    There is an oil leak from a Slave Valve and Tower. The Breather is new. The slave kit with a pin and o-ring is new.The temperature of the transmission under load is 175-180 F. The main thing that confuses me is that the oil is coming out under a slave valve and tower but not from a breather. What do you think?

    Shift tower does have a gasket to seal it to the shift bar housing. Could it be coming from there?

    I had one leak from somewhere up there. It was covered by warranty as Eaton forgot to torque down a few bolts on a cover.

    I did change a tower
    I did change a shift tower but it still coming out under a slave valve (splitter box). It looks like it have an excessive pressure but instead of comming out from a breather it comes out from a under slave valve.....

    Those A-5000 slave valves are cast aluminum. I suppose it could crack and leak, but ive never seen one do that.

    But what i have had happen, is a crack on one of the oil line welded connections on the oil cooler. The syle oil cooler that bolts up on top of the shifter bar housing. Oil ran down and i though i had a leak at the slave valve.

    Not sure if you got the water cooled oil cooler on top, but if you do, you might give it a look.

    Pull the vent and make sure it's not plugged.
