Dealer wants to charge a $200 diagnostic fee for vehicle under warranty.
I’ve only found SSPD6 which addresses the rough shifting that’s only for a very small group of vehicles with a build date prior to 2024.
I can’t seem to find any other official service bulletin or campaign that addresses the 1st gear rough shifting issue for build dates 2024 later. All I’m finding loop is a generic callout for PCM and TCM recalibration.
dealer is saying there are no open technical service bulletins, or campaigns therefore, they would have to run the diagnostic.
