What RPM should the LS400 trans upshift at at WOT in sport mode?

I haven't wired the switch up yet in my swap, but the trans seems to shift at 5500 rpm into the next gear pretty conistantly. First gear seems to shift earlier.

Also, for the sport mode/power mode - is it positive triggered? It looks like it takes 5 volts to turn it on from the diagrams I've seen.

What about the kickdown switch under the pedal? power or ground triggered?

I don't want to kill my ECU, so this is some need to know stuff... LOL


Thanks!
