The past few weeks I've noticed a real drop in power. Can't move away from a stop sign with any "punch". Then today hitched up the 5th wheel. Pulling up the mountain (in tow-haul) at 55 it would stay downshifted and would run at about 3000 rpm. Engine temp at 220 and tranny at 230-240 (factory guages. Backed off to 40-45 and ran at 2200 rpm, engine at 200 and tranny stayed at 240. Hit a turnout to let some folks pass (I know, they are not supposed to pass a Duramax!) and felt like I had to get out and push to pick up any speed from about 20-25 mph.
This is not the way it pulled up the mountain before! Any suggestions before I take it into the stealer.
