    That looks like a good deal. It would pay for itself after 6 or 8 jobs.
    I have always wondered if it's better to change the fluid like this or replace the filter.

    looks like a waste of money for two reasons:

    #1 its at harbor freight

    #2 If your tranny needs to be flushed, it needs to be fixed.

    IMO kinda like changing your oil without EVER changing your oil filter. :roll:

    It also says changes fluid. It's pretty common to use a filter buggy on heavy equipment hyd system. Of course in some cases your talking about over 80 gallons of fluid so it is cheaper to use the filter buggy, change the filters a few times before you completly replace the fluid.

    I don't agree that if it needs to be flushed it needs to be replaced. If their is something wrong and you think you can flush it to fix it then it's too late, but to just have it serviced is another thing.
    I just had my allison trans fluid and filter change at the GMC place. $225 :shock: My trans does not have an internal serviceable filter. It's an external spin on.

    I agree with changing the filter every time, the way I would be using it is droping the pan changing the filter refilling the pan & using the machine to run clean fluid through the trans & converter to remove all old fluid from trans. And yes changing the filters every 50 min will extend trans life. I deal with a lot of high mile vans & pickup trucks that get an excess of 250k on trans in city use. maintenance is everything!

    No knowledge on this subject, but how can a flushing machine flush out the converter? i thought you had to fire up the engine to get the fluid out of the converter, or as some converters have a drain plug. I hate talking about transmissions, my 1993 duelly with 4L80E with shift kit (tow vehicle) has 197,000 miles and the planaters have been whinning for the last 50,000 miles.

    That's good to hear, at my age and not knowing how much longer i'm going to be racing i really don't want to buy another tow vehicle.
