HI
I have a vibration/shudder that I'm trying to diagnose in my 2012 500 Pop. It only happens when pulling above 3k rpm in 3rd and 4th gear. Push in the clutch or let off the gas and its instantly gone. Seems smooth in 1st, 2nd, and 5th at any RPM and fine at highway speeds. Engine runs smooth to all rpms in neutral. It had a new clutch less than a year ago and ran fine till this shudder started last week. Since then I've replaced the motor mounts and CV joints and shafts, with no change or throwing any codes.
My next thought was to put the car on the rack with someone in it. Run it up to the gears and rpm range where the shudder occurs to see if I could find the problem from underneath. There seems to be a "safety" or "limp" mode that activates and clamps down on the brakes when you press on the accelerator in any of the gears while the wheels are off the ground,
If anyone has thoughts/suggestions on the shudder and/or knows how to disable the "safety/limp" mode please chime in. Any and all help is greatly appreciated. Thanks
