I could also feel the car lose power on upshifts due to the slippage even in cold weather, although it was much worse in the summer.

On monday my tensioner pulley failed, causing a crazy vibration from the engine bay accompanied by an ugly banging sound on “cold start” for about a minute.

Tommorow I am picking it up and will update you if the squeak comes back. Though I highly doubt these two things were unrelated, since the squeaking was getting worse.
Any update on this? The new pulley fix your problem?
