What is a Transmission Oil Change?

What is a Transmission Oil Change?

When doing some online research about transmissions you might come across some terms and some ideas with which you are not familiar with. There are automatic transmissions and manual transmissions. Do you know the difference? There is transmission fluid and there is transmission oil? Are they different? Does transmission fluid need to be changed? Does transmission oil need to be changed? Well, don’t worry, this article will try to answer some of those questions.

Automatic vs. Manual Transmissions

A manual transmission requires more work from the driver. A manual transmission needs the driver to physically shift the vehicle into different gears, using a clutch pedal and shift knob. In order to move the vehicle forward and reach higher speeds, the driver must manually shift gears to get to the desired speed. An automatic transmission, on the other hand, does all the grunt work for you, changing gears fluidly as you push on the gas pedal.

Both automatic and manual transmissions have their pros and cons. Automatic transmissions are easier to use but manual transmissions give the driver more control of the vehicle. Vehicles with manual transmissions are more likely to be cheaper and there is some evidence to suggest that they are more fuel efficient. And the reason for going over automatic and manual transmissions will become clear soon.

Transmission Fluid

Transmission fluid allows the transmission to work. Transmission fluid works as a lubricant for the parts within your transmission. Transmission fluid is optimized for the functions of the transmission. These functions include valve operation, brake band friction, and the torque converter. Transmission fluid is required in all automatic transmissions.

Transmission Oil

While all automatic transmission require transmission fluid, this is not true for all manual transmissions. Some manual transmissions do use transmission fluid, but others use gear oil or sometimes engine oil. Sometimes gear oil is called transmission oil. The transmission oil lubricates the manual transmissions and other parts involved.

Transmission oil has a noticeable odour because of its sulfur-bearing anti-wear compounds. These compounds are necessary to reduce high sliding friction by the helical gear cut of the teeth. In a motorcycle in which the clutch is bathed in transmission oil, there is usually nothing separating the lower part of the engine from the transmission, so the same oil lubricates both the engine and transmission.

Transmission Oil Change

The transmission fluid in an automatic transmission will typically need to be changed out every now and then. The same is usually true for transmission oil in manual transmissions. However, speaking very generally, transmission oil changes are needed less frequently than transmission fluid changes. Some auto manufacturers claim that the oil never needs to be changed, as their transmission is a closed circuit. However, the oil might need changing due to other transmission problems, repairs, or leaks. These claims should be treated with a critical eye and you should ask a technician at a transmission shop if your specific vehicle might require a transmission oil change.

5 of the Most Common Transmission Problems

Most Common Transmission Problems

Are you worried that there is something wrong with your transmission? Are you worried that something might happen to your transmission? It’s not always easy to tell when your transmission is acting up. With some parts of your vehicle, a problem can be plain to see, but with the transmission? This is not always so. But don’t worry, we’re here to help. Here are five of the most common transmission problems.

No response

We begin our list of the top five most common transmission problems with one of the easiest ones to notice. When you shift gears in your vehicle, you expect your vehicle to, you know, shift gears. But sadly, this does not always happen. From the moment you put the key in the ignition and shift from park into drive, your vehicle should immediately go into the correct gear. For automatic transmissions, there is sometimes a delay before you feel the gear engage when trying to shift gears. This is usually a transmission problem.

What’s that smell?

Unless you’re sitting by a crackling campfire or fireplace, the smell of burning is rarely a good thing. And so too is this true for transmissions. If you smell burning coming from your transmission, you have a problem. This is often caused by low quality or quantity of transmission fluid. When transmission fluid breaks down, this causes increased friction the transmission will overheat.

Noise in neutral

Vehicles make noise. That’s what they do. When your vehicle is in neutral, however, it shouldn’t be making too much noise. If your transmission makes a great deal of noise while in neutral, you could have an issue. Luckily, this common problem can often be resolved by topping up or changing your transmission fluid.

Dragging Clutch

A manual transmission is more likely to experience a dragging clutch. If the clutch disk doesn’t disengage the flywheel when the clutch pedal is pressed, your clutch is dragging. The clutch still spins with the engine, though, and this makes it much more difficult (and sometimes impossible) to change gears. A dragging clutch will also often make a grinding noise when you try to change gears.

Obviously, you don’t want to experience any of these five most common transmission problems. But, luckily, a dragging clutch is often one of the more inexpensive transmission problems to get repaired. Frequently, the cause of a dragging clutch is an overabundance of slack in the clutch pedal. When there is too much slack, the linkage between the clutch disk and pedal it can’t pull  the clutch disk away from the flywheel.

Low fluid

As mentioned before, transmission fluid is vital to the health of your transmission. That is why whenever you see a patch of transmission fluid on the pavement where your car just was, you need to get that leak repaired right away. You should routinely check your transmission fluid levels to make sure you have enough fluid there. Furthermore, you must make sure that your fluid is still of good quality. Discoloured or malodorous transmission fluid is damaged transmission fluid.

What’s Involved in a Transmission Service?

Mister Transmission offers various types of transmission servicing, depending on your car’s needs. Here we explain the 5 most common transmission services.

A transmission service is part of your routine maintenance, just like replacing your engine oil. Here we’ve laid out the different types of transmission services we offer at Mister Transmission, including why they are important and what each service includes.

Automatic Transmission Fluid Exchange:

Transmission gears deliver power from the engine to the drive wheels, shifting automatically to provide the best power and efficiency for your driving speed. A special transmission fluid cools and lubricates the gears. Over time, this fluid degrades, and its lubricant qualities diminish. Changing the fluid at the correct intervals can help prevent premature wear and damage to the transmission.

This service includes;

Removal of the old transmission fluid and replacing it with new, clean fluid of the grade recommended by your vehicle manufacturer.

Automatic Transmission Drain and Fill:

Automatic transmission fluid lubricates, cools and cleans internal components of the transmission. It also helps to maintain the hydraulic pressure necessary for the transmission to function. The additives in the transmission fluid can be depleted over time.

This service includes;

  • removing the transmission fill/drain plug to remove the old automatic transmission fluid
  • reinstalling transmission fill/drain plug
  • refilling the transmission with new automatic transmission fluid to the proper level

Automatic Transmission Filter Replacement:

The automatic transmission filter helps remove dirt and contaminants from the automatic transmission fluid.

This service includes;

  • removing the transmission pan
  • removing the old transmission filter and replacing it with a new transmission filter
  • removing the old gasket material
  • replacing the pan gasket with a new gasket and reinstalling the pan
  • refilling the transmission with new automatic transmission fluid to the proper level

Automatic Transmission Fluid Exchange & Filter Replacement:

Automatic transmission fluid lubricates, cools and cleans internal components of the transmission. It also helps to maintain the hydraulic pressure necessary for the transmission to function. The additives in the transmission fluid can be depleted over time.

This service includes;

  • changing the fluid in the transmission system, including the torque converter and transmission cooler
  • removing the transmission pan
  • removing the old transmission filter and replacing it with a new transmission filter
  • removing the old gasket material
  • replacing the pan gasket with a new gasket and reinstalling the pan
  • refilling the transmission with new automatic transmission fluid to the proper level

Manual Transmission Service:

Manual transmission fluid provides lubrication to gears, bearings, shafts, and other internal components. Heat, pressure and friction can slowly breakdown the additives in the manual transmission fluid. In addition, small particles of metal may come off the gears as they wear and these metal particles can mix with the fluid. Fluids can also become contaminated with water.

This service includes;

  • draining or evacuating the old manual transmission fluid
  • filling the manual transmission fluid with the manufacturer’s recommended type and quantity of new fluid

The net result of all these services is to provide better lubrication, improve the holding ability of the friction components, and reduce heat. This means your transmission works better, longer. Therefor you are less likely to face a major transmission repair.
Mister Transmission offers all of these services, and will be happy to explain the details to you.

A complete transmission service should include:

  • removing and examining the sump or pan (where possible)
  • replacing or cleaning the screen or filter
  • cleaning the pan
  • reinstalling the pan with a new pan gasket

The Difference between Synchronized and Unsynchronized Gearing in Manual Transmissions

There’s a good reason why large commercial vehicles, motorcycles, and race cars still employ an unsynchronized gearbox

For stick-shift adherents, there is no greater joy than driving a car with a manual transmission. But what’s behind the mechanics of changing gears? And from a driver’s perspective, how does manual transmission synchronized gearing compare to manual transmission unsynchronized gearing?

Most modern urban vehicles fitted with manual transmissions likely feature a synchronized gearbox also referred to as a synchro-mesh gearbox. This device keeps the gears in mesh and rotating, or they can be locked to the shaft. In other words, when you change gears, you’re locking different gears to the transmission’s input or output shaft, thereby allowing you to increase your vehicle’s speed or slow it down. The manual transmission’s synchronized gearbox is what helps you smoothly lock gears into place.

It was a remarkable evolution in manual transmissions because the synchronizer did away with the need for motorists to perform double-clutching – releasing and re-engaging the clutch twice whenever changing gears – a requirement to operate a vehicle with a manual transmission unsynchronized gearbox.

Why the Manual Transmission Unsynchronized Gearbox Still Matters

A manual transmission unsynchronized gearbox is an older design (possibly the earliest design of a manual transmission) that required a lot of effort and skill on the driver’s part. It included a sliding-mesh gearbox, and the driver would need to carefully time when to shift gears to ensure the gears were rotating at the same speed, which was no easy feat. Do it improperly, and you’ll hear grinding and other noises.

However, the unsynchronized gearbox continues to exist. You will often find them installed in transmissions for large commercial vehicles such as heavy trucks and farming machinery, as well as in motorcycles and high-calibre race cars. Why? For two reasons: synchronized manual transmissions are more prone to breakdowns, and shifting gears on a synchro-mesh gearbox is slower than the unsynchronized version.

Manual Versus Automatic Transmissions

Is driving a car with a manual transmission more economical than one with an automatic transmission? The answer lies in being able to distinguish myth from fact

In the automotive world, it’s an enduring argument that may only reach a conclusion should auto manufacturers completely shift away from offering standard vehicles in North America: the manual versus automatic transmission divide.

Year-over-year, there are fewer cars and trucks sold with manual transmissions. Even high-end sports cars more commonly have automatic transmissions than in years past. Though stick shift adherents will insist there are considerable financial benefits to owning a car with a manual transmission, many of their arguments don’t hold up anymore.

Stick Shift Myths
Drivers who drive vehicles with manual transmissions are passionate about being stick shifters, and for good reason. If you know how to operate a manual transmission, it adds to the enjoyment of cruising the tar plains.

However, when it comes to defending the benefits or differences between automatic or manual transmissions, there are more myths than facts fans of standard transmissions tend to cling to, including:

  • You have better control of your car especially in the wintertime
  • Vehicles with manual transmissions cost less to purchase and maintain
  • Cars with manual transmissions are more fuel efficient
  • They deter thieves from attempting to steal your car
  • They’re ideal for sports cars or vehicles hauling heavy loads
  • Slowing your car by downshifting instead of braking preserves the brake pads
  • You pay more attention to driving because both of your hands are required to drive

These pro-manual arguments have been in vogue for decades, and at one time, there was some validity to them. But the advancements in automotive technology and automatic transmissions is such that these viewpoints have little or no basis in fact or any scientific evidence to support them.

For instance, fuel mileage has dramatically improved in modern automatic transmissions, and it’s significantly cheaper to replace brake pads than a manual transmission. The cost of transmission repairs in either manual or automatic transmissions is, for the most part, comparable. Arguments to the contrary are beginning to slip like a worn-out gearbox.

Of all the pro-manual arguments above, there is one possible exception that may be true: In our mobile device-obsessed world, you’d need to be an expert juggler to drive a standard vehicle and play with a mobile phone at the same time. Texting and driving are illegal. Chalk one up for stick enthusiasts for promoting safe driving.

Automatic Transmissions Are the New “Standard”
Though it is fun to drive a car with a manual transmission, that may be the only legitimate argument stick enthusiasts can make. That’s because the technology in today’s cars is at exceptional levels of intricacy. As a result, it could be argued that today’s automatic transmissions are the “standard” in almost all vehicles.
