How do I change the oil in my transmission? How to change the oil of the car transmission

Use original manual transmission lubricants. This aluminum alloy engine lower guard plate is installed, light weight, good heat dissipation, and has a certain protective effect on the engine and gearbox! Remove the under-engine guard first.

Remove the hexagon socket manual transmission drain screw. Released the manual transmission lubricating oil that had traveled for kilometers. In other words, it was the first time that the manual transmission oil had been changed.

Due to long-term use, the lubricant has turned black! After the oil is discharged, tighten the oil drain screws. Remove the reversing light switch on the manual transmission.

When the newly filled lubricating oil overflows from the screw hole of the reversing light switch, it indicates that the filling is completed, and the reversing light switch can be installed as shown in the figure. Replace the engine oil, drain the old oil, unscrew the old oil filter, and replace it with a new original oil filter. Observe the oil filling hole, there is no sludge or dirt, indicating that the engine is normal.

Added with fully synthetic, high-quality motor oil. After filling, the car is inspected for oil leaks in the oil filter, transmission and engine. This is the middle part of the underbody, and everything is fine after inspection!

Check the independent suspension and spare tire seat at the rear of the vehicle and everything is fine! After checking that everything is normal, the engine underguard plate is installed, and the work is called. The maintenance time was only an hour, and the efficiency was very high.

In addition, some fuel injection pumps or transfer pumps that use forced lubrication can also cause the lubricating oil to be diluted by the fuel. After the lubricating oil is diluted by the fuel, the viscosity will drop significantly, affecting the formation of the lubricating oil film, at this time, the lubricating oil pressure will be reduced, and the lubricating oil will have an obvious fuel odor. At this time, it is necessary to check the path of fuel entry and replace the lubricating oil.

For the method of changing the oil of the automatic transmission, don't think that everything will be fine if you hand over the car to the maintenance shop, because there are currently two ways to change the oil, and the effect is very different. At present, many maintenance shops use the traditional natural oil drain method to change the automatic transmission oil for car owners. This method is commonly known as "hand change" in the industry, that is, to open the oil drain screw of the automatic transmission and let the oil inside drain naturally.

This is an old way of changing oil, which has the advantage of being easy to operate and less time-consuming, and the disadvantage is that the oil change is not thorough, and only a quarter to a third of the old oil can be discharged, which is about 4 liters. At present, a considerable number of service shops follow this way of changing oil, because after adding oil, the old and new oil are mixed, and the oil in the automatic transmission is still in an impure state, so it can only shorten the oil change time, and it is not surprising that some service stores require an automatic transmission oil change every 2-30,000 kilometers.

The replacement of the circulating machine uses a special machine to simulate the working state, and all of them are replaced at one time. The advantage is that the automatic transmission oil can be changed to 80%-90% with the circulation machine, because 70% of the automatic transmission oil is in the oil channel, so the replacement is more thorough. The following is a simple summary of the steps, first find the joint of the external circulation machine of the vehicle, and determine the oil inlet pipe or outlet pipe after finding the joint, then connect the pipeline of the circulation machine to the circulation machine, and inject automatic transmission oil into the container.

You can replace the transmission oil (note: when replacing, pay attention to observe whether there is oil leakage in the pipeline) precautions, after the replacement should be completely checked to ensure that there is no oil leakage and other problems, after the replacement is completed, the test run should be carried out, and then re-checked, the entire oil change, should be handled carefully to avoid unnecessary loss of oil.

The car to change the transmission oil first to the inside of the gearbox to drain the oil, and then the gearbox bottom shell oil drain screw tightened, and then open the hood to add a new gearbox oil, the specific operation steps of the car to change the gearbox oil are as follows:

1. Unscrew the oil drain nut of the bottom shell of the car gearbox.

2. Use a basin to catch the transmission oil released by the car, and remember to tighten the oil drain nut of the bottom shell of the car transmission after it is cleaned.

3. Open the door on the cab side of the car.

4. Pull the hood switch on the left side of the driver's leg of the car.

5. Lift the hood of the car's engine upwards.

6. Use the support rod to support the engine hood of the car, and ensure that the support is firm to avoid danger during operation.

7. Unscrew the gearbox oil cap of the automobile gearbox.

8. Add transmission oil.

9. The oil level of the automobile transmission can be in the middle of the upper scale line and the lower scale line.

Hello. Generally, when changing the transmission oil, most of the screws on the transmission oil bottom are removed to leak the old oil and then add new oil, but this can only replace about 30 new oil, and 70 old oil is still left in the gearbox. If the oil is changed by removing the oil pan, an oil change rate of 70% can be achieved, which in fact ensures the health of the gearbox.

But at present, the better oil change method is dynamic oil change, using special gearbox cleaning equipment, in the process of gearbox operation, the old oil is fully circulated, discharged cleanly and then add new gearbox oil, so that the oil change rate is as high as 90 or more.

Hope it helps.

It is recommended to replace the manual transmission car for about 60,000 kilometers, drive for a period of time before replacement, after the transmission oil temperature rises, release the old oil, and add new oil;

It is recommended to replace the automatic transmission car for 40,000 kilometers, and special oil change equipment is required to cooperate with the oil change in order to replace it more thoroughly.

Hello, it is generally recommended to replace the manual transmission oil once at about 60,000 to 80,000 kilometers, and the automatic transmission at about 60,000 kilometers. It is best to change the transmission oil in a professional place.

The gear oil in the automobile gearbox needs to be replaced, generally about 60,000 kilometers of maintenance, which needs to be pumped out.

The transmission oil is generally replaced by gravity oil change, which is not easy to operate, so it is recommended to go to the store to change it.

Hello, the replacement of transmission oil is generally taken by gravity or circulation machine replacement, gravity replacement is simple but not thorough, the transmission has no residual oil more, the circulation machine is more thorough, and the time will be longer!

This one goes to the 4S shop or repair shop to replace it, and you need to raise the car to replace it, and the repair shop is about 500 yuan.

Transmission! There are two ways to change the oil, one is to use gravity to change the oil, directly from the screw of the oil pan, and add a new one! Another way to change the oil is to use the method of recirculating the oil, but to use the machine, and the amount used is relatively large, the gravity oil change may only use four liters is enough, but if the oil is recycled, it will need to use more than ten liters.

Hello, the transmission oil of this car needs to be replaced by a professional in a 4S shop or repair shop.

Hello, the vehicle's transmission oil change can be drained and emptied on its own, and then the oil is added.

The oil of the automobile transmission needs to be changed by the machine cycle, so that it can be replaced relatively cleanly.

If you are a manual transmission, it is recommended that you use a gravity oil change. It is the so-called Mandarin that has to remove the oil pan screw to drain the oil. If you are in automatic transmission, it is recommended that you use it.

Automatic transmission switch oil change. Because this oil change method can reach more than 95%, replace the new oil. This extends the life of the gearbox.

However, the price of this type of oil change is generally more expensive than that of heavy force oil change. Thank you, hope it helps.

Hello, the transmission oil of the car, one is replaced by a mechanical cycle, and the other is the use of gravity draining, you can go to the repair shop to have a look.

If you want to call a professional to help you get this transmission oil, you can go to a 4S shop or a regular repair shop to change it.

This problem must go to a professional place to replace yourself, if you don't have a machine, it will definitely be difficult to change.

The time of changing the car oil, the first oil of the new car is replaced within 2000 kilometers, and then every 5000 kilometers to do ordinary maintenance, the gasoline filter can not be changed often, generally every 50,000 kilometers or every year when the winter is about to change, high-end cars are recommended to be replaced at 1 to 20,000 kilometers, as for the gear fuel tank, the manufacturer's standard is generally 20,000 kilometers to change.

There are three main ways to replace a transmission oil leak base:

Here's a description of the transmission fluid:

Reasons to change the transmission oil:

The viscosity of the transmission oil used for a long time will become thinner, resulting in reduced lubrication performance, reduced sealing performance, increased resistance, and increased wear, resulting in unstable pressure and affecting the working accuracy of the hydraulic system. The transmission control accuracy decreases, the gear shift accuracy decreases, and the ride and response speed will be affected. After deterioration, the cooling performance and oxidation resistance of the engine oil will be reduced, which will easily lead to problems such as excessive oil temperature, a vicious circle, and further shorten the life of the oil and transmission parts.

Manual transmission vehicles that need to manually operate the gear shift generally need to change the transmission oil once when driving about 50,000 kilometers. The pressure of the automatic transmission is relatively small, and the transmission oil needs to be changed once when driving about 80,000 kilometers.

How to change engine oil and transmission oil:

1. Remove the oil change screws and add as much oil as you want. Removing the oil pan and changing the oil will be cleaner than the former. The manual transmission has no requirements for transmission oil, and the internal filling is gear oil;

2. As long as the manual transmission oil is not lacking, keep normal lubrication, and there is no need to replace the gear oil when the car gear is smooth and the gearbox has no noise, and it can be used all the time;

3. If the gear is not smooth, it is recommended to change the transmission oil. Many manual transmissions have not been changed because the gearbox can last until the car reaches the end of its life. Under normal circumstances, it is necessary to change the transmission oil every three years or every 50,000 minutes of driving.

Step 1: Connect the switch.

Open the hood, wrap the fender pad, lift the vehicle, simply check the chassis of the vehicle, find and confirm the location of the heat dissipation oil pipe of the gearbox, select the corresponding connection joint, and connect the two pipelines of the switch with the inlet and return oil pipes of the gearbox respectively.

Step 2: Check the old fluid.

Start the vehicle, connect the smart switch to the battery, turn on the smart switch, observe the cleanliness of the old oil from the old oil display tube, if there are metal particles, sludge, friction plates and other impurities found in the old oil, the inside of the gearbox may have been worn, and further repair is needed, and it is not suitable to replace the transmission oil now.

Step 3: Replace the filter.

Turn off the engine, lift the vehicle, untie the oil screw, and release the old oil. Use a meterable container to collect the old fluid, disassemble the oil pan, and put the oil inside the oil pan into the old oil container at the same time. Replace the oil pan gasket and, if possible, the filter, but the location of the filter can vary greatly from vehicle to vehicle.

Step 4: Cycle cleaning.

Add the new oil to the switch, turn on the function of "filling new oil" on the switch, set the amount of added to the old oil released and start the vehicle, turn on the "cycle cleaning" function of the switch, and the driver needs to control the shift mechanism to cycle and clean each gear, and the cycle cleaning time of each gear is controlled within 5-10 seconds, and the total cycle time is 5-8 minutes.

Step 5: Equal Swap.

After the cycle is over, stop the engine, add new oil to the switch again, and select the "Equal Oil Change" function, and after completion, observe whether the color of the old and new oil on the switch is consistent. If it is consistent, the operation is complete. If not, continue to add new oil until the color of the old and new oil is consistent.

Step 6: Check the liquid level.

Check whether the oil quantity is sufficient, the gearbox with the dipstick, and check the position of the dipstick scale; If there is no dipstick, lift the vehicle, open the inspection bolt, too much oil will overflow from the inspection bolt hole, if there is no spill, add new oil through the smart switch according to the actual situation, until there is oil overflow. Please note that checking the fluid level line needs to be at the proper transmission oil temperature.

Step 7: Road test drive.

Get out of the car, turn off the engine, turn off the smart switch, remove the connector, connect the transmission heat dissipation oil pipe, observe whether there is oil leakage, and wipe the oil stains and dirt on the surface.

Transmission oil change method:

1. Frame the car first, and then, find a large utensil to pad under the car for use with waste oil. Use a suitable screwdriver to remove the gearbox and shell, at this time there will be some gearbox oil outflow, pay attention to dodge;

2. After a few minutes, when part of the oil is about to dry, remove the last oil tank, pay attention to carefully hold it with your hands, there is still a large amount of waste oil here. When you take it off, you will see that there is a lot of stain left on the bottom of the sump; Carefully remove the transmission oil filter, and you can clearly see the solenoid valve used to control the gear changeover;

3. Take off the oil bottom gasket to remove the surrounding buried tung stains, and if the gaps are not clean, you can use tools. Due to the long time, the rubber on the oil gasket sticks to the edge of the machine and is not easy to clean, and a small scraper is needed to remove it, and at the same time spray some carburetor cleaner, which will save some effort, and the cleaning will be more thorough, wipe all the cleaned transmission oil filter devices with cotton silk, and then install them one by one. Remind everyone that the filter is generally used once, and when the oil is changed, it is necessary to replace the new filter and oil gasket;

4. Wipe the surface of the replacement parts clean, and there should be no water and oil stains, otherwise it will easily cause oil leakage; Install the clean oil groove and oil gasket together, and pay attention to the bend tank must be tightly seamed to avoid oil leakage. Clean and wipe the oil filter shell clean, install the cleaned shell, fix the two diagonal corners first, and then tighten them all;

It is best to use the original oil, because when the automatic transmission changes the oil, a part of the oil can not be cleaned, and it still remains in the gearbox, and it may react after mixing with the remaining oil in the gearbox after filling other brands of oil, resulting in damage to the gearbox. Not a high-quality oil is suitable for any model, and changing to a high-speed oil may not be better than the original oil.
