Default Overfilling Transmissiom Fluid

I was just wondering, since I think I overfield my Tranny a little more than .5 quart when I changed it. Is there any downfall if I was to keep it that way or should I drain it?
Thanks,
John

I think I might have found the answer, but any other thoughts are welcome.

Thanks
John

You don't want to overfill your gear oil. All that extra oil makes the transmission work harder, puts more stress on the syncros, etc..

Go to an AutoZone/Advanced Auto Parts/etc., get yourself a transfer pump (~$10), slip the "IN" hose into the transmission fill tube, and pump out the extra gear oil into a container.

Re-check fluid level.

If you took out too much, add some back, a little at a time until you get the right level.

You can pump it out through the fill hole as Jack mentions. I would just for piece of mind.

Too much leads to foaming, and less protection.

I've found that re-filling with about .5 quart less than total capacity shows as "full" on the dipstick. Either the capacity is wrong, or more likely, not all the gear oil drains out. When I overfilled mine, I just put the gloves back on, and unscrewed the drain plug and let the new fluid drain into a new oil pan. Then I added more slowly the second time. I've also found it helps a LOT to do this chore in warm weather or a heated garage. The stuff is so thick at cool temps that it takes forever to pour...

^^ and forever to slide down the fill tube so you can get an accurate dipstick reading. in a garage @ ~40degF i had to wait around fifteen minutes (every single time) before i could get a good reading to determine whether i needed more or not.

What is the Tranny oil capacity for an 02 wrx manual... I am pretty sure i overfilled mine to because i didn't wait long enough before i checked it. Now shifting particularly into and outof 1st and 2nd feels really rough at least untill the car warms up. So i am just going to redo it and want to know the correct amount so i don't screw up again.

Fill it until the dipstick reads full. Start with about 3 quarts and then add in small increments until it reads at the proper level. Also, what fluid did you use? That can have a big influence on how the transmission "feels" after a change.
