Hi, im in the process of changing the gearbox oil in my van (2002 y17dt engine), am i right in assuming it has the f17 gearbox?? ive already drained it and replaced the sump gasket but i am now unsure how much oil to put back in because only about a litre came out and ive read it takes 1.6l, also whereabouts is the level plug? is it by the nearside driveshaft.
