Truck started making a funny noise wed, it started grinding going into 2nd and 3rd and ic ould feel a shudder in the clutch and the gear shift. Crawled under the truck and a tranny bolt was about to fall out tightened it down and check ed the others and it quit....i thought, then today it started it again, it only seems to do it when the truck is hot, if i let the truck cool down and then take it down the road it doesnt do it. I am gonna check the tranny fluid as soon as i can get a 17mm allen wrench or hex wrench. Any ideas on what it could possibly be? The truck had a clutch installed about 3k miles ago.
