I did a drain and fill on the ATF on my Honda Civic today. Thought I would be smart and catch the old ATF in my drain pan and dump it into an empty 5 quart oil jug, then use the jug to measure how much drained out, then put that amount back in. I drove the car a few miles to get the ATF hot, put it on jack stands so it was level. It took about 10 minutes to lift the car, then I checked the ATF dip stick, it was just at the low end of the hash mark area. Fine, I set the drain pan under the car, removed the drain plug and the ATF gushed out all over the place. Most of it went in the pan, some of it splashed out on the floor and on me too. Big oily mess to clean up.
I still put the old fluid that was in the pan into the oil jug, it was just over 2 1/2 quarts. I looked at that, then tried to guesstimate the amount spilled on the floor and figured the total had to be close to 3 quarts. So I put in all 3 quarts of Honda DW1. My Honda owners manual says a drain and fill takes 2.7 quarts. I drove the car a few miles and let it sit maybe 3 minutes, checked the level and it was showing about 3/16" above the full hot mark.
On the test drive, the car ran very well like always, shifted great, much better than before, had no transmission problems at all. There were no bubbles on the dip stick when I checked the level, no evidence of aeration at all. I think I slightly overfilled the ATF by maybe 1/4 of a quart. Question is, would it be best to drain some ATF out or leave it as is? I appreciate any help.
