2012 RT SE5, was dying at stop lights frequently, I put in some Seafoam, it does it less often, but a new problem has popped up. If I'm cruising along in 5th gear and come to abrupt stop it only shifts down to second. If I'm going slowly in 2nd or 3rd and stop or slow way down it shifts down to first. I notice that when stopping aggressively from 5th when it gets down to 2nd it feels like and watching the tach it looks like it's going to stall, drops down to 600 rpm and then catches itself, but won't shift into first. If i give it some gas and then roll off the throttle it'll shift into first.
Ant ideas?
