What to Compare Before Buying
- Fluid requirement: This is an automatic transmission fluid, so check that your vehicle calls for ATF rather than another transmission or hydraulic fluid.
- Approval match: Compare the listed approvals and required specifications for the exact vehicle or transmission.
- Pack size: The bottle contains 1 L, so consider whether you need a single top-up or multiple litres for a service.
- Transmission type: It is described for automatic transmissions, including a wide range of Japanese cars, light commercial vehicles and SUVs, plus most European passenger cars with 4 or 5 speed automatic transmissions.
What Else You May Need
Check the vehicle handbook or service information for the exact fluid specification before use. If the vehicle requires a different ATF standard, a different product should be chosen.
Before You Decide
Confirm the exact transmission fluid specification, the required approval or standard, and whether 1 L is enough for the job. If your vehicle calls for Dexron III, Mercon or one of the listed approvals, this bottle matches that type of requirement.
