Hey guys, kind of a noob question here.

I was sifting through threads on here and read that if you check your atf on a cold engine the fluid line should be anywhere from 10-30mm below the minimum line(if I'm remembering correctly.) So I checked and double-checked it cold but the level was probably 1/2 inch above the max. Seemed like good coloration though. So I took it for a drive, 15 minutes or so, and checked twice again. This time I got absolutely nothing on the dipstick unless it morphed from red to clear. At first I was ready to drain some fluid and now I guess I need to add more?

Like I said, kind of a noob question, but it's been hesitating while shifting so I figured I'd make sure fluid levels were where they were supposed to be before I started looking at other things.

Thanks for any help.
