What are the common causes of transmission fluid leaks in a Mercedes-Benz S-Class in Pakistan?

My Mercedes-Benz S-Class has started leaking transmission fluid. Considering the local driving conditions and climate in Pakistan, what are the most common reasons for this issue in the S-Class? How can I diagnose where the leak is coming from and what typical parts might be involved?

Transmission fluid leaks in a Mercedes-Benz S-Class can be caused by several factors, especially considering Pakistan’s climate and road conditions:

Worn Seals and Gaskets: Over time, seals and gaskets like the pan gasket o r output shaft seal degrade due to heat and age, leading to leaks.

Damaged Transmission Pan: Rough roads o r debris can damage the transmission pan, causing cracks o r loosening bolts.

Faulty Transmission Cooler Lines: These lines, responsible for circulating fluid to the cooler, can develop cracks o r wear out.

Overheating: Frequent stop-and-go traffic and high ambient temperatures in Pakistan can cause overheating, breaking down seals faster.

Improper Fluid Levels o r Old Fluid: Low o r old transmission fluid can cause internal pressure issues, resulting in leaks.

A professional mechanic can help identify the exact source by inspecting the transmission system carefully.
