What is the problem that the big truck can t get in gear

1. Clutch wiring failure, some manual transmission cars.

Or use the wiring to control the clutch, the wiring sheath is easy to break and cause no clutch difficult to hang the gear, such a problem is relatively simple, just replace a wiring directly;

2. The gear of the clutch side.

If the self-locking force is too large, it is difficult to enter and exit the gear, in this case, it is recommended to go to the repair shop to adjust the clutch cable and gear lock;

3. Clutch master cylinder failure, clutch hydraulic master cylinder will have pressure relief or oil leakage failure during use, and there will be no gear when stepping on the clutch gear, so the clutch master cylinder should be replaced at the maintenance station, and the air exhaust operation should be carried out after replacement;

4. a gearbox.

Faults, such as insufficient transmission fluid, stuck transmission shift mechanism, or a malfunction of a gear or fork, can cause the car to be difficult to engage or not to be engaged. For gearbox problems, you also need to go to a professional repair shop for a detailed inspection.

Automatic. The reason why the car does not go after hanging D gear and how to deal with it.

1. When the signal of the position sensor of the gearbox shift valve of the vehicle is wrong, it cannot perceive what gear it is in;

2. There is a problem with the shift valve, the gear is not in place, and the oil channel cannot be opened;

3. The solenoid valve and electronic module of the gearbox are faulty;

4. The oil volume of the gearbox is too small, or the internal oil pressure is too low;

6. Handbrake. Didn't put it or didn't loosen it to the end.

Solution: If the car does not go after the gear, you should go to the repair shop in time for maintenance, and to reduce the probability of such a failure is to maintain the gearbox regularly, replace the gearbox and the filter on time, change the gearbox oil and clean the inside of the gearbox at the same time.

There are many problems that cannot be put into gear, the clutch master pump is out of oil, the sub-pump is leaking oil and air, the clutch plate is worn, and the pressure plate is pressed.

Summary. Hello. Friend.

Reasons and solutions for bad truck stalls:

1. The temperature of the car is low, and the transmission oil is not fully lubricated.

2. If you don't ignite, try a gear to hang it well, and it's okay to hang it well. 3. It is not easy to hang up when changing a gear while moving, and the speed and gear do not match. 4. There is no synchronizer in the first gear and reverse gear.

Workaround:1It is recommended to try to hang the reverse gear in the stationary state of the speed vehicle, if the gearbox is engaged in the reverse gear process, the gearbox makes a "click" gear impact sound, indicating that the clutch of the vehicle is not completely separated, and the fault can be eliminated after the clutch is repaired.

2.If the reverse gear is smooth, only one gear is not good to hang, it is recommended that you go to the repair shop to adjust the gear position, change the transmission oil, and the fault can also be eliminated. The manual transmission shifts gears at low speeds, requiring the clutch to be able to disengage thoroughly in order to be able to engage the corresponding gear.

Hope it helps.

What is the reason why the truck stall is not good.

Hello. Reasons and solutions for bad truck gears: 1. The temperature of the car is low, and the transmission oil is not fully lubricated.

2. If you don't fire and try Mingtong, you can destroy a good gear, and it's not good to hang up, and it's okay to hang it well. Wheel light 3, it is not good to hang in a gear while moving, and the speed and gear do not match. 4. There is no synchronizer in the first gear and reverse gear.

Workaround:1It is recommended to try to hang the reverse gear in the stationary state of the speed vehicle, if the gearbox is engaged in the reverse gear process, the gearbox makes a "click" gear impact sound, indicating that the clutch of the vehicle is not completely separated, and the fault can be eliminated after the clutch is repaired.

2.If the reverse gear is smooth, only one gear is not good to hang, it is recommended that you go to the repair shop to adjust the gear position, change the transmission oil, and the fault can also be eliminated.

Hope it helps.

I hope you can give me a thumbs up, your thumbs up are important to me, thank you.

If the lubricating oil inside the transmission is not fully lubricated, starting it for a while and then gearing can solve the problem.

If the transmission mechanism inside the transmission, such as gears, synchronizers or plugging and plugging parts are damaged, they need to be repaired.

If the clutch is not completely disengaged, you can try to press the clutch hard to the end to see if you can get in gear. If the clutch parts are damaged, it is also necessary to repair them, replace the friction plates, pressure plates and release bearings, etc. If it is difficult to hang the gear due to the wear of the shift push rod, you can hang it a few times to see if you can hang the upper gear, and if you can't hang it, you can only play ** rescue.

1. P gear locking solenoid valve failure; For safety reasons, to prevent the vehicle from being mistakenly hung into other gears when starting, there will be this P gear solenoid valve, which needs to receive the signal of the brake pedal before it is released.

Therefore, these two parts are related, and if one of them fails, the gear lever will not be able to push out of the P gear and hook into the other gears.

Solution: Replace the P-gear solenoid valve to solve the problem.

2. There is a fault inside the gear lever assembly, and the gear inside the gear lever is worn, which causes the gear lever to be stuck, and it is very difficult to pull back and forth, so it leads to the failure to hang the gear and the difficulty of hanging the gear.

Solution: Repair the gear lever to solve the problem.

3. The clutch is not completely separated, which may be caused by the failure of the clutch plate and the clutch plate pressure plate.

Solution: Generally, the clutch three-piece set (friction plate, pressure plate and release bearing) should be replaced.

The gear lever positioning control fails, and the gear cannot be accurately controlled, such as the spherical working end of the lower end of the gear lever of some models is damaged or worn off, and the gear lever cannot control the fork to make it difficult or out of order.

The clutch system is short of oil. The clutch disengagement is not complete.

It may be that the clutch can not be completely disengaged, and this fault can be solved by adjusting the clutch or replacing some clutch parts so that the clutch has a suitable free clearance and separation clearance.

Clutch cylinder failure, such as oil leakage or damage to itself.

The platen is faulty and needs to be replaced.

There is a possibility of fork failure, such as a fork that is bent and deformed, loose, or badly worn. Causing it to be out of gear. In this case, the transmission cover should be opened for inspection, service, and if necessary, the fork should be replaced.

Find a repair shop to adjust the clutch now, if not, consider replacing the clutch plate and pressure plate or the variable box for overhaul.

If the vehicle does not hang out of gear, it is generally due to damage to the transmission synchronizer. The method of judging is also very simple, you try to press the following two feet to see if you can hang up the gear:

1. Step on the clutch; 2. The gear retreats to neutral; 3. Release the clutch, 4. Hit the throttle; 5. Step on the clutch; 6. Hanging gear.

If it can be hung up in this way, it must be that the synchronizer is damaged and needs to be repaired in a repair shop.

Generally, there are two main reasons: one is that the clutch plate is broken, and the other is that the gear part is broken (such as the gear lever, gear line). The clutch plates are broken, replace the clutch plates.

If the gear part is broken, replace the corresponding parts. If you can still go with a dual-drive drive, and the transmission shaft is still rotating, it is likely that the half shaft is broken.

The specific cause needs to be examined by professionals to determine, and only by determining where the problem is can the symptoms be repaired. The gears of trucks are generally 8 gears, 1 4 gears are low-speed gears, and 5 8 gears are high-speed gears. Trucks generally start in 2nd gear and gradually move up the gears.

If you start in high gear, it will increase the wear and tear on the car. Unless there are special circumstances, it is not allowed to skip the shift. Generally, high-speed gears are more fuel-efficient than low-speed gears, so after starting, you should upshift step by step, and don't drag the gear.

When the car is driving, it suddenly feels that the acceleration performance has deteriorated, the transmission seems to be out of neutral, and the car slowly stops; Or when the car starts in gear, the car does not move. The location of the fault should be identified first. If the two rear wheels are thrown out, it may be that the half-shaft casing is broken or the wheel bearing lock nut is out of place.

If it is normal, it should be judged according to the dynamics of the transmission shaft when the gear starts.

If the propeller shaft rotates but the car cannot move, the fault is on the rear axle. When jacking up the rear axle and rotating one rear wheel, if the transmission shaft does not rotate and the other rear wheel reverses, it means that the driven bevel gear rivets are all cut off. If the other rear wheel does not rotate, the half shaft should be dismantled and checked for breakage.

After the car starts, the transmission shaft does not rotate when it is in a certain gear, indicating that the fault is in the transmission. The transmission cover should be removed and the transmission fork should be checked to see if it is broken and whether the guide block fixing screw is falling off.

When the transmission is in any gear, the transmission shaft does not rotate, which is a clutch failure. It should be checked whether it is seriously slipped, whether the clutch driven disc spline tooth and the steel rivet are all cut off or the steel plate is broken.

The situation of not taking the gear may be due to the clutch or because the gear is not entering.

The maintenance of new cars should be done sufficiently, most car owners will go to the special service station to do maintenance in accordance with the manufacturer's regulations, because most car manufacturers have implemented the first warranty free oil change discount for new cars. For example, Shanghai GM will provide 4 free oil and oil filter replacement services during the warranty period.

However, there are also a small number of car owners who neither consult the staff nor read the "Maintenance Manual", so there are also examples of missing the first warranty. Since it is a new car, the owner misses the first warranty.

Production and sales data:

According to the latest statistics, from January to December 2010, the national truck production and sales of 10,000 and 10,000 vehicles, a year-on-year increase and. In December, the production and sales of trucks were 10,000 and 10,000 units, an increase from the previous month; year-on-year growth and.

In 2010, the production and sales of trucks were 10,000 and 10,000 units, a year-on-year increase and; The production and sales of semi-trailer tractors were 10,000 and 10,000 units, a year-on-year increase and; The production and sales of non-complete trucks were 10,000 and 10,000 units, a year-on-year increase and.

If the vehicle is broken, find a professional master to check it.

Summary. Hello, the truck can't hang up, the vehicle can't hang up, and the gearbox synchronizer is generally damaged.

Hello, the truck can't hang up, the vehicle can't hang up, and the gearbox synchronizer is generally damaged.

The method of judging is also very simple, you try to press the following two feet to see if you can hang up the gear: 1. Step on the clutch and start the clutch; 2. The gear retreats to neutral; 3. Release the clutch, 4. Hit the throttle; 5. Step on the clutch; 6. If the gear can be hung on the bridge in this way, it must be that the synchronizer is damaged and needs to be repaired in the repair shop.

What's going on with the pickup truck hanging in 5th gear and not being able to hang up and automatically rebound.

Pro, the gear gear is seriously worn and cannot hang the gear, it is recommended to go to the 4s or auto repair shop to check and replace it.

Other gears can be hung, but 5 gears can't be hung.

The car can't hang up the 5th gear, and the other gears can be hung 1. The gear ring of the fifth-gear synchronizer is worn out and the gear ring cannot be hung 2. The transmission control mechanism is faulty 3. The fork of the shift mechanism in the transmission is worn or bent and deformed; Shift fork guide rail wear and deformation 4, synchronizer wear or damage 5, transmission bearings, bushings, gaskets and splines and other wear, transmission shaft or variable shield speed guard gear sliding or shaking before and after 6, gear locking mechanism locking disc cam guide or locking cam wear or damage 7, gear selection shift shaft wear 8, gear locking mechanism tension spring or external control mechanism compression spring failure 9, shift connector failure.

Summary. Hello, the truck stall is not easy to hang, the relevant reasons and treatment methods are as follows. The first is this phenomenon caused by incomplete clutch separation, first check the clutch master pump and sub cylinder.

The second situation is that the clutch pressure plate and clutch plate of the vehicle are aged and worn out, and this phenomenon needs to be replaced with a clutch three-piece set. The third situation is caused by the wear and tear of the gearbox gear mechanism or the internal related gears, which needs to be checked for the gear mechanism and internal gears.

Hello, the truck stall is not easy to hang, the relevant reasons and treatment methods are as follows. The first is this phenomenon caused by incomplete clutch separation, and the clutch master pump and sub pump are first checked by the limb source. The second situation is that the clutch pressure plate and hungry clutch plate of the vehicle are aged and worn out, and this phenomenon needs to be replaced with a clutch three-piece set.

The third situation is caused by the wear and tear of the gearbox gear mechanism or the internal related gears, which needs to check the gear mechanism and the internal part of the gear.

Filing can be that there is no time and space in the entry and neutral space.

Then this is the key point to check the gear mechanism to see if the gap is too large?
