1. Automatic
   Non-Synchromesh
2. Longitudinal
   Synchromesh

Odds are if you're driving, you're using an automatic gearbox, a synchromesh gear box, or a non-synchromesh. The first is obviously automatic while the second two are manual. Non-synchromesh requires you to double-clutch to shift. There's no such thing as longitudinal, though.

1. Three-speed planetary
   Six-speed automatic
2. Dual clutch
   Continuously variable

Ford introduced the Model T back in 1908 with what it called a three-speed planetary gear transmission. Today, it gets a gear knocked out of the mix because one of those three is reverse and we wouldn't count that.

1. Latent
   Manual
2. Planetary gear
   Shiftless

Continuously variable transmission is also known as shiftless transmission and is a kind of automatic transmission that easily shifts through gear ratios. It uses a belt-driven design that's still less effective than automatic but makes up for it by being cheaper and better at allowing an engine to operate at its highest RPMs.

1. Around 0.1%
   Less than 4%
2. About 10%
   No one collects data on that anymore.

The market share for manual transmissions is under 4% in the US and it seems like few people are even aware of how to drive a manual transmission car anymore. That said, manual transmissions are generally cheaper to make and more fuel-efficient and better-performing than automatics.

1. Transmission control unit
   Transmission gear restraints
2. Drivetrain
   Flex gears

The TCU or transmission control unit adds more cost to an automatic transmission, as a manual doesn't require one. The TCU uses senses and data from the engine control unit to operate the transmission, which means it needs software and proper calibration as opposed to the simple mechanics of a manual transmission.

1. Ford F-100
   Chevy Blazer
2. Toyota Tacoma
   Dodge Ram SRT-10

Usually shortened to the T-56, the Borg-Warner T-56 transmission was first built for the Dodge Viper in 1992 and then found its way into the Dodge Ram among many other vehicles. Ram was one of the only trucks that used the transmission, but you could also find it in Corvettes, Camaros, Mustangs, Aston Martins and more.

1. Cruise-O-Matic
   Ford-O-Matic
2. Merc-O-Matic
   All of the above

Ford developed the Ford-O-Matic transmission at the end of the '40s for market in 1950. By 1958, the company had opted to call it the Cruise-O-Matic but it was essentially the same transmission. Of course, for Mercury models, the company went with the name Merc-O-Matic.

1. Chevy
   Mazda
2. BMW
   Leer

The M5OD transmission was made by Mazda and stood for Mazda 5-speed with Over Drive. It was a manual transmission available for light-duty and medium-duty vehicles. The 2011 Ford Ranger was the last truck to make use of it.

1. Tremec TR 6060
   AXOD-E
2. Allison 10-speed
   ZF Powerline

Chevy's newest trucks are outfitted with an Allison 10-speed transmission, which seems to be a response to RAM's increased torque. As a GM rep said, they may offer more torque "but that’s academic if you can’t put all of that torque to the ground."

1. Chevy Avalanche
   Ford Bronco
2. Toyota Tundra
   Jeep Cherokee

Automatic transmission makers keep adding more speeds to them. Four and six used to be the norm, but in 2014 Jeep Cherokee became the first to have a nine-speed, and you can find 10-speed all over the place today, including in Chevy and Ford trucks.

1. Camshaft
   Drivetrain
2. Clutch
   Gearbox

The clutch is what connects the transmission and the engine in a vehicle. In basic terms, the clutch works by connecting or disconnecting rotating shafts. One is for the engine and one for the wheels. The clutch controls the slippage between the always-spinning engine and the only-spinning-when-you-want-them-to wheels.

1. 10
   12
2. 18
   22

For the most part, the highest number of gears you'll ever see in a semi-truck is 18. Pickups often have 10 these days and not all semis need 18, but they can be helpful for when a truck is hauling a massive trailer that weighs tons and they're trying to go down or up a hill safely.

1. Worn-out clutch
   The collar colliding with the gear
2. Out of transmission fluid
   All of the above

Part of the reason manual transmission fell out of favor is that when people use them incorrectly, they produce a terrible noise and can be damaged more easily than automatics. Anything from a lack of transmission fluid to a worn clutch to the collar literally grinding the gears could cause those sounds.

1. Measures speed
   Measures transmission fluid
2. Measures distance
   Measures RPMs

The tachometer on your dashboard measures the revolution per minute, or RPMs, of the spinning crankshaft in your engine. The name comes from the Greek word "tachos" which means speeds. The tachometer is pretty key for knowing when to shift gears.

1. Teeth
   Magnets
2. Oil pressure
   Friction

Gears are wheels with teeth on them and have been made that way for centuries. When the collar slips over the gear, it holds in place by meshing teeth together to create a pretty firm and solid meshing of the two.

1. Japan
   Italy
2. China
   All of the above

Manual transmissions are still hugely popular in most other countries around the world, including places like Italy, China and Japan. Part of this is an economic factor as they're cheaper to buy and many countries don't have the same income to spend on cars, so a cheaper option is always better.

1. Planetary gear
   Manual
2. Dual clutch
   Variable

Planetary gear automatic transmission is generally fine in cars, but in a heavy truck it could spell disaster. If the clutch slips as a truck is heading downhill it will cause the truck to accelerate and that can, and has, lead to fatalities.

1. Alternator
   Clutch pedal
2. Gears
   Flywheel

No need for a clutch pedal in your truck if you're driving automatic. If you know manual, though, then you've experienced the third pedal alongside the gas and the brake that operates the clutch in the vehicle.

1. Any
   3000
2. 2000

Ideally, you want to downshift when the tachometer reads 1 or about 1,000 RPM. That's just going to be better on your transmission overall and better for your fuel economy. Once you're really good at driving stick you can feel when's a good time to shift more than by just reading the tachometer, though.

1. 5,000 miles
   20,000 miles
2. 40,000 miles
   60,000 miles

Don't take this as gospel and consult your truck's manual to know for sure but, in general, a clutch is good for at least 60,000 miles these days. That said, some only make it about half that distance and some are good for more. Your mileage may vary, literally.

1. Air filter
   Transmission fluid
2. Tires
   Oil

If it's time to change the cutch you may as well take care of the whole transmission. You could use some new transmission fluid and, while you're in there, take the time to clean up the flywheel as well so everything runs smoothly.

1. Coolant has leaked into it.
   It got old.
2. It overheated.
   Oil got into it.

Transmission fluid is often described as milky although, to be fair, it's still pink in color so it's more creamy than anything and will often look like Pepto Bismol or strawberry milk. That said, a coolant leak is the most likely culprit here.

1. Tachometer
   Gear shift
2. Clutch
   TCU

Your tachometer lists numbers from 0 up to 14 and then, beyond that, you'll have numbers up to 17 in red. Above 14 is your tachometer's redline where you're pushing your engine beyond its safe operating boundaries and are risking damage.

1. Vacamatic
   Presto-Matic
2. Merc-O-Matic
   Turbo-Hydromatic

GM designed the Turbo Hydromatic line of transmissions. It was the evolution of the Hydromatic which the company developed in the 1940s and had installed in nearly all of its vehicles throughout the 1950s.

1. 8L90
   Aisin BG6
2. MTX-75
   Alisin 10-speed

The Chevy Colorado has been rocking the 8-speed automatic GM 8L90 transmission since 2015. The same transmission can be found in the Camaro, the Cadillac CTS, the Yukon Denali and the Corvette Stingray.

1. 1st
   2nd
2. 3rd

The gears of your manual transmission go in order from 1 to whatever number you may be rocking. There's no secret to this one, the lowest gear has the lowest speed output, so if you're in no serious hurry stay in first gear.

1. Automatic
   They're equal.
2. Manual
   Neither

Because of how an automatic transmission works, with things like the transmission control unit assisting how it functions, it will never be able to provide as much power as a manual. In fact, a manual transmission can give you around 15% more power.

1. Slow down
   Shift gears
2. Stop
   All of the above

When you hit the redline, it means you're at a dangerously high level of engine RPMs. You could stop or slow down to solve that problem and, of course, shifting gears is also an option to reduce strain on the engine.

1. Yes
   No
2. Depends on your speed
   In cars not trucks

When you're in top gear and at top speed in your truck and you want to stop, you need to brake to slow down first, then apply the clutch, downshift and brake again, then apply the clutch until you stop.

1. Transmission control unit
   Flywheel
2. Torque converter
   Crankcase

In an automatic transmission vehicle, the torque converter is a fluid coupling that does a job similar to a clutch of allowing the engine to keep working while the gears spin independent of the engine until you're in a new gear.

1. Hold the clutch for a two-count.
   Hit the clutch, rev the engine, then clutch again and shift.
2. Accelerate and shift simultaneously.
   Brake and shift simultaneously.

Outside of racing, it's unlikely you'd ever need to double-clutch these days, but it was more common in the past. The idea is to hit the clutch to disengage the transmission, rev the engine to get the RPMs where they need to be, then hit the clutch a second time to shift.

1. The layout of the gears
   The arrangement of gear teeth
2. The proper way to engage the clutch
   How manufacturers align transmissions

Every gear shift has a pattern on it. Many of them resemble an H or a tree of some kinds. This shift pattern represents the layout of the gears in your transmission and operates like a map so you know how to shift.

1. Low gear
   High gear
2. Doesn't matter
   Depends on the vehicle

A higher gear is all about higher speeds, but it sacrifices torque, which is a rotational force. The torque is important in a truck if you're hauling something heavy or towing a large trailer behind it, so you won't need that high gear for a job like that.

The first manual transmission dates back to 1894 when it was invented by a pair of French inventors named Louis-Rene Panhard and Emile Levassor. The first automatic transmission was credited to Brazilian inventors in 1932.

1. Manual and automatic as one
   Both transmissions that you can switch between
2. A Ford trademark
   Automatic with a manual option

The name manumatic makes it sounds like it's manual and automatic transmission at the same time, but it's not exactly. It's automatic transmission with a limited option to override and shift manually.
