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.
