Then you know how much it costs. These transmissions can do very well behind a stock motor and sometimes they don't. To build them...all depends on what you'd like to do. An input shaft by itself is $425-450 for one that you should never break.

You could make your trans HD by swapping the diff, diff cover and right axle. Then you'd have 3.29 gearing and would want to reprogram the pcm for that change and the difference of the fuel pump speeds etc.
