For your 2001 GMC 2500 HD Sierra, I recommend the Derale Radiator Adapter Fittings for GM # D13018 along with the Derale 16-Pass Electra-Cool Remote Transmission Cooler Kit w/ Fan, 8 AN Inlets - Class V # D15900. This unit can be mounted anywhere you have space and has an in-line thermostat to shut off at 180 degrees to conserve energy. This will be a high efficiency cooler that can be mounted anywhere.
