Expert Reply:
I would try reversing the direction of the fan on the Derale Transmission Cooler # D15960 that you have installed on your 1994 GMC Truck to see if that will yield you cooler oil temperatures.
Generally speaking coolers loose from 25 to 40 percent of their cooling efficiency when the fan pushes air through the cooler as opposed to being pulled through it. Also, depending on the location of the cooler in relation to underside of your vehicle the fan might be fighting the natural airflow direction under your vehicle.
If this does not help the situation you will most likely need to relocate the # D15960 to a different area on your vehicle that sees more airflow and make sure to have the fan as a puller.
