DIY Chevrolet Cruze gearbox repair

In detail: do-it-yourself Chevrolet Cruze gearbox repair from a real master for the site my.housecope.com.

The Chevrolet Cruze car has been present on the domestic market for almost 10 years. During this time, it has established itself as a reliable vehicle, all parts and assemblies of which are manufactured and assembled by the manufacturer with high quality.

One of the most critical components of the Chevrolet Cruze is no exception - its manual gearbox (manual transmission). All atmospheric engines of this model are aggregated with such a box. Subject to the rules of use and routine maintenance established by the manufacturer, the service life of the Chevrolet Cruze manual transmission is commensurate with the service life of the car as a whole.

Under the operating conditions of the Chevrolet Cruze car on domestic roads, it is quite difficult to provide a gentle manual transmission mode. Therefore, there may be cases of breakdown, and not only due to its too frequent use, but also due to careless gear shifting with an aggressive driving style. In this case, a manual transmission malfunction may occur suddenly or its symptoms may appear gradually, as evidenced by increased noise in the engine area, difficult gear shifting, the presence of oil stains under the car, etc.

For this reason, only qualified specialists with extensive experience in performing such work should be engaged in its repair. Such repairmen will be able to eliminate a simple malfunction without removing the manual transmission from the car, but intervention in its work by a person who does not have sufficient skills can lead to an aggravation of the breakdown and the need for complex and expensive repairs.

On Chevrolet Cruze cars with atmospheric power units, a five-speed manual transmission of the D16 model is installed. It is made according to a two-shaft scheme and has five synchronized forward travel gears and one unsynchronized reverse gear. The Chevrolet Cruze manual transmission and the main gear have a common crankcase. In addition, the gearbox also has an additional intermediate crankcase, which is closed with a special cover.

The input shaft is pressed into the gear block and connected to the last splines. The following are installed on the secondary shaft:

  • main gear drive gear;
  • driven gears;
  • gear synchronizers.

The gear shifting mechanism is located in the cover, which is installed on top of the gearbox housing. A cable drive is used to control the box. The gearshift knob is brought into the Chevrolet Cruze saloon and through a tunnel in the base of the body floor is connected with cables to the gearshift levers.

All manual transmission malfunctions arising during the operation of the Chevrolet Cruze can be considered as:

  • malfunction of the switching mechanism;
  • breakdown of the gearbox

Shift mechanism malfunctions:

  1. Critical gear shift fork wear.
  2. The drive cable is damaged.
  3. Traction damaged.
  4. Looseness of the tie rod fasteners.
  5. Breakage of the switching rod.
  6. The blocking device is deformed.

Gearbox breakdowns:

  1. Gears worn.
  2. Synchronizer couplings worn out.
  3. Worn spline connections.
  4. Failure of bearings.
  5. Loose gearbox fasteners.
  6. The oil seals are out of order.
  7. The transmission oil level has dropped below a critical level.

The gearbox is removed from the car if, while driving, the following take place:

  • loud noise;
  • spontaneous gear shifting;
  • transmission oil leaks through seals and gaskets.

The gearbox is also dismantled if gear shifting is difficult or impossible.

Maintenance of the manual transmission of the Chevrolet Cruze car comes down to regular checking the level of transmission oil in the box and visual inspection of the seals of the inner CV joints. If necessary, the gear oil is topped up, and the oil seals are removed and new ones are installed in their place. Carrying out these relatively simple procedures, the car owner can perform independently:

In this case, the dismantling of the manual transmission at the Chevrolet Cruze is not required.

The manufacturer recommends checking the transmission oil level in the Chevrolet Cruze manual transmission every 15 thousand kilometers. They control the oil level in the box body through a special hole. To do this, unscrew the plug that closes it. The surface of the oil should be at or slightly below the edge of the hole. If the oil cannot be reached with a finger or a screwdriver, then it must be topped up. Transmission oil is topped up through the hole located on top of the gearshift mechanism housing. It is also closed with a plug that will need to be unscrewed. A special syringe is used to fill the oil.

When pouring oil into the body of the Chevrolet Cruze manual transmission, all openings are closed with plugs.

The oil seals of the inner CV joints, if transmission oil leaks are detected, must be replaced.

To do this, the car is driven onto a lift (inspection hole) and the wheel drive is removed from the side of the leaking oil seal. Then the leaky oil seal is removed with a screwdriver and a new one is installed in its place using a mandrel of a suitable size. Having installed the oil seal, check the oil level in the box and add it (if necessary) to the set level. The process of replacing the oil seal is completed by installing all the removed parts in their places.

When operating a Chevrolet Cruze car, it is necessary to constantly monitor the operation of the manual transmission. There are a number of signs preceding the failure of the gearbox, when they appear, experts recommend visiting a service station and diagnosing it. These signs are:

  • fuzzy switching of gears;
  • gear slip when shifting;
  • extraneous noise in the box;
  • deterioration in dynamics when picking up speed;
  • transmission oil leaks.

Repair of the manual transmission of the Chevrolet Cruze car can be capital or partial. During a major overhaul, the manual transmission is dismantled and checked in full. After checking, all parts with increased wear must be replaced. In addition, all oil seals, gaskets, bearings, as well as the clutch assembly are changed.

Proceeding from the position that the work of replacing and repairing a gearbox on a Chevrolet Cruze is not an easy and time-consuming task, before starting dismantling it is necessary to make sure that the malfunction is associated with this unit. Let's consider the most common symptoms of automatic and manual transmissions malfunction.

  • the appearance of tremors when the car is moving;
  • slipping of the transmission when shifting to lower or higher gears;
  • the occurrence of non-standard noises, tapping, metal grinding, hum when switching and during movement;
  • complete impossibility, difficulties when turning on one or several gears, their spontaneous turning off;
  • excessive oil consumption as a result of oil leakage.

The reasons for this behavior are associated with natural wear and tear of parts and components, untimely maintenance and repair of the unit, non-compliance of the gear oil with the manufacturer's requirements.
