How Often Should the Transmission Fluid of Mitsubishi Outlander Be Changed?
2 Answers
Outlander's transmission fluid should be changed every 40,000 kilometers or every two years, whichever comes first. Below are the impacts of not changing the transmission fluid and an introduction to its functions: Impacts of not changing the transmission fluid: If the transmission fluid is not changed, it will lead to increased wear of internal moving parts, eventually causing abnormal noises inside the transmission and difficulties in shifting gears. Transmission fluid is an oil product that keeps the shifting system clean. Functions of automotive transmission fluid: Reduces friction and wear, controls the friction of the clutch and the performance of the synchronizer, carries loads (low-speed high torque, vibration loads), dissipates heat, reduces vibration and noise, removes contaminants from gear meshing—cleaning function, prevents corrosion, prevents pitting and surface metal tearing, isolates metal surfaces, and prevents direct contact between metal bodies.
I've driven my Outlander for over three years, and transmission fluid maintenance is something you really need to take seriously. According to the manual, older models require a change at 50,000 km, but the manual for newer CVT models specifies inspection at 40,000 km and mandatory replacement at 60,000 km. For drivers like me who frequently encounter city traffic congestion, it's safer to change it at 50,000 km. Last time at the dealership, the technician said you can also judge by the fluid color – if it turns dark and thick, it needs immediate replacement. Don't cheap out and use the wrong specification – you must use Mitsubishi CVT J4 genuine fluid or equivalent certified products, otherwise you risk damaging the transmission. If you delay replacement beyond 70,000 km, my neighbor's vehicle developed gear shift jerks – the repair cost nearly half the car's value.
