Transmission slipping can be caused by several factors, including low transmission fluid levels, worn-out components, or software issues. Regular maintenance and timely fluid changes can help mitigate this problem.
Harsh Shifting
Another frequent issue is harsh shifting, which can make the driving experience less enjoyable. Drivers may notice:
- Jarring or abrupt gear changes

- Increased engine RPMs before shifting occurs
Harsh shifting can stem from a variety of causes, including low fluid levels, a malfunctioning transmission control module, or worn-out clutches. Addressing these issues promptly is crucial to prevent further damage.
Overheating Transmission
Transmission overheating is a serious concern that can lead to significant damage if not addressed. Signs of an overheating transmission may include:
