I've got a 2008 3500 6.7 L. The only things done to it are deletes and EFI BY RYAN tuner. I had the pan filter fall out trick happen last week and now it doesn't want to stop at important places like stop signs, stop lights, in my garage places you really want to stop. It is the 68rfe and It takes me throwing it into neutral so that I know that the transmission/torque converter won't want to keep going and push me into a wreck.....No clue what it is Never had this problem before. On top of that since getting it out of the shop it wants to jump forward and then lag a little when taking off from standing still as well. If anyone can help me I'm all ears.......
