ATF Information:

In most Automatic Transmission designs it is not possible to fully drain and therefore to completely replace all the ATF that is in the system. This is because Torque Converters, ATF Cooler and Cooler Connecting Hoses can not be conveniently drained.

If this is the case with your vehicle, than only the fluid that is lost when replacing the Automatic Transmission Filter should be replaced with SynLube™ ATF each time that the Filter is being replaced. This service should be performed every 30,000 miles or every 3 years.
