Can I identify when my transmission fluid should be replaced?
Yes, refer to your vehicle owner’s manual for change frequency and replacement fluid type. Also look for signs of trouble or poor performance which may be a sign that the fluid needs changing.
Is there an average interval between transmission fluid changes?
No, the fluid change interval is highly dependent on your driving patterns. Refer to your vehicle owner’s manual.
Does my transmission fluid need to be changed as regularly as my oil?
No, transmission fluid is designed to last much longer than your motor oil. Refer to your vehicle owner’s manual for recommended change intervals.
Are there common causes of transmission fluid contamination?
Yes, most contaminants come from inside the transmission, metal particles and degraded (aged) fluid will most commonly be seen. In extreme cases engine coolant may be present and if so the transmission fluid must be changed immediately.
Are there preventative steps I can take to minimize contamination?
Yes, monitor the appearance of the fluid every six months and know when your next fluid change becomes due. Changing the fluid at the mileage that meets your driving cycle is the best way to minimize contamination.
Can I identify which transmission fluid(s) are applicable/appropriate for my vehicle?
Yes, refer to your vehicle owner’s manual for the specific fluid for your vehicle.
