Somehow i could not find a link to DIY procedure in 2 minutes - if anybody knows please post here a link of where drain plus is located and how entire process works with recommended oil selections. I hope it got to be simple enough process to do.
Again, it is not about engine oil - it is about gearbox. Thanks!
