Many things, but a clutch bearing seems likely.
Does this happen when you come to a complete stop or while you are coming to a stop? Is this Truck Automatic or Standard? Brake booster could be something, Torque Converter Clutch Valve not disengaging(Automatic).
There isn't any linkage, it has a cable, check to see if the cable is loose. There is a U clip that holds the cable in place,if the U clip is in place and there isn't any slack in the cable, it could be your tranny. Is the clutch disengaging? If when you push the clutch in the engine can be turned over or the car can be pushed, it is not a problem with the clutch.
A slipping clutch.
If it doesn't move if in neutral, then it could mean the cable needs to be adjusted, or the clutch plate needs replacing.
If it will go into gear when the engine is off but not when the engine is running, the clutch is not disengaging. It could be the clutch, possibly warped or put in wrong, or it could be the hydraulic clutch mechanism.
yes hydraulic could cause this also the clutch pressure plate could be collapsed
engine flooding. low battery. cold weather. try putting the holding the clutch down as you start the car as this takes some of the pressure off the engine
It could be the clutch safety switch. Does the engine crank and not start, or is it not cranking. If it cranks, then no, it could not be the clutch. If it won't crank then you can climb under the dash and look for the switch that closes when the clutch is pushed all the way to the floor (big white plastic switch). This switch has two large wires going into it. You can unplug the switch and jump the two female connectors in the wiring harness that led to the switch. A large paper clip works, but don't let it touch anything metal while you're cranking the engine. If the engine now cranks and starts normally, the switch is bad and needs to be replaced. Hope this helps.
Trouble code P0743 means: Torque Converter Clutch Solenoid Circuit Electrical
could the tranfercase cause the clutch too hang up or is it the clutch slave,that could be hungup..
Because the clutch doesn't apply power
Why don't you take it to a mechanic before you ruin your truck by riding the clutch? The chattering could be engine knock because your engine is out of tune. When you ride the clutch, the clutch slips and puts less strain on your engine as you are burning out your clutch.
