Question:

I have a Silverado 1500HD, I am looking at putting the Derale 13504 on my to help cool the transmission while towing, I am told by my local mechanic that I can over cool my transmission, would the 13504 still be the good choice? I live in Idaho and the temps can get down to freezing for about a month every winter, and I wont be doing any towing during that time of year.

Expert Reply:

Transmission fluid cannot be overcooled. But what can happen is that in cold temperatures it takes longer for it to warm up. All you would need to add is a cooler thermostat, # D13011, which will bypass the cooler until the temperature of the fluid gets above 180 degrees.
