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.
