I have a 2004 Prius 245k Black Nav Package Scratch on passenger side from parking lot Recently it started shuddering when in park AND charging the battery Battery still charges when engine braking and slowing down Initially thought it was a misfire, however it only shakes when charging Currently drives, other than the shakey charging Mechanic told me it was the "hybrid coupler" or transaxle damper, which I guess it kind of like a clutch for the system. Based on the repair price of $1600 I would like $1,500 I am located in the NW Burbs of Chicago Regards, Jin 224-404-1004
