    How far do you go on an oil change? I go between 5000 and 7500 miles. Just curious as to how often you flush the tranny (mileage wise).

    Why are they removing the internal filter in the first place? Allison says to change it only on an overhaul.

    yeah, really?

    If its like any other internal filter you gotta tear the tranny apart, which means out of the truck and at a transmission shop..

    thats alot of un needed work imo.

    I change mine every 3-4k depending on the season in the summer 3 in the winter 4.
    So probably about every 10k
    Ill be changing it more once i get my new sun coast stage 5 and start running the synthetic fluid.
