Transmission Factor Overheating and How to Prevent It

Transmission Factor Overheating and How to Prevent It – Dear homeland automotive lovers, this time I will discuss things about the transmission experiencing overheating. As we all know that transmission is one of the important components of several other important components. Therefore, it is important to pay attention to whether the automatic transmission is overheating or not.

Heat (in everyday context) or the term heat in engineering language is the main cause of transmission to suffer fatal damage. It’s not the fault of the product or the aging components. This heat accounts for nearly 90% of which causes fatal damage to the automatic transmission.

Excess heat in the transmission allows the onset of various kinds of problems that arise, including damage to cells, cracked transmission gears, slipping transmission bands, bearing damage (lava), non-operating solenoids, and delays in clutch work. For certain parts, very high temperatures can cause them to break.

Most common causes of overheating (too high heat) include solenoid problems, oil leaks, or too little (not enough) oil and can also be caused by burnt or worn oil (too long without being replaced). Another generating factor that causes overheating is if you always operate in areas with high ambient temperatures, often stop while traveling but the engine remains in a state of the nose and also traffic jams on the highway and heavy loads that must be suffered by your vehicle.

How Does Oil Cool A Transmission?

The oil contains chemical additives that can provide the ability to perform lubrication and pressure when there is a change in transmission gears. But this is not the main function. The main function of transmission oil is to remove or reduce heat. Rotating gears, expanding springs, and twisting of the turbines generate friction.

This friction generates a large amount of heat, which can cause cracking, erosion, and other hazards in transmission components if the heat is not removed or reduced as quickly as possible.

For this reason, oil is designed to absorb this heat as it flows through the moving parts. The oil then carries the heat away from the transmission to the radiator, where the hot fluid is forced through a special cooling chamber that uses aluminum fins to remove heat from the ATF.

When the air flows (through) the radiator, the heat is removed and the cold fluid is then returned to the transmission via another line. If heat cannot be dissipated and then returns to the transmission quickly, the transmission will overheat and the threat of damage will begin immediately.

Expected Oil Life vs Temperature

Without transmission oil, the life of the transmission will only last a matter of minutes when the transmission is working.

The lapse of time causes the organic components in the oil to degrade in function. This causes the oil to change from dark red, then brown, and then black. This also means that the oil has started to “thin”. It which of course significantly reduces the amount of heat carried away from the moving parts of the transmission component.

If your transmission is not checked (changed filters and oil) every 20,000 to 30,000 miles or every 12-18 months, the fluid will become ineffective. And the temperature will normally increase while the vehicle is operating.

The ideal operating temperature of the transmission oil is 175 degrees. Overheat occurs after the temperature passes 200 degrees. So if you drive a vehicle with the oil temperature at 240 degrees, your transmission will go into very serious trouble. And fatal damage will occur 4 times faster than fatal damage due to other causes. The oil that is under normal conditions and driving in a cool environment will make the fluid work properly, shifting gears can be done easily, and of course, make the transmission life longer.

Oil Temperature and Dangers

The color of the transmission oil can determine how big a problem the transmission is facing.
  1. 220-degree = erosion occurs on the surfaces of metal components.
  2. 240-degree = hardening of the seals.
  3. 260-degrees = transmission and clutch bands starting to slip.
  4. 295-degrees = seals, and couplings start to burn.

An insufficient amount of transmission oil will also cause the transmission to overheat faster. Without sufficient ATF to reduce (remove) heat, temperatures will soar past 260-degrees. Produces slippage in the transmission. Very worrying hazard in the clutch. Transmission bands are threatened with fatigue in operation. And of course, the threat of damage to the torque converter is unavoidable.

To prevent all of this from happening, check your transmission oil level at least once a month, or once every two weeks preferably if your vehicle is running high enough. And don’t forget to check every time the engine is turned on so that you will get an accurate reading of the amount of oil.

How to prevent the transmission from overheating

Transmission Factor Overheating and How to Prevent It
The easiest way to prevent manual transmission overheating is to change the transmission oil regularly.

Checking Transmission Oil Periodically

You should check your vehicle’s transmission oil at least once a month for possible causes such as the amount of oil in the transmission and a marked scuff or oil burn. This will make it easier for you to spot the early warning signs before they cause serious transmission problems. So that it can jeopardize and destroy your car’s transmission.

In addition to checking the amount and quality of transmission oil using an oil stick, be sure to inspect the underside of your vehicle so that the transmission oil pan is not dented. Because this situation allows oil leakage.

Change Oil on Schedule

Your vehicle’s transmission oil should be changed every 30,000 to 60,000 miles. You can replace it yourself or go to a repair shop where the oil is changed.

If you are driving in an area with high temperatures, lots of stops, and experiencing excessive traffic hours or vehicle loads, the oil should be changed more than usual, for example, every 15,000 to 20,000 miles. Your vehicle’s transmission will always be in good condition if the oil in the transmission can be maintained at a temperature.

Added External Cooling System

Your vehicle’s radiator is designed to cool oil. So be sure to replace the coolant in it according to the recommended instructions.

If your vehicle is bearing heavy loads, the radiator alone is not sufficient to keep the oil cool. In these circumstances, you should consider installing an external transmission cooler.

Increasing the Depth of the Oil Pan

If your transmission has overheated, then your transmission needs to be added to a larger (deep) oil pan. A larger (deep) pan adds extra oil to your vehicle. This added oil allows it to help absorb more heat and dissipate it faster from your car’s transmission. Aluminum pans are good material for storing heat.

Other Heat Sources

Wearing transmission bands, clutches, and solenoids can also cause your transmission to overheat. If these parts do not function properly, it can generate heat and cause overall oil heat.
