I was getting a load of seed yesterday and when I got the T800 on the highway and was going 60+ I could hear an intermittent swooshing sound that almost sounded like the fan blowing extra hard for just a couple seconds, it would sound normal and then a few seconds later the same sound. This is in a 15 speed and in all the lower gears I've never heard this sound. I don't really notice the sound in 15th at a lugging speed going slow but right around that 60+ speed I can really here it pulsing/ vibrating on and off. I was thinking maybe the high speed with the wind was throwing the fan off balance or something? Or maybe something transmission related?
