Experimenting with bypassing the AT 4th gear prohibition when cold - Toyota Yaris Forums

My 98 Corona does this but its way more apparent than the Vios and both these cars are in a tropical climate. On a cool night, 25c ambient temp, it will not shift to 4th for a good 5-6 km. If that car were in cold climate, I bet it'd never change to 4th.

I found some old article about toyota ECT on the net and it says this for protection of the transmission.

Makes sense I guess. How good it is for the engine I don't know!
