What happens if you fill tranny using bolt #2?

A better question is on my 04 STi, I had to fill from the top fill hole in the first picture in the OP's picture.

I just did a transmission drain and refill using the "Old style" bolt on the topside, think I caused any issues?

This would be great to know before morning when im suppose to drive the car! haha

I filled from top hole, but used side hole to check level.

Also found out if you use the oil dipstick, the correct fill level for the trans ends up being between full and low, dead center. So you can just pull the top one and use that as a gauge as well. Your pick. Filling is really intended from the top hole I believe. The side hole is more of a level check.

you're car is different - thats a diagram from the 08, if you have a dipstick you might not have a side filler to begin with. regardless i doubt any issue would arise from either as long as it gets down to the gears

i dont have a sti, but i do have an 09 wrx and my transmission comes with a dipstick, i was actually surprised when i first noticed it, i wonder if its something the my08 guys can buy and use.....

No it is just STi specific. My wife's 08 WRX has one, my 08 STi did not.

bummer i was hoping there was a way to retrofit the older dipstick to the newer trans

I just did mine and I thought id clear some things up in one post.

For a 08 there is no dip stick.

Use a t70 for the clutch side.
And remove both drains, and allow oil to drain.

When refilling.





Take out both 1 and 11, fill through 1 until it comes out of 11, that’s it.
I found it easier to fill through 1 as it was on top and easy to get to.

A 08 takes the same oil in the trans, center and front diff, which is all one piece, as it does on the rear diff.

And that oil is this stuff

Previous models took different stuff in the front and rear, but not the 08’s

Does anyone have a favorite oil?

I'll correct this asap. Thanks for pointing it out.
