    Flushing, depending on your mileage, is pretty much frowned upon for your slushbox. Again, just to start the discussion...

    NB: do a quick search

    Some info here:
    When the transmission fluid is changed, even when the pan is removed, not all the transmission fluid is replaced. Some of the transmission fluid is trapped in the torque converter, some is in the valve body, and some is behind pistons, accumulators, and so on. On most transmissions we're lucky to get 1/3 of the fluid out when draining using conventional methods. If the fluid looks brown or black before a drain and fill, it will still look bad after a drain and fill. That is the problem this machine addresses. It replaces 99% of the transmission fluid in one servicing.

    First a set of hoses are attached in series with one of the transmission cooler hoses. A cleaner is added to the transmission fluid and the transmission is run through the gears for a while. This help to remove sludge and varnish from the inside of the transmission. Next all the fluid is sucked out while the machine adds the exact same amount of new fluid. After this is done we add a transmission fluid conditioner that helps to prevent sticking valves.

    You can avoid ever having to use this machine (the flush is 5 times more expensive than a drain and fill) by changing your transmission fluid at least every 15,000 miles.
