Also think about your other components. Your axles, transfer case & transmission all have oil and air in them. When you drive it heats up and expands and when driven through water, it contracts. There are air vents and vent hoses that allow for this otherwise the seals would suffer. If the vent hose is under water as the cooling takes place, chances are water will be drawn in. Especially bad for an auto tranny.
