The 5 Speed Automatic Transmission from ZF was initially marketed as having a " Lifetime Fluid ".  From years of experience, it was learned that the fluid did last longr than ordinary ATF, but it wasn't lasting a Lifetime.  The Biggest Maintenence Challenge in these Transmissions is changing the fluid.  With Normal Driving, in a BMW, which is mildly agressive, the fluid should be changed at each 60,000 miles.  To help get the fluid into the Transmission and Check the fluid level and condition, I have developed a " Classic Dip Stick ".
