CLASS RACER FORUM - View Single Post - Jerico grinds in reverse after street driving?

I have a bracket car with a Jerico that I drive on the street. I know most of you have dedicated race cars but probably the most amount of manual transmission experience out of any drag racing class. So I was hoping to ask if anyone experiences release issues after your drivetrain gets good and heated after driving an hour or so? It's a mild grind and can be stopped easily by easing into gear. I also hold the clutch in for five seconds or more to let everything spin down. When I had the Jerico pilot bearing it would grind so bad I had to turn the car off and then put into gear. I currently run a GM bronze bushing and its night and day improvement. My bellhousing is aligned to perfection both parallelism and concentric. I don't believe it to be an air gap issue either. I'm thinking that it takes so little power to turn these transmission that my pilot shaft may be dragging.
