Range Rover L322 ZF 6HP gearbox service — Milton Keynes
From 2006 the third-generation Range Rover (L322) has the ZF six-speed automatic, in the 6HP26 X version built for a separate transfer box. We renew the pan and filter, exchange the fluid, check the connector sleeve and reset the adaptations — priced to your engine.
From £390, priced to your car. Get a price first — send the registration and we confirm the gearbox.
Which Range Rover L322 cars have the ZF 6HP
Gearbox versions are as published by the car maker, ZF and the sources below. We confirm your car's exact gearbox from its VIN before ordering parts.
What to know about the 6HP in a Range Rover L322
- The “X” in 6HP26 X means the gearbox is built for four-wheel drive through a separate transfer box — the L322 layout. Pan, filter and fluid are ordered by your VIN.[2, 3]
- Earlier L322s (2002–2005) have a five-speed automatic instead: a ZF 5HP behind the V8, and a GM 5L40-E behind the Td6 diesel. We service those too, but they are not 6HPs.[1]
- The 4.4 TDV8 L322 (2010–2012) came with the eight-speed ZF 8HP70 instead of the six-speed — we confirm which one your car has from its registration.[1]
- ZF calls its automatics maintenance-free in normal use, but recommends an oil and filter change after 50,000 to 75,000 miles because the oil wears — and it ages faster with towing, high speeds or hard driving. Most of these cars are older than that on their first fill.[3, 4]
What the service includes
- Road test with live data before we start and again before handover
- New sump pan and filter (together where the filter is built into the pan), ordered by your car's VIN
- The fluid specified for your gearbox, by part number
- Check of the connector sleeve where the wiring enters the gearbox — the common 6HP leak — quoted before any repair
- Dynamic fluid exchange — torque converter and cooler, not just the pan
- Level set at the temperature the gearbox calls for, adaptations reset, leak check, and the work recorded against your car
Each step is explained on our ZF 6HP gearbox service page.
ZF 6HP or ZF 8HP? The eight-speed ZF 8HP replaced it in later cars — for the Land Rover models with the 8HP, see Range Rover Sport, Range Rover, Land Rover Discovery and Land Rover Defender. We confirm which one your car has from its VIN.

Questions we get asked
Which gearbox does my Range Rover L322 have?
2006-on L322s have the ZF six-speed 6HP, except the 4.4 TDV8 (2010–2012), which has the eight-speed 8HP70. 2002–2005 cars have a five-speed (ZF behind the V8, GM behind the Td6). Send us your registration and we confirm it before quoting.
My L322 shows “Gearbox fault” or the PRND letters are flashing. Is that the fluid?
Not usually. On the L322 that is most often the gear position sensor, which we diagnose and fix — see our page on the Range Rover L322 PRND and gearbox fault. A fluid service will not cure a sensor fault, so we read the fault codes first.
Is the L322's gearbox oil filled for life?
The car was sold that way, but ZF recommends an oil and filter change after 50,000 to 75,000 miles. Most L322s are well past that on the original fluid. With an unknown history, we recommend doing it now.
How much is a ZF 6HP gearbox service on a Range Rover L322?
From £390, priced to your car. The price moves with which 6HP version it has, the pan and filter part and how much has to come off to reach it. Give us your registration and we confirm a fixed price in writing before we start.
