My brother recently got a 2002 Toyota Tundra 4.7 with 200K miles in December. It needed (and still does) some work done but nothing major that affected drivability. Today he informed me that his transmission cooler blew a line and quickly puked transmission fluid into the radiator which went all though the cooling system. He said that he stopped driving it shortly after but did experience slipping when driving away from a stop sign, I'm assuming it puked too much ATF causing low pressure. It was towed to the shop and hopefully will know more on Monday. They told him the transmission and cooling system would need to be flushed and I'm not sure what else. I feel bad for him since he just got the truck not even a couple months ago. He still has his first truck, a 1991 Ford Ranger with 380K miles on it that he can drive for the time being but it just stinks that he will have to sink this money into the Toyota. Hopefully it wont cost too much as he plans on replacing the timing belt (unknown last replacement).
