High-Rev Gurgling Sound In Dash
 

Hey all. I'm curious about a gurgling sound I have in my dash. 2001 2.5L It's much louder in winter time, and when the engine is cold. Hear it less in summer and when coolant level is low. It sounds like it's coming from directly behind the central Air vents and climate controls. Oh yeah... no leaks in coolant system, just didn't check it for over a year and it was somewhat low.

I also have hesitation problems in low gears rolling thru stop signs or in stop/go traffic, but smooth otherwise. Seems like my baby doesn't know what gear to use and has a hard time making up her mind. I'm starting to develop whiplash when I drive thru residential neighborhoods!!! Anyone know any fixes for that? Trans flush? Filter Change?

Any ideas? THANKS!
