What is the reason for not being able to engage the reverse gear in a manual transmission?
1 Answers
Manual transmission reverse gear cannot be engaged because: the clutch pedal is not fully depressed, and the gear teeth happen to align. Here is some relevant information: 1. Inside the structure of a manual transmission, there is a very important device called the "synchronizer." Without a synchronizer, forcibly inserting a slowly rotating gear into a high-speed rotating gear will definitely cause gear grinding. 2. The function of the synchronizer is to increase the speed of the gear to be shifted to match the speed of the output gear when shifting occurs, so that there will be no gear grinding when shifting. This makes it easy to engage the gear.
