Towing with a Manual

I think you are aware of how to launch and drive the truck trailer combo, just ask your friend to let you know if you are not driving his truck the way he likes. I think most of us are a little protective of our trucks and it is hard to be a passenger when someone else is driving. That is probably why he bought a stick. He wants and likes the feel. The better you mimic that feel he likes will make the trip even smoother. You sound like you are a good friend, enjoy the trip.

Thanks for all of the info guys, I really appreciate it. I wasn't aware of the zero throttle launch system,and it sounds like a great system. I'm heading over to Edmonton tomorrow, and I'll give a quick rundown on how the trip went after I get back. Thanks again!

Its a dream machine for towing heavy trailers however not everyone can use a manual and make glass smooth up and down shifts. After a while you can make those smooth shifts.

The Cummins from '03 and up uses the zero throttle launch system. Simply let the clutch (keep your foot off the go pedel) out and the Cummins rpms comes up which eliminates stalling on any grade. With the deep 1st and 2nd gear there is no need to slip the clutch....ever.
If its flat I take off in 2nd gear empty of pulling. When empty I go with 2nd....4th ....then 6th. Pulling a load I run the gears.

I believe that that is true from 99.5 on up, once the IP was electronically controlled.

The best part of that feature is when you're crawling along slow dirt roads. You can select any of the first 3 gears and, when empty, the truck will maintain idle speed even uphill with no throttle input. Dooing it with a load on causes the engine to surge and then back off too much in 3rd though.

We bought the trailer in my signature last year in Edmonton and towed it back to the coast with the truck in my signature and it towed like a dream (my truck also has the G56 manual transmission). We have since towed the trailer (which weighs 16,000 lbs) on countless trips and the truck handles it extremely well. As others have said, the Cummins has a zero launch feature so you can let out the clutch with the transmission in first gear with no throttle. The truck will take off like nothing is even hooked to it. You can start the truck off in second gear with no trailer connected. As others have said, don't lug the engine (the Cummins will tow that trailer in 6th gear at 1500 RPM or less for most of the trip), and there really is no reason to bring it above 2500-2700 RPM. When you do reach a large hill that will require a downshift, downshift it a gear fairly early to keep it around 2000-2500 RPM and it will march up the hill easily.

Ensure that the exhaust brake is on FULL setting (one push of the button on the centre portion of the dash and the icon in the instrument panel will light up yellow). If the icon is green then the exhaust brake is on AUTO setting which is not as good for towing. I usually descend moderate hills with my truck and trailer in 5th gear and steeper mountain passes in 4th gear and rarely have to use the service brakes.

You will be surprised how well the truck handles that trailer and the trip will go quickly! Drive safely in the summer traffic.

That's where that G56 shines is towing.
Use 1st to take off. Little burp on the throttle as you let the clutch out.
Make your up shifts around 2500rpms in general so you aren't lugging the next gear with that big trailer and enjoy the ride. It's a dream to tow with.

low rpms to start out.. most can do it AT idle.. till you try once.

little to No slippage of the clutch... match RPM to road speed per gear.

You will be fine. We all have learned.. and before 1960 all Towing trucks were manual.

The only manual truck I've driven was an 89 F-250.
To help the original poster, and for my benefit, is the first gear a granny gear? Basically only used to get a load started, otherwise you start the truck in 2nd gear? Also, is the first gear synchronized? I know it wasn't in my 89 (That or the synchros were gone by the time the truck was handed to me).

I would suggest going out for a drive with the truck before you tow with it.. Get a feel for it. Not Rocket Science! Have a good trip!! Nice truck Nice trailer, should make for a nice trip!! Good luck!!
