Automatic Transmission Fluid (ATF) Guide: Dexron, Mercon and Multi-Vehicle Fluids

Automatic transmissions are built to work with specific fluids. Using the wrong one can cause slipping, harsh shifts and, over time, costly repairs. With so many specifications on the shelf, here is how to keep it simple.

Always start with the owner's manual

The vehicle maker specifies the fluid. The spec is usually printed in the owner's manual and sometimes on the transmission dipstick. Match that spec exactly.

The main ATF families

• Dexron (GM) — Dexron VI is the current common GM spec and is generally approved for use where older Dexron fluids were specified. Check the manual for newer GM transmissions that need a different fluid.
• Mercon (Ford) — Mercon LV is used in many newer Ford automatics. Older Fords may call for Mercon V. They are not the same, so check the spec.
• OEM-specific fluids — Many Toyota, Honda and other import vehicles call for the maker's own fluid, such as Toyota WS or Honda ATF.
• Multi-vehicle ATF — Designed to meet many specs in one bottle. Read the label to confirm it lists the vehicle's spec.

CVT and dual-clutch are different

Continuously variable transmissions (CVT) and dual-clutch transmissions use their own special fluids. Never put regular ATF in a CVT unless the label specifically says it is approved.

Tips for shops and parts counters

• Stock the top specs for the vehicles in your area: Dexron VI, Mercon LV and a quality multi-vehicle ATF.
• Keep popular OEM fluids such as Toyota and Honda on hand for import customers.
• Buy by the case or in bulk to lower your cost per quart.
