When something is wrong with your car, it will most likely convey auditory or tactile signs. Most automotive parts, particularly those linked to the engine and gearbox, are lubricated with special oils, making them essential for optimum operation and extending the life of the vehicle by preventing early wear.

The gearbox fluid should be changed without hesitation when the car shows evident warning indications, even if it should not be updated sooner than 25. 000 miles or annually as a stringent preventative step.

What is the automatic transmission oil?

Transmission is automatic. Oil is the fluid used in automatic transmission vehicles. To distinguish it from other types of oil, it is frequently tinted red or green.

Why do you need to change the transmission oil?

Contamination with iron pellets, sprinklers on sprockets, or other mechanisms is unavoidable for any transmission oil, and it is therefore advised that it be replaced in order to keep its original qualities.

When should you change the transmission fluid?

Even though it is changed less frequently than engine oil, the operation is advised according on the type of use of the vehicle.

intense use (unique to distribution vehicles, passenger transportation, and so on) and typical use (specific to personal cars). The kind of transmission is another factor that influences the transmission oil exchange interval. Manual or automatic? The oil in automatic transmissions should be changed more frequently than in manual transmissions.

Check the automobile manual to ensure you change the automatic gearbox oil at the proper intervals. There you will discover all of the instructions and recommendations for maintaining all of the car’s components. Volkswagen, for example, recommends replacing the transmission oil every two years.

When you hear or feel one of the following symptoms, the best time to change the fluid is when you hear or feel one of the following symptoms, my suggestion to you is to request a check in to an authorized service since there is a very good probability that you will need to replace the transmission fluid:

1. Physical difficulty when changing gears

The gearshift must be quiet and smooth. You will notice that gears change with delay and difficulty, or at times that appear to be sooner or later depending on how the automobile is actually running. When the vehicle is equipped with a manual transmission, shifting gears may become impossible.

2. Scratching noise or squeaking noise when changing gears.

Aside from being annoying, these noises are a strong indication that something is amiss with the transmission. When the engine is running, the metal-on-metal rubbing and loud noises should cause you to stop and check the transmission fluid level. The color perception of this liquid should also be included in the check. If you observe a hue other than bright red or bright green, it is apparent that the transmission fluid needs to be replaced.

3. Shocks that do not seem to have an explanation.

Transmission oil contamination is the most common reason of the car moving suddenly or forward without any specific acceleration or braking control. A dirty oil should be replaced as soon as possible because the transmission’s natural lubricating flow will be disrupted.

4. The delayed reaction of the car when moving, after changing gears.

This phenomena can occur when changing gears when the transmission fluid is polluted with dirt, which is caused by a disruption in the usual lubricating flow that the fluid must provide. This delayed reaction could persist from a few seconds to many minutes, indicating substantial transmission fluid contamination.

Decoupling from the selected gear.

What Happens If You Put Oil In The Transmission-3

When the transmission fluid becomes polluted with dirt, the optimal oil flow in the transmission may be compromised, or some deposits in the system impact the pressure gauges that play a part in preserving the selected gears. For these reasons, it can create the decoupling from the selected gear at random, with no prior indication.

If you have experienced any of these scenarios while driving, it is obvious that a transmission and transmission fluid check is necessary as soon as possible. When the transmission fluid’s color is other than intense red (or green) or has a burning stench, it’s likely that simply replacing it will solve the problem. If they persist, it is more than that, and a comprehensive examination of the transmission processes is required.

The transmission, like the engine in your automobile, requires a particular oil to preserve its components from damage or corrosion. Maintaining the optimal transmission oil level is critical for the efficient operation of your brakes and vehicle.

How do I check the transmission oil level?

  1. Examine the user handbook. Is your transmission manual or automatic? A manual gearbox does not normally include an oil metering rod. These are pre-filled and do not require refilling. Only change the fluid as necessary for repairs.

Step 2: Identify the oil measurement rod. Typically, the transmission oil measurement rod is shorter and red. It might even be marked if you’re lucky.

In the case of rear-wheel drive automobiles, the rod is normally located in the compartment on the side closest to the passenger seat. In automobiles with front-wheel drive, the rod is on the driver’s side, on both sides of the transmission.

If you can’t find it, consult your car’s owner’s manual. Many cars no longer have the oil measuring rod, which has been replaced by an encased device that necessitates a considerably more involved procedure to check the oil level.

Electronic testing technologies, such as computer scanning, are used in this process. As a result, the drivers of these vehicles are no longer proficient enough to check the level of automobile oil on their own. If you are one of them and your vehicle lacks a transmission oil measuring rod, have it checked at a repair center multiple times a year.

If your vehicle still has a gearbox oil measuring rod, we recommend doing a routine inspection.

  1. How do I check the transmission oil?

Remove the rod and clean it with a clean cloth. Then insert it again and wait 5 seconds before removing it and checking the oil level. Also, add oil as needed and always use the recommended one per the manufacturer’s instructions.

Every time you add the progressive oil, check the level. It is simple to add oil but much more difficult to remove it. Check for leaks if you need to add more than a liter of oil to your transmission.

How to check the transmission oil properly?

Look at its color and smell.

Color is crucial since it can instantly show when the oil needs to be changed. A high-quality oil should always be the same hue. Typically yellowish brown and semitransparent. The liquid for the automatic transmission is lighted red. If the liquid gets dark red or brown, it should be replaced. Also, if the odor has burned or contains various particles, you must perform a service check. What exactly is a transmission service? This entails replacing the oil filter before adding transmission oil. Can you check the transmission fluid on your own now that you’ve learned everything?

Why should the oil level be checked for an automatic transmission?

The transmission oil is the transmission’s lifeblood. The fluid generates the hydraulic pressure needed for the transmission to operate. It also serves to cool and lubricate the transmission. When the level falls below a certain threshold, the pump can suck air into the system. The entry of air into the hydraulic system disrupts the oil flow in the gearbox. When the fluid level declines, it is quite easy for damage to occur.

How to check the oil level for the automatic transmission?

The process for rod transmissions is the same as described previously. Many Ford, Toyota, General Motors, and European and Asian automobiles now lack oil level gauges. The manufacturers’ pattern is to remove the rods from the automatic boxes. Newer transmissions are far more sophisticated than older models, and fluid level is crucial. Checking the oil level necessitates extremely precise techniques. If you want to take it a step further, here’s how to change the gearbox oil:

  • Drain the fluid from the transmission: first, disconnect the cooling line that connects the transmission with the radiator. Connect a piece of rubber tube to the pipe and place the free end of the rubber tube over an empty container. Start the engine and let it run. The oil will flow from the cooling pipe into the container. When the leakage stops, stop the engine. Then you can reconnect the cooling pipe to the radiator.
  • Remove the screws that secure the drain tray to the bottom of the transmission.
  • Clean oil pan for the transmission.
  • Replace the filter.
  • Replace the gasket.
  • Install the tray. Once the filter and gasket are in place, place the tray back on the transmission. Screw the bolts by hand, then with a wrench to tighten them. We recommend not to tighten them too much, in order not to damage the wires in the transmission and not to twist the tray.
  • Pour Transmission Oil: Dexron III ATF oils are the most common, but check also in the car manual to choose the fluid recommended by the manufacturer (also check the quantity).

How much oil do I need for a complete change?

About 2 2.5 liters of oil can be stored in the transmission. If you use this amount and the oil level does not reach the top of the gearbox, you may have some oil leaks. An emergency visit to a car service is advised in this circumstance. Also, remember to dump the spent oil before replacing it and properly recycle it.
