Description

Castrol ATF Dex III is a synthetic based product which was originally designed for use in pre 2005 automatic transmissions fitted to General Motors vehicles.  Due to it having a high viscosity index it is specified for many industrial and offshore applications where Dexron II or III or Mercon performance is required.  It should not be used where Dexron® VI, Mercon® V or Mercon® SP are required.

Approval Status

Meets Dexron III-IH, IID and II. Suitable as Power steering fluid.

Features and Benefits

Enhanced friction durability prolongs transmission life and promotes smooth shifting.
