give hawks third gen parts a call I could not find one for the life of me until I remembered them. They have them. Make sure you get the stock 4l60e one if your using the stock style shifter since the little ball that the shifter linkage snaps onto is bigger on the 4l60e than the 4l80e. Make sure you tell them that when you talk to them.
