How Does an Automatic Transmission Work?

An automatic transmission can seem like magic. Also known as auto or self-shifting, the automatic transmission doesn’t require you to shift gears manually in order for them to change. It happens as you drive. The automatic transmission uses a combination of fluid, mechanical, and electrical engineering. Here is an overview of how an automatic transmission works.

What is a transmission?

A transmission is what allows a car move into different gears. Without a transmission, your car would be stuck in one gear regardless of the speed and power required to move your vehicle. If you’re driving up a steep hill, your car’s needs are different from if you’re in rush-hour traffic in the city. Basically the automatic transmission helps your engine spin at an optimal rate for the driving conditions and all you have to do is press the brake or gas pedal.

Parts of the Automatic Transmission

Parts of the automatic transmission include: a torque converter, oil pump, band breaks, planetary gear set, clutch packs, valve body, output shaft, and hydraulic system.

The torque converter is what stops your car from moving when you turn on the engine. It connects and disconnects power from the engine and is found between the engine and the transmission. Once you put the transmission into drive and your car is moving, the rest is automatic.

The planetary gear set is the heart of the automatic transmission. It’s what allows you to reverse and achieve five levels of forward drive. This one set of gears produces all the gear ratios. The planetary gear set is made up of three components: the sun gear, the planet gear, and the ring gear.

The band breaks are responsible for gears in the planetary gear set to be tight or loose allowing them to spin at different speeds.

The valve body can be considered the brain of the automatic transmission. The different valve passages direct different pressures of transmission fluid to different areas. Depending on how much pressure you put on the gas pedal will determine where the transmission fluid goes in the valve body. The clutch pack is then activated and will smoothly shift the transmission into a different gear.

Transmission (or hydraulic) fluid acts as a coolant and lubricant within the transmission system and helps to prevent corrosion. It transmits power from the engine to the transmission. Its role is important in the automatic transmission.

How an Automatic Transmission Works

When you turn on your car, the engine is on, but the car doesn’t move. When you step on the gas, the torque converter pump spins faster, sending transmission fluid toward the turbine. This fluid force is what turns the wheels. The operation of automatic transmission is all about transmitting different rotation speeds into the ring and sun gears. By holding the planet carrier, sun, or ring steady, a different gear ratio is achieved.

As you can see, the automatic transmission involves a lot of parts and movements to work. As complicated as it all seems, it’s hard to deny that it’s an impressive system!

Summer Car Maintenance Checklist

Summer car maintenance might not seem important, but it’s just as important as the winter car maintenance you do to prepare for snow, ice, and rain. Summers are hot and dry and this can impact the running of your car and even your personal safety. Here is your summer car maintenance checklist.

Check Your Battery

The last thing you want during the summer heat is to be stranded somewhere because your battery died. You want your battery to be corrosion free. If you notice the battery and cables need to be cleaned, take the time to clean them. You also want to check your battery charge. If you need a new battery, don’t put it off and hope for the best. It’s better to spend the money on it now and avoid additional costs later if you do need a tow.

Test the Air Conditioner

Whether you’re staying close to home this summer or planning a road trip, you need to make sure the air conditioner in your car is working properly. Hot temperatures outside will heat up the interior of the car and make your summer drives uncomfortable. Make sure that all vents are working and blowing clear air. If they are dusty, you’ll want to clean them to prevent dust and dirt flying around the inside of your car.

Check Fluid Levels

Coolant is especially important during the summer. You radiator works extra hard during the warm summer months to keep your car from overheating, so make sure that’s topped off. Check to make sure levels of steering fluid, brake fluid, windshield wiper fluid, and motor oil are at optimal levels. Make sure you top off the fluids before you begin driving and that you use the right products for your car’s make and model.

Test the Tires and Brakes

In addition to brake fluid, you’ll want to check the condition of your brakes, brake pads, and hoses. If they need replacing, take care of this immediately. Depending on where you live, the harsh winters can be hard on the brakes, especially in areas that need to use a lot of salt on the roads because salt can corrode the breaks. You should also check your tires to make sure the tread isn’t too worn or that here isn’t a leak originating from corrosion on your rims. Checking tire pressure should be done on a regular basis also as temperature fluctuations can cause pressure loss. Incorrect pressure can lead to poor performance and reduced gas mileage.

Put Together an Emergency Kit

It’s hopeful to think nothing bad will ever happen, especially if you’ve done all of your summer car maintenance, but sadly this isn’t the case. Unexpected things can and do happen. Your car should always be equipped with items you might need in an emergency. This includes, but isn’t limited to: a first aid kit, bottled water, non-perishable foods, blankets, jumper cables, a spare tire, and a flashlight.

Preparing your car for summer is as important as preparing it for winter. Every season has a set of conditions that can impact your car. This list will have you prepared for driving in the summer!

BMW 3 Series Used Buyer’s Guide

2012 BMW 328i
​The compact entry-level 3 Series reigns as ​BMW’s #1 volume-leading bestseller and is the most popular model in the marque’s lineup. It was introduced in 1975 as the successor to the New Class 02 Series and has remained in regular production ever since. With a base price that competes with many other contemporary midsize family sedans such as the Toyota Camry, Honda Accord, and Ford Fusion, the 3 Series is arguably the most mainstream of all of BMW’s present-day crop. It’s far more than just a basic commuter car, though. The 3 Series, like its larger sibling, the elite ​7 Series high-end luxury saloon, epitomizes the BMW trademark amalgamation of style, luxury, and performance but unlike that premier flagship vehicle, the 3 Series is attainable and has attracted a broad array of new customers ranging from suburban families to urban millennials. What was once previously exclusive to only the more ​affluent of citizens is now one of the most commonly-seen vehicles on American roads today.

However, the widespread popularity of the BMW 3 Series also saddles it with one of the worst depreciation percentages on the market today: a painful 46.9%. That might not mean anything to someone who leases from a dealership every 3 years, but it really sucks for those who bought brand new from the showroom. But as the old saying goes: “One’s loss is another’s gain.” High depreciation for the 1st owner can be a bargain buy for the 2nd or 3rd in line.

Driver’s Cars for the Real World

The 2019 Chevrolet Corvette ZR1: one step closer to owning your own C7.R racecar.
On November 12th, General Motors broke the Internet with the official world premiere of the 2019 Chevrolet Corvette ZR1 at the Dubai Auto Show. This fourth iteration of the iconic ZR1 nameplate (since 1970 with the C3 3rd generation Corvette) builds upon the monstrous Z06 supercharged C7 Corvette; a track-focused driver’s car that features the latest and greatest sport performance technology General Motors has to offer. In their relentless efforts to compete against—and overtake—the world’s top elite high-performance Sports Cars, General Motors’ Corvette Racing Team has engineered this new ZR1 to not only unseat the previous ZR1 (last seen in 2013) as the fastest production Corvette in history, but to also become the world’s greatest Sports Car ever made. At the time of this writing, not much is known about the exact solid number performance specs of the 2019 ZR1, but it brandishes an all-new supercharged 6.2L Generation 5 small block V8 capable of churning out a hellacious 745 horsepower and 715 lb. ft. of torque VIA a new Eaton supercharger that is 52% larger than the one currently utilized by the Corvette Z06, Cadillac CTS-V, and Chevrolet Camaro ZL1. The 2019 Corvette ZR1 will also employ enhanced aero, cooling, handling and suspension modifications based on the Camaro ZL1 as well as a revised Z07 track option and a brand new ZTK performance pack that adds even greater handling capabilities on top of the already-impressive base setup.

The ultimate midlife crisis-mobile. More practical than plastic surgery, hairplugs, and ED treatment.
Pricing for the 2019 Chevrolet Corvette ZR1 is expected to start at $120,000. That’s quite a bit of coin, especially when the base Corvette Stingray—a powerful and capable performance car in its own right—begins at $55,000. That’s far less than what people spend for the typical full-size SUV. Of course, not everybody has an extra $120,000 in their back pockets or stuck underneath the couch cushions among the lost pens and long-forgotten, now-petrified Cheetos. However, when you consider the next comparable selections with this amount of power and these levels of performance capabilities, you’ve got to move all the way up to the Pagani Huayra, the Lamborghini Aventador SV, or the Ferrari F12berlinetta. If you have to ask how much these things cost, you definitely can’t afford them. That $120,000 price tag doesn’t sound so steep anymore, now does it?

Don’t want to spend $120,000? Check out these budget-friendly burners!

Review: 2018 Honda Civic Type R

After 2 decades, the 2018 Honda Civic Type R is FINALLY on American shores.
Well, boys and girls, it’s finally here. The new Honda Civic Type R, which was first revealed at the 2016 Paris Motor Show, has finally hit dealer showrooms and is on sale now in the U.S. of A. 2017 marks the 5th generation of the Type R variant of the Honda Civic and the 10th generation overall for the Civic, which has been in continuous production since 1972.

 

The 1973 Honda Civic epitomized the practical, affordable, environmentally-conscious, and budget-friendly economy car. Driving it was just as fun and engaging as walking or taking the bus.
A LITTLE HISTORY LESSON…

The original Honda Civic made its debut on July 11th, 1972 (as a 1973 model), replacing the N600 as the subcompact economy entry in Honda’s vehicle lineup. It was an immediate hit right out of the box in its native Japan, overtaking its domestic rivals from Nissan and Toyota. The Civic also achieved international success in both England and the United States as it specifically catered to motorists who were affected by the 1973 Oil Crisis and had grown jaded of the increasing banality of traditional, full-sized land barges. The Civic’s mass appeal as an inexpensive, fuel-friendly, and reliable (albeit, boring and uninspired) commuter car, combined with Honda’s growing reputation for hardiness, legions of Civic aficionados and Honda brand loyalists were formed as a result. In 1997, Honda’s famed Type R performance treatment was finally applied to the Civic, granting the little economy car to oin the legendary NSX supercar, DC2 and DC5 Integra, and CH/CL Accord in the Honda Type R stable of high-performance vehicles. The Honda Civic Type R remained unavailable in the North American market since its initial release but now, just in time for the first Civic Type R’s 20th anniversary, the newest iteration of the Civic Type R has finally made its way to American shores to do battle against other performance-oriented “hot hatches” such as the Volkswagen Golf R and the Ford Focus RS.
