I recently been hearing a strange noise when I stop and have the windows down. It coming from the back of the truck like somewhere from the transmission back, its like a high pitch sound almost like a high power fan like a ZZZZZZZZZZZ! its been really hot lately where I live so can it be some kind of a tranny cooler or is somethin back there gonna blow up? any suggestions or comments are greatly appreciated and if you have any questions for me about the truck i will anwser them ASAP, I would really like to figure this out! maybe its normal?? Oh its an 2000 Chevrolet Silverado 4x4 with 100,000 miles! thanks for ur time.
