I just bought a 2005 LX Chrysler Town and Country van (3.3 liter, v6, 4 speed transmission). I really like it. I have noticed that the transmission will have a slight shudder or shake when you first reverse up a hill (must be stopped on the hill). Once you are rolling backwards for a moment, it stops. The shudder is worse at the beginning if you reverse slowly up the hill to start. This does not occur when reversing on a level grade or on an ever so slight uphill grade. The transmission is very smooth in all other operations. Is this normal? Should I be concerned or is the van just "breaking in". The van has 98 miles. Thanks for your response. I wonder whether to contact the dealer or if I'm being picky.
