2006 with 10,000 mi. The owners manual is vague in some info. I want to change the trans. and diff. fluid but the manual does not tell the capacity of either. Also it just says to use manual trans. fluid but what kind of fluid is it. What will substitute for it. Is it 75w/90 that the diff. uses or something different. I know to fill till it comes out of inspection hole but how much do I need to buy? Thanks.
