Started my '20 Ram 2500 Tradesman up and heard a loud bang near left front side of truck. A few minutes later going down the road from my house the truck would NOT shift out of 1st gear...revved up to around 6000 rpm's by the time I realized it and stopped on the side of the road. I put it in neutral and then back into drive and it was fine...not sure why that would happen?? Anyone else have this issue? Thanks in advance...
