By the time of the next technical inspection of the car, the owner should be fully armed and familiarize himself in advance with the range of oils suitable for the VAZ-2114 gearbox. You should be especially careful about the replacement procedure at high mileage, because then the car requires increased attention.
How much oil should I add to the VAZ-2114 gearbox? According to the manufacturer, the volume of the VAZ-2114 gearbox is 3.5 liters . Due to the fact that when changing the oil, a certain amount of transmission fluid remains on the walls, the amount of oil will be approximately 3.3 liters .
Recommended oil types
Lubricating fluids of the GL4 . Synthetic, semi-synthetic and mineral types of oils are suitable for the VAZ-2114 Most often, car enthusiasts choose the following options:
- 75w90
This type of oil is synthetic . It is ideal for vehicle use in low temperature conditions and has excellent lubricating properties. It is this type of transmission fluid that is recommended by the factory for the VAZ-2114. The disadvantage is the increased noise level compared to semi-synthetic analogues.
- 85w90
Representative of the semi-synthetic type. It has a lower cost than synthetic oils and is well suited for high mileage vehicles.
- 80w90
This is a mineral lubricant for gearboxes, which many car enthusiasts consider the best choice for the VAZ-2114 gearbox . Disadvantages include high price and instability to low temperatures due to increased viscosity.
Keep in mind that when replacing lubricating fluid, you cannot mix different oils; this can lead to costly repairs.
What's the result?
As you can see, before choosing oil for the VAZ 2115-2114 gearbox, as well as other models, it is necessary to separately take into account a number of features. First of all, on the VAZ 2114 the gearbox is considered noisy, especially when driving in 5th gear.
We also recommend reading the article on how to change the oil in a Lada Granta automatic transmission. From this article you will learn how to change the Grant automatic transmission oil, as well as what needs to be taken into account as part of this procedure.
For this reason, some owners try to solve the problem with oil, pouring thick mineral water into the box. On the one hand, the noise level actually decreases, but on the other hand, in winter, the wear of the “cold” gearbox also increases, the gears are difficult to engage before the transmission warms up, etc.
In practice, the “golden mean” is 75W90 transmission oil. If we take into account the above-mentioned features of selecting such an oil, then we can fully count on acceptable operation of the box in any conditions without loss of unit life.
Video on the topic of choice:
Among the 75w90 group oils, the following options are especially popular:
- Shell Getribeoil EP
- Eneos
- Castrol Syntrans Transaxle
These lubricants are somewhat more expensive than other oils, but their composition is significantly superior to their analogues.
The best choice in the 85w90 would be the following brands:
- MOBIL Mobilube LS
- JB GERMAN OIL GL4
- Gazpromneft SUPER
For type 80w90 the following oils can be distinguished:
- Motul MOTUL HD
- LIQUI MOLY Marine Gear Oil
- Castrol Manual EP
Liquids from these manufacturers are considered the best in terms of price-quality ratio.
What does your car manufacturer recommend?
Of course, the car manufacturer will not indicate the name of the manufacturer of technical fluids in the specification. VAZ gearbox oil is produced under various brands; a reference to a specific name is nothing more than advertising.
AvtoVAZ recommends Lukoil TM 4-12, but this is just a recommendation, not a prescription . If the instructions give preference to a certain brand, others can sue, and they will be right. Normal operation of the car depends only on the properties of the oil, and not on the logo on the packaging.
You can refer to the experience of VAZ 2114 owners. Judging by the reviews, the following brands are used:
- Lada Trans KP;
- Lukoil TM 4-12;
- New Trans KP;
- Nordix Supertrans RHS;
- Slavneft TM-4;
- Castrol 75w90;
- Shell Getribeoil EP 75w90;
- TNK 75w90.
The manufacturer is also not against the listed oils, at least these are the brands offered in official service centers, and no one worries about warranty claims.
The main indicator is the viscosity of the oil. For moderate climates, the value 80W90 is suitable - these are the parameters recommended by the car manufacturer. With such a transmission you can safely drive both in the summer heat and in mild frosts (down to -20°C).
This is a universal approach, just like for all-season tires on wheels. But for northern regions it is better to use the 75W90 formula. During severe frosts, you can start the car even with a dead battery. And heat over +30°C is unlikely in such an area.
When filling in new transmission lubricant, you must be aware that you will use the fluid for several years without changing the lubricant when switching from summer to winter operation. Therefore, the recommendations of the car plant are one thing, but actual operating conditions are completely different.
Another limitation of the plant is the API quality standard. Transmission fluid must be marked at least GL-4, or TM-4 according to Russian qualifications.
Synthetics
When choosing synthetic gearbox oil, the motorist needs to pay attention to the temperature conditions for which the purchased product is designed. These are the last two digits in the encoding.
The main advantages of synthetic oil are that it prevents the formation of toxins, reduces power loss when the engine warms up, and ensures efficient operation of the car in the long term. Buy synthetic lubricants only from trusted sellers, since by saving a few hundred rubles you can run into a fake and spend much more money on eliminating the damage caused. The best synthetic oil for the VAZ-2114 is Castrol Edge Titanium FST.
Oil change intervals
According to the manufacturer's regulations, the oil in the LADA Priora gearbox must be changed every 75 thousand kilometers, or after 5 years of operation. But this replacement interval can be used as a guide if the machine is operated without special loads on good roads. In fact, the oil is changed every 50-60 thousand kilometers, and with an aggressive driving style, frequent traffic jams and other difficult conditions, the transmission fluid should be changed every 35-40 thousand kilometers.
The fact that it is time to update the oil in the box can be determined by the following signs:
- Oil deposits
- The smell of burning
- Difficulty shifting gears
- Knockout of the gearbox lever when the gear is engaged
- Increased noise during unit operation
- Increased vibrations of the gearshift lever
All this indicates that the transmission fluid has lost its properties or is of poor quality.
How to change the gearbox oil yourself
To do this, you need to arm yourself with a container for draining used oil, keys “8” and “17” and perform the following steps:
- First, it is important to determine the oil level in the gearbox . To do this you need to find a dipstick. Be sure to remove oil traces using a lint-free rag. Then return the dipstick to its original position. After a couple of minutes, remove it again. Find the maximum and minimum marks on the dipstick, and then compare with where the oil mark is located. This way you will find out how much oil is missing.
- Before changing the oil, it is necessary to warm it up. To do this you will need to drive a little. This is necessary so that the old oil flows out faster. After a short trip, drive your car onto the overpass. Remove the protection and remove the dipstick. Then you need to carefully unscrew the drain plug and immediately place a container for used oil. Before moving to the next step, make sure that all transmission fluid has drained from the transmission. It can take some time. Tighten the drain plug.
All that remains is to fill in new oil. Insert the funnel and hose into the hole from which you removed the dipstick. Fill with 3.3 liters of the selected lubricant. Be sure to check the level with a dipstick.
Types of gearboxes in LADA Priora
LADA Priora cars were equipped with a mechanical and robotic gearbox.
A manual transmission called VAZ-2170 was used in cars from 2007 to 2015. After 2014, it remained only on 8-valve cars. The transmission was a modernized version of the VAZ-2110 gearbox. This is a 5-speed unit combined with a final drive and differential.
The unit was not highly reliable. Here the gears, bearings and synchronizers wore out quite quickly, and many oil seals began to leak oil at low mileage of the car. In addition, the gear shifts in this box are unclear, the gearshift lever is poorly fixed, and the transmission control drive and clutch require constant adjustment.
Starting from 2015, LADA Priora with 16-valve engines was equipped with a new gearbox called VAZ-2180. It is a deeply modernized version of the VAZ-2112 gearbox. The control mechanism of the new unit is now installed on top, and therefore does not depend on the temperature of the oil, the volume of which has been reduced by 1/3. Rigid shift rods have been replaced with a cable drive, which has reduced noise and vibration of the gearbox. The new box has overcome almost all the diseases of the previous version.
Among the minuses, one can note a crunch when changing gears, oil leaks, and failure to engage gears after a mileage of 50 thousand km. Despite the installation of a cable drive, noise during operation of the transmission and vibration of the lever still remained.
A robotic gearbox called VAZ-2182 AMT was also installed on Prioras with 16-valve units. Structurally, this is the same VAZ-2180 gearbox, where instead of a cable drive, actuators from the German company ZF are responsible for shifting gears.
The manual transmission turned out to be controversial. On the one hand, it has become easier to drive the car, since the clutch pedal has disappeared, but on the other hand, the operation of the unit is unclear and illogical. This was especially true during heavy traffic and traffic jams. AMT problems include transmission overheating, oil leaks, electrical problems and vibration of the gearbox selector.
What is the difference between GL-4 and GL-5 75W-90 oils?
As already mentioned just above, the purpose of TM GL-4 (according to GOST 17479.2–85) is for operation in transmissions with bevel and hypoid gears , operating at contact stresses up to 3000 MPa and oil temperatures up to 150 °C. By and large, these are gearboxes of front-wheel drive cars. API GL-5 - ensures reliable operation of hypoid gears operating with shock loads at stresses above 3000 MPa. It is used in gearboxes with hypoid bevel gears and for final drives with cardan drives in drive axles (with limited slip differential LSD). This transmission fluid provides better protection under high load and pressure conditions.
Errors when choosing TM 75W90 and the difference between GL 4 and GL 5.
The key feature is that 75W90 API GL-4 oils contain two times less sulfur-phosphorus additives than similar ones, only of a higher class. Such additives create a special protective coating on parts that prevents wear, but this substance is even stronger than the surface of parts made of copper or other soft alloys. Therefore, using TMs for purposes other than their intended purpose threatens to wear out the surface of an element made of soft metal. So, in those gearboxes where it is necessary to use 75W90 GL-4, and GL-5 is poured, there is a rapid appearance of copper shavings, since the synchronizers are made of copper, and the sulfur-phosphorus additive kills them.
The best choice for domestic classics
Mechanical gearboxes, which are installed on domestic cars, have several irrefutable advantages. Firstly, this is an extremely reliable unit that does not require expensive maintenance. Even if there is a need for major repairs, it will be relatively inexpensive.
However, regular maintenance should not be neglected. It is advisable to purchase lubricant from trusted places and not skimp. The replacement interval is 3-4 years or 150 thousand kilometers, whichever comes first. This is not motor oil that needs to be changed every 8-10 thousand miles. An excellent choice would be Castrol or Motul. From budget and high-quality, I can recommend.
Checkpoint "Niva Chevrolet"
The domestic SUV is extremely passable and reliable, but requires careful maintenance. In particular, this applies to a manual transmission. It is allowed to use oil of group GL-4/GL-5 or GL-5. For normal operation of the unit, oils with the following viscosity are best suited: SAE 75W-90, 80W-85 and 80W-90. If you comply with all the above requirements, the box will work much quieter and longer.
Among motorists, a rating of proven transmission oils has long been formed. It is best to pay attention to them. If you are asking the question: “Which gear oil is best for the Chevrolet Niva?”, then you should definitely try Eneos 80W90 Gear GL5. This lubricant showed excellent performance at low temperatures, maintaining acceptable fluidity. True, it is sold only in 4-liter cans, which is not very convenient. Also, many motorists advise trying Castrol Syntrax Universal Plus. This is an expensive transmission that provides impeccable softness of gear shifting with a long replacement interval - 300 thousand kilometers.
Gear oil group
In order to understand in more detail which gear oil is best for the VAZ-2107, it is necessary to consider several important characteristics of the lubricant. In particular, this applies to the group of lubricant compositions, which are:
- GL-4 – oils with a large number of additives. Excellent for use in boxes whose operating modes do not require high torques. There are also oils that, on the contrary, are more suitable for high torques;
- GL-5 is a group of oils intended for hypoid gears. If the car is equipped with a gearbox with a hypoid gear, then only GL-5 can be filled into the gearbox.
It is extremely important to choose the right oil group. This will ensure long-term operation of the gearbox even in difficult conditions. At the same time, do not forget about regular replacement, but we will talk about this a little later.
