The factory maintenance schedule for my 2008 Mazda MX-5 with the 6-speed manual gearbox calls for a gearbox and differential fluid change at 60k miles or 48 months, whichever comes first.
I get the 60k mile requirement, but not sure about the 48 month limit, considering both fluids operate in essentially closed environments. Plus, I’m not aware of any other OEM that bases transmission fluid changes on anything other than mileage.
What’s the consensus here: same logic as bottled motor oil having a shelf life? A way to make sure fluid hasn’t escaped somehow?
Given the MX-5’s ground clearance, even with Rhino Ramps and jacks stands this is not a DIY project to love.
Thanks.
