Will GM 200r4 work with factory floor shift location?

What's your max stall on your converter??? If you're running a lock up (which I think you are) you don't want to be cruising at a speed that will cause the converter to be kicking in and out???
That's why I went with a non lock up...that, and the fact that I didn't want extra wires and lock up switch and positive release switch (vacuum and brake pedal switch).
You gotta figure this stuff out before you go too far!!!

Thanks for the heads up, but I think PoisonDart74 has it right. My max stall on the converter is designed to be 3000 rpm. The system I'm using only uses one 12v wire. There are no solenoids or vacuum switches to deal with. It's either on or off, but only in 4th gear. Once it down shifts into 3 or below, it automatically disengages the lock-up.

I'm going to use a small button mounted on the B&M shifter handle to lock it up or leave it off. There are no other parts or switches to deal with. It makes it simple.

I know the 500 and 518's require all that extra control stuff.
