'14 6 speed manual EB question

[TRAMPLINEMAN]

How do you activate the exhaust brake?

 

[MelvinPierce]

Push the EB button on the dash. One push, full brake, second push, takes it to auto brake. Third time takes it off.

If you have in tow mode, it is more aggressive. If you are braking and in tow mode, even more so, plus stays on to a lower mph.

Thank you. I wasn't quite sure as to which button was for the EB. The symbol on my dash for the EB is the same symbol in my work truck for manual regen.

That seems weird. You got if figured out then. Good.

There is no tow haul mode for a manual 6 speed transmission. I have a 2013. Love the EB.

I do have a question to add here though while we are on the topic of g56 6 speed manual transmission.

I read somewhere on this forum that when you have automatic transmission,
It's not good to floor the accelerator while the engine is cold.

But with a manual transmission, it seems it won't hurt it as long as the engine speed is not turning to fast?
I think the rationale with not flooring the automatic is because of the higher engine speeds when flooring it cold.

Mine seems to warm up faster if I dump the throttle while its under load as lomg as I keep the engine speed between 1300 & 2200 rpm.

Seems to me like the manual transmission gives the driver more control over warm up conditions.

Since I only drive 6 miles to work and it is a daily driver, it is just reaching 190 F when I reach my destination.

Also.wondering if tow mode is activated for the engine in a manual g56 6 speed when you plug in the trailer wiring harness?

I think it is. It pulled beautifully through the mountains last June.

I think it adjusts injection timing? There is no tow/haul button on the 2500 with g56

Thoughts: The manual engine is down rated in horsepower and torque compared to the automatic. The automatic trucks have programming that limits the amount of torque and horsepower that can be applied in certain operating conditions, thereby allowing an increase in total available "controlled" power. The automatic trucks have programming that allow tuned operation for towing or hauling a heavy load. The manual truck has a driver who is responsible for all of the above. Newsa, I think you need to keep your batteries charged! <G> You're in charge of your truck's operation, with very little computer oversight.

 

[Newsa]

Doubleclutch you are correct. Although the manual is downrated/detuned in peak HP, I imagine when the transmission temps in an automatic reach a certain temp, that the automatic 68fe & Aisin programming also tells the engine to produce less torque & HP.

I am sure that the 800 & 850 ft lbs of torque are mostly just used as a sales mantra.

Most of the time the engine is programming itself into a significantly lower torque HP
scheme.

Newsa I'd avoid full throttle operation before the machinery has warmed up. Warm up is to get moving and stationary parts expanded to the right tolerances, and the oil operating at the right pressure and viscosity. Max throttle means max internal loadings, so I'd be inclined to be gentler before it's warm. We're only talking differences at the margin here, as to whether your truck lasts for a very long time or a very very long time, but every little helps.

The manual says: "Avoid full throttle operation when the engine is cold.When starting a cold engine, bring the engine up to operating speed slowly to allow the oil pressure to stabilize as the engine warms up."

It also says: "Operating the exhaust brake at idle will greatly improve warm up rate ...", so that might be a better way to speed up warm-up.

Sorry Newsa...

Nope! The new automatic trannys are significantly beefed up compared to your "hand shaker" with flywheel/clutch. This is my first auto, and I've been pulled out from under the rock I've been happy living under for many years. Technology has embraced the use of computers to monitor and adjust operating conditions that allow more butt to be applied to the rear wheels than could be done so in the past. My old 5 speed and (cast iron) 6 speeds are warm fuzzy memories of the past, when the automatic transmissions were limiting engine horsepower/torque. We ask for more power/torque, and have to make adjustments on how we handle the package given us. Your manual transmission, flywheel, and clutch limit the output of your engine in the number game. It's just a number. Next year, it will be another number, and it will be bigger, but it will be and automatic transmission number. It's a given. Enjoy what you have, and don't get sucked into that dipsy-doodle number game. When was the last time your foot was to the floor and you had to ask for "more power, Scotty"?
