NO--good, properly done strain gauges on a standard drive shaft would do it.

 If so, put in an inductive device to charge the battery for the transducer
as well, and a centifugal switch

If you are saying you have a way to pick up the output from the gauge
bridge on the shaft without slip rings, PLEASE give more details--because I
already have a tranny with an hydraulic retarder which turns at converter
turbine speed (and a lock up clutch), So I wanna put the strain gauge
bridge on the flexplate. But slip rings would be a machinist's nightmare in
this location. With a non-contact pick-up, I would have a dyno!!

TIA for any ideas--Although, as I write, the idea of putting the bridge
onto the converter housing--picking up REaction instead of action-- has
popped into my head! Have to ponder on that one some!! Might only require
enough dyno time to calibrate the bridge output!

TIA for more ideas!!
