I agree about online reviews, but there have been more issues with 4th gens than I expected, even on an all new truck. So I can see why Toyota quality is being questioned more now than ever before.Negative reviews and trashing on things in general do much better on Youtube than anything positive. Not saying that there isnt merit to the vid, just something to keep in mind.
The truck was not on its 3rd transmission, that's just generating clickbait. His first truck had trans issues (clunk from 1st to 2nd, metal found in trans fluid) and it was replaced under warranty. He wasn't happy with it after the repair (rattle that couldn't be found/fixed, got hot in 4 Hi at low speeds going uphill) and his dealer made him a deal to swap...
