So, the ECM flash helped for a bit, but the low speed transmission issues continue. Also, I noticed that if I take off from a dead stop I get two different responses based off of my acceleration. If I floor it, there is a momentary hesitation, but then it accelerates through the gears forcefully and (relatively) smoothly. If I'm only partially depressing the gas pedal, I get a whole bunch of gear seeking, jerkiness, hesitation, and just a plain crappy driving experience. I've also been noticing a lot more weird electric bugs start appearing, like my backup camera going out on occasion, and I have to stop, put it into park, then back into reverse for it to come back on, or yesterday morning when I had to hit the Unlock button on my fob seven times just to get the rear door to open (when it normally just takes two). I did go back to the dealer last week to have them look at the transmission, but without a CEL, and without any codes, they said the best they could do is keep it for a few days to see if they can reproduce what I am reporting. Of course, they had no service loaner trucks available at the moment, so that wasn't an option. I paid $54,100 OTD for a well-equipped Big Horn with a set of upgraded leather Katzkins, but after 3,700 miles, Carmax says its worth $40k. Previous two trucks were twin turbo V-6 Ecoboost F-150s that I put 100k miles on without a single issue, and I'm starting to think that trusting Stellantis was a bad move.
