ATF Change Opinions

Recommended Posts

  • Moderators

Recommended at 90K, only have 62K on an 01 C2, ATF is 13 years old, should I replace it as a PM thing or should it be fine. I already have the parts and the expertise, so hassle vs benefit is the only issue at this time


It has long been our opinion that the factory Tip service intervals are too long.  Many of our Tip equipped customers have theirs done 40-60K mile intervals, sooner if the car is tracked.  I'd change it.

Good call on the early change, that stuff was nasty, cannot imagine adding another 30K to the scheduled maintenance, would have been 4-5 more years!


They usually are, which is why we change them earlier than the specs call for.  As I said earlier, fluid is cheap, Tiptronics are not.

I have been replacing the tip oil once every 45K. It is much cheaper than a transmission fixing cost. Also, has anyone used Schaffer Supreme 9000 Fully Synthetic Engine Oil (5W 40 grade)? I have used it once in my Boxster and the performance was superb.
