Bought by Tremor in Sep. Just hit 3k miles. Unfortunately I've had some hard downshifting resulting in what I call a clunk or bang from 5th to 4th or 5th to 3rd on a regular basis only when the truck is warm. Didn't get much support from the dealer yet... Made appt, took it in and they tell me they are backed up 4 weeks and have to leave the truck on their lot in order to look at it. For my truck, it wasn't throwing codes or anything and the service manager took a quick ride and heard one of the softer clunks on the downshift but shrugged it off as this being normal for these transmissions.
Ultimately just had them log the issue as I couldn't leave the truck for 4 weeks... Don't get me started. Ironically put about 400 miles on it since I picked it up and it only has done it 1x where it was doing it 5-10x a week prior. Anyone else have shifting issues?
