Re: Transmission Mods
By the way, I have created an Excel spreadsheet to calculate the accumulated fluid age before and after a partial ATF drain and fill as well as the average accumulated fluid age over the most recent interval. You enter the total ATF capacity, the capacity that is changed out in a partial refill and the mileage between partial refills. You see that the accumulated age and the average age for an interval converges over time.
So what matters more, the maximum age of the fluid or the average age of the fluid over an interval? For example, if you did a full drain and refill and you did it every 30,000 miles. The maximum age would be 30,000 miles and the average age over the interval would be 15,000 miles since the fluid starts out at zero mileage after the change. So is it that we don't want the maximum age to exceed 30,000 miles or is it that we don't want the average age to exceed 15,000 miles. I ask because I can add a macro with a button to automatically calculate the OCI to achieve either target.
Does anyone have an accurate measure of the amount of fluid drained if the car is put up on a lift, level?
