Hi, I've just had my gearbox 'megaflushed' and oil change (130,000 Miles), and was told that the oil was very dirty.
When I said I was following the recommended time (10 years or 150,000 miles), I was told to forget recommended time, all automatic gearboxes should have an oil change at 60,000 miles, as he said, "you wouldn't leave your engine oil in that long".
Is this generally known, or am I playing catch-up as usual ?
