94 astro wouldnt have a 4l80e. its a bit expensive to get the standalone electronics to work with a carbed motor as well.you would need to find a 3/4 ton or heavier truck to get a 4l80e. then get a standalone control unit from tci which is 1200 bucks on its own.i have had two seperate ones that refused to communicate with the laptop.real pita
