ALLISON + COOLANT
I have a 2002 Winnebago Ultimate Advantage 40E equipped with a 350 hp Cummings diesel. I recently noticed that the engine coolant level was low. After adding a gallon of antifreeze and a gallon of water, I let it sit an hour. I then discovered the coolant level was down again, which prompted me to check the engine oil and transmission fluid levels. I found that the transmission was way overfull, telling me that the coolant is getting into the transmission.
