Options
According to the price lists with prices and configurations, the 5-speed manual Renault Arcana JR5 is combined only with the base 1.6 liter engine and front-wheel drive.
The all-wheel drive version of the 1.6 crossover is equipped with a 6-speed manual transmission TL8.
For the top 1.3 liter turbo, the CVT X-Tronic variator is exclusively designed. Some potential buyers see this as a drawback, believing that a version with a 150-horsepower engine and a stick would also be popular.
Gearbox malfunctions and methods for eliminating them
Any mechanism has a tensile strength, especially if it operates under variable loads. It is necessary to take into account the driver's driving style, which significantly affects the durability of the part. Summarizing the accumulated experience and analysis of breakdowns that occur during the operation of the car, gearbox faults can be grouped into several main groups: noise in the gearbox, difficulty engaging the gear and spontaneous shutdown of the transmission.
Noise and difficulty shifting gears
The main causes of noise in the gearbox include:
- low oil level;
- water entering the system;
- wear of bearings or gears.
To fix the problem, you should add or replace the oil in the gearbox, replace the bearings and gears with new ones.
Difficulty shifting gears can be caused by the following factors:
- faulty gearbox control rod;
- loosening of fastenings;
- deformation of control drive parts;
- wear of synchronization rings;
- incomplete disengagement of the clutch.
The listed faults can easily be eliminated by adjusting the clutch and replacing deformed and worn parts. It also helps to adjust the mechanisms in accordance with the regulations indicated in the car’s operating manual.
Spontaneous transmission shutdown
The reasons for spontaneous shutdown of the gearbox are usually:
- gear wear;
- damage occurs on the rubber supports of the box;
- wear of the synchronizer rings.
These faults can only be corrected by replacing them with new parts. Do-it-yourself transmission repair requires high qualifications and a set of special tools. Only a competent specialist can remove and disassemble this part correctly.
Mechanics Renault Arcana 1.6 l JR5
As a manual transmission, the Renault Arcana 1.6 with front-wheel drive has a JR5 gearbox with 5 gears, which was developed directly by Renault. In addition to the crossover, it is also installed on many other models of the Nissan, LADA and Renault brands.
Design
This model is a modernized version of its predecessor – JH3. According to the basic principles, they are very similar - a 2-shaft layout and the presence of synchronizers in all gears. The gearbox is combined with the main gear and differential.
However, there are significant differences:
- The clutch is hydraulically driven, whereas the JH3 had a cable clutch. At the same time, with hydraulics, the clutch engages noticeably softer.
- In the JR5, gears are engaged using 2 cables (flexible), unlike its predecessor, which uses a rigid rod. This solution reduced vibrations.
- The mechanics of the Renault Arcana JR5 are able to handle 200 Nm versus 160 Nm for the previous one.
The markings for this transmission are located on the bottom of the crankcase.
The body itself includes 3 elements:
- Gearbox housing;
- Clutch housing;
- Cover (rear) gearbox housing.
As already mentioned, the design uses a hydraulic clutch drive. In this case, the working cylinder and the clutch release bearing are actuated by one unit, which is fixed to the crankcase with 2 bolts.
An aluminum-based alloy is used to mold the crankcase of the Renault Arcana mechanics and the clutch housing, while the back cover is stamped from steel. Screws are used to secure the clutch housing to the transmission housing. During the assembly process, the joint between the crankcases is coated with a sealant with gasoline and oil resistant characteristics. The rear cover is secured to the gearbox housing using 3 bolts.
The input shaft is a block of drive gears that is in constant mesh with the driven gears at all forward speeds.
The shape of the gears depends on their type:
- Reverse gear – straight teeth;
- The forward drive is helical.
In this case, the gears of the 1st, 2nd, 3rd and 4th gears of the Renault Arcana mechanics work together with the input shaft, while the 5th speed gear rotates on the shaft (freely). The 5th gear synchronizer is located at the rear end of the input shaft. But the secondary shaft is made hollow inside to supply oil through it under the gears (driven).
On the shaft there are gears (driven) of 1st, 2nd, 3rd and 4th gears with synchronizers. But the V speed gear is on splines on the shaft.
The secondary shaft bearings are different, depending on their location:
- Ball - on the side of the lid.
- Roller – from the clutch housing side. Below it is an oil sump to ensure oil flow into the shaft.
Oil
Despite statements from the manufacturer, which claims that the transmission fluid is filled for its entire service life, its replacement is necessary. It is recommended to do this once every 60,000 km.
Resource
The company claims that the Renault Arcana MT resource is 250,000 km. However, if you properly operate the box and change the oil, it can travel more than 400,000 km.
Problems
As a rule, there are very few problems with manual transmissions. As for the complaints from drivers, they relate to not the most precise operation, vibration at idle and current seals.
Features of fifth gear on Largus
Along with the above malfunctions, Largus owners often have a desire to improve the performance of their car, or more precisely, to adapt it to personal requirements. In the main modification, the Lada Largus gearbox comes with a 16-valve engine. The fifth gear ratio (TR) is 0.892. This indicator indicates that the car can move confidently both in city traffic and outside the city. It easily picks up fifth gear from 50 km/h and dynamically reaches its upper speed limit, so there is almost no need to switch to fourth.
However, when driving for a long time at a speed of 90-100 km/h, increased noise occurs and increased fuel consumption is observed. This situation can be corrected by replacing the two fifth gears on the input and output shafts. Replacement takes place with gears that have a lower gear ratio, therefore, fewer teeth. These pairs of gears are sold in aftermarket gear ratios of 0.820, 0.795, 0.756 and 0.738. Experiments on replacing fifth gear gears were carried out by both AvtoVAZ and numerous car enthusiasts.
When using a pair with an IF of 0.820, the fifth gear becomes slightly shorter, as a result the car easily picks up a speed of 60 km/h both on an incline and when driving on a straight road. The noise from the gearbox operation becomes significantly lower.
Gears with a gear ratio of 0.795 slightly change the maneuverability of the Largus. When overtaking, you need to engage fourth gear more often to gain the desired speed. It is often necessary to switch to four when driving on the ground in a loaded car. As for the installation of gears with an IF of 0.756 and 0.738, they aggravate the listed disadvantages.
It is best to replace the factory gears with a pair with a 0.820 ratio.
Mechanics Renault Arcana 1.6 l TL8
This is a 6-speed gearbox for the French crossover, which is paired with a 1.6-liter engine and all-wheel drive. Manual transmission6 Renault Arkana TL8 was developed on the basis of the TL4 model and was initially aimed at all-wheel drive vehicles of the Renault-Nissan Alliance.
Design
This is a modern transmission that implements the following principles:
- 2-shaft arrangement;
- Control by 2 flexible cables;
- Synchronizers at all speeds, including reverse;
- Hydraulic clutch drive.
Torque is transmitted to the rear wheels through a driveshaft that is connected through a gearbox. To enable all-wheel drive, a special button is provided in the crossover interior, which closes the electromagnetic clutch.
Oil
As with the previous transmission, oil changes are not provided for by the factory. However, service stations recommend replacing them every 60,000 km.
Resource
As practice shows, the mechanical life of the Renault Arcana 1.6 TL8 is not impressive and is at the 150,000 km mark. However, if you don’t take your crossover off-road and don’t skimp on maintenance, its service life will increase significantly.
Problems
Like the JR5 model, the TL8 manual transmission has no obvious weak points.
As for the most common malfunctions, there is an oil leak through the seals, as well as background noise. In general, the mechanics of Renault Arcana 1.6 - both JR5 and TL8 - perform well. They are quite enough to work in tandem with the 114-horsepower crossover engine.
Reliability jh3
The JH3 gearbox is considered a reliable unit, therefore it is still relevant in the automotive market. Car owners prefer cars with a structurally simple gearbox, partly because of its accessible and cheap maintenance. The disadvantages of manual transmission boil down to the lack of a high level of driving comfort.
The gear shift does not always occur clearly and quickly; sometimes there are jolts and jerking of the vehicle. Structurally, the unit has been fully studied, so even in the event of a serious breakdown, its overhaul will not be difficult. Usually the lever for switching from one speed to another becomes loose ahead of time, which leads to unclear switching.
Often, owners of Lada Largus with JH3 note the noisy operation of the manual transmission and a crunching sound when engaging reverse mode. Early wear of the synchronizers cannot be ruled out. If we close our eyes to some shortcomings, we will get decent mechanics that can go 200-300 thousand km without a single repair. There are known examples of cars that have covered about 500 thousand km on JH3 without a single repair. Much depends on your driving style and quality of service. The oil change must be carried out in accordance with the maintenance regulations.
