5 Speed Auto
I pay alot of attention to transmissions.
The only concerning thing I have seen discussed here, and experienced myself, is a minor lag coming out of Park into gear. I experience this only when it's cold, and I do not engage for at least 30 seconds after starting the engine.
Historically, this 'lack of rapid pressurization' is an early warning sign for autos, likely indicating a dirty filter, or worse.
Bear in mind, I'm new to Toyota, and I do not invent problems, but have experienced this lag myself. Just a characteristic.
While we're talking trans, I also feel like if you got 5 of 'em, why cruise around town in 5th, the gear capable of going 100+?
I usually keep it out of O/D until 40. There is no ? the taller the gear, the weaker the gear, and, it mite help gas mileage. Mine consistently reads out 18.2 - 18.8; a lie I kno, but a pretty good [numerical] lie compared to most of the 4.7s I see posting #s.
