Roger that - was thinking the _bottom_ line would drain without the pump going. Guess not!

I'm a doofus. I've always thought water circulated inside the tranny. (which would be very risky now that I think about it) So the responses didn't make sense to me. Was thinking about replacing some sort of internal cooler and I had never noticed any module that would come out of the tranny. I just looked up coolers on skidim and now realize the fluid gets pumped out and through that external cooler. Duh. So the line that I disconnected was the lower fluid line. Now why didn't more fluid come out?! Vacuum? I did check the fluid level and it was on the money.

Embarrassed,

Tom,
As mentioned, it sounds like there is a leak between the oil and water circuit in the cooler. Better check it now before you do get water in the trans. In fact, it wouldn't hurt to do a trans oil change. Water may be in there but it just hasn't circulated enough for you to see it.

Take the cooler off. Connect regulated air to one of the oil ports. Plug the other. Set the air to about 30 PSI and then stick the cooler in a bucket of water. Move the cooler around under the water to get any trapped air out of it and then see if you get bubbles.

Winterized today.. when I dropped the bottom cooling line on the tranny a few drips of transmission fluid came out. Pulled the dipstick, no sign of water in the tranny. Normal?
