WHY IS TRANSMISSION FLUID MIXING WITH THE ENGINE OIL

1992 Mazda b2200 • 90,000 miles

Inside the Breather there is transmission fluid and has to add transmission fluid every 2 days. Left side of the engine is coated with Transmission fluid around the vacuum lines. Underneath the truck it is dry with no signs of Transmission fluid. Feel like it is a vacuum problem but not sure. The transmission fluid is mixing with the engine oil. Do you have any ideas what is causing this and what we should do?

Check if the transmission has a vacuum modulator if so the diagphram is leaking and the vacuum is sucking it back to the engine-

Sounds like the vacuum modulator is sucking transmission fluid.
