2020 XLT with an Unleashed 93 tune, driven hard at times, but nothing crazy, no accidents, 34k miles, bought after my own lease.
Living in Michigan, have owned my truck for a few winters now and have experienced the clunky shifting in the early gears during colder months. I have had a 5 Star tune and as of about 8 months ago an Unleashed tune, so I have also experienced the difference between stock shifting and tuned shifting. As of about a month to two ago my transmission has been doing something compltely new and is missing(?) 2nd gear for the first 15 or so minutes of driving. When I shift into drive 1st gear opporates normally but when 2nd attempts to initiate the truck goes into a neutral state and revs with the throttle. The truck will eventually shift into 2nd gear after coasting roughly 0.5 to 2.5 seconds. I have learned to ease off the throttle as I anticiapte the truck is about to shift into 2nd and have found that to be beneficial in a more smooth shift when it finally engages into 2nd. Sometimes my residual throttle from accelerating through 1st will continue as the truck goes into neutral and the shift into 2nd will be slightly rough, but never anything that made me really worried.
As I mentioned earlier I have a tune on the truck and I have read through many threads on these forums about our transmission and the shifting, tunes and their impact on shifting, Misfitoy's transmission story, Torquerules tuning story. That being said I have tried removing the tune to stock, reset the adaptive learning, reset the keep alive memory, and tried reinstalling the tune to relearn shifting patterns. All of this with no measurable improvement. Am I missing anything related to the tuner to try?
I have let the truck warm up for quite some time before driving and also started driving immediately after starting it, finding similar results with possibly a slight improvement when it has been idling. The weirdest part about this to me is that the shift from 1st to 2nd will slowly improve back to completely normal after about 15 minutes. Once I feel it start to enage into 2nd more smoothly it only takes a couple more shifts, or maybe time (or temperature?), then it is opperating as if I never knew the problem existed. If I turn the engine off for a shorter amouint of time (have not tested this too much, but maybe up to an hour or so in the cold?) then turn it back on and start to drive, it will generally be just fine. All of this anecdotal information has led me to think temperature has something to do with it, but it just seems so extreme that it is quite worrisome.
