I searched and found a lot on cars from Europe and the fact they need an adaptor. I've looked at meters and see there are some the provide info on the transmission. Some provide info on the ABS system (expensive ones). I don't want to buy one that won't tell me the basics for engine and trans. And enable me to reset the codes.Did you search?
I'll bet you a dollar that has been asked before
