Transmission Fluid Cooler - BACKFLUSHING And Cleaning
WARNING: This page is about a different car, the 2003 Mercury Sable and 2003 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
- Carry out backflushing with a suitable torque converter fluid cleaner. Test the equipment to make sure that a vigorous fluid flow is present before proceeding. Install a new system filter if flow is weak or contaminated.
- To aid in attaching the cleaner to the transmission steel cooler tube, connect two additional rubber hoses to the transaxle end of the steel transaxle cooler tube as follows:
- Connect the cleaner tank pressure tube to the steel transaxle cooler return tube.
- Connect a tank return hose to the steel transmission cooler pressure tube. Place the outlet end of this hose in the solvent tank reservoir.
- Turn on solvent pump and allow the solvent to circulate a minimum of five minutes (cycling switch on and off will help dislodge contaminants in cooler system).
- Switch off the solvent pump and disconnect the solvent pressure hose from the transaxle cooler return tube.
- Use compressed air to blow out the cooler(s) and tubes (blow air into the transaxle cooler return tube) until all solvent is removed.
- Remove the rubber return hose from the remaining steel cooler tube.
