6 Must-Know Facts About Automatic Transmissions

6 Must-Know Facts About Automatic Transmissions

Vehicles are complicated. Modern vehicles even moreso. It seems that ease of driving correlates with the complexity of how the machinery actually functions. Automatic transmissions are easier to drive than manual transmissions, because the transmission does more of the work for you. But just how they work can be quite confusing. If you would like to know a little more about what you’re driving every day, here are six basic facts about automatic transmissions.

1. Automatic Transmissions Are Different From Manual Transmissions

This one is kind of obvious, but there are significant differences between automatic and manual transmissions. Automatic transmissions are called such because they automatically change gear ratios as the vehicle moves. This frees the driver from having to shift gears manually. Like manual transmissions, the automatic transmission allows the engine to provide a range of speed and torque outputs that make vehicular travel possible. Another key difference between manual and automatic transmissions is that manual transmissions sometimes use transmission oil but automatic transmissions always use. . .

2. Automatic Transmissions Use Automatic Transmission Fluid

Automatic transmission fluid. It’s what keeps your automatic transmission running. It keeps it lubricated and helps to cool everything down.

3. Synthetic Transmission Fluid Is Usually Best

Check your vehicle’s manual to see which type of automatic transmission fluid your manufacturer recommends for your vehicle. Automatic transmissions often perform best when you use synthetic transmission fluid.

4. Check Your Automatic Transmission Fluid Regularly

Because your automatic transmission fluid is so integral to your vehicle’s performance, you should check it regularly. It’s a good idea to check your fluid every 16,000 kilometers or even every month just to make sure your levels are right and that the fluid is in good condition. If your transmission fluid looks opaque and/or smells bad, this is a sign that something is wrong. Bring your vehicle to a transmission shop.

5. Heat = Bad

Things tend to get hot under the hood of your vehicle. That’s unavoidable. But you have to be careful. Excess heat can do your transmission a world of damage. And it’s not hard to tip over that line from acceptable heat to dangerous temperatures. As many as 90% of all transmission failures can be caused by excess heat. Reducing heat means extending the lifespan of your vehicle. The best way to do this might be by installing an auxiliary cooler. This is especially a good idea if you use your vehicle for towing. An auxiliary cooler can reduce temperatures from 30% to 50%.

6. There Are Numerous Symptoms Of An Automatic Transmission Problem

Not sure if you have a problem with your automatic transmission? There are some telltale problems. You might have an automatic transmission problem if you experience any of the following:

  • Odd noises including whirring, humming, and clunking
  • If your transmission slips out of gear, typically by dropping into neutral right after you switched into drive or reverse
  • If your transmission offers resistance when you try to change gears and it grinds
  • Sudden changes in your Revolutions Per Minute (RPM)
  • Sluggish acceleration

Do You Need to Change Transmission Oil?

Do You Need to Change Transmission Oil?

We tend to hear quite a bit about transmission fluid. And rightfully so; transmission fluid is the lifeblood of your transmission. Your automatic transmission, that is. Manual transmissions are a bit different. Manual transmission fluid is most commonly called “transmission oil”, but different types of manual transmissions require different types of lubricants. Ultimately, the question is, if you drive a vehicle with a manual transmission, do you have to change the oil inside? If so, how often?

Manual transmissions

Most motorists understand that there are two types of transmissions in an internal combustion engine vehicle. Well, there are actually more if you count the less common types, such as continuously variable transmissions (CVT), but we won’t get into that here. Let’s just stick with the two basic types of transmissions: manual and automatic. What are the key differences between the two?

Manual transmissions require the driver to put in a little more work when driving. A manual transmission allows the driver to physically shift the vehicle into different gears using a clutch pedal and gear shift. In order to move the automobile forward and to increase speed, the driver must manually shift gears. An automatic transmission, however, does the grunt work for the driver, changing gears fluidly as the driver pushes on the accelerator.

Manual transmissions are more labour intensive in terms of actually driving. It’s largely for that reason that automatic transmissions are more common in Canada. But there are benefits to manual transmissions. For one, vehicles with a manual transmission tend to be less expensive than their automatic counterparts. Second, they usually get better fuel economy, too. Lastly, some drivers prefer manual transmissions because they enjoy having more control over their vehicle. However, if you’re not used to manual transmissions, they can be a bit confusing. For example, what do you do with the transmission oil?

Transmission oil

Both automatic and manual transmissions require lubrication, but manual transmissions typically don’t use transmission fluid. Manual transmissions can use regular motor oil or heavyweight hypoid gear oil. As ever, you should always check the auto manufacturer’s booklet that came with your vehicle to see which type of transmission oil they recommend for your manual transmission. And to see how often they recommend changing your transmission oil.

Transmission oil change

So, do you need to change transmission oil? The answer is, yes, you do. Just like automatic transmission fluid, manual transmission oil must be changed periodically to ensure that your transmission runs smoothly. Most manufacturers recommend that manual transmission oil be changed on a slightly more frequent schedule than automatic transmission fluid. Manual transmission oil should be changed, roughly, every 50 000-95 000 kilometers. That’s a big range, so it depends on the age of your transmission and how you use your vehicle, eg: city vs. country driving; is yours a work vehicle that you use for tasks such as towing, etc.

School of Transmission

Your vehicle’s automatic transmission is a remarkable piece of machinery. It may be complex to understand how it functions, but a little knowledge can go a long way toward preventing a breakdown

The most complex and intricate system in your car is its automatic transmission – understanding how it works can help save you time, hassle, and money. Comprised of a series of mechanical, hydraulic, and electrical components, they are all controlled by your car’s engine control unit, aka the powertrain control module.

A short drive to a nearby store means your transmission will likely shift about 25 to 30 times. Now imagine how many trips like that you make in a year and the impact they have on your transmission.

Shift Your Thinking about Your Automatic Transmission

Automatic transmission gear changes are monitored and executed by your vehicle’s internal computer. A torque converter uses the pressure and flow of transmission fluid to not only regulate the gear changes but also to allow the engine to continue running even when at a full stop. It also makes for a smoother shifting between gears.

When fluid levels in the transmission drop, so does the pressure that controls the shifting of gears. That can cause friction and less effective cooling, in turn leading to damage and potentially expensive repairs.

Recognizing Automatic Transmission Warning Signs

Preventing a breakdown from stranding you at the roadside requires insight into the warning signs your car will send if you’re on the cusp of experiencing a transmission-related problem. These warning signs include:

  • Grinding, rattling, or whining noises when changing gears or problems shifting gears
  • A delay in movement or your car jerks or shakes as it accelerates
  • Your transmission fluid is low, or you notice it pooling beneath the engine where you park
  • If you check your transmission fluid and see it’s not a reddish colour
  • You smell a burning odour while or after you drive

If you suspect your vehicle’s automatic transmission isn’t performing properly, or if you have questions about preventative transmission maintenance, contact us. Take advantage of our free 21-point multi-check inspection and avoid the cost and aggravation associated with a failing transmission.
