i have had a predator on my truck since new on th 45 hp setting only, never pulled heavy loads but constantly pulling something. i have 176000 miles on it and today i was unloaded and thought i could hear a whining noise, i pulled over and looked under my truck and noticed i was also leaking fluid but only about a quart low. also the fluid is discolored and doesnt smell burnt up but does have a diffrent smell to it. the leak is coming from somewhere on te drivers side back toward the rear. the leak doesnt bother me as bad as the noise, it really makes me nervous. can any1 give me some input
