The gearbox linkage is a part of a multi-lever unit that acts as a connecting link between the gearbox lever and the rod. Note that in the Chevrolet Niva, such an element as the rocker is located at the bottom of the car body near the driveshaft. This component is susceptible to the appearance of moisture and contamination, and this, after some time, deteriorates the quality of lubrication of rotating parts. Consequently, the components wear out, causing various problems.
In relation to other components of the transmission, the rocker, also known as the gearbox control drive rod, is considered a relatively simple device in structure. However, for correct operation, the condition of the scenes should be given due attention. That is, it is important to do repairs or adjust traction on the Chevrolet Niva in due time. Any car owner wants no force majeure to occur during the movement, and therefore the condition of the scenes must be monitored.
On most vehicles, the rocker looks like a fairly durable device that is quite capable of being used for about a hundred kilometers without replacement. At the same time, drivers are not insured against damage to this unit. How can you identify the need to repair the rocker on your Chevrolet Niva? This can be determined for the following reasons:
- The gearbox lever clearance has increased significantly;
- there are problems with gear shifting (the lever may float);
- Reverse gear does not engage;
- adjusting the backstage became impossible.
If the gears work poorly or the wrong one works at all, it makes sense to adjust the mechanism. Naturally, such a fact is relevant only when the position of the drive is visually assessed as working. When the connecting parts of the device’s hinges operate with significant play, then it is advisable to replace the component on the Chevrolet Niva.
When studying a Chevrolet SUV, which we know as a relative of the VAZ, many do not understand what a rocker is and where to look for it. By the way, in Chevrolet there are 2 such devices. One rocker is designed to change gears, while the other switches transfer case modes.
Note that the rocker, equipped on a Chevrolet Niva SUV, has a powerful operating resource. However, this reserve directly depends on the style of driving the machine.
Consequently, sometimes car owners notice malfunctions in the operation of the gearbox, manifested in the following:
- when engaging 1st gear there is a spontaneous shift to reverse;
- when switching on, 5th speed disappears;
- activating reverse gear instead of selecting forward 5 gears.
Do-it-yourself Chevrolet rocker adjustment: instructions
To set up the scenes you need to perform a number of actions.
- 1st gear does not engage at the gearbox. To turn it on, you need to start the engine, moving the gearbox lever until the car starts moving. Next, turn off the engine while 1st gear is engaged. You need to place shoes or wheel chocks under the tires, not forgetting the parking brake.
- Next, you will need to lower yourself into the hole to unscrew the clamp bolt of the rocker itself.
- Now you need to find the plastic traction lock in the Chevrolet Niva interior and move it to the far left position.
- Next, you need to once again lower yourself into the inspection ditch to tighten the loosened clamp bolt.
So, the gearbox traction adjustment can be considered complete. Now it’s worth checking the functionality of the part. It happens that this process does not help, there is no result, and removal and, therefore, complete repair of the component is required.
Why does the reverse gear not engage on the Niva Chevrolet?
Experts note that during the operation of a Chevrolet Niva, something happens that it stops engaging in reverse gear. This happens due to the fact that the car has a worn-out rocker, which plays an important role when changing gears.
The design of the rocker and its purpose on the Niva Chevrolet
Backstage location.
In technical language, the word “link” means the gearbox drive rod. This is a complex mechanism and is designed to connect the gearshift lever in the cabin and the rod of the gearbox itself . In the interior of the Niva Chevrolet there is a backstage located near the gearshift lever, and therefore it is quite easy to find it.
Mechanism problems
After the procedure for adjusting the traction of the Niva Chevrolet gearbox, faults continue to appear? Pay attention to them:
- free movement of the transmission lever increases;
- speeds do not change;
- difficult gear shift;
- switching on another gear or there is no possibility of switching gears.
When these problems are identified, there is a need for significant action, expressed in the repair or replacement of the scenes. However, to actually carry out such activities, the mechanism must be removed.
Purpose and design of the gearbox gate
The rocker is technically referred to as a gearbox drive rod and is a complex mechanism designed to connect the transmission shift lever with the gearbox rod.
On Chevrolet Niva SUVs, the rocker is located in the cabin near the lever itself, as in many models of Russian cars. Finding it is not difficult if you know what a gearbox is. The slide is located near the transmission shift lever and has the appearance shown in the photo below.

On older models of vehicles from the Russian automobile industry, the location of the rocker was located under the bottom of the car, but this reduced, first of all, the service life of the product, which affected efficiency.
Backstage adjustment
The link on Chevrolet Niva SUVs has a long service life, equal to over 100 thousand kilometers. But this resource depends, first of all, on the integrity of driving, so sometimes drivers may notice failures in the operation of the gearbox, such as:
- When you try to engage first gear, it switches to reverse;
- Fifth speed disappears when it is turned on;
- Reverse gear is engaged when forward five gears are selected.
This indicates a malfunction of the drive rod, but you should not rush to remove the gearbox and repair it, as you can try to adjust the product. Although adjustment is a rather difficult task, it is easier and cheaper than replacing a box or a link.
Location of the rocker clamp bolt
Adjusting the backstage includes the following steps:
- The gearbox engages first gear. To turn it on, you can start the engine and move the gearbox lever until the car starts moving. Afterwards, the engine is turned off, the first gear remains on, and shoes are placed under the wheels. Don't forget the handbrake.
- Lower into the overpass and loosen the bolt of the rocker clamp.
- Inside the car we find a plastic traction lock and move it to the extreme left position until it stops.
- After this, you should go down into the pit again, but tighten the loosened clamp bolt.
Transmission linkage: removal
The rocker on a Niva Chevrolet SUV is removed in the following order:
- Open the hood of the car and find the clutch tip of the lever, as well as the gearbox linkage. The rod has a turnbuckle with a protective cover that will need to be removed.
- In the Shnivy interior, remove the trim of the gearbox lever using a screwdriver. You should be careful not to damage the latches.
- Turn the cover the other way, and then cut the fastening clamp. Next you need to remove the cover from the lever.
- Remove the front of the floor tunnel lining.
- Unfasten the fasteners from the lever and remove the axle.
- Remove the shift lever by moving it up, and the remaining rubber cuff must be returned inside the removed lever.
- Remove the lever housing fixing bolts and remove the rocker.
- Remove the rod (rubber sleeve) from the shaft.
- Observe the rod for damage or defects. This way it will be possible to determine whether the backstage requires repair or replacement.
Replacement should be carried out if there is a gap in the hinges or serious wear of the play under the axis of the speed shift knob. If the boot is damaged, you will have to replace it with a new one. So, you need to cut off the worn boot and remove it, installing a new one in its place. You should first lubricate the internal parts with Litol.
In other cases, it’s time to repair the backstage. You will need to buy a repair kit in advance, which contains plastic seals. Before installing the seals, you need to lubricate them with Litol-24. After completing the repair, all that remains is to assemble all the parts in the reverse order of removal. Upon completion of assembly, it is worth remembering the new clamp that was cut when removing the cover.
How to Remove the Chevrolet Niva Gear Lever
Backstage of the Niva Chevrolet jeep
Continuing the study of the Russian Niva Chevrolet jeep, which is a relative of the VAZ family of cars, we will pay attention to such a detail as the backstage.
What is it anyway and where is it located? Surely, every driver today has often heard during training at a driving school about how the instructor “swears” at the obsolete stage when he changes gear.
Yes, indeed, the rocker is a part of the box that performs an important function, but in the Chevrolet Niva there are two such devices: one rocker is used to change gears, and the other is used to switch transfer case modes. But this is actually what this material will say.
Purpose and design of the gearbox gate
The rocker is technically called a box drive rod and is an all-encompassing mechanism designed to connect the box shift lever with the box rod.
On Chevrolet Niva jeeps, the rocker is located in the cabin near the lever itself, as in almost all models of Russian cars. Finding it is not difficult if you know what a gearbox is. The slide is located near the transmission shift lever and has the appearance shown in the photo below.

Chevrolet Niva gearbox lever play
Backlash appeared after 5 years of operation and 100,000 km...
At this point, the gearbox thrust adjustment is completed, and you can check its performance. If the adjustment does not help, then the product will need to be removed and repaired.
Mechanism malfunctions
If, after the procedure for regulating the traction of the gearbox of a Niva Chevrolet, further malfunctions are identified, which manifest themselves in the form of:
- the free play of the transmission lever increases;
- problems with gear shifting;
- speeds turn on slowly;
- Engaging in the wrong gear or being unable to switch gears.
If such problems are identified, the need for more serious repair or replacement of the scenes arises. But to be able to carry out such actions, the device must be removed.
Removing the gearbox linkage
You can remove the slide in the following sequence:
- Having opened the hood of the Chevrolet Niva, you need to find the connection between the tip of the lever and the gear shift rod. The rod has a turnbuckle and a protective cover that need to be removed.
- In the interior of a Chevrolet Niva car, the gearshift lever trim is removed using a screwdriver.
But be careful not to damage the fasteners. - The cover must be turned in the opposite direction, and then the fastening clamp must be cut. Next, remove the cover from the lever.
- The front of the floor tunnel lining is removed.
- The latch is unfastened from the lever and the axle is removed.
- The shift lever is removed by holding it up. The remaining rubber cuff must be returned inside the removed lever.
- The bolts securing the lever housing are removed and the rocker is removed.
- You will need to remove the rubber bushing (rod) from the shaft.
- Next, you need to inspect the rod for defects to determine what is required: repair or replacement of the product.
Replacement is made if there is play in the hinges or severe wear of the hole for the gearshift handle axis. Also, if there is damage to the boot, it must be replaced with a new one. To do this, cut off the old boot and remove it, and install a new one in its place, having previously lubricated the internal parts with Litol.
In all other situations, the backstage can be repaired. To do this, you will need to purchase a special repair kit, which includes plastic seals.
Before installing the seals, they will need to be lubricated with Litol 24. This completes the repair of the product; all that remains is to assemble all the parts in the reverse order of removal.
Once assembly is complete, don't forget about the new clamp that had to be cut when removing the cover.
And a few words about the transfer case rocker
The transfer case performs similar functions to a boxed product, only the gear shift lever is not used as often as the transmission.
From this it follows that the transfer case rod has a much longer service life.
If similar problems are noticed as in the gearbox, then it is worth replacing the transfer case, since its mechanism does not allow repair or replacement.
Based on all that has been said, the gearbox and transfer case are important elements of the Chevrolet Niva, without which it is impossible to engage gears.
Do you still think that diagnosing a car is difficult?
