Hey, I am having the same problem!!! Violent shaking in 8th gear around 11 to 12 thousand RPM, loss of power and bogging down. Have you figured out what your problem was. Also, the issues get worse when I am pulling a load.
Hey, have you figured out what your truck problem was? My 2012 D13 is having the same issues, violent shaking in 8th gear around 11 or 12 thousand RPM, bogging down, symptoms worse with a heavy load. No check engine light, nobody can figure this out. I am a new owner/operator and do not have a lot of money saved up right now!!!
