Transmission Cooler

The transmission cooler is a small radiator that cools the automatic transmission fluid as it circulates through the transmission. It can be a separate unit or integrated into the engine radiator.

Symptoms of a Bad or Failing Transmission Cooler

  • Transmission fluid leak
  • Overheating of transmission fluid
  • Illumination of the Check Engine Light

Transmission Cooler Related Repair Advice

  • Simply draining the transmission, or removing the pan and filter, does not drain the old fluid from the transmission cooler. A fluid exchange procedure must be performed to remove and replace all of the fluid in the transmission, torque convertor, and cooler system.
  • The transmission cooler should be flushed whenever the the transmission is overhauled or replaced. Any debris left in the cooler can find its way into the newly installed transmission and cause damage.
