sorry, I'm no help on that since I've never looked at the guts of a
mechanical speedo. I'd expect that either cluster would have used the
same gears in the tail shaft, so for a given speed the cable should be
spinning the same speed (ignoring tire size and gears) and therefore give
the correct reading for either custer speedometer.

not quite. the valve body configuration is changed by each motion of the
shifter. the electronic part is that the line pressure is controlled to a
certian extent by the governor pressure solenoid. There's more electronic
control than just the lockup and overdrive, but it's more of electronics
controling solenoids that play with the line pressures than the
electronics directly acting on the guts of the trans.

you have a few options for traction additions - a factory limited slip, an
aftermarket limited slip or aftermarket locker. for street use either
limited is your best option. I kinda left my old 8.25" in the weeds at my
old apartment, I have no idea if it's still there.... but it was (is) a
limited slip.
