Why You Should Think Twice Before Letting A Quick Lube Touch Your Honda's Transmission

Most drivers fig it's easy capable to change your transmission fluid, dropping nan pan, draining nan fluid, and refilling it astatine home. However, Honda's automatic transmission work has ever been different. Several older procreation models from nan precocious 1990s to mid 2000s person glaring transmission issues.

The 1999-2004 Odyssey had soul cogwheel harm and torque-converter failure, starring to a awesome warranty hold aft wide breakdowns. Also, nan 2001-2005 Civic, particularly early models, often burned done clutch packs and overheated their transmission fluid, causing harsh shifts and complete breakdown. Even nan 2003–2004 Accord V6 had a 2nd cogwheel that could overheat and springiness retired anytime contempt regular transmission maintenance.

These failures exposed really delicate Honda's transmission creation was to nan nonstop fluid wrong it. While astir automatic transmissions usage planetary gears and torque converters, Honda relies connected a bid of clutch packs and hydraulic unit controls that are person to a manual setup. This creation useful efficiently pinch fluid that meets Honda's precise clash and heat-resistance standards, which is why using nan incorrect transmission fluid could costs you a caller transmission.

Right from nan start, Honda realized its transmissions needed thing different. The brand's first awesome transmission fluid, ATF-Z1, was petroleum-based pinch a viscosity scale of astir 215.5 and kinematic viscosity adjacent 7.64 centistokes astatine 212 degrees, which made it unchangeable astatine precocious temperatures. ATF-Z1 had typical clash modifiers, anti-foam agents, and detergents to support hydraulic unit dependable and forestall buildup wrong valves and solenoids. 

Honda later replaced Z1 pinch ATF-DW1, a afloat synthetic fluid pinch improved oxidation guidance and low-temperature flow. DW-1 maintained akin clash characteristics, allowing it to activity safely successful older transmissions while reducing displacement daze arsenic they aged. Generic fluids can't replicate this equilibrium because they're formulated to meet aggregate manufacturers' requirements astatine once. Hence, they discuss connected cardinal properties for illustration clash coefficient and viscosity stability. Honda's transmissions dangle connected very constrictive clash and unit tolerances to power clutch engagement and displacement timing, truthful moreover insignificant deviations tin upset really nan strategy builds and releases hydraulic pressure.

Quick-lube shops push difficult for transmission flushes erstwhile you want to switch your car's fluid. Most of these shops hook your car up to a power-flush instrumentality that forces fluid done nan strategy nether precocious pressure. Though these approaches whitethorn activity for definite cars, they spell problem for Honda transmissions that dangle connected precise fluid chemistry and controlled flow. 

Such unit tin overload vulnerable valve bodies and solenoids, causing soul seals to blow. Honda transmissions besides person a mini magnet connected nan drain plug that traps nan good metallic particles people shed by nan gears and clutch components. A high-pressure flush from a quick-lube shop tin sound that buildup loose and nonstop nan particles backmost into circulation, wherever they tin settee successful tight passages and interfere pinch soft fluid flow.

The safer attack is simply a elemental drain-and-fill utilizing genuine Honda ATF astatine nan intervals listed successful nan owner's manual. That's astir how agelong your automatic transmission fluid should past earlier you alteration it, usually astir 30,000 to 60,000 miles depending connected really and wherever you drive. The transmission attraction involves replacing a information of nan fluid without forcing debris done nan strategy aliases stressing nan soul seals. After 2 aliases 3 services, nearly each nan aged fluid is cycled retired naturally. It takes a spot longer, but it keeps nan transmission cleanable and pressurized correctly.
