Ford Mustang (1999-2004) Service Manual: Transmission Fluid Cooler - Backflushing and Cleaning
1. CAUTION: Do not use any supplemental transmission fluid additives or cleaning agents. The use of these products could cause internal transmission components to fail; this will effect the operation of the transmission.
Conduct backflushing with a suitable torque converter/fluid cooler cleaner. Test your equipment to make sure that a vigorous fluid flow is present before proceeding. Install a new filter in the flush equipment if flow is weak or contaminated.
2. To aid in attaching the cleaner to the transmission steel cooler lines, connect two additional rubber hoses to the transmission end of the steel transmission cooler lines as described below.
- Connect the cleaner tank pressure line to the steel transmission cooler return line (longest line).
- Connect a tank return hose to the steel transmission cooler pressure
line (shorter line).
Place the outlet end of this hose in the solvent tank reservoir.
3. Turn on solvent pump and allow the solvent to circulate a minimum of 5 minutes (cycling switch on and off will help dislodge contaminants in cooler system).
4. Switch off the solvent pump and disconnect the solvent pressure hose from the transmission cooler return line.
5. Use compressed air to blow out the cooler(s) and lines (blow air into the transmission cooler return line) until all solvent is removed.
6. Remove the rubber return hose from the remaining steel cooler line.
