Transmission Fluid Cooler Backflushing and Cleaning: Material
MATERIAL SPECIFICATION
| Item | Specification |
|---|---|
| MERCON® V Automatic Transmission Fluid XT-5-QM (or XT-5-QMC) (US); CXT-5-LM12 (Canada) (Early build vehicles) |
MERCON® V |
| Motorcraft® MERCON® LV Automatic Transmission Fluid XT-10-QLV (Late build vehicles) |
MERCON® LV |
NOTE:
The use of any transmission fluid other than what is recommended for this transaxle will cause transaxle damage. Refer to the MATERIAL specification and/or the transmission fluid level indicator for the correct fluid. Use only clean transmission fluid designated for this transaxle and torque converter being serviced.
NOTE:
Do not mix Mercon® V or Mercon® LV transmission fluid. This may cause erratic shift feel, erratic shift timing and/or transmission failure.
NOTE:
Transmission fluid application:
- Early build vehicles require MERCON® V
- Late build vehicles require MERCON® LV
NOTE:
Transmission fluid cooler backflushing will be carried out using the Turbo-Tank Heated Cooler Line Flusher. Follow the manufacturer's instructions included with the machine. Test the equipment to make sure that a vigorous fluid flow is present before proceeding.
- Check and top off fluid level of the Turbo-Tank Heated Cooler Line Flusher tank with transmission fluid.
- Allow the fluid in the flusher 15-30 minutes to heat up to 60°C (140°F) before using.
- Install the line adapters on the transmission fluid cooler tubes.
- Attach the flusher's red line to the transmission fluid cooler pressure tube quick disconnect fitting.
- Attach the flusher's blue line to the transmission fluid cooler return tube quick disconnect fitting.
- Follow the equipment instructions to purge the transmission fluid cooler tubes and transmission fluid cooler prior to starting the flushing procedure.
- Allow the transmission fluid cooling system to backflush for 10-15 minutes, then flush the transmission fluid cooler in a normal flow direction for an additional 10-15 minutes.
- Clean the transaxle mounted fluid cooler tubes and the thermal bypass valve by hand.
NOTE:
The FRONT transmission fluid cooler tube on the thermal bypass valve is the transmission fluid cooler pressure tube.
