What is produced by the Ethereal gearbox will leak oil

Causes of transmission oil leakage failure:

1. The reason for oil leakage at the oil seal journal: the oil seal is aging and deformed, the oil seal spring falls off or the oil seal is in the wrong direction, etc., which will make the oil seal lose its oil blocking effect, and the oil seal should be replaced with aging and deformation, pay attention to the installation direction of the oil seal, and the side of the oil seal with a spring ring should be facing the side with oil. The journal is eccentric or concave, and the oil seal is not tightly matched, resulting in oil leakage, and the eccentric and concave journal should be replaced or repaired.

Second, the reason for oil leakage at the joint surface of the box:

1. If the end face of the box joint is damaged, the paper pad should be properly thickened at the damaged place, and if there is still oil leakage, it should be repaired by welding. 2. If the sealing paper gasket is damaged, the same sealing paper gasket should be replaced.

3. The screws of the box cover are loose and should be tightened in time.

3. Causes of oil leakage at the front joint surface of the bearing:

1. If the sealing paper pad is damaged, the same paper pad should be replaced in time.

2. If the fastening screw is loose, it should be tightened in a diagonal order, but it should not be overtightened to avoid damaging the paper pad. In addition, the vent of the gearbox is blocked, and the gearbox is isolated from the outside atmosphere when working, which causes the pressure in the box to rise, and also makes the oil seep out of the blockage. The ventilation holes of the gearbox should be kept open to reduce the pressure in the box and prevent oil leakage.

Fourth, the oil seal or flange is worn, and the gear oil exceeds the specified standard.

5. The clearance of each shaft end is too large, the seat hole and bearing are loose, the gasket is broken and the effect is lost, and the sealing washer is damaged or missing.

6. The processing quality of the surface of each seal does not meet the requirements of the product drawings, the oil seal is aging and failing, and the fastening bolts are loose.

7. Improper use of lubricating oil, such as: mistakenly adding the 18 parting hyperbolic gear oil used for the rear axle into the transmission (that is, mixed with the gear oil in the transmission), causing a large amount of foam in the lubricating oil in the box, resulting in a rise in the liquid level (with foam). The oil foam leaks into the bottom cover of the clutch housing through the inner wall of the bearing cover of the first shaft of the transmission, and in severe cases, the friction plate will be stained with oil.

The solution to the transmission oil leakage failure.

1. Oil leakage from the gearbox.

If you touch it with your hand at a junction near the gearbox, you can basically feel the oil. However, some oil stains are relatively clean, while others are mixed with dust. However, for this phenomenon, the general maintenance personnel explain it with anti-rust oil or oil during installation, and then check it after cleaning.

If there is still an oil leak after checking again, then the only way to remove the gearbox is to replace the oil seal.

2. Fault resolution.

The leak point is at the top of the gearbox, which is above the hydraulic fluid level of the gearbox. Due to the requirements of the assembly process, it is not necessary to be fully sealed here. In addition, the automatic transmission does not maintain normal pressure when working, and the problem of oil and gas release may occur.

The specific solution is to apply sealant to the leakage point, that is, to glue and seal the sludge after cleaning the surface, which does not require disassembling the gearbox structure. In addition, it is not excluded that there may be leakage problems in individual gearboxes, and if there are traces of liquid flowing on the surface of the oil, it is necessary for the owner to go to the shop as soon as possible to check it.

This car, people are not at ease, I feel that the oil leakage rate is still very high, and my technology version is also coming, tangled with this problem, hey.

Summary. Hello, I am your exclusive technician, attentive, careful, and dedicated to answering your car questions, and finding corresponding problem solutions and solutions for you!

Based on your question, the following analysis was conducted.

The analysis scheme is as follows:

Like this model, if you change the transmission oil, first of all, it is recommended that you choose the original transmission oil, if it is replaced in an outside repair shop, you can choose Aisin or ZF transmission, the overall quality of the gearbox of these two brands is still good, and there are more matching models.

Solution: This can be done in the repair shop with ZF or Aisin transmission fluid.

I hope my answer will be helpful to you.

CVT is maintenance-free for life.

Compared with other automatic transmissions, the change interval of CVT transmission fluid is slightly longer, usually every 2-3 years or about 6-80,000 kilometers.

CVT is maintenance-free for life mainly because it uses steel belt drive, and now the new design and technology have solved the problems of CVT in the past, using high-strength and high-quality materials, precision manufacturing technology, higher quality, and more reliable use, which makes CVT achieve the same life as the engine and maintenance-free for life.

Kiss.. Honda CVT transmission continuously variable transmission, 4S manufacturers and car maintenance manuals advocate replacement every 8-100,000 km; The oil change interval of the CVT transmission will be slightly longer than that of other car gearboxes, the general reason is that the CVT transmission structure technology needs to use the circulating machine to drain oil, and the suction power is relatively large, and the transmission is a precision component, which may deform the seal or even absorb it, so it will affect wear or oil leakage. Changing engine oil is a reason, and it is not recommended to use the pumping method; I think that foreign maintenance cars are basically gravity draining, and domestic pumping units are used to drain oil.

Now there are two ways to change the transmission oil: one is gravity replacement, and the other is recirculating machine replacement.

The principle of gravity oil change is not much different from changing engine oil, the oil drain screw is loosened, it is characterized by simple and less oil at a time, most of them can be used 4-6 liters at a time, and it is cheap, but the disadvantage is that it cannot be clean. The oil discharge of the circulating machine is to connect the machine to the interface of the transmission oil, and use the machine"Propulsion"New transmission oil,"Launched"The old transmission oil is characterized by being relatively clean, but it needs more transmission oil, most of which cost 10-12 liters or even 16 liters, and the price is more expensive.

Nissan Teana uses transmission oil for Nissan automobiles.

Nissan Teana transmission oil generally uses Nissan's CVT special oil, model NS3Teana generally has about 5L of transmission oil. Transmission oil up to 12L can be used for oil change with a circulating machine.

According to statistics, about 90% of automatic transmission failures come from automatic transmission failure.

If the transmission oil is not changed for a long time, the cold start of the vehicle will be weak; Working at high speed and high temperature, the oil will deteriorate and volatilize, which will aggravate the wear and tear of mechanical parts, and even damage;

When I go for maintenance, I am given three options: fully synthetic, semi-synthetic and regular motor oil.

There are two types of gearboxes.

The 4-speed AT uses ATF-D gearbox oil.

**The CVT gearbox oil used by Teana is the exclusive oil quality of NS-2.

It is the transmission oil, you can choose the 4S shop or you can buy it yourself and go to other maintenance shops to replace it

Use the vehicle model to match the special gearbox oil.

The gearbox and gearbox speed matched by each car are not the same, so the gearbox oil matched by each model has different lubrication effects on the gearbox parts, so it is advisable to choose to add the special gearbox oil matched by the original car when choosing to add, so that the gearbox can produce excellent performance in the vehicle driving, and at the same time, the gearbox oil can fully protect the gearbox parts, so as to bring more stable shifting enjoyment to the driver and passengers.

If the vehicle uses the gearbox oil added to other brands and models, due to the different gearbox speed, structure, and lubrication method of the gearbox oil in the gearbox of each car, the internal parts of the gearbox will be aggravated after the addition of the gearbox oil that does not match the model, so that the vehicle will break down in driving and generate unnecessary repair costs to the owner.

In addition, when adding the gearbox oil, it is necessary to pay attention not to let the gearbox fuel filler add any foreign matter, before adding the gearbox oil, it is necessary to pay attention to the vehicle in a flat engine in a flat posture to add measurement, in addition, some gearbox oil is different from winter and summer, before use, it is necessary to carefully read the scope of application of the gearbox oil and the engine gearbox model, and match the use.

1.Oil leakage in the engine and gearbox is mainly divided into the following types, one is open leakage, one is leakage, and the other is dripping oil.

2.Most of the reasons for the leak are because of the hole in your oil pan, which is a leak at this time, so you don't choose to continue driving, you should call for rescue, otherwise if you continue to drive, you can only overhaul the engine in the end.

4.Oil dripping situation, after staying in place for a period of time, you will find that there will be oil stains under the car, generally the oil pan seal is poor oil leakage, oil drain screw slip wire oil leakage, although the oil will not leak in a short time, but it is recommended to replace it as soon as possible.

5.Summary: In the end, someone must come back and ask, can the car still be driven if it is found that there is an oil leak?

As long as it is not a large-scale oil leakage, it can be opened, and if you find that there is a large-scale oil leakage or oil dripping, it is best to go to the 4S shop to replace the accessories, otherwise you will lose more than you lose when you run to the point where even the oil is leaking.

Hope, thank you!

Hello, the engine of this car is relatively durable, and it will not easily have oil leakage problems.

Hello dear, using the wrong transmission fluid will cause the transmission to burn out. Not only is the viscosity carefully calculated and matched, but the heat dissipation is also carefully designed. If the transmission oil's ability to carry heat is too strong or too weak, it will lead to a decrease in the efficiency of the heat dissipation mechanism, which will affect the heat dissipation and cause the transmission to burn out.

The first is to discharge the transmission oil in a timely manner. If there is special equipment, it is best to use the automatic transmission oil of the slag changing hall to follow the Liang's ring machine for core hidden ring cleaning. Hope it can help you, dear <>

Dear, do you have any other questions that I need to answer for you? <>
