    I have been told to make sure I power flush the tranny in my Dodge.Can any one tell me exactly what this is. i know what a flush of the tranny is but why is this better. Such as how it is performed, what it helps, how often to do it, and how much they will charge for it. Thanks again

    About 2/3 (or more) of the transmission fluid is inside the torque converter. There is no convenient way to drain this fluid during a "traditional" drop the pan transmission fluid/filter change. Power flushing changes all of the fluid in the transmission. The downside is you don't replace the filter in the process.

    I work in a shop that offers the tranny flush, It is a machine that is hooked up to the trans lines and is run with the vehicle running and it changes all of the trans fluid. As far as when to do the service? I do my truck in the fall before plowing season starts. and in the spring I change the filter and add 3 quarts. :)

    Make sure when you get it done they use ATF+4 you don't want anything else.

    Also, in many newer trucks, it is not required that the trans filter be changed. Power flush is a great way to go. In my many years I have never seen a good trans with a dirty filter. Kinda sounds redundant but it is true. Theoretically, your filter will only get dirty if there is an internal problem or if you get water / contamination in the fluid. Both problems can be diagnosed by looking at the fliud during a change or at routing fluid level check.

    A proper power flush will change all fluid in the trans and converter. then it will extract all fluid out of the pan via the dip stick tube so the the filter can be changed with no mess. then the amount of fluid removed from the pan will be replaced.....

    Not to say it diesn't happen that way... I just have never seen a power flush that extracts the fluid from the trans pan via the dipstick tube during a power flush. The machines I always see are hooked up in line with the trans cooler on the radiator. You fire up the vehicle and put either in Neutral (many Dodge vehicles) or in park and the trans pump in basically "exchanges" the old with the new. After that the machine is disconnected, you pay your bill, and off you go. No need for a filter replacement.
