Yes. This is a major problem in Pakistan:

Overfilling can increase internal pressure, causing fluid to push out from weak spots.

Use of wrong fluid type non-compatible ATF/manual gear oil also causes:

Seal swelling o r shrinkage

Internal clutch wear

Many mechanics don’t follow factory torque specs o r fluid fill procedures.

⛔ Conclusion: Improper servicing by untrained mechanics often results in leaks and long-term damage.
