The MB fluid will be fine but you might wish to use this: http://www.redlineoil.com/products_gearlubricants.asp?productID=38&subCategoryID=15&categoryID=6

The difference is that without friction modifiers the clutches will stick. Not great for street driving but good for the track. Both of those Redline products are synthetic.
