dumb thought, how about getting Jamie's OD gearset for an A833, and putting yourself on the waiting list for the A855? might even be able to work out a deal to trade in the 4 speed gearset when the 855 is ready? that way you can (eventually) get the transmission you want, while enjoying the car in the meantime without cutting it up.
I'm not the early adopter type at my expense. I like to see that something works before I start throwing money at stuff. To revert my whole car back to factory driveline would cost over 4 times what it costs me to have the TKO rebuilt, and twice as much as the Legend 5 speed. Both of which have a lot of R&D behind them. If Jamie wants me to put his transmissions through some torture tests for R&D at his cost I wouldn't turn down the opportunity.
