I Have A 2000 Sebring 48K,Driving Sometimes Not All The Time,When You Lift Off The Gas Pedal,You Feel A Bump,Its Like The Trans Came Out Of Lock Up,It Doesn't Do It All The Time,Had The Service Tech Out For A Drive,With His Computer,He Felt It But The Computer Didn't,He Checked To See If They Had A Notice On It.There Is No Notice,So He Says There Is Nothing He Can Do,And He Wouldn't Know Where To Start. Any Extra Info Would Be Greatly Apprec.

 

well, first off, lay off the shift key

second, is it only when you let off the gas? If it was both when you decel + when you hit the gas, I'd say it was a loose motor mount
