I sent my pcm to sia for a trans issue I was having. harsh 1st to 2nd and a weird 2nd to 3rd shift thing going on. After reading threads about this on lvc I finally sent my pcm out to get fixed. SIA said they changed out the pressure control chips in the pcm. Long story short my trans is working great , wish I would of sent it out sooner. I put 3000 miles on it driving it the way it was. After 50 miles its working perfect.
