The Toyota Tundra Transmission Oil Cooler helps in controlling the heat of the transmission fluid when driving under extreme conditions and maintains the oil in a viscosity that does not allow thermal deterioration. It acts like an oil to water heat exchanger that is connected to the radiator circuit and allows the fluid to warm rapidly and then radiates any excess heat to engine coolant. The Transmission Oil Cooler directs pressurized oil via internal passages with the coolant flowing around them and forms a continuous heat transfer process. When the Toyota Tundra is applied in situations that are characteristic of the model, like towing heavy trailers during hot weather, stress may cause the temperature to exceed a safe range. The cooler limits these high temperatures and keeps the lubricant film constant. Shared coolant flow implies that the Transmission Oil Cooler will be susceptible to corrosion or clogging on the water side, which can reduce its efficiency and may cause oil and coolant mixture. The factory Toyota Tundra Transmission Oil Cooler is sized for normal duty but is capable of approaching its capacity during extreme load, even though it is the main protection. Regular maintenance of the cooling system facilitates the Toyota Tundra Transmission Oil Cooler in maintaining a stable temperature.
