Think about what you do when running an engine in ?
You are told NOT to load it up and make it lug !!
A few more rev's means lighter load , what would be easier on you , lifting one big heavy 100 Kg box from here to there or lifting 4 x 25 Kg box's from here to there ?
Same principle applies to your engine , more rev's = lighter load = less wear to a certain point .
All engines have a optimum working range and although I don't know exactly what the 1uzfe range is , I can say that it's not down at 1500 odd RPM !!
As to the gearbox if you call a submarine an airplane , no matter how many times you say it , IT STILL CAN'T FLY , calling the gearbox a four speed doesn't alter the fact that it really is just a 3 speed with a torque convertor lockout , what would you call it ?
Calling it a four speed sounds better and is more conveniant , the later model [ late 98 ] is actually a four speed with a convertor lockout , again called a 5 speed for the same reasons .
Even at high revs a torque convertor has slippage , locking it so it is a direct drive has the effect of an extra gear .
Go and talk to an engineer about loads on engines .

It's not about winning or losing , just a matter of getting it right , maybe I've got it wrong , I was always under the impression that the gearbox was a true 3 speeder with O/D being the " Fourth Gear " ?
I've been running around the last two days seeing how many changes the box makes with the O/D off [ light on ] then hitting the switch , so far I can only count/feel 3 changes from standstill to 80 K [ 50 MPH ] and then the extra change when I click the O/D button .
What I don't know is from standstill does the car actually start in 1st ?
Or is it actually a four speed [ with four sets of clusters ] and O/D torque convertor lock-up actually being like a fifth gear ?
But you can't have it both ways , either it's a 3 speed with the T/Q lock-up counting as the fourth gear or it's a four speed with the O/D in effect being like a fifth gear .
