A manual transmission, also known as a “stick shift,” requires the driver’s active involvement in changing gears by manually engaging and disengaging a clutch. This type of transmission offers greater control over gear selection but demands more skill and coordination from the driver. Common issues that may arise include worn-out clutches, damaged synchronizers, or improper adjustment of linkages.

Continuously Variable Transmission (CVT):
The continuously variable transmission (CVT) represents a newer technology designed to provide seamless acceleration while maximizing fuel efficiency. Unlike traditional transmissions with fixed gear ratios, CVTs use pulleys and belts/chains to create an infinite number of gear ratios within specific ranges. Although CVTs offer improved performance and efficiency, they can face challenges related to belt slippage, software glitches, or overheating due to excessive friction.

Transaxle System:
A transaxle combines both the functionality of a transmission system and differential into a single unit used primarily in front-wheel-drive vehicles. By housing these components together, it reduces weight and takes up less space compared to separate units employed in rear-wheel-drive cars. Transaxles can experience issues such as bearing failures, gear wear, or differential noise, potentially leading to poor performance and decreased fuel economy.
