CAUTION:
If transaxle failure exists, oil cooler must be flushed and torque converter replaced. If vehicle is equipped with 2 oil coolers, one in radiator tank and one in front of radiator, flush oil coolers separately. DO NOT
attempt to flush both oil coolers at one time.
- Disconnect oil cooler lines at transaxle. Using hand-held suction gun filled with mineral spirits, force mineral spirits into oil cooler return line until mineral spirits flows from oil cooler supply line. See Figure .
- Continue flushing oil cooler until mineral spirits is clear and no sign of contamination exists. Once no contamination exists, apply compressed air on oil cooler return line in light applications until remaining mineral spirits is blown from oil cooler and oil cooler lines.
- Pump at least one quart of Mopar ATF Plus Type 7176 through oil cooler to ensure oil cooler is free of mineral spirits. Replace oil cooler if fluid does not flow freely through oil cooler.
