Having a bit of a hard time getting a clear answer on this one... Dealer says "When it needs it", owners manual maintenance schedule makes no mention and the internet says "Did it cause I wanted to"....
I have 220,000 km on the car with original ATF still in her, 98% of the mileage is highway kilometers.
There's no obvious shift slippage but I'm just starting to get weirded out with still having the original fluid in.... Thoughts?
