Regarding the transmission
Regarding the transmission problems with the 3rd generation Toyota Tacoma -- I've got a 2017 double cab long bed, and the 6-speed auto trans is really poorly programmed. The truck is a headache to drive in hilly terrain, and even against a headwind. It continuously hunts around for gears, and is normally in the wrong gear. At highway speeds it is always in too low a gear, with scary high engine rpm's, while below 35 mph it is exactly the opposite, hanging in a high gear and forcing rpm's down to a ridiculous (and damaging) 800 rpm! Other problems include sloppy, lurching shifts and complete absence of 5th gear. The dealer says there is no way to fix or adjust the trans, and won't even check the fluid level, which is sealed and very hard to get at. This is not a good vehicle to buy used, as the engine is often forced to run at over 5,000 rpm for many miles, and therefore will wear out early.
