    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.
