Automatic Transmission (Introduction And Basic Inspection)

Synchronization refers to the equalization of rotational speed and positive connection between the output shaft and respective idler gear. Frequent shift operations with short shift times in combination with reduced shift force require an effective synchronization system.

Generally, a distinction is made between the following synchronization types:

• Multiple-cone synchronization (1st to 3rd gear)
• Dual-cone synchronization (4th to 7th gear)
• Single-cone synchronization (reverse gear)
