Title: Overfill ATF?
Post by: Danish on December 05, 2008, 05:55:13 PM
Hey guys-

Is it a bad thing if I slightly overfilled my transmission? I was low on it and put about a half quart in and now I think I might have put just a little too much....

Also- it feels like the car is shifting smoother. Is this possible or am I imagining things?

Yes, new trans fluid will always feel smoother if your car has more than 90k on it or so.
Also if it wasn't more than a half pint or something it's probably OK.

Thats what I figured - I know that adding too much engine oil can cause frothy oil from the crankshaft shipping the oil but I had no idea if the same would hold true for ATF

Thanks man

If you were low and added 1/2 a pint you're probably fine.  If you'd added a quart or more then I'd be concerned.
