It's an emission thing for the computer. Why fight it, all yaris automatics do it. I find that it takes me about 2 miles and reaching a temp of 137 degrees and it slips right into 4th. I'm still getting 38.5 to 41.5 mpg on her and drive the interstate to work for 28 miles at speeds around 75. Not bad.

I would live with it and not push the car as it's designed that way.

But you are burning MORE gas when doing that. I dont drive on the highway were I can get 40 mpg. I just drive 6.5 miles to work and back everyday. A mile or two of that is being stuck in 3rd gear.This winter with winter crap gas and temps in the teens and 20s in the morning, I got lows of 28 mpg. And I never exceeded 45 mph. With a manual you can be in 5th gear ANYTIME you want. So dont try to tell me it HAS TO be that way because it doesnt.

" A mile or two of that is being stuck in 3rd gear. "

Same here , usually 1 and 1/2 miles in 3rd when cold . Then a few seconds after the operating temp light goes out the 4th gear ( overdrive ) kicks in .

According to toyota designers yes it does. you should have bought a manual if you want to be in high gear in a hurry. Live with it or trade it for a manual.

Better yet take public transportation and you save a load of gas and we save a load of gas.

Eat the cake and have toyota laugh at you if you try to get work done under warranty, providing the car is still under warranty, because you mod it. m
