This morning I started re assembly, the trans breather is in a VERY inconvenient location, But with a piece of rubber hose sealed to the dipstick when I blow air into it I can hear and feel the vent working, and it builds NO pressure, also no I didn't use the compressor, just my breath, it's very clear, also It looks like not so much a hose as it's a hard line with a check valve on it much like a factory rear end breather. tight to the bellhousing at about the 12 O'clock position on the top of the trans.
SO WE WILL SEE.
Thanks for the replies.
