It definately didn’t feel like it went into neutral. It kept pulling and picked up a bit I just was concerned with how abrupt and fast the rpms shot threw the roof. Thanks for your reply. Does this change your view? I’m used to pulling with work trucks which are always been diesel so I didn’t know if the gas 2500 just runs like that?

Hi I recently bought a gas 2013 Sierra 2500hd. Low miles has towing package. Just today I bought a 4500lb dump trailer and was taking it home. I turned off tow/haul on the main flat roads but then came to a hill a few hundred yards long. I never put it back into tow mode and started climbing the hill and got to about 25mph but I wanted to see how the truck handled some more effort so I started accelerating but no response. Alittle more no response. At this point I have it a little more and the rpms suddenly jumped way up to about 5k at which point I let off. My question is this normal for the 6.0? Also should I be concerned at all about damage or wear to the transmission or engine from the sudden excessive jump in RPM uphill with trailer. Thanks
