Toyota Innova Gearbox Oil Guide — 6AT & 5MT
Innova 6AT uses Toyota ATF WS (8.5L full drain). 5MT uses 75W-90 GL-4 manual gearbox oil. Change AT fluid every 40,000–60,000 km to prevent judder.
Innova 6AT vs 5MT Gearbox Fluid
AN140 Innova 6-speed automatic: Toyota ATF WS (Automatic Transmission Fluid World Standard), capacity 8.5L full drain / 4L partial. Change every 40,000–60,000 km. 5-speed manual (petrol variants): Toyota 75W-90 GL-4 manual transmission oil, change every 80,000 km. AT fluid is the most commonly skipped maintenance item on used Innovas — a degraded ATF causes harsh gear changes and eventual solenoid failure.
Toyota Gearbox Fluid — Malaysia Guide
Toyota petrol automatics use ATF WS (World Standard) — do NOT substitute with Dexron III or generic ATF, which can cause harsh shifts and seal damage. CVT models use Toyota Genuine CVT Fluid TC — never use generic CVT fluid. For Hilux/Fortuner 6AT diesel: use Toyota ATF WS, change every 40,000–60,000 km. The CVT fluid for Vios/Yaris is often listed as 'lifetime' — change it every 40,000–60,000 km in Malaysian conditions to prevent CVT judder.
