Transmission clunky when getting in 3rd gear

What is your "regular" manual transmission oil?

Non-synthetic 75w90. Toyota says GL5 or GL4 is fine, but GL4 is probably the better bet (less slippery). I don't remember what brand I used but likely Quaker State. Interestingly I called a Toyota dealer to buy some OE fluid and they said they just use bulk 80w90...... .

Let's be very clear: The Yaris gearbox is always going to be a little clunky/noisy. It's just not a very smooth box. It is, however, a very durable unit and works fine for the application with the correct oil. This is one of those cases where you should listen to the engineers. The only reason to consider different M/T oil is really if you are regularly operating outside of the temperature range they designed the car for. And yes, some of you are probably at the far end of that range in Winter. Yuck.

Cheers.
