The gearbox pole is broken.
When a transmission pole is broken, you first need to determine what type of transmission pole it is, because different types of transmissions may have different structures and maintenance methods. For example, the manual transmission is mainly composed of gears and shafts, which produce variable speed and torque through different gear combinations; The automatic transmission AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, through the combination of hydraulic transmission and gear to achieve variable speed and torque.
If the transmission pole is broken, it may affect the normal function of the transmission, for example, the gear inside the gear shift lever is worn, resulting in the gear shift lever stuck, and it is very difficult to pull back and forth; The P stop lock solenoid valve in the gear shift lever is faulty, and the brake switch is faulty. The incomplete clutch disengagement may be caused by the failure of the clutch disc and the clutch disc pressure plate.
For the replacement or repair of the transmission pole, if the shift lever fork of the manual transmission is damaged, it may be necessary to disassemble the transmission cover for replacement; If the pull rod of an automatic transmission breaks, it may be necessary to replace the lever assembly. The exact cost of repair and replacement parts may vary depending on the model and the extent of the damage, it is recommended to consult a professional automotive repair service for diagnosis and quotation.
What if the gearbox fault light is on
When the gearbox fault light is on, first of all, park the vehicle in a safe place as soon as possible, and contact a professional automotive maintenance technician as soon as possible for diagnosis and maintenance. Transmission fault lights can come on for a variety of reasons, including excessive transmission temperature, missing or deteriorating transmission fluid, transmission gear slipping, and system false positives. When the fault light suddenly appears on the road, you can pull over and stop safely, and after restarting, it can generally return to normal temporarily, but then it should be driven at low speed as soon as possible to the maintenance organization for inspection.
If the vehicle can continue to drive when the fault light is on, it is recommended to drive at a lower speed to the nearest maintenance point for inspection. In the process of driving, if you feel any abnormal vehicle, such as weak acceleration, abnormal sound, etc., you should immediately stop and contact the maintenance service. It is important not to ignore the transmission failure light, and timely maintenance can prevent electronic or mechanical problems from spreading throughout the valve body, which can lead to more serious problems.
Transmission leakage
The causes and solutions of transmission oil leakage mainly include:
Oil seal journal oil leakage: replace the aging deformation of the oil seal, repair or replace the journal.
Oil leakage on the joint surface of the box: properly thicken the paper pad at the damaged area, weld and repair it, replace the sealing paper pad, and tighten the screws.
Oil leakage at the bearing front joint: Keep the transmission vent unblocked, reduce the pressure in the box, and prevent oil leakage.
Damaged pipeline: Replace the pipeline.
Shell rupture: It is recommended to go to the 4S shop for professional maintenance.
Oil drain plug, fuel plug, link screw loose or slip: to the auto repair factory for reinforcement.
Improper use of lubricating oil: Find a professional to add lubricating oil.
Transmission shaft oil seal leakage: remove the gearbox, manual gear remove the separation bearing, automatic gear remove the torque converter to replace the oil seal.
Transmission oil radiator leaks: Replace the transmission oil radiator with a new one.
Overfill: Drain some transmission fluid.
The cost of repairing or replacing a transmission leak varies by model, location and repair shop. In general, the cost of replacing the oil seal may range from several hundred to several thousand yuan, and the specific cost needs to consult the repair shop according to the actual situation.
