307 movement indicator

Hi friends, I'm using the 2003 stw automatic 307. The overheat of the car passes 90 braz while driving the car. On the long slopes, the traction decreases a little, the temperature of the hand rests in red, it comes back to the 95s when it gets flat. the fan is running but i don't understand this is normal. thanks.

not normal,
There are several reasons, I think show the car.
Also, it is not good to use high temperature for automatic transmission.

The master said that he worked for a long time and checked it. He said that it is normal. When the car is forced, the pointer is red on the slopes.

Is your engine oil change time close? (In these important strains, the motor temperature will increase due to friction.)

It can exceed 90, but it is not normal for it to endure red. 120-130 damages very high engine

I'll take it back to a mechanic, now. The maintenance is regular, but, let's not damage the engine, unless we've had it until this hour.
