ATF & Steering Fluid
ATF and steering fluid for Land Rover automatic gearboxes, power steering and ACE hydraulic systems, including fluids for ZF 4HP, 6HP and 8HP transmissions, Freelander 1 JF506E, Freelander 2 and Evoque 6-speed automatics, Dexron III systems and Discovery 2 ACE.
Start with the gearbox or hydraulic system being serviced, then match the exact fluid specification on the product page. ZF 4HP, 6HP and 8HP gearboxes, JF506E, later 6-speed automatics, power steering and ACE systems use different fluids and should not be selected by vehicle name or fluid colour alone.

Find the right ATF or steering fluid
Automatic transmission and hydraulic fluids are selected by gearbox family and fluid specification rather than the vehicle name alone. Identify the gearbox or system first, then match the required Ravenol, ZF or Land Rover fluid reference shown on the individual product page.
| Job | Best place to start | Check before ordering |
|---|---|---|
| Discovery 2 ZF 4HP22 automatic gearbox service | Ravenol ATF 5/4HP | Confirm the ZF 4HP22 gearbox and calculate the quantity required for the intended service |
| Freelander 1 JF506E automatic gearbox service | Freelander 1 JF506E fluid (STC50531) | Confirm the JF506E automatic transmission and the quantity required for the service being carried out |
| Freelander 2 or Evoque 6-speed automatic gearbox service | Ravenol T-IV ATF | Confirm the gearbox and required fluid specification before filling or topping up |
| ZF 6HP automatic gearbox service | ZF Lifeguard Fluid 6 | Confirm the gearbox family, required fluid reference and service-fill quantity |
| ZF 8HP automatic gearbox service | ZF Lifeguard Fluid 8 | Confirm the vehicle uses a ZF 8HP gearbox and check the required Land Rover or ZF reference |
| Transmission or steering system requiring Dexron III | Ravenol ATF Dexron III H | Confirm that Dexron III is the specified fluid for the particular transmission or steering system |
| Power steering service or top-up | Match the fluid to the vehicle and steering-system specification | Do not assume every Land Rover power steering system uses the same ATF or central hydraulic fluid |
| Discovery 2 ACE servicing | Discovery 2 ACE fluid | Confirm that Active Cornering Enhancement is fitted and use the specified central hydraulic fluid |
Check the fluid specification before ordering
ATF is not a single universal fluid. Land Rover automatic gearboxes span several different transmission families, while power steering and ACE systems introduce further hydraulic-fluid specifications. Similar-looking fluids can have completely different friction, viscosity and compatibility requirements.
System being serviced
Identify whether the fluid is for an automatic gearbox, power steering system or Discovery 2 ACE system.
Identify whether the fluid is for an automatic gearbox, power steering system or Discovery 2 ACE system.
Gearbox family
Confirm the actual automatic transmission, including ZF 4HP, ZF 6HP, ZF 8HP or JF506E where applicable.
Confirm the actual automatic transmission, including ZF 4HP, ZF 6HP, ZF 8HP or JF506E where applicable.
Fluid specification
Match the complete fluid specification or Land Rover/ZF reference rather than relying on the words ATF or power steering fluid alone.
Match the complete fluid specification or Land Rover/ZF reference rather than relying on the words ATF or power steering fluid alone.
Service quantity
Allow for the difference between a small top-up, a normal drain and refill, and a gearbox service involving the sump, filter or a greater volume of fluid.

Understanding the different fluid types
The fluid name and specification should be used together. The products in this section cover several generations and designs of automatic transmission as well as power steering and ACE hydraulic systems; they are not interchangeable simply because they are all sold as transmission or hydraulic fluids.
| Fluid | Main use within this section | Important distinction |
|---|---|---|
| Ravenol ATF 5/4HP | ZF 4HP and 5HP automatic gearboxes where the stated specification matches | Separate from the later ZF Lifeguard 6 and Lifeguard 8 fluids |
| JF506E fluid (STC50531) | Freelander 1 JF506E automatic transmission | Use the specified JF506E fluid rather than selecting a general ATF by vehicle age alone |
| Ravenol T-IV ATF | Freelander 2 and Evoque 6-speed automatic transmissions covered by the product specification | Match the gearbox and required specification before use |
| ZF Lifeguard Fluid 6 | ZF 6HP automatic gearboxes using the corresponding Lifeguard 6 specification | Match the gearbox and fluid reference rather than selecting by vehicle model alone |
| ZF Lifeguard Fluid 8 | ZF 8HP automatic gearboxes using the corresponding Lifeguard 8 specification | Lifeguard 8 and Lifeguard 6 are separate fluids for different gearbox families |
| Ravenol ATF Dexron III H | Automatic transmissions and power steering systems specifically requiring a Dexron III fluid | Confirm the required specification before using it for either transmission or steering work |
| Ravenol SSF | Discovery 2 ACE and selected power steering systems requiring central hydraulic fluid | Central hydraulic fluid rather than a general replacement for automatic transmission fluid |
