No Manual Option When Building 2018?

You won't see that plowing snow because of the cold ambient temps.

In my 97 Chevy the transmission temps would get hotter plowing snow in the dead of winter than towing 6k on the highway in summer. Can't say what my Ram does because I don't have a trans temp gauge yet. Plowing is hard on a transmission, even if you nurse it along.

You are welcome to come up here next winter in January or February and ride with me when I plow an access road or two. I have a feeling that it would be an enlightening experience for you.

Hmmm. What is this snow they talk about? Or automatic transmissions? Don’t have use for either I reckon.

Imagine pulling a 36 ft trailer through muck at 90 -100 °F. Which could be the same load as plowing snow at 0° F. But at a much (100°F ) higher temp.

1st. What does any of that have to do with running with the converter unlocked? 2nd. Plowing. You really should stop pontificating about things of which you have absolutely no knowledge. All you do is confirm everyone’s suspicions.

The TC unlocks to shift gears. And that is what creates the most heat in a transmission.

When it hunts for the right gear as everyone describes who has an automatic, it heats up

Take the winter front off

Now take your loaded trailer and go from drive to reverse and back again a few hundred times a night. Then you will have a picture of the abuse a transmission takes in a typical plowing session.

Good point.

What temps do you reach? Or do you monitor those?

I've had to go back and forth to rock myself out of mud. Not pulling a trailer just deep in mud without a trailer.

It's not recommended to slam into gear with an automatic.

But it's pretty simple and quick to do with a g56 even with the notched reverse gear.

 

[jgillott]

220-230 sustained on an old 48re in our 04.5 is typical. You can cross 250 easily if not careful. It doesn't shift well at that temp.

.newsa newsa newsa. You do realize the two main gears you plow in (first and reverse) NEVER lock the convertor.

I'd offer to send you a shovel to dig yourself out of this one but shipping an excavator from Ohio to Florida is expensive

The poster you quoted never said anything about an auto trans hunting. Converters that lock in any gear other than high are relatively new. Before the 70s there were NO lockup converters. Transmissions didn’t regularly burn up. You’ve got a multitude of theories but NO actual experience or working knowledge. Your ignorance is showing. But then again ,it always does.

Before the 70's there weren't any automatics designed to pull more that about 3000-4000 lbs.

The point is, you've now made two comments relating to transmissions making heat with the converter unlocked. Yet fail to connect that with the abuse a transmission takes plowing snow. Ambient temps don't play as big a role as your making it out to be.

My experience with the temperatures of my differentials in 100°F weather vs. -15° F weather on the hwy driving all day unloaded.....there was a significant difference. Now I realize that the automatics are huge beasts and won't lose as much through ambient convection. And I also realize the transmission cooler cools through the engine coolant, so it is a different beast. But working a transmission hard on muddy/sandy roads (under load), and always needing to change speeds so it's always shifting will increase the temps quickly. And the difference between 230° F & 240° F is a pretty big difference in transmission wear (operating all day).

Now, I realize that my g56 is more like the differentials in the way it cools. Maybe I am mistaken about how well the automatics will perform when worked hard off hwy in rough conditions. But it seems that Andymacs g56's are not the weak spot. Sounds like the frames are his weak spot. My opinion is that the automatics like the hwy better.

 

[Newsa]

What I do like about the design of the automatics is that the engine coolant helps warm them up in the winter and helps cool them down in the summer. And the efficiency is slightly better with the automatics. But that can be partially offset by the weight depending on what type of driving the truck is used for. That's about all I like about the automatics

True the G56 has never been a source of problems for me. The biggest issue I have had is front ends and steering linkages. Every 25-40k miles without exception we replace that intermediate steering shaft and do a complete front end rebuild. At that point the truck is scary to drive on the freeway and handles like an abused Walmart shopping cart. Never replaced a G56. Clutches are rare. But front ends holy cow. Some people say Fords are better. Nope. Same nonsense in F350’s as the ram. Just Fords throw electrical issues into the mix.

Amen to that amigo.

Which has what to do with an unlocked converter overheating a transmission? Why don’t you just admit you don’t know a thing about auto transmissions and drop it. We’re not those poor children you’re supposed to be educating that are forced to take whatever you force upon them for Gospel.

The new age world has progressed regressed shifted (pun) to a point where the manual transmissions available, are unable to handle the input torque @ RPM in a package small enough to fit at a price point to make them viable, and still able to be shifted by humans who get less and less talented each fiscal birth year...

...at the same time automatic transmission "technology" is getting better. They are still full of magic voodoo to most people, even many professional mechanics, but less often are they coming apart for repairs in the average joe/jane applications.

These new trucks are, pretty much, double the hp and torque (or more) of the original ones. The little 6.7 ISB is putting out numbers some of the EatonFuller transmissions cannot handle at this point. Hence the detune...

If a buyer can drive a manual and enjoys it, they still have 660 'torques' at their disposal, which not but a decade ago scooted most everything along just dandy. I haven't researched it deeply but I'd reckon that 930 out of the HO engine is torque limited until a certain point, because after that "monster Aisin" is a little Spicer u-joint system feeding a light truck rear end. It's all a recipe for drivetrain disaster if one looks real close at it.

I'd take a manual trans truck personally, but I can drive one, so....
