Transmission fluid leaks in the BMW 2 Series can happen due to various reasons, especially considering Pakistan’s hot climate and road conditions.

Cracked Transmission Pan – Pakistan’s rough roads and speed breakers can cause the pan to crack.
Leaking Transmission Cooler Lines – These rubber hoses can crack due to heat and aging, causing leaks.
Faulty Axle Seals o r Output Shaft Seals – Seals wear out over time, leading to fluid leakage.
Overfilled Transmission – Too much fluid can cause excess pressure, leading to leaks from the vent o r seals.
