Overdrive on a switch?

[BC847]

On a RH controlled trans, is it possible to, by way of a switch, engage OD and be able to start a dyno-pull at a very low wheel-speed?

- Or would the Throttle-Valve ultimately override and downshift?

I've got the one worm-track in the VB blocked so as to allow locking the converter in 3rd or 2nd if it matters.


(I've gone a built a Frankisteen trans and might finally be able to properly dial-in the still newish triples).

Thanks guys.

Ground out the OD wire right at the transmission instead of grounding it after the ECU. It will do exactly that.

Put it on a switch right next to the lockup switch.

That's how mine was. I put a latching computer power switch not to my OD on/off for the tcc. I tapped the wiring at the fender though.
Use a good heat shrinking splice to prevent corrosion
