Yes in a sense, the transmission has an oil pump and cooler that I run manually. When I speak of the SMG I mean the hydraulic or control system for the transmission. The theory is that if the trans is cooler and the SMG system is mounted to the trans it will run cooler. This is of course just one big band-aid for the SMG which needs overhaul or replacement. All of my problems(codes) are hydraulic(SMG) related. I have yet to read of a problem with the transmission/gearbox.
