Is there some sort of 'breather' on this transmission? If so, where is it located and does it clog up easily? Inquiring minds need to know.

I quoted this from Jim and Tere's other post. I do not know what Jim was smoking when he titled two topics the same.

What would make a small amount of 'oil' or maybe 'atf' drip out of the vent tube? Overfilling? Right--checked Chevy manuals and it said to check with engine running and tranny in PARK. If the fluid was 'cool'65 degrees F to 85 degrees F, the level should be 1/8" to 3/8" below the ADD mark. If fluid warm, level should be close, either a little above or below, the ADD mark. If hot--too warm to handle comfortably, level should be between the ADD and FULL mark. If it's too high, how does one take a little out without dropping the pan? If level is ok, what would cause the dripping? Cross leak in the pump? Of course I don't know what a cross leak in the pump even is. If it's just leaking a little, what to do?
Thanks
Jim

If too full, you can suck some out of the dipstick tube with a suction pump and a smaller tube.

Trans temp gauge might be a good thing at this point. If it is getting hot enough to boil out this is not good. If temps are normal I wouldn't worry too much.

I assumed he was just enjoying the fumes from ATF leaking down his exhaust.
