Toyota Yaris CVT Fluid Guide
Yaris petrol CVT uses Toyota Genuine CVT Fluid TC. Hybrid uses e-CVT Transaxle Fluid FV. Change every 60,000 km. Low-speed shudder is the main symptom of degraded fluid.

Yaris CVT Fluid — Toyota CVT Fluid TC
Yaris petrol uses a steel-belt CVT (K120 unit from Aisin). Fluid: Toyota CVT Fluid TC — a dedicated formula that cannot be substituted with generic ATF. Capacity: ~5L for drain-and-fill. Change every 40,000–60,000 km. Using wrong fluid causes belt slippage, shudder, and rapid CVT wear. The Yaris Hybrid uses e-CVT (planetary gear-based motor-generator system with Transaxle Fluid FV) — this is a separate service.
Toyota CVT Fluid — Malaysian Advice
Toyota's Super CVT-i uses Toyota Genuine CVT Fluid TC — not Dexron, not Toyota ATF WS, and not any generic CVT fluid. Using the wrong fluid causes the characteristic CVT judder (shudder at 40–80 km/h under light throttle). Toyota markets the fluid as 'lifetime fill' but Malaysian heat and city stop-start traffic degrade it by 60,000 km. A fluid change (RM 180–280) resolves most CVT judder cases. If judder persists after fresh fluid, the CVT may need internal inspection.
