I am having an extremely strange problem. There is a brief chirp coming from passenger side front of the vehicle which is accompanied with a momentary loss of power. It occurs under light throttle and occurs more reliably when going up a slight grade. It does not seem to have to do with the weather-ie rain. About a year ago, I had the tranny refresh and service for the judder. Approx 52k miles. Video captures it- note the flicker in the tach when it occurs. Any thoughts on what it may be would be appreciated.
