Why Is It Difficult to Shift into Reverse Gear in a Manual Transmission?

[OElena]

Difficulty in shifting into reverse gear in a manual transmission is often due to the clutch not being fully depressed. No Synchronizer: The gear teeth may be misaligned. Many modern cars do not have a synchronizer installed for the reverse gear, so when attempting to shift into reverse, the teeth of the two gears might align incorrectly, causing the gear to get stuck and making it difficult to engage reverse. In such cases, simply shift back into a forward gear and then try shifting into reverse again. Synchronizer: Here’s an additional point about what a synchronizer is. When shifting gears, especially from a higher gear to a lower one, it’s easy to cause impact between the gear teeth or spline teeth. The role of the synchronizer is to prevent this kind of impact.
