DIY: CHANGE MANUAL TRANNY OIL - Toyota Yaris Forums

CoryM · 04-09-2012, 01:57 PM

A suggestion to all owners, but specifically while doing this job:

Make sure your vent is clear as well. The transmission has a vent on it to allow for the expansion of the oil/air inside. Otherwise the seals have to deal with the pressure and will eventually fail. These vents often clog, and mine was plugged when I got the car with 38000km on it. A good indicator it is plugged is you will hear a hiss of air as you open the fill plug.

I can't recall exactly where the vent is on these cars. iirc it's just behind the shifter. A little white(?) plastic knob that you twist and wiggle a little to free up any junk.

I'll try to find a picture.

Cheers.
