Are We Done Adding Gears to Transmissions?



Ford and GM raised the bar.

Honda's threatening to push it higher, but we might be approaching peak gearbox.

Here's why.

Let's have some FUN news!

original



S E E D E D   C O N T E N T



512 Plot a graph of the average number of gear ratios offered across the market by year and you'll end up with a gently rising slope that suddenly hooks skyward. The Ford Model T had two, and it took decades for transmissions with three or four gears to see widespread use.

But in the early part of the 21st century, we've seen the average shoot up as six-, seven-, and then eight-speed autos became commonplace. More recently, Ford and GM raised the bar to 10 with their jointly developed longitudinal box.

These modern gearboxes are complex pieces of engineering that allow substantial efficiency gains, especially when paired with turbo­charged engines with plentiful low-end torque.

Yet despite Honda's patent for an 11-speed triple-clutch automatic transmission, we are quickly approaching peak gearbox. That's because increasing the number of speeds also increases friction and rotating mass to the point of diminishing returns, but it's also because of the growing prevalence of hybrid systems.

Electric motors can add torque to the parts of the rev range where a combustion engine might leave drivers wanting, quickening responses and covering the perceived gaps in a vehicle's gearing.

"You simply won't need as many ratios to do the same job," Andy Palmer, former head of Aston Martin and a former transmission engineer, told us recently. "Plus, if you carry on adding ratios, you get to the point where you might as well just make a CVT."

And nobody wants that.

The Driving School Studebaker I learned on, and my first car (1950 Ford Custom Coach) had 3 forward speed manual gearshift (using a clutch, of course) with a steering column mounted lever  After that, every car I ever owned was automatic.  Only an enthusiast would want to shift through the greatly increased number ratios that have increased subsequently.  However, once you've learned how to drive a manual gearshift car, you never forget.

My wife drove only manuals from twenty years old to about forty. I suggested an automatic, when a new car was due.

We had taken delivery before she tried it out. 

She has never driven a manual since.

In regard to the CVT... you're absolutely right! Ford Motor Co. learned that the hard way with the CVT in the Fiestas and Focuses. I'm one of those weirdos that prefer a manual trans anyhow.

I had to order my 2012 Fiesta, because no manuals were available in the US when I was looking to buy. I get A-plan; so, it was a logical choice when a used vehicle would've cost me more per month and possibly more overall after APR was added to the cost of the vehicle. Now, I don't believe any US automaker is building vehicles for the US market with a manual in any vehicle line. I could be wrong though; I haven't looked in a while, but the last I heard is that US auto makers were getting rid of most "econoboxes" which in most instances were the only ones available in a manual that was NOT a sports car. 

I already warned my union-centric family [dad and father in law retired from Ford, stepdad retired from US Steel, uncle works for FCA, etc.] that my next vehicle will either be a much older model or if newer, it will likely be a Subaru Cross Trek or a Mini Cooper. I don't want to give up my manual trans!!! 

Last year, 5th gear went kaput on my way to work and I called 7 transmission shops in my area before I found one that actually still rebuilt manual transmissions. I was pleasantly surprised at the cost for rebuild; I assumed it would be $2000 especially considering it was the only place within 15 miles, but it was $1400.

Personally, I've never understood the way some people adore manual trannies. Automatics have been faster-shifting for decades, and as their shift-point management has gotten more sophisticated, they've now become more economical, too.

But... ... I know quite a few people like you, who want that manual... end of story! No argument allowed...

I suppose that's why the manufacturers produce a zillion different models every year: we each wan exactly what we want!

Me... I want quiet and comfortable. I don't care how many ratios... or even if it's continuous (as long as it doesn't buzz...)

That CVT is what caused Ford Motor Co. to recall hundreds of thousands of cars, buy backs, lawsuits, and many loyal customers were lost.

For me personally, I prefer a manual trans because of my sleep disorder. If I fall asleep at a red light driving a manual, I simply stall if my feet come off those pedals; if I fall asleep at a red light in an automatic the car moves if my feet come up off that brake pedal. Having a manual trans keeps me engaged in driving while on the road too; therefore, keeping me awake.

A manual always shifts right when you want it to and never shifts when you don't want it to. Besides they're a lot more fun to drive, a manual tranny makes any car feel sportier. I would love to be able to buy a modern sportscar with no power steering, no power brakes, and manual tranny, because that would provide the most feedback and best mental connection to the road, you feel everything. It's like the difference between walking barefoot and wearing shoes. Power steering can be quite good these days with a lot of feedback and tight and precise but power brakes still feel vague compared to manual brakes. Most people these days have never even driven a car with manual brakes, they're so used to that mushy brake pedal they probably have no idea what brake feedback would feel like. If you're wondering what modern manual brakes would feel like just ride a motorcycle. with power brakes you usually hear that you rotors are bad and they're really bad by that point but with manual brakes you feel it as soon as they get even a little bit pitted or rough.

My 1984 Ford Ranger had manual brakes, all 4 were drums and I only weighed 100 lbs. Panic stops were nearly impossible; I say nearly, because I had to panic stop ONCE when a semi truck decided he needed on the freeway and cut across 2 lanes to get to the onramp. I was in that far lane and he didn't care who was there.

My 68 VW Bus had manual four wheel drum brakes and they were very good. The trick with four wheel drum brakes is they must be in perfect adjustment and they should be checked and readjusted if the pedal goes down more than factory spec. most rear drums have automatic adjusters but most four wheel drum cars or trucks need to be manually adjusted. It is a fact that manual brakes require a little more muscle but if it's a good design and is working properly they should work very well. Manual brakes and especially four wheel drums just need more maintenance.

Considering I've been a mechanic on and off for many years, I'm aware. The pedal on my 84 Ranger didn't travel further than it should, but that extra muscle includes some ass behind it too and back then, I was tiny.

I'd like to teach my son to drive one, but nobody in my family owns a manual anymore.  Even my brother, who operates heavy equipment and use to drive a tractor-trailer, has a truck with an automatic transmission.  He messed up his shoulder wrestling in high school, and an automatic is just easier for him.

Probably.  I know he liked a standard, but his shoulder isn't getting any better with age, and shifting gears was painful.

I like a standard, but it's getting harder to find one to buy anymore.  Last time I was car shopping, there was no version of the car I wanted on the lot that had a stick shift.

Maybe... a lot of the "new" thieves are tech savvy, but not mechanically savvy. When there's not much reason to learn to drive a manual, why would they? If US auto manufacturers are doing away with all manual transmissions, there would be no reason for a thief to learn to drive one; not unless they're trying to steal classic cars / trucks.

You've never lived till you've down shifted going into a curve and up shifted coming out. I learned to drive manual the easy way, when I was young I rode dirt bikes so when I drove my first standard car at age 12 on my grandfather's farm it was completely natural it was the automatics that felt weird.

Until it blows out and needs replacing an example of this is the Saturn Vue, the cylinder has the drive go through it instead of the cylinder off to the side, to replace it you had to drop the transmission.  I could drive the vehicle without the clutch but my wife couldn't, so had to replace it.

Nah.. In Detroit... I will let it roll back a bit to scare the crap out of the person behind me. jrSmiley_68_smiley_image.png

My Fiesta has a feature that when on a hill, it will automatically keep the brake on momentarily when you let off the brake pedal, giving one enough time to move forward without rolling back.

When on a hill (and I mean pretty steep) in my '69 Nova, if someone was close behind me, I would set the parking brake just enough to hold me, release the clutch s l o w l y until it was engaged enough to prevent any rolling back and release the brake right at the right time and away I would go. Yep it probably wasn't the best for clutch life but I would rather have put a new clutch/pressure plate combo than have to pay for damage to the car behind and my insurance rates getting jacked up

And actually as time went on and I started drag racing it (IHRA street stock J) I got pretty good at holding the brake and accelerator with my right foot prior to green. (I had to do something as when staged, the car would roll slightly and I didn't want the staging light to go out if I drifted)

I learned to drive a stick in Morgantown, WV.  The joke about how steep the hills were there was that you could tell freshmen from upperclassmen by the size of their calves.  But yeah, I still hated it when somebody was behind me on a hill.

TBH, I haven't driven a standard in years.  Only once or twice since I sold my Subaru Outback with a stick shift to my ex.  But I like them better in the mountains or on icy roads - easier to control speed and torque.
