Hi All, It's overdue for me to take the car for the engine oil change service. It's now at > 40000 miles. I was going through the maintenance manual and all my prior records to figure out what is supposed to have been done by 40000 miles and what I have actually had done (I usually go to the dealer and tell them what I need, which per my records has been only engine oil and filter changes, and tire rotations so far. The dealer has also recorded that they checked fluid levels, although afaict they haven't topped/replaced any other fluids thus far). So...I was expecting to see mention of ATF change to be required by my current mileage, and therefore was surprised to see the maintenance manual from Toyota does not state explicitly to replace the ATF ever! Only "Inspect and adjust all fluid levels" (which my dealer's service dept has been recording) and "Check ATF". Question is, is there indeed no stipulated interval by which to replace the ATF in the 3rd gen/2010 Prii/Priuses? Also noticed that the inverter/coolant fluid needs to be replaced at 100,000 miles, which is cool. I was expecting to do that every 60,000 miles... Thanks in advance for all replies!
