Electronic shifting and about 6 gears with a lockup converter strong enough not
to break would be the real deal.. You benefit from the converter multiplication
at low speed but lock it up in high gear so no slip. The electronic shifting if
it could be programed would make the torque delivery optimum for each gear
without shocking the tires.. Smells a lot like F1 technology to me. It would
probably all be construed as traction control though as I believe some of these
units have torque sensors and wheel speed sensors tied into them..

If i was smart enough to build a transmission which I am not, I would run the
engine at a constant speed (peak hp) and apply torque to the track that is
bounded by a couple of factors. The first would be the accel rate the track can
stand determined by the friction coefficient and weight of the vehicle. 
Bonneville seems to work out to about 0.61 g. The transmission would then
infinitely reduce gearing while maintaining accel rate and engine speed within a
couple of hundred rpm..
