Why Shouldn't You Use Multi-vehicle Atf In Your Automatic Transmission?

Not each automatic transmission fluid (ATF) is created equal. Different transmissions successful different vehicles person different requirements. Each shaper develops nan transmissions of its vehicles to execute successful circumstantial ways, which intends they request transmission fluid that tin present connected those circumstantial goals — whether they're for efficiency, smoothness, aliases performance. And fluids person very circumstantial guidelines oils and additives selected to meet those requirements. 

Unfortunately, galore car repair shops often usage what's called "multi-vehicle ATF," which is expected to beryllium a one-size-fits-all-style of fluid. This is supposedly meant to thief them work a wide number of vehicles astatine once. However, erstwhile it comes to transmissions, location really isn't a one-size-fits-all fluid, and multi-vehicle ATFs deficiency nan circumstantial qualities your transmission needs to enactment arsenic patient arsenic possible. That's not to opportunity that multi-vehicle ATF is inherently bad aliases will surely and instantly break your car, but it tin origin summation deterioration and tear successful nan agelong tally moreover if you change it astatine regular work intervals.

Originally, multi-vehicle ATF was developed truthful that shops didn't person to transportation respective different kinds of transmission fluids to work nan galore different vehicles that came in. There are respective different transmission fluid specifications recommended by American automakers, but nan 3 biggest existent ones are Dexron VI, Mercon LV, and ATF+4. GM uses Dexron while Ford uses Mercon, and Stellantis/Chrysler uses ATF+. Other automakers from Europe and Japan create their transmissions for different fluid specs, too, truthful multi-vehicle ATF was designed to activity pinch a wide assortment of them. 

Some multi-vehicle ATFs are said to activity for transmissions rated for some nan latest Dexron VI and Mercon LV. For example, Valvoline has an ATF that claims to beryllium "officially licensed for Dexron VI and recommended for Mercon LV" transmissions. It besides intelligibly states that it's recommended for astir GM and Ford vehicles. Other ATFs, however, are broader successful scope, claiming to activity pinch immoderate and each transmissions fluid specifications. Mobil 1 Multi-Vehicle ATF, for instance, has an exertion database arsenic agelong arsenic a Cheesecake Factory menu, and includes every Dexron, Mercon, and ATF+ rating, arsenic good arsenic countless others for different brands. 

Many ATFs, for illustration nan Mobil 1, besides declare to beryllium backwards compatible. In different words, they're said to activity pinch older vehicles that urge ATF specifications nary longer successful production. That tin beryllium charismatic to owners of older cars who can't find transmission fluid that meets their older specs. However, to meet each of those wide varying specifications, multi-vehicle ATFs person to discuss successful definite areas.

Admittedly, location was a clip erstwhile little than a fistful of transmission fluids could activity successful each vehicles. However, arsenic automatic transmissions became much tin and much complex, much circumstantial properties were required. Viscosity isn't nan only facet of ATF, moreover if it's nan astir discussed part. Automakers request definite additives for power management, clash durability, displacement quality, oxidation, and moreover worldly compatibility. ATF interacts pinch astir of nan 1,000+ components wrong a transmission, galore of which are made of different materials, truthful it includes additives to guarantee that nary of those materials are adversely affected. And since each ATF specification goes astir gathering those requirements differently, location simply can't beryllium a once-size-fits-all — particularly if you person a continuously variable or dual-clutch transmission alternatively of a normal automatic. 

While multi-vehicle ATFs tin do a serviceable occupation for a short time, there's nary guarantee that they will usability correctly. Some transmissions require circumstantial levels of viscosity and power guidance properties, allowing them to displacement smoothly and correctly moreover erstwhile nan fluid gets hot. Without those circumstantial fluid properties, they tin grip roughly, wear retired much quickly complete time, aliases moreover neglect entirely, yet starring to a costly repair. 

Furthermore, location are truthful galore ways to get nan correct automatic transmission fluid that it doesn't really make consciousness to usage thing different than what's recommended by nan manufacturer. Between car parts stores, Amazon, aliases nan cardinal different marketplaces retired there, you tin easy find nan nonstop fluid you need. It isn't ever cheap, but it's amended than risking an moreover much costly problem down nan roadworthy by utilizing a generic ATF that isn't afloat compatible pinch your car.
