DEXRON-VI can be used in any proportion in past model vehicles equipped with an automatic transmission, in place of DEXRON-III (for instance, topping off the fluid in the event of a repair or fluid change). DEXRON-VI is also compatible with any former version of DEXRON for use in automatic transmissions. TIP: Simply topping off the fluid is adequate, but a full drain and replacement is preferred, to obtain the full benefit.

Because it has a high viscosity index, PEAK® DEXRON® III/MERCON® ATF can be used over a wide temperature range – providing excellent low-temperature fluidity while retaining desired viscosity at high temperatures. Specific benefits and product attributes include: Smooth shifting performance where DEXRON® III or a MERCON® fluid is specified

IMPORTANT: As with previous upgrades, DEXRON-VI fluids are designed to be backward compatible with earlier transmission hardware. But more important, earlier type fluids are NOT FORWARD COMPATIBLE with transmissions that were designed to use DEXRON-VI.

This automatic transmission fluid type ceased production in 2007. Mercon is used in Ford vehicles and is not compatible with Ford and Toyota's type F fluid. After 2007, vehicles using Mercon can be filled with Mercon V. Mercon V was introduced in 1997 for use in the Ranger, Explorer, Aerostar and other Ford vehicles.

Driving conditions generate heat in the transmission. Automatic transmission fluid cools the transmission components and allows for smooth transfer of power to the transmission for proper function. Different car makes and models require various types of automatic transmission fluid. Two common types are Dexron and Mercon. Mercon Mercon entered the market in 1987, according to the book The Role of the Chemist in Automotive Design by Herman K. Phlegm.
