To identify and fix transmission fluid leaks in your S-Class:

Check Fluid Level and Color: Low fluid o r dark, burnt-smelling fluid indicates a leak o r problem.

Look for Visible Signs: Transmission fluid is usually red o r amber and slick. Check under the car for puddles o r wet spots.

Inspect Around Common Leak Points: These include the transmission pan, cooler lines, seals, and the torque converter.

Use a UV Dye Test: Some mechanics add a UV dye to the transmission fluid to trace leaks with a UV light.

Fixing the Leak:

Replace worn o r damaged seals and gaskets.

Repair o r replace damaged transmission cooler lines.

Tighten o r replace the transmission pan gasket.

Flush and replace old transmission fluid.

For severe damage, transmission component replacement may be necessary.

Always consult a qualified technician experienced with Mercedes vehicles, especially in Pakistan where specialist knowledge is key due to local conditions.
