Thanks Wrenchbender,
I forgot to say that when this happens, I can put the truck in 4th, release the clutch, and the truck just sits and idles, no grabbing, lurtching, or stalling. However, when cold, it trys to move and dies just like it "should" durring this test. I think I filled the tranny too full last time and that's when this all started. Do I just need a new clutch or is there some way to prevent this from happening again?
