ATF (Automatic Transmission Fluid)
ATF, or Automatic Transmission Fluid, is the specialised hydraulic fluid that lubricates, cools, and operates the clutch packs and torque converter inside an automatic transmission.
What it means
ATF does several jobs at once. It lubricates gears and bearings, transfers heat away from the gearbox, provides the hydraulic pressure that engages clutch packs, and on torque-converter automatics, transmits engine torque to the wheels. Different transmissions need different ATF specifications: a ZF 8HP gearbox in a BMW or Audi needs one specific fluid, a Mercedes 7G-Tronic needs another, a DSG dual-clutch needs a different fluid again, a CVT needs CVT-specific fluid (not ATF), and so on. Using the wrong fluid causes shift quality issues at best and gearbox damage at worst. Manufacturers vary in their service recommendations: some specify a fluid change at 60,000 to 80,000 km, others claim lifetime fill, which often means lifetime of the warranty rather than lifetime of the car. In tropical, stop-and-go traffic, lifetime fill is rarely the right call.
Why it matters in Singapore
Singapore traffic puts automatic transmissions in their hottest operating zone for hours every day. Heat is the primary enemy of ATF additives. A more conservative service interval (every 60,000 to 80,000 km even on lifetime-fill transmissions) is one of the cheaper ways to avoid an expensive transmission rebuild later.
How Revol Carz handles this
Revol Carz Garage services ATF using the correct OEM-spec fluid for each gearbox code (not just each model). We drain through the gearbox properly rather than relying on a top-up alone, replace the filter where applicable, and perform any required adaptation via brand-specific tools.
