What causes the transmission in my Suzuki Cultus to slip?

Transmission slipping occurs when the car unexpectedly changes gears o r fails to maintain the selected gear. This can result in a loss of power, poor acceleration, o r jerking movements.

Common Causes:

Low o r Contaminated Transmission Fluid: Low fluid levels o r dirty transmission fluid can cause the transmission to slip. Fluid is responsible for lubrication and hydraulic pressure, so a lack of it can prevent the gears from engaging properly.
Worn Clutch Manual Transmission: A worn clutch in manual transmissions can cause slipping when the clutch fails to properly engage o r disengage from the flywheel.
Worn o r Damaged Transmission Bands: In automatic transmissions, bands help engage the gears. Over time, these bands can wear out, causing slippage.
Faulty Solenoids Automatic Transmission: Transmission solenoids control the flow of fluid in an automatic transmission. A malfunctioning solenoid can cause erratic shifting o r slipping.
Internal Transmission Damage: Internal components like gears o r bearings could be worn o r damaged, causing transmission slipping.
How to Fix:

Check and Replace Transmission Fluid: Inspect fluid levels and replace it if its dirty o r low. A fluid change might solve the problem if slipping is caused by insufficient fluid o r contamination.
Inspect the Clutch Manual Transmission: If the clutch is worn, it will need to be replaced. A worn clutch is one of the main causes of slipping in manual transmissions.
Replace Worn Transmission Bands o r Solenoids Automatic Transmission: If the bands o r solenoids are the cause, replacing them will stop the slipping. These repairs should be done by a qualified technician.
Inspect Internal Components: If no external issues are found, internal transmission parts may be damaged. A full inspection is required to identify and repair o r replace any damaged internal components.
What to Do:
Start with checking and changing the transmission fluid. If the issue persists, have the clutch, solenoids, o r internal components checked by a mechanic.
