-drive between input and output shafts and a chain-drive system to the front output. The Discovery 3 and Discovery 4 use a chain-drive Magna Steyr unit with an electronic shift system. Modern Range Rover and Range Rover Sport models on the L405, L494, L460, and L461 platforms use a ZF-integrated transfer case as part of the transmission assembly.
Common failures are output shaft seal leaks, chain stretch on chain-drive units (Magna Steyr and modern ZF), viscous coupling failure on units fitted to early Discovery 2 and Range Rover P38, and selector motor failure on electronic-shift cases.
Transfer box fluid is not the same specification as gearbox fluid on most Land Rover and Range Rover units. The LT230 takes EP90 (or the Land Rover-specified MTF94 on later units), and the Magna Steyr unit on Discovery 3 and 4 takes a specific ATF spec. Confirm before ordering.
Most gearbox parts returns are caused by ordering errors at the buying stage rather than parts faults. The following are the most common we see across the Land Rover and Range Rover range.
For parts that overlap with the clutch system on manual gearboxes, see the Land Rover clutch parts collection. For driveline parts forward and aft of the gearbox, see the driveshaft and propshaft parts collection.

Land Rover driveline diagnosis guideClutch faults are routinely misdiagnosed as gearbox faults due to overlapping symptoms. This guide explains how to identify the real fault before replacing parts.
Land Rover clutch diagnosis guideThe gearbox controls gear ratios and torque delivery from the engine; the transfer box splits drive between the front and rear axles for 4x4 traction and also provides the low-range gearing on Defender and Discovery models. Both are serviceable assemblies and both fail in distinct ways. Drivetrain symptoms can come from either, which is why most Land Rover gearbox parts returns are caused by mis-diagnosis rather than mis-fit.
ZF 6HP26 transmissions (fitted to Range Rover L322, Range Rover Sport L320, Discovery 3, and Discovery 4) take ZF Lifeguard Fluid 6. ZF 8HP transmissions (fitted to Range Rover L405, L460, Range Rover Sport L494 and L461, and Discovery 5) take ZF Lifeguard Fluid 8. The two fluids are not interchangeable. Confirm the gearbox code stamped on the casing before ordering.
ZF's official position on the 8HP series is fill-for-life. In practice, independent transmission specialists across Europe recommend a precautionary fluid and pan-filter service at around 80,000 to 120,000 km, particularly on vehicles used for towing, frequent urban driving, or high-mileage motorway work. The 6HP26 typically receives a service interval at 90,000 km. Manual gearboxes (R380, MT82, LT77) take a gear oil change at approximately 60,000 km.
The LT230, fitted to the Classic Defender, Discovery 1, Discovery 2, Range Rover Classic, and Range Rover P38, fails in three main ways: output shaft seal leaks (often caused by flange wear behind the seal), input gear bearing wear, and selector linkage faults that mimic gearbox symptoms. Most LT230 issues are repairable with component-level parts rather than a full transfer case replacement.
The R380 five-speed manual was fitted to the Discovery 1 (post-200Tdi), Discovery 2, and Classic Defender from the 300Tdi era through to early Td5 production. The LT77 preceded the R380 on the Discovery 1 200Tdi. The MT82 six-speed replaced the R380 on the Defender 2.4 and 2.2 TDCi Puma. Rebuild kits and individual components for all three are stocked in this collection.
Yes. Most Land Rover transmission service jobs touch both units, particularly fluid changes, seal replacements, and bearing kits. Ordering both at the same time reduces vehicle downtime and is the most common workshop order pattern.
