Yes, this is common due to untrained mechanics:

Overfilling causes excess pressure, leading to fluid being forced out of seals.

Using the wrong transmission fluid type can:

Cause seal degradation

Affect gear synchronizer performance

Many local workshops don’t follow torque specs o r proper fill levels.

⛔ Conclusion: Unskilled service and improper filling lead to avoidable leaks and long-term transmission issues.
