- 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.
- If equipped, remove and discard the transmission fluid in-line filter.
- Remove the transmission fluid cooler bypass valve and install rubber hoses in its place.
- To aid in attaching the cleaner to the transmission steel cooler lines, connect 2 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 tank reservoir.
- Turn on the pump and allow the fluid to circulate a minimum of 5 minutes (cycling switch on and off will help dislodge contaminants in cooler system).
- Switch off the pump and disconnect the pressure hose from the transmission cooler return line.
- Use compressed air to blow out the cooler(s) and lines (blow air into the transmission cooler return line) until all fluid is removed.
- Remove the rubber return hose from the remaining steel cooler line.
- Remove the rubber hoses and reinstall the transmission fluid cooler bypass valve.
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.
