Why is my Suzuki Swift’s transmission not shifting properly?

When I try to shift gears, my Suzuki Swift sometimes refuses to shift properly, and the transmission gets stuck in one gear, either too high o r too low. This issue happens frequently during acceleration o r deceleration. Could this be a sign of transmission failure, and what are the possible causes of this problem?

If your Suzuki Swift’s transmission is not shifting properly, it could be due to several issues related to the fluid, the transmission control system, o r worn components.

Common Causes:

Low o r Dirty Transmission Fluid: Low fluid levels o r dirty fluid can cause the transmission to fail in shifting properly, especially between gears.

Faulty Transmission Control Module TCM: The TCM controls the shifting in modern automatic transmissions. If the TCM is malfunctioning, it can result in improper o r delayed shifts.

Worn Gears o r Synchronizers manual: For manual transmissions, worn gears o r damaged synchronizers can make it difficult to shift.

Clutch Problems manual: A worn-out clutch o r pressure plate in a manual transmission can cause the transmission to fail to engage o r shift smoothly.

Faulty Solenoids automatic: Transmission solenoids control the flow of fluid. If they malfunction, the transmission may fail to shift properly.

Fixes:

Check the transmission fluid for proper levels and condition. If the fluid is low o r dirty, replace it.

For automatic transmissions, diagnose the TCM for faults o r programming issues.

Inspect and replace worn gears o r synchronizers in manual transmissions.

If you have a manual transmission, inspect the clutch and replace it if necessary.

Inspect solenoids and replace faulty ones if your Swift has an automatic transmission.
