Automatic transmission and driveline fluid selection
Transmission fluids chosen by equipment requirement—not colour.
Evaluate LubeMax transmission fluid using the exact transmission design, OEM fluid requirement, operating conditions and current product documentation.
Protect shift quality
Automatic transmission fluids are application-specific.
Transmission fluids may influence friction behaviour, hydraulic control, wear protection, cooling, seal compatibility and shift quality. A product name, red colour or similar viscosity cannot establish suitability for every transmission.
| Transmission question | What to identify | Why it matters | Decision source |
|---|---|---|---|
| What transmission is fitted? | Manufacturer, model, year and transmission code | Different units in similar vehicles may require different fluids | Vehicle manual or service data |
| What fluid is required? | Exact OEM designation or stated equivalent performance requirement | Broad terms such as ATF may be insufficient | Service manual and current TDS |
| What is currently in service? | Product name, condition and service history | Unknown or mixed fluid increases changeover risk | Maintenance records and inspection |
| How is the vehicle used? | Load, towing, heat, traffic, terrain and service interval | Severe duty can raise fluid temperature and stress | Operating profile |
| What service is planned? | Drain-and-fill, pan service, filter change or approved exchange procedure | Incorrect procedures can affect level, contamination and operation | Manufacturer’s service instructions |
LubeMax product range
A focused LubeMax transmission-fluid pathway.
Use the product name and grade as the starting point, then confirm the application and equivalent performance requirements in the current LubeMax TDS.
LubeMax ATF III
A LubeMax transmission-fluid product for evaluation only where the current TDS and equipment requirement support its use.

Application planning
Five checks before servicing a transmission.
Transmission-fluid errors can affect shift behaviour, component durability and service outcomes. Confirm the system before selecting or changing a fluid.
- Identify the exact vehicle, transmission model and transmission code.
- Obtain the OEM fluid designation from current service information.
- Confirm the existing fluid and previous service history where possible.
- Review seals, contamination, operating temperature and changeover procedure.
- Set the final fluid level using the manufacturer’s specified method and temperature.
Where selection matters
Match the lubricant to the equipment and duty.
Product choice should reflect the component, operating environment, maintenance practice and consequences of an incorrect recommendation.
Automatic transmissions
Use the exact transmission requirement and approved service procedure for the vehicle.
Mixed-fleet control
Prevent product confusion by documenting vehicle, transmission and required fluid before issue.
Service consistency
Record the fluid used, service procedure, filter work and final level-setting method.
Changeover evaluation
Assess unknown fluid, contamination, compatibility and the correct service procedure before change.
Responsible specifications
Equivalent performance is not formal approval.
LubeMax products do not currently carry API approval, licensing or certification. Any API, OEM or industry reference describes equivalent performance to the stated requirement unless the current product TDS expressly identifies a formal approval.
Technical documents
Use current product information.
Request the exact document for the product and grade being evaluated. Never substitute one product’s data sheet for another product with a similar name.
Technical Data Sheet
Applications, benefits, equivalent performance references and typical characteristics.
Safety Data Sheet
Safe handling, storage, exposure control and emergency information.
Product Selection
Support for equipment requirements, mixed fleets, unusual duty or changeover questions.
Frequently asked questions
Transmission fluid questions.
Can transmission fluid be selected by colour?
No. Colour is not a performance specification and does not prove fluid type, friction characteristics or compatibility.
Can LubeMax ATF III be used in every automatic transmission?
No. Use it only when the equipment requirement and current LubeMax TDS support the application.
Is ATF III an API approval?
No. LubeMax products do not currently carry API approval, licensing or certification. Product suitability depends on the stated equivalent performance references and equipment requirement.
Can different transmission fluids be mixed?
Do not assume compatibility. Identify both products and follow the transmission manufacturer’s service and changeover guidance.
Should a transmission be flushed?
Use only a service procedure permitted for the specific transmission. The correct approach depends on design, fluid condition, contamination and maintenance history.
What information is needed for a recommendation?
Provide vehicle and transmission details, OEM fluid requirement, current fluid, service history, duty cycle and reason for service.
Where can I request the TDS and SDS?
Use the LubeMax Technical Resources centre and specify LubeMax ATF III.
Does LubeMax ATF III have SON approval?
All LubeMax products have SON approvals except where the current TDS clearly states “Pending approval.”
Technical and commercial support
Need to confirm a transmission-fluid requirement?
Send the vehicle, transmission code, OEM fluid designation, current product, service history and operating conditions before selecting an equivalent.
