I have already heard back from Trifecta and they sent me another tune file as they said my car did have a factory update available to firm up the shifts. I will install it and test it for a few days and post the results.Thanks for contacting us John. I was about to reply to your comments here, or in another thread that there have actually been some factory updates to solve some of these transmission shift quality issues, we can check to see if your vehicle is affected and offer an update.
I've got an engineer assigned and looking into your ticket as we speak. Please allow 2-4 business days for a reply with an update to the ticket.
Great customer service on the part of Trifecta, I only wish I contacted them a few months ago when I bought the tune, my mistake.
