Ive only been able to find one older forum discussing this with no solution. I have a 2014 Ram 1500 crew cab with 20k miles. When releasing the brake from a stop, it feels like trasmission bumps into gear. Almost like you have a heavy object slide in the bed. Anyone else experience this?

 

It's a software glitch, what Chrysler says, but I got the update and it didn't get better. What I noticed is, when I have the AC on, resulting in slight higher rpm, it's almost gone. I read also in another forum, that someone took the 2-pieced drive shaft out and lubed the connections with brake pad grease and he claims it's gone.
If you don't want to start an odyssey with open end, accept it. I'm technician by my self and I say- I have a 100000 miles 5-year warranty. if it breaks down, then it will do that before 100k miles. if not- it probably lasts. At least Chrysler seems to be confident, as far as they did not really force a solution, how I've seen as I test drove a 2017, which had the same bump.
