Actually changing Gb oil is to jaga the Gb like how we jaga our engine when we change engine oil... Part of maintenance...
It is not meant to make diff like increasing HP n make ur car more powerful.
But it do really make ur gears (auto GB for tis case coz mine is auto) shift smoother n quieter after changing GB oil.
So some ppl will say change GB oil alr will make ur car more powerful.... Actually is juz that everything goes smoother so u end up feeling more power...
