 Car manufacturers still write in manuals that transmission oil ( Manuel and automatic),and differential oil is filled for life.
So replace that oil on a regular basis will gif you a longer life and less replacement of those units at the dealer, for al lot of money.

So it’s always good to replace gear oil, surtenly when it’s 40 years old.
