    Dextron ATF works just fine and you fill it in the dipstick tube.

    The Correct Fluid for your German Made car Is Pentosin ATF 1. Made specifically for your car and lasted a long time between service intervals changes other fluids work but not as good. Electronic components such as Converter Clutches really respond to the Synthetic properties Of Pentosin ATF 1 No. A 0019892203. Info from My Mechanic In Germany. P.S. Can be purchased at your Local Parts house.
