Why stop there, just get a fresh new complete engine, emission, and fuel system. You already replaced just about all the other components in that truck. I've come to the conclusion many of these gen1 owners are strange birds that lack critical thinking, or maybe just too young to know any better. They rather constantly complain about their issues, than put an end to them.
Bottom line, time for a new truck. I think my brother is going to jump ship, he doesn't like where toyota is going. He's gotten pretty serious about owning a ford maverick, saying its time his hybrid rave4 finds a new owner.

Toyota tech friend of mine recommends all new o2 sensors every 100k if your one of those mpg freaks that likes clean air.
As far as transmissions being rebuilt....as long as they used the same ratio gears, fuel economy should be the same. Doesn't take much intelligence to rebuild a manual stock transmission. I rebuilt my 4 speed munice to crash shift in my drag car a few times after I blew up 3rd gear.
