Dexron 6 automatic transmission fluid series#

High service life of the product allows ever longer oil change intervals than DEXRON-IIIH.This product meets the latest DEXRON-VI specification and covers the requirements of DEXRON-II and DEXRON-III because it is completely downward compatible. Synthetic automatic gear oil, based on selected basic oils and additives, for use in modern automatic transmissions, in particular cars of the GM Group (Opel). Such conditions will be defined by the manufacturer.Synthetic Automatic Transmission Fluid - with Multi-Vehicle Technology In many cases fluid change interval requirements will be more frequent if the vehicle is operated under severe conditions. The proper time to change automatic transmission fluid will be defined in individual owner’s manuals. This may be the fluid of choice of older Ford classic cars, racing or hydraulic applications.ĪTF Oil Change – Proper Service Intervals This fluid meets old Ford specification and is not commonly recommended for today’s transmissions.

A CVT fluid should be used in this application to ensure proper performance and protection especially with the CVT push belt regarding wear protection. CVT transmissions have continuously changing speed ratios unlike classic automatic transmissions, also known as “step transmissions,” which have distinct gear shifts. Such transmissions are common to hybrid vehicles but can be found on non-hybrids as well. Continuously Variable Transmissions (CVTs)ĬVTs are growing in usage to improve fuel economy. Multi-vehicle transmission fluids have become popular and these may carry GM, Ford and Chrysler certifications but also be suitable for use in Japanese and European vehicles.ģ). For Chrysler the ATF +4 specification is the latest specification. Specification is important with the latest being MERCON LV. Earlier DEXRON specifications would be acceptable for older GM vehicles.

Dexron 6 automatic transmission fluid 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.
