While operating a car, some car enthusiasts are faced with the same important question, namely: how to remove the box on a VAZ 2114 or on another car of this AvtoVAZ line. The VAZ 2114 gearbox is the same as on the VAZ G8. The only difference is that the VAZ 2108 does not have a dipstick, and it accelerates faster.
The gearbox may need to be removed in a variety of cases, for example, in order to replace the clutch or something in its system, as well as to repair the gearbox itself.

CONSTRUCTION FEATURES
Structurally, the gearbox device is divided into 3 main parts: gearbox housing, rear cover and clutch housing. The internals of the device can be divided into two groups - the main pair and the differential with gear ratios.
The main pair, also known as the drive shaft of the gearbox, performs the function of reducing the speed transmitted from the engine to the crankshaft. The VAZ 2114 GP gearbox reduces engine speed by almost four times (gear ratio – 3.7).
Manipulations with the main pair, aimed at changing the gear ratio, allow you to change the length of the gears, which makes it possible to influence the acceleration and maximum speed of the fourteenth. However, it is not recommended to interfere with the operation of the box without proper qualifications - you can do irreparable things.
The VAZ 2114 gearbox that comes as standard has the following gear ratios:
- First speed – 3.636;
- Second speed – 1.95;
- Third speed – 1.357;
- Fourth speed – 0.941;
- Fifth speed – 0.784;
- Reverse – 3.53.
As evidenced by the reviews of the owners of the fourteenth, the standard gearbox is not the ideal of engineering thinking - the first speed is too short, the second, on the contrary, is long. Poorly selected gear ratios cause a serious loss of vehicle dynamics during acceleration when switching gears from 1 to 2.
The cost of a new gearbox for a VAZ 2114 is about 16 thousand rubles; used gearboxes can be found at prices ranging from 4 to 10 thousand, their price varies greatly depending on the condition.
Transmission device diagram
The gearbox mechanism is a system of parts that has an independent structure and characteristic features determined by the model. Before you begin repairing the gearbox, you must familiarize yourself with the diagram of the transmission mechanism in the operating manual. The diagram contains the names of the parts and the structure of the relationship.
Transmission device: 1 - input shaft; 2 - secondary shaft; 3 — rod for shifting the third and fourth gears; 4 — fork for shifting third and fourth gears; 5 — differential; 6 — fork for switching first and second gears; 7 — fork rod for shifting first and second gears; 8 — gear shift rod; 9 — fifth gear shift fork rod; 10 — gear shift mechanism; 11 — reverse intermediate gear; 12 — clutch housing
Knowledge of the structure of the structure reduces the time spent on identifying mounting fasteners and dismantling components.
POSSIBLE FAULTS
Despite the imperfect operation, the VAZ 2114 gearbox, when used correctly, is distinguished by good endurance and durability. If you do not hesitate to prevent and promptly eliminate breakdowns, repairing it is not expensive.
Let's consider the main gearbox malfunctions that the owner of the fourteenth may encounter:
- Lack of speed fixation when switching. If the speeds are out of whack, the cause is most likely worn teeth on the gears and clutch. Accelerated wear of these parts is caused by incorrect gear shifting and non-compliance with the speed limit. The problem is resolved by replacing the gears.
- The gear shift lever is tight. The reasons are mechanical damage to the teeth of the lever fixing on the hinge or wear of the reaction rod; it’s also a good idea to check the integrity of the plastic parts of the gearbox drive;
- The VAZ 2114 gearbox is humming. Most often, the gearbox is humming in neutral gear. First of all, you need to check and, if necessary, add oil (in general, the box may hum due to the use of low-quality lubricants). If the oil is normal, the problem is wear of the bearing on the input shaft, which can only be determined through diagnostics or by disassembling the gearbox;
- Crunching sound when changing speed. Here it is necessary to change the worn out synchronizer, and it must be changed immediately after the problem has been discovered, because if you tighten it, the gear unit will completely fly off;
- Knock. The gearbox on a VAZ 2114 can knock both under load and without it, and in any gear. The cause of the knocking noise is a damaged drive gear of the problematic transmission.
One of the key factors for the trouble-free operation of gearbox number fourteen is the use of high-quality lubricants. The most suitable option is GL-4 mineral oil. It is not cheap, but it does its job at 5+; when using mineral oil, VAZ gearbox repairs are usually required extremely rarely.
Most VAZ 2114 owners agree that the best gearbox oil is 75W90. It is distinguished by greater fluidity than typical gearbox oils, due to which the lubricant better gets into those places of the gearbox, the lubrication of which is provided exclusively by splashing. Good options for 75W90 are Hypoid-Getriebeoil TDL and Liqui Moly Vollsynthetisches Getriebeoil (GL-5).
Checking the oil level should be carried out every three weeks. In the gearbox, the fourteenth gear is placed vertically, the topmost is the fifth, it is the one that is most susceptible to failure due to lack of lubrication, so it is always necessary to fill in oil to the maximum mark, and best of all - 200-250 ml. more than the required norm.

How to remove the gearbox on a VAZ 2114
The best mode of engine operation, when the VAZ 2114 moves according to different criteria, is supported by the gearbox. This device is capable of changing the torque transmitted from the engine to the drive wheels of the vehicle during startup or acceleration.
In particular, the box converts rotational force into translational motion.
VAZ 2114 transmitting device
The main working element of the VAZ 2114 gearbox is the gearbox (gearbox). It consists of 3 main parts:
The VAZ 2114 body box consists of:
The internal structure of the checkpoint includes:
The main pair is the main transmission, which is the main shaft of the VAZ 2114 transmission. The main task of the main pair is to reduce the number of revolutions transmitted from the engine. The main pair reduces the speed by four times, that is, if the engine speed is 4 thousand, then for the main pair this figure is 1 thousand.
Default base pair number. 3.7. By changing the base pair, you can simply change the dynamic properties of the car. The length of the gears will depend on the size of the main pair, as well as characteristics such as acceleration and maximum speed.
The VAZ 2114 gearbox is synchronized and has 5 steps. This is due to differential and final drive. The input shaft is a block of gears of the first, second, third, fourth gears. The 5th gearbox has been installed.
The secondary shaft contains all the drive gears. It connects to the main gear of the final drive. The box control unit consists of:
Traction and ball bearing
· Mechanism for selecting speed modes and switching them
The main component of the transmission is high quality oil
It's no secret that the VAZ 2114 car is not meticulous technology. And she needs proper and high-quality care, especially when it comes to the box. It is very important to choose high-quality oil that will ensure uninterrupted, harmonious and accurate operation of all parts and components of the box.
For a VAZ 2114 car, oil of category GL.4 is suitable. The best option. mineral lubricant. But the price of such oil is high. In this case, you should pay attention to synthetic and semi-synthetic oil options.
Synthetic oil. the best option. It has excellent qualities, does not freeze in severe frosts and does not heat up, even if it is 30 degrees outside. The only drawback of synthetic oil is the rapid clogging of seals. But if you look closely, nothing bad will happen.
Get yourself diagnosed and serviced
Owners of a VAZ 2114 car often encounter problems and breakdowns of the box. Common reasons affecting the performance of the VAZ 2114 gearbox include:
1. Noise at the checkpoint.
Worn gears or bearings and lack of oil levels may be a must.
Obstacle: Replace worn parts. Add oil. Replace gaskets and seals if necessary.
2. Difficulty shifting gears.
The gear shift rod may be deformed. The screws that secure the pivot or shift lever may become loose. The gearshift actuator may also be incorrectly adjusted. The plastic parts of the drive may not work properly.
The solution is to straighten or completely change the rod, tighten the screws, adjust the drive, replace faulty parts.
3. Spontaneous deactivation of gears.
This can be caused by damage or wear to the synchronizer tooth end on gears and clutches. A prerequisite may be incorrect adjustment of the drive or incorrect installation of the rod protective cover, which prevents the gears from engaging.
Solution: Replace worn parts, repair drive, or adjust cover.
Such a breakdown may be caused by wear of the input shaft seals or the speedometer drive roller seals. Worn joints of the body with the same angular velocity also affect the situation.

A more common cause of transmission failure is a lack of oil level in the system. Such an event can lead to premature wear of gearbox parts and subsequent costly repairs.
The car owner should check the oil level more than 3 times a week. This is the only way to detect oil leaks early and clean them immediately.
REMOVAL AND REPAIR
Almost any DIY repair of a VAZ 2114 gearbox - installing new bearings, clutch or gears - involves removing it. To do this, you will need screwdrivers, a set of wrenches, WD-40 and hanging equipment to lift the unit.
Let's figure out how to remove the gearbox of the fourteenth:
- We drive the car onto an overpass or into a garage with a pit. First of all, we disconnect and remove the battery, then drain the oil from the gearbox and remove the starter. To do this, you need to disconnect the power wires from it, remove the protective jacket, unscrew the two fixing nuts from the bottom (from the pit) and one from the top of the starter;
- Now you need to remove the connecting cable from the clutch release fork and remove it from the bracket on the gearbox;
- Disconnect the wiring to the speed sensor. The wire block is secured by a spring, which must be compressed to disconnect the connection;
- We climb under the fourteenth and disconnect the wiring from the reverse sensor;
- We tighten the bolts with which the jet thrust bracket is attached to the unit body;
- We remove jet thrust. To do this, you need to loosen the clamp connected to the rod and move it back, which will make it possible to remove it from the hinge;
- Now you need to dismantle the wheel drives: remove the left one completely, and simply unscrew the right one, move it to the side and hang it on the car body;
- We unscrew the bolts from the ball joint (left) that secure it to the steering knuckle;
- We dismantle the gearbox mount to the engine on the lower right side; to do this you need to remove the supporting brackets from the stud;
- Remove the clutch housing cover (it is secured with 3 bolts);
- Unscrew the bolt on the lower left gearbox mount;
- Unscrew the nuts that secure the left and rear engine mount;
- Now we remove the fixing bolts with which the gearbox is attached to the rear engine support. We dismantle the support itself;
- Using a screwdriver as a lever, insert it into the hole between the engine cylinder block and the clutch housing, and move the gearbox off the guides as far back as possible. The rear part of the box body should pass on top of the suspension extension, and the input shaft will be disconnected from the clutch, after which the unit can be removed from under the car.
Now you know how to remove the VAZ 2114 gearbox. Good luck with your driving without any breakdowns!
