Pump Inlet Flush Machine in Louisiana?

I want to service my automatic transmission, and I am looking for a shop with a pump inlet flushing machine, as opposed to the flush machines that attach to your transmission-cooler lines, this type of machine replaces virtually all of the fluid, and uses the transmission’s own pump as explained here:

I’ve called all over BR and NO, and I have not found one of these machines.

Any help greatly appreciated.
