I am assuming they are still using the ZF 722.6 variant in those later cars. Those transmissions are great. There are a few issues with the printed circuit board, but overall they are awesome units and very durable to boot. The circuit board snaps on to the top of the valve body and can be changed out in half an hour. And they are extrememly easy to build. The entire internals with planetaries and drums come out and load in as one unit.
