Automatic VS Manual Transmission

[frischtr]

I am surprised that Dodge has not canned the manual like Ford did years ago and GM did with a few years back.

Ford only quit with the manual in 2011, GM in '07... Needless to say, there were/are a lot of unhappy people on the enthusiast forums. Obviously the autos are far more popular, but there are still plenty of guys that want manuals.

"Good drivers" were hard to find in our delivery operation, many were temps or short termers who didn't give a bleep about taking care of equipment.

I think this is a pay issue, plain and simple. If a company can pay for good, hard-working employees, they won't have a hard time hiring and keeping them. It wasn't that long ago that a guy could support his family driving a truck, without his wife having to work, and be home most weekends. Ain't like that anymore...

Allison automatic transmissions seem to get rave reviews. What sets them apart from the others?

GM made a smart move, and for many years, had a hugely superior transmission to the other light truck makers. The Allison is hard to tear up and with the computerization, it is almost impossible to tear up.

Now if you also realize that GM's various 4L60 and 4L80 automatic transmissions through the 90s were pretty UNreliable, they really benefit from improving so much from where they were just a few years prior, to when they introduced the Allison transmission.

It seems that there are plenty of advantages to automatic transmissions when the driver is incompitent, lazy or careless. I am having a hard time understanding other advantages.

I am planning to swap the engine and trans in my 1977 ford pickup. My first choice would be a cummis with a 6 speed. Automatics are a lot easier to find. Should I comprimize? In all my years of driving and towing, I can not think of a single time that I wished I had an automatic. Well, there was the time I plulled my left LCL skiing, but none other than that. Have autimatics improved so much that manufacturers see no need for manual transmissions any more? Or is the recent shift (pun intended) toward automatics just due to consumer demand rather than technological improvement?

Not sure that it is the Allison trans itself as much as it is the (presumably "adaptive") algorithms in the smart box (-:

It just seems to do all the right things at the right times, e.g. put it in tow/haul mode on the highway at 65 and nothing much happens.
When you back off for the off ramp it will shift down at just the right speed, then shift down again - all just about how a better than me driver would do it on a manual if they were driving a manual, but SMOOTH and yet not slushy. I am fairly sure that it adjusts to load as well.

The engine braking doesn't always please me though.
There are times when I will dab the brakes just slightly to avoid an increase in speed on a downgrade, it senses that there wasn't enough deceleration and shifts down. If I do that again it will shift down again. It can become a real pain on long gentle down grades because it won't shift up again until I have been on the GO pedal for 1/2 second plus.
It isn't that I ride the brakes, it is that I should be able to use the brakes to avoid speed build up, not just to reduce speed.
It doesn't seem to "understand" that (-:

That's what happens when a company builds trucks the customers want instead of what the bean counters want. We get manual transmissions, you get a "man step" and lighted vanity mirrors.

That's because they both used the same exact ZF S6-650 manual transmission.

It's really quite simple. The bean counters won. The company gets dramatically more profit for the automatic than for the manual. Plus, the supply chain is simplified as is the assembly operations.

Well, OK, but the manual stresses the drivetrain and the engine more with lugging or dropping the clutch. I can't help but think the manufacturers are trying to give their overstressed engines the best chance to survive. Especially Ford and Chevy.

The autos are a lot more popular too. When I bought my new Cummins in 2004 there was a huge charge for the auto over the stick. No way that trans should have cost so much more. Seems like they just charge more for what's popular.

If you use cruise control it should pretty much do the right thing.

I am aware they used the same manual trans. I actually prefer that one to the NV5600 in my Dodge, but not much difference. If my 5600 ever does kick the bucket, I'll be replacing it with and Eaton-Fuller medium duty transmission.
