Don't think it would solve your problem. The delay valve limits how fast the clutch will engage, which some people don't like. So out it goes.
Any idea what oil is in the transmission? Some people use thinner oil in cooler climates, such as RedLine D4 ATF. Apparently it shifts smoother when it's cold.
Your throwout bearing (translation: thrust bearing) might be on its way out. How many miles on the clutch?
Engineers do it with a torque wrench
