What causes a transmission cooler to leak?
  • Heat causes oxidation. Oxidation causes a brown tarnish that coats the dipstick, transmission case and other components inside the transmission. This tarnish also causes transmission valves to stick, resulting in delayed and unusual shifting. If the fluid is pink and milky, the transmission cooler is leaking.
What causes transmission cooler lines to leak?
  • The most common transmission cooler failures are due to either a leak in the body of the cooler itself, or a clogged line caused by something flowing through the system. This most likely is from the transmission itself. If left unattended, the transmission will run low on atf which will increase the fluid temperature and cause premature failure.
What does a transmission oil cooler do?
  • The true function of a transmission oil cooler is to rid the transmission oil of excess heat. Basically, oil is used in transmission to reduce friction that is created when gears change their position.
What does the transmission cooler bypass valve?
  • The thermal bypass valve is the gatekeeper of cooling your transmission, quite literally. Depending on the vehicle, ATF will cycle out through an external cooler once it reaches a specified temperature. Once that heat builds, an internal thermostat shifts and opens a passageway to the cooler.

The oil cooler is based on the same flow-through principle as the transmission cooler. It is installed in-line with the vehicle's oil delivery system, and then the oil pump pushes oil through the cooler and back into the engine.

What happens if transmission cooler line breaks?

When a transmission oil cooler hose fails it can cause the transmission to overheat. This can be due to low fluid level from a leak or preventing flow. In either case if the transmission overheats it can stop working entirely and this condition may be permanent.
