3.0 Duramax Shudder?
bilge pump replied to thegrizz's topic in Engines & Drivetrain (V8, Duramax, TurboMax)
I had exactly what others have described with the shudder while accelerating. took several trips to the dealer (they were great. stuck with it) over about 9 months but seem to have gotten it fixed. Mine is a '22. service manager told me there was a TSB on '21 models to change the transmission valve train. replace the one in my truck and I haven't been able to recreate the vibration.
