Oil coming out of transmission control valve breather SN:AT14E00586 Diesel

Greetings all,
This machine has developed a leak at times when operating with oil coming out of the trans control valve breather. I've confirmed that the oil level is correct, main pump pressure is in spec (140-180 psi as I recall), and I've removed the suction screen to confirm it was clean. I can see foam and bubbles when I look in the dipstick tube when running but I also see them in a sister truck that does not have this problem. Has anyone seen this problem before?
