My father has a 2008 2500hd with the 6.0 4:10 gears no mods. He is hooked to a trailer everyday ranging from a ton to 4. It has good power for pullin but when a goes down hill it wont hold back trailer or no trailer. he tried the tow/haul on and even when he puts it in 1st it still takes off. took it to dealer they said thats gm fuel economy. dealer said there is a after market programer/chip that will help defuel it for hold back and wont hurt performance. Any ideas

"My truck has no engine braking. The dealer told me to piss off. What should I do?"

Trailer brakes....?

The new cummins come with factory jake brakes...

the dealer said they called gm and that it will feed a certain amount of gas all the time hense when going down a hill it takes off no matter what gear its in. they said thats how they get the fuel economy advertised. dont make sense to me, but gm not the dealer said there is aftermarket programer that will shut the fuel down to check at a offroad store

have trailer brakes but in the hills of western md 7 to 8% you will go through brakes pretty quick. have the same truck only a 06 and pulling same load i dont use the brakes near as much

Move the gear selector to a lower gear and/or USE YOUR BRAKES

not practical. tow 10k+ lbs in the mountains on 2-3 mile 8%+ grades and you will thank yourself for having working compression braking. been there, done that, it would hold the load at 50-55 mph the whole time. why kill your brakes and heat them to the point where they fade if not necessary?

That's why i wish Gm would have put the allison trans in the 6.0 trucks. It really helps hold the truck back when going downhill. But it only comes in the duramax. I don't know how hard it would be to swap trannies but it has been something i have been considering.
