    I'm going to change the filter and fluid on my truck, I just need to know how many quarts of dex 6 I need to refill after the change. I've searched and can't seem to find anything.

    I also need to know if the pan gasket is one of those nice reusable types or will I need to replace it.

    Truck has 45k on it and the trans has never been opened.

    Just a suggestion but why not do a fluid exchange and get all the old fluid out and replace it with new.
