The circumstances that Hyundai foresees warranting transmission fluid replacement are these: Vehicles with a manual transmission – a gearbox – should have the oil lubricating the gearbox's internals replaced every 120,000km. However, Hyundai also recommends that in the event that the Santa Fe is frequently and regularly subjected to tough driving conditions, the ATF should be replaced every 100,000km. The owner's manual for our long-term Hyundai Santa Fe indicates the ATF need not even be checked or serviced for the effective service life of the vehicle (eight years). Neglect the ATF and the transmission will wear prematurely. In constant contact with moving parts its viscosity – its 'body' to hijack a term coined by vignerons – gradually breaks down.įurthermore, it often becomes inundated with tiny metal filings resulting from long-term abrasion where parts make contact with each other. Not only does ATF lubricate the moving parts within the transmission, including the planetary gears, it also serves as the hydraulic medium for the torque converter, essentially a viscous coupling that serves as the clutch in a traditional (epicyclic) automatic transmission.Ĭompanies producing ATF stir in other compounds that inhibit corrosion, clean metal surfaces, enhance viscosity (further reducing internal parts wear) and prolong the life of the fluid itself.īut as advanced as ATF is, sooner or later it will need to be flushed out of the transmission and replaced with a fresh batch. Automatic transmission fluid (ATF) is different again, usually being a mineral oil, or else it can be synthetic – and it is a very sophisticated product indeed.
