Adjusting the gearshift cables of the Lada Granta

Those. Most solutions do not remove the vibration itself from the fork, but leave it within the play of the cables. And the vibration occurs only along one cable - the one that presses on the fork, so the lever trembles in the longitudinal direction. Those. vibration source: aluminum 3/4 gear fork.

The shaking does not occur at all speeds (from new on cold oil it was from 2500-3000), on hot oil from 3500 during acceleration. Now the trembling is only felt by the hand on the lever, if it is pressed to the boundary point of the 3rd gear, but a little back and everything is quiet (it no longer makes noise).

IMHO, all solutions to dampening noise in the handle mechanism are other than simply “muffling the problem itself.”

Another option is that in 3rd gear the engine bends onto the mount, which adds a cable tension effect

- i.e. There is vibration only during acceleration. Initially, I simply pulled the gearbox lever slightly towards myself during acceleration (much like on an old gearbox - like the VOLGA, when the lever presses with its weight on the fork, it wobbles), with us it presses but through a cable.

By the 10,000th mileage, the vibration went away on its own (minuscule remained) - i.e. The pressure of the fork to the coupling is minimal there (probably the fork has gotten used to it), with all the clamps in the same position. Due to manufacturing tolerances, some people have a larger clamp and may not wear in for a long time.

The treatment option was to weaken the clamp spring by placing a 2mm thick washer under it (pos. No. 9) in the picture. But I couldn’t unscrew it with a regular key (24). The second post-retainer from the top presses on the plate (I took the picture a page earlier) - of a tricky shape, and this plate turns the rocker shaft, on which the shift cable sits - i.e. Due to this clamp, the mechanism is fixed at the desired point even without the gearbox itself, and in fact this mechanism continues to put pressure on the 3/4 gear fork. The only difference is that when accelerating to 3rd, the engine on the cushions turns out and the cable tightens even more, but in 4th, on the contrary, it loosens.

Added after 8 minutes As an option, someone moves the cables and sometimes helps. You just need to take into account that the position of the cables when the car is turned off is not the same as it will be during acceleration, and taking into account this correction, you can add play (the cable should not be tight when the third one is on) and as a result, weak vibration will not go beyond the rocker/cable connection under the hood - it is really weak and has a small amplitude. But when it hits the lever, its large shoulder, like a pendulum, swings a little more.

Of the many options, I would choose the option with a washer (but the vibration itself began to go away, and I had already bought a washer, I didn’t find the time and a high head for 24, the low one doesn’t fit) And I wanted a short-throw link (after loosening the spring, I think it would be just right was)

Added after 6 minutes And to check whether there will be vibration on the 3rd without unscrewing the motor - just put it on bricks and try to spin the wheels as usual - I didn’t have any vibration at all - i.e. By turning on the third, pulling the cable, we “ate” the backlash and any bend in the motor will create a force on the rocker.

PS: OD has not yet removed it under warranty - but they did change the cables. I personally don’t understand at all how they wanted to remove it by changing the cables if it comes from the wings.

Lada Granta gearbox with cable drive

When AvtoVAZ decided to install modernized transmission units on its progressive Lada Granta and Kalina models, most car enthusiasts looked at these products of the domestic automobile industry in a new way.

The updated transmission, a cable-driven gearbox, has gotten rid of the vibration that previously occurred during driving. At the heart of the design of the switching unit, instead of the previously familiar rods with the scenes, there are now connecting cables. This made it possible to eliminate the negative impact on the vibration stability of the unit.

Operational and design features

Among the main innovations of such a development as a cable-driven gearbox is a reduction in the volume of oil used in the box. Previously, the manufacturer assumed the use of mineral fluid in a volume of 3 liters, but now the unit requires semi-synthetic fluid with the amount reduced to 2.2 liters.

Many Lada Granta owners are concerned about the question that has arisen: what type of oil should they choose when replacing a progressive gearbox to ensure its normal functionality? The manufacturer continually recommends using fluids with a viscosity parameter of “75W-85” in accordance with the “GL-4” specification.

A distinctive feature of the new cable-driven gearbox from its ancestor (VAZ-2108) is the modernized switching circuit. This confirms the fact that the fifth speed is not located to the left of the first stage, but opposite the 5th gear. This design has managed to acquire serious popularity among Grant owners. It also allows you to eliminate the moment of accidental engagement of reverse gear when moving forward.

Also among the advantages of the new transmission of the Lada Grant are the following points:

• the ability to operate in severe frost (down to minus 42 degrees) while ensuring free manipulation of the lever;
• availability of the procedure for removing the switching unit without completely dismantling the transmission unit;
• quick gear changes with a minimum of effort;
• increased reliability and protection of 1st and 2nd gears due to the use of cone synchronizers;
• the fact that the intermediate segments of the synchronizers were coated with a special composition, which made it possible to improve the quality performance of the unit.

Procedure for removing a manual transmission

Required materials and tools:

• set of car keys, sockets, ratchet;
• rags;
• additional lighting;
• jack;
• graphite lubricant;
• plastic container for draining waste;
• transmission oil.

Step-by-step instructions for replacing a manual transmission

1. We install the machine within the perimeter of the repair area: on an inspection hole, on a road overpass.
2. We remove the terminals from the battery, preventing a short circuit in the circuit.

1. We dismantle the air filter and the plastic air filter housing.

1. We unscrew the fastening nuts, remove the power terminals, and dismantle the starter.

1. We unscrew the mudguards and the oil pan protection (if any).

1. Remove the block with wires from the reverse activation sensor.

1. Disconnect the contacts from the speed sensor.

1. We twist the drain plug and drain the waste from the manual transmission.

1. Disconnect the clutch cable, lever fork, and bracket from the gearbox housing.

Lada Granta with automatic transmission

The Russian automobile industry has begun to seriously work on its mistakes, and the new Lada Granta with an automatic transmission serves as a striking example. Looking at the car body, equipment and interior, you can immediately understand that the car was manufactured by a Russian engineer for a Russian driver. The car is fully prepared for domestic roads, and almost every desire and need of the buyer is satisfied. Increased ground clearance, electric windows and a spacious trunk are ideal for the practical driver. Improved design and thoughtful shapes make the car not only practical, but also a beautiful means of transportation.

But still, the main advantage of the Lada Granta is the presence of an automatic transmission. The domestic car began to be equipped with an automatic transmission from the Japanese company Jatco. The four-speed transmission JF414E (AY-K3) from a subsidiary of Nissan is time-tested and has been serving Almera and March for a long time. Resistant to wear and aggressive driving style, the Japanese mechanism is ideal for both inexperienced beginners and experienced drivers. It is worth noting that the box has undergone minimal changes by Russian engineers, so there is no need to worry about the service life and safety of the unit. The box is time-tested, and its characteristics are not inferior to new models.

Adjusting the gearbox cable drive on the Lada Granta

Like every car mechanism, it is important to monitor the gearbox and correct any malfunction in a timely manner. In addition, you can adjust the working mechanism in order to improve the performance of the “sluggish” Lada engine. One of these upgrades is setting up a gearbox with a cable drive built into the Lada Granta. But before you tinker with a transmission element, it’s important to familiarize yourself with the consequences of tuning. It also doesn't hurt to check the warranty card. If the car's warranty has not yet expired, then it is better to hold off on setting it up, or contact a service center.

Consequences of gearbox modernization

Among the positive factors, we can note more accurate operation of the gear shift mechanism. If the setting is done correctly, vibration on the lever and extraneous noise will noticeably decrease. Fine-tuning will improve not only the accuracy of gear operation, but will also increase the reliability of the entire unit. But besides the positive properties of the gearbox modification purchased on a Lada Granta, there are also negative factors that you also need to become familiar with.

It is important to understand that any interference with the operation of well-functioning mechanisms may result in failure. As a result, you need to spend a considerable amount of money on car repairs. To independently debug a box from a domestic manufacturer, you need to have at least a little experience in car repair. If you adjust the cable on the Lada Granta machine incorrectly, the quality of switching will deteriorate significantly. Extraneous noise and vibration may appear, in the worst case, the transmission may jam. Incorrect settings will also lead to deterioration in overall technical performance.

Gearbox lever play on Priora, rocker. Causes

Initially, all Priors of the early years of production suffered from increased play on the gearshift lever and, as a result, slurred and uninformative shifting. A couple of years later, AvtoVAZ heeded the groans of the owners and replaced the initially defective universal joint with the same one from the Lada Kalina.

How much this helped is known to those who installed the Kalinovsky cardan on the Priora’s rocker with their own hands. It didn’t help, at least it didn’t radically solve the issue with the lever looseness. And it’s difficult to solve it, since the design of the backstage itself (even after restyling and modification) looks dubious.

What to change in the backstage if it doesn't work

The only option to somehow improve the situation is to carefully refine each connection in the backstage with your own hands, without allowing a single inaccuracy. To do this, we will have to buy a repair kit for repairing the scenes of either the Lada Grant or the Lada Kalina.

The difficulty is that the repair kit can be hidden under a whole bunch of catalog numbers. Here are some of them:

• 110-1703317 lining of the reverse locking bracket;
• 2170-1703219 gear lever axis;
• 2190-1703086 spring;
• 2110-1703198-01 retaining ring;
• 2170-1703371 support washer, 2 pcs;
• 21100-1703041 ball support;
• 2170-1703226 spacer bushings, 2 pcs.

Catalog numbers are given for the case when the repair kit is not on sale. The price of a repair kit is about 7-9 dollars, depending on the manufacturer and the greed of the seller.

How to change gears on a grant

Unlike a conventional gearbox, the cable-driven gearbox has received some improvements and upgrades.

VAZ-2181 gearbox with cable drive

In order to understand how everything works, let’s compare a standard gearbox labeled VAZ-2180 and the new VAZ-2181:

• To reduce the vibration generated by the traction drive gearbox, cables from the manufacturer Atsumitec were installed.
• To reduce the effort for shifting 1st and 2nd gears, the manufacturer installed multi-cone synchronizers.
• The clutch size has increased to 215 mm.
• Due to changes in the transmission design, the starter had to be positioned along the engine rather than the gearbox.
• To facilitate gear shifting, it was necessary to reduce the bevel angle of the synchronizer teeth from 125 degrees to 100.
• To eliminate oil leaks, the designers moved the gear selection mechanism to the top. But this nuance gave impetus to the development of a new switching scheme and design changes.
• The volume of lubricant poured has decreased from 3.3 liters to 2.2 liters.
• A selector plate is installed, which allows you to change gears more clearly.
• The transition from mineral oil to semi-synthetic oil has been completed.
• To prevent accidental reverse gear, a special lock was developed.

The main elements and components that go into the design of the new gearbox can be seen in the figures below:
