Now we can go back to my original thread, the reason I said to check if the truck goes into gears while it is off, and run when turned on was to check if there is anything wrong with a synchronizer. If the truck runs and goes into gears while off, most likely it's the pressure plate. It so happens that if for some reason the pressure plate loses pressure, you'll not have any gearing, also if the pressure plate comes out of aligement, there will be no gearing. One more thing, if the pressure plate is not set up with the clutch 9come in the same box), ie. you buy them separately or just change the clutch and not the pressure plate, your truck might not go into gear. I learned this the hard way and now I buy the set even if it's more expensive so they match.
