So basically user error is why they don't recommend trans coolers? LOL
That is no different than people bashing oiled air filters. Less than 1% of all oiled air filters have caused MAF problems and of that less than 1% were caused my filters straight out of the package. The vast majority of the issues are caused by people overoiling their filters when they clean them, or oiling them out of the package when they come pre-oiled.
