just take her car and the gps, and see for yourself. you'll know in a matter of seconds, if it's accurate. if it knows you're going 23 mph it should know your going 70. if the convertor is slipping, your rpms will be excessive. are you positive it's shifting into third? run through the gears manually, and see what is what.
