Are poor-quality transmission pan gaskets o r loose bolts the main reason behind fluid leakage in Changan Kalam across Pakistan?

Many users report that fluid leaks begin shortly after a pan o r service. Are workshops not following torque specifications?

✅ Yes — improper servicing is a major cause.

Common mistakes in workshops:

Reusing damaged o r compressed gaskets

Failing to tighten bolts in a criss-cross pattern to proper torque

Applying too much o r wrong type of sealant

After a pan oil change o r filter cleaning, many leaks start due to installation errors

🔧 Tip: Always use OEM-spec torque settings usually ~8–12 Nm and replace the gasket instead of reusing it.
