Please could I have some advice on whether or not to change my gearbox oil ? My car is Avensis 2002 1.8 vvti manual 106 000 on clock I don't think it has been changed before and ever topped up ...... Thought it might improve gear changing which has become a bit stiff recently . Somebody told me that this oil should last the life of car
-------- not sure about that ! Thanks for any help
