Did you adjust the idle screw on the throttle linkage? Do the butterflies close completely?

Are you familiar with carbs or are you just guessing? The transmission is not going to make it idle high. The reason it is idling high is that air is bypassing the carb (vacuum leak). Make sure your ignition timing is not set to far advanced but I doubt that could cause a high idle like this.
