Gear box is a devices that transfers the engine power and torque to the drive
load. It is present between the between the engine and the drive load.A problem
in the gear box means the problem in the transmission of power to the final
drive. Gear box repairs can be costly. So, it is necessary to understand the
gear box problems to avoid them. Some of the common car gearbox problems along
with their causes are listed below.
Lack of acceleration response
In this problem, the driver will notice that the car transmission systems
delay the acceleration pic after shifting the required gears. If the
transmission is manual acceptable delay range is one second. If the car speed is
not increasing but the rpm of the shaft increases, it will be a problem that
needed to be resolved immediately. Common causes for lack of acceleration
response are listed below.
- Faulty clutch component
- Damaged clutch plates
- Damaged clutch springs
- Damaged master cylinder
- Air bubbles in the fluid linings
- Collective parts damage
Gearbox oil leakage
(common car gearbox problems)
If you see oil leakage from your car it may be a gear box problem and need
to be fixed because fluid leakage will decrease lubrication. Common causes for
gearbox oil leakage are listed below.
- Fault in the lube oil storage pan
- Seal breaking
- High oil level than required.
- Gap in transmission
- Leak in fluid lines
-
Low fluid creates the friction in transmission system.
Vibrating car with grinding sound while gear shifting
If the driver observes a grinding sound accompanied with car vibrating
while shifting gears it means, there is problem with the gear box. Common causes
for Vibrating car with grinding sound while gear shifting are listed below.
- Damaged clutch plates
- Gear synchronization problem
- Gear teeth chipping
- Inappropriate lubrication
Gears slipping
(common car gearbox problems)
In this problem, the gear slip while the driver is shifting gears when he
accelerated the vehicle. The gear may slip to the previous gear or to the
neutral gear. Common causes for gears slipping are listed below.
- Torque converter failing
- Damaged shift fork
- Chipped gear teeth
- Insufficient lubrication
- Burn out fluid
-
Leakage in
transmission fluid
-
Worn out transmission band
Burning smell
In this problem, the driver will smell the lubricating oil burning while
shifting gears. Common causes for burning smell are listed below.
- Transmission fluid overheating
- Inappropriate lubrication
Problem in shifting gears
In this problem, the gear stick and does not change. However normal
requirement for gear shifting is that it should respond to the gear shifting
with no delay. But if driver face this problem it means that gear box is not
responding to the gear shifting lever
. Common causes for
problem in shifting gears are listed below.
- Clutch linkage not working well
- Worn out clutch cable
- For automatic transmission problem may be in electronics
- Blocked shifting mechanism
- Low fluid in cylinder
