What sound (if any) does your clutch make when it's about to retire? I have a really screeching noise coming from my engine when I start my truck in the morning. It only happens when I depress the clutch and it only happens in the morning (around 0600). If it's later than 0900 it won't make the noise. Can anyone tell me what the deal is here? Thanks in advance! Oh, btw...I've got a 99 S-10 ext cab with a 2.2L manual.
