Dreaded Shudder or Something Else??
Just picked up my Overland Hemi 4x4. Have driven it 1500 miles to date and love it.
However, I have an issue that I am concerned with. While driving between 40 mph up to 85/90 mph I experience a slight high frequency vibration while in either sport or auto mode and in drive. When the engine goes into ECO/MDS mode the vibration is stronger, much more pronounced. When I drop the tranny into the "tow/haul" mode the vibration is significantly reduced, nearly not noticeable. I took the car to the dealer and they could not duplicate the issue. (Note: Understandable as they drove it a total of 3 miles and the nearest freeway where they can legally get up to 45 plus mph is 5 miles away. I highlited the shudder TSB to the dealer and they offered to implement the TSB to satisfy me. I am hesitant for two reasons. First I am not sure this is the "dreaded" shudder I read about and second I read in this forum where some of you have had more shudder after the TSB was performed.
Has anyone experienced a strong vibration while in ECO/MDS mode which is reduced if the drive train is placed in tow/haul mode?? If so what was done to rectify the issue? Any suggestions?
Thanks in advance for your input.
