Top best answers to the question «What is the transmission cooler»

A transmission cooler operates like a heat exchanger mounted adjacent to your car's radiator. Hot transmission fluid flows through the unit and comes in contact with a series of fins or plates. The resulting heat dissipation cools the liquid as it cycles back into the transmission.

What size line for transmission cooler?

What size transmission cooler line?

  • The size of the cooler passages in a C4 are no larger than 7/32". There is more than enough pressure to get oil through a 5/16" line to cool properly. A 3/8" line is slightly better because it has less friction but you will never notice any added cooling.
What size transmission cooler for powerglide?

Where does the fluid go in a Powerglide transmission?

  • In a powerglide transmission, a looped cooler line dumps the automatic transmission fluid at its highest temperatures (directly from the torque converter) into the gear set and clutch packs. This causes early failure of all components. BTE recommends using a high quality cooler. We offer transmission coolers from Derale.

What are transmission cooler lines made of?

Also known as transmission cooling lines, they are typically made of metal or composite aluminium and rubber hoses because they can handle the flow of hot transmission fluid.

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.
What fluid goes through a transmission 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.
