Gearboxes are key components in automobiles, tractors, ships, machine tools and various machinery. They can change the torque, speed and direction of motion transmitted from the driving shaft to the driven shaft according to different usage requirements.
Gearbox slippage:
When you step on the accelerator, if you hear the sound of the engine idling and the vehicle's acceleration performance decreases, it may be a sign of gearbox slippage. This may be caused by reasons such as too high hydraulic oil level, clutch or brake friction pad wear, and burnt brake belts.
01
Gearbox oil leakage:
It seems extremely laborious when starting. When you step on the accelerator during driving, the speed increases but the vehicle acceleration is not obvious. This may be caused by gearbox oil leakage. Oil leakage will cause insufficient lubrication inside the gearbox.
02
The car cannot drive:
Whether the shift lever is in reverse or forward gear, the car cannot drive. This may be due to serious oil leakage in the automatic transmission, clogged oil inlet filter, serious leakage in the main oil circuit, and damaged oil pump.
03
There is impact when starting or driving:
The car has a significant impact when accelerating when starting or driving. This may be due to reasons such as too high engine idle speed, improper adjustment of the throttle cable or throttle position sensor, etc.
04
Late gear shifting, gear shifting jamming, gear shifting shock:
If the gear shifting takes longer than normal or there is a strong impact, it may be a problem inside the gearbox.
05
The vehicle cannot run:
The vehicle cannot reach the expected speed and accelerates very slowly. This may be due to the wrong gear position inside the gearbox, clutch burnout, mechanical failure of the converter, etc.
01
Engine idling:
A short period of slipping and idling during acceleration or gear shifting may be caused by problems with the clutch and other related links in the gearbox.
02
High engine speed during driving:
If the vehicle speed is too high during stable driving, it may be due to failure of the high gear of the gearbox or failure of the locking clutch inside the converter.
03
Too long or too short gear shifting time:
If the gear shifting time changes suddenly, it may mean that the gear ratio of the gearbox is not proportional.
04
Noise and vibration in the gearbox:
A broken gearbox may be accompanied by noise and vibration, as well as symptoms such as excessive oil temperature, weak acceleration, and slipping.
05
Whether the gearbox is prone to failure is related to factors such as the type of gearbox, the matching degree between the engine and the gearbox, and the driving habits of the owner. If the above symptoms occur, it is recommended to find a professional transmission repair shop for inspection as soon as possible to avoid further deterioration of the problem.
