Do you remember the 80's?  When GM continuesly made a bunch of 
unreliable automatics?  TheTHM 400R4  which was the" new and 
improved"  THM700R4(the original bomb) and now the 4L60E  which is 
the  THM400R4 with ECU controls. This particular design was dropped on 
the American public in 1982 and it took  GM  10  years to build in the 
reliability(1992). 
Is GM somehow better in Europe? 
Is this the new "now we will be reliable" GM ?


I suspect the real issue is a cost savings here as far as BMW AG goes.
ZF should have resolved the durability issues by 1993 in  the 4hp22/24 
but, the cost was higher .
