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.

The reason I took it to be flushed was so all the fluid, ie; cooler, convertor and pan could be changed, but almost $300 is redickulus (sp on purpose).

Transmission flushing is another one of those revenue generating services. All of the invoices I've seen for it have had between 20 and 30 quarts of transmission fluid listed in the parts list with labor in the $90 to $150 range. I've read in several of the automotive repair trade publications where some manufacturers are saying "do not flush" their transmissions. Probably a reason for that.

Well... I could see it on heavy equipment such as Rabbit stated for example.
but it IS "Harbor Freight"... not exactly a stellar name...
I may not be an expert here, but I am pretty sure that I could buy a cheap fuel pump, get a few fittings/hoses, & make my own flusher for less than 50.00. Then I would just pour in the new...
Couldn't be too hard....
I hear of people doing this to cool down trans fluid at the strip between rounds...

There are different types of machines. I personally own a T Tech machine and know the people who first developed it and built the first generation. I used it on my 96 Tahoe and it went 204k before i traded it in and the 4l60e was still shifting perfectly. This is considered a fluid exchanger. The fluid is moved by the trans pump so yes the vehicle is running. The benefit of this is that the fluid is forced back in with the same pressure that is normally present and as the old fluid is forced into the machine the new fluid is forced back into the machine so it never is run low. Thats how the valve body and converter are cleaned. A flush machine can be one with a seperate pump that a tech dials in to match the pressure out of the trans which leaves you depending on their diligence. As far as the filter goes, i changed it every 30-40k and i always felt if you kept the fluid clean the filter wouldnt need to be changed as often.
