    Ok I have to take my 07 classic 2500HD CrewCab 6.0 Auto trans truck pulling an enclosed 16 x 7 trailer from Indiana to Las Vegas. It will be empty going out and weight will be around 6500-7000 on the return trip. What are you suggestions for going over the big hills. Can I tow all the way in OD or Do I need to stay in 3rd.

    The reason I ask is the last trip I made out was with a 24 enclosed car trailer with a 70 AMX and lost the trans in Denver. I don't want to cook it again. The truck will be going straight thru only stopping for gas.

    The new trans has about 25,000 miles on it now. What do you guys suggest??

    Running out empty should be no problem even in OD except for the biggest hills. If it feels like it's struggling some on the very big hills go ahead and pull it out of OD ahead of time or if it doesn't down shift on it's own soon enough for conditions. Shouldn't need T/H when running empty but feel free to try it as well as it certainly won't hurt anything except possibly a little fuel mileage.The stock trans cooler should be more than capable of keeping the trans heat at bay for unloaded running conditions. Also be a good idea to check the cooler before your trip for any debris buildup such as leaves and bugs while it's on your mind too. It's easy to pop the grill out and clean it's fins with a nylon bristle brush and some good degreaser. Which is a wise idea on any truck every so often.

    Coming back loaded you want to only use OD on perfectly flat ground and also when speeds are below 55 mph or so, or in any kind of continuously up and down hilly terrain where the trans may shift too often. Use T/H on all the way back also. Doing so will help keep the converter locked more often and longer thus reducing heat production in the trans as much as possible. And most importantly, keep an eye on the trans temps. If it gets up around 220*-ish begin to back off it a little and/or drop to the next lower gear.

    Trust the gauge and monitor it periodically, thats what it's there for and will help you keep the trans temp in check.

    Sorry, I haven't updated. I have not left for this trip yet. I will be leaving Sunday evening. I have made this trip before, and lost the trans, that why I was asking.

    Our trannys are junk. Mine's been a POS since about 20k miles. Had a replacement and have the same problem, doesn't mean I didn't just order a new chevy. lol

    I saw OD the whole trip.

    BB-Need input

    Ok I made it to Las Vegas from northwest Indiana and This truck is really pissing me off.
    I averaged 7.9 MPG pulling a 7 x 16 enclosed trailer(empty). It is very difficult to maintain a speed limit pulling. The truck just feels like it has no power. It drops 20 MPH even on a small hill. It just does not want to go. I think there has to be something wrong with the computer control or something????? Don't get me wrong it runs out OK just No power up ANY king of hill. I was getting passed by mini truck with bigger trailers. I could not even maintain pace with a 1/2 dodge with a 24' enclosed car trailer with a car in it.

    What is up with that?????

    That Gas mileage is about what I get towing an 8000 pound 5th wheel, not an empty trailer. But holding speed you should be able to kick it down a gear and maintain. Sounds odd for an empty trailer. Was there a headwind?

    The 6.0 equipped '07's classics are extremely neutered so it's no surprise you're not happy with it on the hills. Keep your eyes open for a PM from me, I'll show you how to fix it not only to gain a rather substantial power increase but an MPG or two also. :salute:

    Ok, Thanks B&B, I be waiting. Now I am headed to the Palms Casino.........

    I have made this trip before with a 24' enclosed car trailer and got over 8 mpgs way overloaded, then 7.3mpg with a mid size car in the trailer. It has gotten progressively worse each time???????

    I have 3 2500 hd's but have duramax's in them, don't have any problems, but i never use the OD when pulling a trailer, and also always use the tow mode on the end of the shifter when towing, also by using it it helps saving on the trucks brakes by down shifting while stopping. The overdrive should never be used when driving at low speeds, it will keep shifting up and down and there fore go out faster, We pull 10,000 lb skid steers with the pickups with out any trans problems.

    Go back through these few past threads I dug up and most of your answers should be there Sid. If there's anything else more specific or something that isn't clear feel free to PM me once you have your PC up.

    Well I made it back to Indiana from Las Vegas and got 7.5 MPG loaded. I must clarify a little. Going out I had 4 adults and an empty trailer and pushed at around 75 MPH. Coming home I took it a little easier with two adults and loaded heavy, truck, trailer, and back seat. We took the southern route home as there is a lot less mountains to deal with. All in all the trip went well. The truck did OK but not great.
