scottalej Posted June 20, 2011 Share Posted June 20, 2011 Hi all, I'm new on here and looking for help on my recently acquired 2005 Legacy Spec B 3.0 manual. This has a drain plug under the diff which is shown in the manual but behind that there is a sump with another drain plug on that. :-\ Should both of these plugs be removed to properly drain the gearbox oil? Do they both have washers and if so do they really need to be replaced? Link to comment Share on other sites More sharing options...
idosubaru Posted June 20, 2011 Share Posted June 20, 2011 washers don't need replaced. actually...i never replace them, ever. so i've driven like 100,000 miles on the same washer before. owners manual should have information about maintenance procedures and fluids like this. it's a manual transmission you say?

scottalej Posted June 20, 2011 Author Share Posted June 20, 2011 Yeah, 6 speed manual. The workshop manual just shows the drain plug under the diff but the small sump to the rear of it must be the gearbox as well? It's not a seperate front diff on these like the autos.

idosubaru Posted June 20, 2011 Share Posted June 20, 2011 two drain plugs to get all the fluid out: http://www.iwsti.com/forums/how-install/96096-changing-6mt-trans-oil.html some newer 6 speeds don't have a dipstick or fill tube on the top, they're filled from the side. that change isn't until later 2000's though i don't think.

scottalej Posted June 20, 2011 Author Share Posted June 20, 2011 That looks just like it. Thanks very much. I can't get a decent workshop manual which properly covers the UK Spec B. Link to comment Share on other sites More sharing options...
