When to Use / Replace?
Use this cleaner during routine transmission service every 40,000-60,000 km or 24-36 months to remove buildup before an oil change. Ideal if you notice rough shifting, delayed engagement, or slipping gears. Add at operating temperature, idle engine 10-15 minutes while shifting through gears, then drain old oil and filter. Replace ATF every 50,000-80,000 km depending on driving conditions.
