I have recently purchased 2005 GMC 3500 diesel 6.6. Drove the truck this morning everything was fine. When I left work truck shuddered between 50 and 60 mph when under acceleration transmission temp was 150 did the same thing last weekend under load and when not loaded. Problem goes away when transmission reaches 200 degrees any ideas of what this could be truck only has 97000 and 20 percent oil life left engine runs smooth at idle could this be a fuel filter issue.

Check the transfer case if 4x4. Pump rub through is a known issue causing the tcase to run dry. If it really goes away when trans gets 200f I'd look at getting it serviced. New spin on and dump then Fill with proper dex
Always good to do a new fuel filter and learn how to do the job yourself. 200 degrees for the trannie seems high. I don't remember 200 degrees towing our 35 ft alpenlite. If you don't know about the truck when towing use the tow mode everytime.
