Doesnt sound like a trans problem. If you start it up in park and it idles way high and requires throttle to keep alive, something else is wrong.

The hub change would be unrelated, but the spark plug change could be or it could just be bad luck. Are you sure you sure none of the plug wires got damaged during removal? Are you sure none of the new plugs have cracked ceramic? Gaps all ok? Did you unplug / disconnect anything else?
