I have a 2005 t&c. No noticeable issues as of yesterday, however I am taking a trip so I had the oil and trans fluid changed and new spark plugs and wires. THAT'S ALL. I can not even drive the van now. It makes a bad shuttering and vibration when in park, when you change gears you can hear it and the shaking/skipping gets worse. Im at a loss for words to be honest. Any ideas?
