AUTOMATIC TRANSMISSION OIL CHANGE SERIES

Specification is important with the latest being MERCON LV. Earlier DEXRON specifications would be acceptable for older GM vehicles.

AUTOMATIC TRANSMISSION OIL CHANGE SERIES

For GM it is the DEXRON series of specifications with the mainstream specification being DEXRON VI for newer GM vehicles. Rather it is defined by specification, certification or application.įord, GM, and Chrysler have established their own specifications for automatic transmission fluids. Ford, GM and Chrysler ATF specifications:ĪTF Fluids are not defined by a weight as is motor oil. The types of Automatic Transmission Fluids fall into a few categories:ġ). Always follow the recommendation of the vehicle manufacturer to ensure the proper fluid is used and fluid change interval is maintained. This recommendation can commonly be found in your vehicle owner’s manual. Low temperature flow ensures effective operation of hydraulics and electronics controls at low temperatureĭepending upon your vehicle manufacturer, model type, and model year, a specific automatic transmission fluid will be required to ensure proper transmission performance and protection.Viscosity stability helps maintain viscosity or proper fluid thickness over a wide temperature range.Extreme pressure/load carrying performance ensures anti-wear and gear durability.Frictional Characteristics enables smooth gear changes by supplying the correct friction to the transmission clutches and bands.Heat resistance and thermal stability, helps prevent deposit and sludge from forming as the result of the high temperature operation of the transmission.

Critical areas of performance include the following: Automatic transmission fluid is a critical component of any automatic transmission. Also referred to as ATF, this fluid ensures proper operation, performance and protection of the automatic transmission. The vast majority of passenger car and light truck transmissions operate automatically, that is without the need to manually shift gears.
