Now China's car to run around, especially the holiday attractions, the car went out are not good out. Now the driver's license has almost become a standard for young people, then the final two parts for the car, one is the engine, the second is the gearbox. So today we are talking about the car's brain "gearbox" before the failure of the signs.
1, hanging file difficult
There are still many people practicing manual block technology, a foot brake, a foot clutch, hand shift lever, and music is not he, willingly. Despite the simple operation of the manual gear, manual gearbox is still possible to go wrong.
The common problem is that when you press the clutch pedal and try to move the shift lever, the gearbox can not hang up the gear. This may occur when it stops from entering the first gear, or it may be shifting up or down. Common reasons include the transmission fluid is too low, the gearbox fluid viscosity is not (fluid viscosity is too thick), or shift cable or clutch linkage need to be adjusted.
2, automatic transmission can not upshift
On the way to the automatic transmission can only rise 1 block, can not rise 2 block and high speed gear; or can rise 2 block, but can not rise 3 block or overspeed.
Should check the adjustment throttle cable and throttle position sensor; check the speed sensor; check the gear switch signal. Measure the governor oil pressure, if the speed increases after the governor oil pressure is 0 or very low, indicating the governor is faulty or oil spill. If the control system is fault free, check the automatic transmission, check whether the gearshift actuator is skid, check the clutch, brake cylinder or piston for leaks with compressed air.
3, the production of odor inside the box
Gearbox is to work by hydraulic oil, when the oil temperature is too high, will produce some burning, these smell will come out, which means that some of the actuator parts of the gearbox work is not normal.

3, the production of odor inside the box
Gearbox is to work by hydraulic oil, when the oil temperature is too high, will produce some burning, these smell will come out, which means that some of the actuator parts of the gearbox work is not normal. Automatic transmission is different from the normal gear mechanism of the manual transmission, the structure contains multiple sets of friction and brake pads, while the use of special hydraulic shaft. Gearbox oil due to different models, the friction coefficient will be different, so the owner in the choice of transmission oil, try to choose the original oil, the use of original oil products can maintain a good mechanical gear, to extend its service life (car Maintenance manual will be prompted to use what type of gearbox oil).
4, slip gear
Normal operation of the gearbox, when the car stops, the gearbox gear should stop at your designated gear, perhaps the computer specified to maintain a certain range of speed range until you or the computer launch shift. But the gearbox gear automatically slide, the car can consciously jump out from the drive gear, turn to neutral. At this time the owner should be careful, should be issued to the car in time to repair 4S shop.
5, into the block car does not move
After the start of the car will be hanging D or R block, the release of the brakes, the vehicle without any reaction, do not move forward. Manual hanging 1 block, release the clutch, the car is not driving.
It may be that the gearbox input shaft or the reverse gear clutch is damaged, or the D / R brake is damaged. It is also possible that the gearbox is leaking, resulting in a serious lack of gearbox oil, or a connecting rod or cable between the vehicle shift lever and the manual valve rocker, causing the manual valve to remain in neutral or parking position.
6, oil spills
Gearbox oil and engine oil similar, mainly from the lubrication, cleaning, cooling, rust, sealing. When the gearbox is in operation, there will be high temperature and high pressure. If the gearbox is leaking, it will need to replace the gear according to its wear. You can ask the repair staff in the dissolution of the gearbox when there is no gear grinding, if you just change the gearbox oil and sump, then open two hundred kilometers and then check the shop to check.
7, automatic transmission abnormal sound noise
The car at idle or driving and high-load driving process, hear the transmission has abnormal sound, or even a lot of noise, in the gear when the rhythm of the rhythm of the switch. Long-term high temperature conditions, gearbox oil wear resistance and lubrication performance degradation, gearbox bearings, gears, parts wear or serious wear, or gear side damage.
8, automatic shift time is too long
General automatic gearbox is a specific shift speed and speed, if you find the shift time suddenly too long or too short, which means that the gearbox transmission ratio is not proportional, and will feel the engine speed is too high, the situation What is worse is the gearbox does not shift, which shows the gearbox is a problem.
