I had the transmission oil changed for the 2nd time by a Dodge dealer and noticed when I left the dealership that there was a 2 second shudder when starting out from a dead stop. That is the only time it does it, and it hasn't gotten any better or worse since. I haven't pulled my 36' rig yet, but I plan to take it back to the dealer and get his story. Any suggestions on what this is. 2003 3500 cummins with the re48 transmission.
