I am not a Tech but make my living in the Auto Parts Industry. There is nothing wrong with using a trans flush machine to draw the fluid from the trans as long as the tech drops the pan and replaces the filter. You cannot "flush" the filter in your truck. It contains a paper filter media similar to an engine oil filter and it cannot be flushed. My suggestion to you is to drop the pan, clean it, replace the filter and put it back up with apprx 5 qts of fresh fluid. If the fluid appears dark or smells burned or you just want to change all the fluid, you can do this without a machine. You can use the transmissions pump to pump out one qt at a time until you have replaced all of the fluid. Amsoil's website offers step by step instructions as to how to do this and it is very easy. If you are not comfortable in doing this, take your truck to a Prof Tech and let him change the filter and the fluid.
Please do not let someone talk you into "flushing" the system without dropping the pan and changing the filter.
