Transaxle Cooler and Line Flushing

If there has been a mechanical failure within the torque converter or in the transaxle itself, the fluid becomes contaminated and circulates throughout the hydraulic system. This includes the cooler for the transaxle inside the radiator and/or external cooler. The cooler and the lines connecting the cooler to the transaxle must be flushed before being connected to the newly repaired or replaced torque converter or transaxle. If the system is not flushed, the new components will become contaminated with the old fluid. The proper method for flushing is reverse flushing the system.
