Default 2003 ATF drain & fill issue

Did my first series of drain & fills this weekend and came across a strange leak. I noticed ONLY during the refilling stage, that somewhere between the dipstick hole and the pan, I'm losing a bit of fluid that finds its way on my garage floor. I did not lift up on the funnel during, nor did I overwhelm the funnel with fluid. It was a pretty slow pour both times. Maybe a hole in my dipstick tube?! Anyone?

Could be not pouring slow enough. I had the same thing happen. It's a really small tube with an angle. Backs up quickly

The same thing happened to me. I probably could've been a little more gentle with my filling technique, but wasn't too worried about it when I saw the small pool of tranny fluid in my garage. I just wiped off the undercarriage of the car and floor, and went about my merry.

I'm sure it's just coming out when you're pouring.

I'm quite conservative and am a firm believer that unless we are the original owners and have replaced trans fluid from the onset..... let sleeping dogs lye. Our transmissions are quite robust and after 120,000 miles my fluid is bright red... Not touching it....

Yep, you guys were right. I did another d & f this weekend, and slowed the pour down to the point where any slower the fluid would run down the side of the bottle. Guess that's the trick for anybody considering this procedure.

Awesome. Yeah for my last drain and fill I actually got a fluid pump and some rubber hose and connected that to the bottle. I then ran the hose a few inches into the dipstick. Very clean, and not dribbling out. You live and learn!
