I'm assuming its the transmission.. I have a 4.2l manual transmission. Whenever I let off the clutch and hit the gas it sounds like birds chirping, particularly in first and second gear. I just had a brand new clutch put in 6 months ago. It is fine at idle. Has anyone experienced this. Or have an idea of what it might be??

 

It also could be the u joint...

 

It's not the u joint.. Anyone??

 

Drive at the right speed where it syncs with whatever music you're playing.

Don't worry, be happy.

 

Flywheel, engine mounts?

 

Don't have a clue, just trying to bump your thread.

Hope it turns out for you.

 

PUT SOME GREASE ON IT that usually fixes noise

 

Check the slip yoke in the transmission tail shaft, grease it....

Does this "chirping" occur right through 1st and 2nd?

Could it be the tranny mount? I don't know if it's an initial chirp, or continuous through the gears...

Is it the serpentine belt? A dry pulley?

Something like this is hard to diagnose without hearing it, or without enough information

 

it occurs when I'm letting off the clutch and giving it some gas... only 1st and 2nd gear it's a chirping sound.

 

Probably a bad surface on the flywheel, how bad was the clutch disc worn when it was replaced?
