Ford f-150, chevy silverado, toyota tundra. Which has best transmission? Used to get 120/140K miles out of the fords, 75 to 90K miles on the silverado, Like my present Tundra but haven't towed much with it like I did with the others. 40 years of towing 18/21ft. bass boats over the 40 years. Generally club tourneys twice a month, one prefish and 1 tourney per month. Your experience, how do the tranny's hold up now??
