if im in to high of a gear for the speed im going.... ex. 20 mph in 4th gear.... i hear a funny noise coming from under the hood, but it seems like ive heard it before on other manual transmissions.... what exactly is it making that noise? its kinda like a gringing noise or something i dunno how to describe it but once i pick up to the right speed for the gear it sounds fine.... it also does this if im just letting the truck move on its on in 2nd gear and then if i give it a lil gas it will make that noise for just a second then it will fad away
