tranny shifts hard.does any one know who makes the repair kit for the 4l60 tranny for the valve body, and which valve causes the tranny to shift hard from 1-2 pluss shudder on take off.thanks

I have the same problem. Here are a couple of links that should help. You will need to buy the reamer ($100). Which one depends on whether the valve body is remanufactored or not. In the second link, scroll down to interactive reaming instructions.
