howdy fellas,

ive got a 9 bolt 3.27 posi rear... My problem is when shifting from park to reverse i get a clunk, park to drive, same goes for the downshift from 3rd to 2nd. I've replaced the trans. mount, i tried to rotate the driveshaft and it seems tight. So im assuming the u-joints are good. My next guess would be backlash on the rear?? I had a shop replace the pinon seal on the rear and im not real sure they got the backlash set right. How would I go about adjusting this? I've heard that on posi rears you have to mic everything in, doesnt sound like much fun :\

thanx in advance,
matt
