Hmm, why can this AT(or even diff fluid) service not be done like a regular oil/coolant change, with easily accessible filter cartridge/unit, and fixed fill volume, e.g. 7 liters?!?
E.g. there can be a drain hole at bottom of pan, and then a fill hole that is higher than the fill level in the oil pan. And a little transmission fluid pump through a filter? Why is it not designed that way? There seems to be room for innovation!
