worn input shaft brake.... anyway to inspect you have to drop tranny

 

I still think it's a clutch stop problem. If you don't know, a clutch stop is a disc with friction material simmilar to a clutch plate, that slides over the spigot shaft, between the thrust bearing, and the pressure plate. It causes friction between them when the clutch is pushed and stops the input shaft from spinning. The gearbox have to come out to replace it. I read somewhere that a two piece clutch stop is available. Never seen one though. You will have to face the demon and take the box out.

 

clutch is dragging or the clutch brake is broken. the clutch brake is actually misnamed cus it don't brake the clutch, it brakes the trannie so that it can go into gear.

 

Now wait a minute...... you have a 10 speed and a shop tells you the harness and computer need replacing?

What tranny do you have ? ( Whats the number like RTOC 14609 B )

 

yes! its not a stop. in a truck with a peddle, when you push it down hard, you are squeezing the clutch brake ( actually a trannie brake ) thats hooked to the input shaft. this causes the 150 pounds of gears in the trannie to come to a stop so you can slide it into gear. in an automated manual with no pedal a servo motor does what the pedal used to do. if the clutch brake is broken or the clutch drags the input shaft won't stop and the computer won't try to engage the gear. clutchs can still be in perfect adjustment and still drag ( warped plates, friction material cumn loose etc. etc. .

 

Look here all other posts are crazy. Your clutch brake is out of adjustment. Your clutch maybe self adjusting but your clutch brake surely is not. Tranny does not have to be pulled to replace clutch break. If its a one piece you need to torch it out. Not a fun job. And replace with a two peice.

 

An alternative to cutting the clutch brake out with a torch is to place stick wood on each side of the brake disc and depress the clutch pedal and hold, trapping and securing the disc so you can cut though it with an air hammer and long bit. Dodging molten metal in your face gets old quick!
