    People don’t realize that Spicer had 14/16/18, & 20 speed transmissions since the 60’s. The 18 speed that we know today didn’t evolve when Eaton /Fuller introduced it in the early 90’s. Trucking had always had those transmissions available. But the popular trannies with low hp hauling general freight only need a 7/8/9, or 10speed to do the job.

      In Europe we never had 18 speed gearboxes. 16 at last. I drove Volvo 12 speed gearboxes for years and years. Easy shifting and if you have a powerful engine like Volvo has with lots of torque you don.t need more gears. And now i drive the Volvo I shift,best gearbox in the world.

    The 18 speed that I had, gave me a200 rpm gear step. That permits you to keep the engine in the peak power range. That is very helpful when you are carrying a full load in the mountains. That was particularly helpful to me on Interstate 70 going into Denver, Colorado. You climb up to 10,500 feet,then back down and up to over 11,000 feet. When climbing these mountains with a full load, it is very helpful to be able to keep the engine in the peak power range.

    There is one other factor - and that is that far more freight is moved over a much greater distance now than back in the 50's through 80's, thanks to the development of the US Interstate Highway system (and Canada's own highway system). Prior to the 70's, a lot of freight was moved by train to a distribution warehouse where the trucks took it to the retailer. The distance the truck traveled was a lot shorter and the load was a lot lighter so a 5 speed transmission was more than enough. Now, however, trucks drive loads thousands of miles cross country, and they need as many gears as they can get in order to climb hills safely and keep the engine turning at the optimum RPM for performance and fuel economy.

      My dad was 16 when he started driving trucks for my grandad in the mid fifties in Colorado. He said all the trucks he drove back then had two gear shifts, one for the rear end and one for the transmission.
      A 5 speed is really a 10 speed with a two speed rear axle.
      The engines were weak but they had one truck with a Cummins or a Detroit Diesel that would pull hard. And with the introduction of turbos, the power only increased.
      50 mph speed limits were common then too while paved roads in the west were not.
      He said he regularly loaded hundred pounds sacks of beans into the trailer for hours before driving for days to his destination. He got buried one day when he fell asleep in the trailer loading up. The other guys loaded the beans around him.
      They used to load their trucks by hand before heading out. Those days are long over. They also didn't have HOS regulations and most drank beer while driving.
      He rolled a truck one day in the middle of BFE with his dad in the sleeper which killed him. He quit driving after that.

Some had a two speed Rear axel, the two speed was not the split type , but one that would only go 40 mph in low range and on the highway, they could go over 80. the loads were over 120.000 pounds, and they needed low gears to lift loads in tough conditions. A truck with a 10 speed would never have got off the landing. having lots of gears is in no way a new thing. i remember one Truck that had a 15 speed with a 4 speed Axillary..

      ​​@@288gto7 yep. Then in the 1950s there were many different variations of the automatic transmission ranging from no true gears (the Dynaflow transmission, used mainly in Buicks, indeed a very smooth but inefficient transmission as there was no feel of shifting and the driver could accelerate while maintaining a relatively steady engine RPM similar to the CVT used in many of today's sedans with inline 4 engines) to 4 gears. By the 1960s until about the mid 80s 3 speed automatics had become pretty much the standard across the board.
      The original 4 speed hydramatic design (1940-1956) was a complex design that was very heavy and expensive to manufacture. Today, Hydramatic remains as a trademark name for automatic transmissions produced by and used in GM vehicles even though they might bear any relation to the original hydramatic design.

    Trucks back as long ago as the twenties also had auxiliary transmissions along with the main transmission.. so you could have a main box with 5 gears and a second box with 3 or 4 both with separate shift levers and you also had 2 speed rear ends so you could in fact have had as many as 40 different gear ratios or more if the truck was equipped with the aforementioned set-up, which was not unheard of or even uncommon.

    I "grew up" in trucking with 13 , 10, and one 5x5 transmission. This allowed for a smaller difference between max torque and max horsepower, meaning keeping the engine in a range it was most efficient in. The people doing this video missed that part of it AMT transmissions are very sensitive to battery voltage. A reduction in voltage from the desired 13.8 to 14.5 will cause drivability problems, just as bad as a shift system getting extreme voltage, typically over 15, with actual component damage possible if the sensitive parts have a voltage over 18VDC . I have driven AMT transmissions and have asked shops to check the output voltage and the battery condition when drivability was suspect.

    I have no experience on driving and many other things, but i prefer always having FULL control over the situation and each tiny detail, so i would prefer manual transmission, maybe semi-automatic, but never fully automatic transmission, having an automated system take control over my movements would not be fun at all, not one bit.
    With manual and semi-automatic i would have full control of the transmission and i can know what it's doing at all times and act as i see best fit the situation.
    Though of course, an experienced driver would put the vehicle to better use, but manual transmission allows said experienced driver to actually do his job.

    Also, when you have an 18 speed you don't use all of the gears. Acceleration from a dead stop with a full load on flat ground you will probably start in fourth and be in high gear by 60mph. The huge number of gears is so you can start with a low range and optimize your hill gearings.

    There is a 1937 Life Magazine article where a writer follows truck drivers in new industry at the time, long haul trucking. In this article, a driver named Red, is driving a diesel Autocar big rig. It says right in the article that his truck had 18 forward gears. That was in 1937.
    In the same article it shows pictures of modern looking 18-wheelers going across the Arizona desert.
    Gasoline trucks at the time may have only had 4 or 5 gears, but because of the limited power range of diesels, they had to have a lot of gears.

    When i first started loading Log trucks Most trucks had a 5-speed main and a 4 speed Auxiliary that is 20 gears, Some even had 2 speed Axels then they went to a 13 or 15 speed now they have updated the 13 speeds into 18 speeds. I always thought 20 was more than 18.
    Some guys tried Automatic transmissions for logging but the lack of ability to lift heavy loads in muddy conditions soon eliminated the Automatic trans. i have seen Automatic Transmission trucks sit in the mud and moan when they were trying to lift a heavy load. The transmission is not the problem but the, Torque converter slipping under hard load is why Automatic trans are not the best. The old manual 5x4 trucks always had a gear low enough that they could lift the load. I have seen Trucks with a 250 hp lift a load were a 500 hp with auto would fail.

    Diesel engines have narrower torque band than gasoline engines, therefore they need more gears. But in real life scenarios, the most gears practical would be 9, 10 speed. Usually the more speeds go to drivers that been with the company for a while with proven abilities. Most drivers are not the best trained , and when you stick them with a truck with split axles and you have to shift a certain way through the gears, for at least the first day or so, you have to think before every gear shift and they often damage the transmission. Many do not even know to look for the shift pattern at the top of the visor or a sticker on the panel somewhere. This is especially true with agency drivers that never get the same truck twice. If the shift pattern is not available , you have to guess. Most people get out of driving schools using an automatic, and it is possible to get a truck license and you cannot shift gears , and even to get a job (cement trucks)

Volvo trucks come with automatics as 'standard', their dual-clutch i-shift automatics are light-years ahead of the old 18-speed manuals in every respect. However, other brands of automatics can be horrible by comparison.

They need to shift at least once and the timing had to be perfect. 1/4 second slow and the truck rapidly lose speed to a dead stop........on the slope. be rough on the drive train, and you are likely to drop a drive shaft. I say only the top 5% of drivers can do these jobs. Just like shunting, for the top 5%, they have one try time allowance to back a trailer in perfectly. Most drivers are not that good.
