  Q: How to Service and Repair the Automatic Transmission Oil Cooler Lines on Ford Five Hundred?

  A:

  The first step for servicing and repairing transmission fluid cooler tubes is disconnecting them from both transmission fluid cooler and transaxle counterparts. It is essential to use mineral spirits for cleaning purposes followed by automatic transmission fluid flushing and shop air drying of the cooler tubes. Using any combination of Mercon (R), Mercon (R) V, Mercon (R) SP, Motorcraft Premium Automatic Transmission Fluid or Motorcraft Continuously Variable Chain Type Transmission Fluid will result in transmission damage because only the recommended fluids can be used interchangeably. The backflushing process must begin using the appropriate cleaner solution with vigorous fluid movement through the system but new system filter installation is required when flow or contamination occurs. Three additional rubber hoses should be attached for cleaner connectivity to steel transaxle cooler tubes by using the cleaner tank pressure tube to connect with the steel transaxle cooler return tube and using a tank return hose to connect with the steel transmission cooler pressure tube which has its outlet in the fluid tank reservoir as well as connecting a rubber hose to the transmission fluid cooler tubes. Turn on and activate the fluid pump for five minutes or longer while switching it off and on periodically to move away contaminants. Turn off the fluid pump and remove the pressure hose of the fluid reservoir from the transaxle cooler return tube. Previous to rubber return hose removal from the steel cooler tube use compressed air flow to evacuate fluid from all cooler units and tubes. The installation of fresh transmission fluid cooler only becomes possible after thorough tube cleaning.
