In older vehicles 10 k interval was specified for gear oil change (Complete drain out and change).
Though level is usually topped up by check ups.
In newer ones- 20 k interval is regular check up time, and compkete draining is by 50 k km.
You can ask your mechanic to check the level of gear oil.
Do you find unusual jerks in gear getting onto slot, or any other cons,then check the level.
It won't get sooty like engine oil also.Only the viscosity reduces by slight amount.
