Ha ha got it! Well let’s get to the bottom of this. What mileage you on? Have you done transmission service? I did a month ago. At 100k. Cleaned the EGR, took four a 50mile ride in 7th gear at 70mph to get the DPF cleared. I never had any dashboard warnings nor codes coming up on my obd2. Using shell V-Power 85% of the time. Shell helix professional oils... service done every 10k... and now she does me like that.
