DIY: CHANGE MANUAL TRANNY OIL

[ecc_33]

drove 70 miles round trip from home to work than back. Still not as impressed as what i figured it will be. like I said I will change it again at 60,000 and try red line. When I first took off this morning it was about 40* out. It did shift amazing when the car was cold. But after about 10 miles it felt almost as if it was the old fluid. Oh well. It would be nice if it got better after a few more miles. Time will tell.

Brief necro, but wanted to thank the OP for the informative DIY guide. Drained and filled my RS 5MT with Redline MT-90 today and even after only a dozen km of testing, it feels great. Shifts are smoother than on the stock gear oil, and the entire process only took an hour or so.

For those with Tanabe DF-210's installed you can reach both the drain and fill plugs without jacking the car, but it's pretty cramped. I did have to loosen the under-air dam shroud to get good access to the bolts.

Interestingly, I loosened the filler bolt with an air tool and, not knowing that the bolt only had about 3/4" of thread on it, took the entire thing off in one swift go. The result was more than a cup of gear oil spilling out. The two quarts I added after the drain got me right to the proper fill (i.e. right at the bottom of filler plug), but it makes me wonder how I got so much oil in there before.

tl;dr, Redline MT-90 is great so far, process was simple and cheap for DIY, lowered cars can be refilled without jacking, though it is more difficult.

Yes Thanks OP!
Redline MT-90 is the BEST! GL-4 all the way!
Just did another Transmission fluid change.
I found it easier to remove the entire air box to gain access to the fill plug from the top with a funnel and tube.

Great info. But that only drains 1 3/4 qts. of fluid and there is 4.9 qts. so how do you get the rest out?

Thank you very much for this how to thread sir! Just changed my fluid a few minutes ago and it worked great!

[dan4yaris]

Excellent DIY! Just be advised, when you are filling using the vinyl tube with the funnel the oil runs very slow so be patient!

Also, you must use a 24 mm socket, there is some metal on the way when you try to remove the drain bolt. I tried with a wrench it just did not work!

excellent pics to help locate plugs.

drain plug parallel to the drivers tire!

fill plug parallel to the front bumper!

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.

Pretty sure this is it. Grey metal cap I think.

Cory, how did you clean the vent? When I removed the filler plug, some air hissed out, so apparently my vent is clogged. From the photo you posted, I can't figure out where it is. Is the vent a bolt, or simply a hole? Can it be cleaned with a squirt of compressed air?

[tmontague]

I wouldn't mind knowing where that vent is either. I have changed my trans oil at 87,000km when I got my Yaris but will be doing it again before the winter as I'm at 122,000km and I want to put synthetic in. I didn't hear any air release the first time I did it but I'd like to check it.

Driving a 2010 Hatchback, 5 door, manual with 80K miles
Came back from the dealer after replacing the axle seal, which showed some leaking. Opened the filling cap and heard the hiss so I am sure I have to clean the vent. Now waiting for the MT-90.

Thanks for all the inside info.

Hey this is a great diy but I'm having difficulty finding the fill plug is it on the bottom front by the airbox or on the side?

[Em_]

i did it my self about 2 months ago

it's in the front as you look at the engine

[ijose 845]

okay thanks! im doing mine tommorow i just wanted to make sure i got everything mapped out before i do it llol

[Hershey]

You using a torque wrench ? May want to mark one plug as F.P. ( filler plug ) .
