You are getting water into the coolant. Most likely cause is a failed radiator/oil cooler.
If the coolant level keeps reducing and transmission oil level keeps increasing then the above answer is correct.
A milky color indicates that engine coolant has been leaking into the transmission's cooler in the radiator.
The reason the fluid is a milky color is that water is getting into the transmission. How you ask??? Well the cooling lines go into the radiator to cool the fluid. It is at that spot it is picking up water as the cooler inside the radiator has a leak. the best solution would be to change the radiator. You could block the fitting ports for the lines at the radiator and put an external cooler on it. YOU MUST thoroughly flush the transmission and change the fluid and filter.
Is it a milky tan color? If so, it sounds like a blown head gasket.
The transmission fluid cooled by routing it through the radiator. The fluid probably is a milky color because the radiator had failed internally allowing the coolant and transmission fluid to mix. Check the coolant and if looks milky change the radiator, coolant, and transmission fluid.
Milky Color!!
it is blue
Water or antifreeze.
all kinds!
Milky white.
Milky means that there is water in the fluid. You need to have the radiator checked for an internal leak.
Articulare cartilage is hyaline cartilage and it is a milky color.
White. All forms of quartz will have a white streak, regardless of specimen color.
