I have a 2005 Silverado 2500HD 2WD with the NV 4500 5 speed. is there a reoccuring problem with the hydraulic clutch system? I lose pressure in my clutch constantly, occasionally I have to pump the clutch to build up enough pressure to shift and I have to refill the resevoir every couple days but i cant seem to find a leak anywhere. Obviously it can be extremely hard to shift. As my daily driver I'm hoping I can fix this somewhat inexpensively.
Thanks in Advance.

 

well there must be a leak some where. thats why you are losing pressure. you could also have a bad master or slave on the clutch. you could put a big piece of cardboard under it and pump the clutch over and over or a long time till you find the drips then you can find the leak. I would do this with the truck not running in case the fluid in falling on somthing hot.
