anyone have a link to the TSB...I took my truck to the dealer a month ago and told them about this. They said they couldn't feel it and told me I had to go for a test drive with them to show them, but I dont have time. Mine occurs in 6th gear at 80 km/hr and or around 1500 RPM.
I will be getting this check out again and put my quad in the back when I take it there cause it does get worse with a load.
