Yeah it would have to be the normal Auto box. The issue with leaving the oil for a long time and changing is some of the fluid fins in the gearbox, the gunk gets unsettled and blocks the veins which then can leave a gearbox useless. This usually happens on high mileage automatic gearboxes that has never had an oil change and then suddenly has an oil change.
People then blame the new oil or the gearbox manufacturer when it's neithers fault.
On auto boxes, you either change the fluid regularly, or not at all.
DCT doesn't have this issue.
