In the last week or two i've developed a chirp during shifts. it only seems to be apparent when the car is cold and going from 1st to 2nd or 2nd to third. Anyone else had this? I searched but i'll i'm seeing is grinding noises directly related to shifting noises. Thanks for any replies.

You have not given enough information. If you are talking about shifts during hard acceleration, the obvious candidate is wheel spin. If you are talking about shifting during routine acceleration on the street, it depends on when during the shift the noise occurs as well as your shifting technique. For example, if the noise occurs during the shift coincidental with the throttle being lifted the noise is likely from the drivetrain e.g. from fatigued springs in the dual mass flywheel, weak motor mounts, or contamination of the clutch disc. On the other hand, if the noise occurs during the shift while the throttle is partial depressed but the clutch is completely disengaged (pedal on the floor) engine components could be the culprit e.g. the serpentine belt or the power steering pump.

Occasionally mine does that shifting into second when it's really cold. It happens right as I move the shifter into gear with no gas and clutch fully depressed. Is that what yours does? It's been a couple months since it's happened so I might be forgetting what it sounds like.

Also, mine will chirp into first if I'm standing still like in a drive through or at a stop light. Not sure if it's related.
