Have been doing a bit of googling on the net and it seems that there are now a number of after market stand alone auto box controllers which can be used on Toyota, GM, and Ford boxes.

A whole lot more info is about now on the net for those wishing to do these upgrades. I had been always a bit put off by doing the ZF-4HP conversion as to me it is old tech and only really gives advantage in out of city cruising over my existing BW65 but with the later 6,8 and now 10 speed boxes with better ratios , spreads and box efficiency I will be looking a lot harder at this.
Another nicety that appears in the ZF 8 speed is the ability to fit an electric motor instead of the torque converter which obviates the need for a starter motor and also can be used on demand for extra oomf if required, makes a nice party trick for a P6 as the motor is rated around 40KW making the car effectively a Hybrid.
