Transmission kickdown holding me from full throttle

[streetstang67]

After installing a shift kit in my c-4 transmission, the kickdown on the tranny is holding me back from reaching full throttle. I un-hooked it and let the cable dangle, and it seemed to drive okay...can I leave it like this just for a couple days? and what is wrong that won't let the kickdown lever turn to full throttle?

The cable wasn't binding or anything, it just wouldn't twist enough to go to full throttle

Sounds like when you reinstalled the valve body, it wasn't seated right with the kickdown lever. Probably have to pull it back apart. Yes, you can drive it without the kickdown cable connected but if something isn't right with the valve body placement, who knows what might happen internally.
