If the 700R4 is anything like the 200-4R, it does NOT have a kickdown, it has a TV cable. They might look the same, but:

Kickdown - Just tells the trans when it's time to upshift
TV - Does kickdown PLUS it controls the throttle valve line pressures

So if it gets out of adjustment, it can burn up the trans. I'd get that set and adjusted before you drive it anywhere. Worst case "tighten" it so it gets pulled more, it's better to err on the side of too much rather than too little. If you have it too tight, it'll upshift late (hold gears longer than you want) but the pressures will be safe.

I'm not a transmission guy, so someone might be along shortly to correct my mistakes...
