How to replace auto tranny fluid - Toyota Yaris Forums

Here's my 2 cents:

After filling up the transmission fluid, I went to measure if I had put enough. The mechanic's manual tells us to measure the fluid level while the engine is running at a normal operating temperature (see image below), set on Park, and while the car is level. The latter is very important and will have a significant effect on your fluid level readings. Here's the experiment I did:

Parked on the left side of the street, the car was rolling a few degrees left. The ATF level would read below the normal quantity.

Parked on the right side of the street, the car was rolling a few degrees right. The ATF level would read above the normal quantity.

I wouldn't believe such a small inclination change would have that much of an effect on the ATF level, so I repeated my experiment to convince myself it was real. The neighbors must have tought I was crazy...
