    Ive done some searching and the consensus is the vent line. I don't think that the issue here. The transmission has an external trans cooler. I don't use the radiators oil cooler at all. The transmission has a shift kit that was installed and modified to make the transmission function similar to a manual valve body. The fluid came out of the dipstick tube for the first time yesterday. I didn't warm the engine up much prior to my trip and probably was 1/2 a mile away from home when it occurred. Engine temp wasn't at operating temp yet. Probably 170 or so. Point being, wasn't hot. Reason I mention the not being warm yet was at stops there's the constant "saving" and "compensating" so the engine doesn't stumble and die due to not being warmed up. Every other time Ive driven the car I allowed to warm up where engine would idle on it own. Don't have a vacuum pump so cant pull a vacuum on vent line and its "challenging" to say the least to get anything near the vent tube due to 2" primary headers but ran a wire and weed-eater cord up the tube and I think it stops at the bend going into transmission. about 2-2 and 1/2 inches and it stops. Again, I think its at the bend where it stops. Don't thinks (but obviously don't know) its a restriction. I considered putting a locking dipstick on dipstick tube but think that's a band-aid and that if I have an issue, the pressure has to go somewhere and may blow past a seal or something. The fluid level was probably on the low side. I feel confident it wasn't overfilled. Right now it doesn't touch the stick. Haven't filled and tried again yet.

    Whats your thoughts?

    Assuming that it, how to unplug? Drop the pan and compressed air???? Ive heard people blow air thru and makes more than a mess is why I ask.

    Vacuum pump works sometimes, last resort 150psi compressed air, just a couple quick spurts to clear the blockage. You really should check it with a vac pump first, though.

    reach up there with a piece of vaccume line and slide it over the tube. Then blow comperssed air through it. Had the same issue and thats what cured it.
