I picked up my car today......waited exactly 1.5 weeks for it to be fully rebuilt and installed. I drove it home about fifteen minutes and noticed right away.......no noise very quiet riding. So it seems justifiable that the previous noise was coming from in the trans. One thing I did notice is first gear shift is sluggish but it might be because everything is new and needs to be broken in. I have to drive it awhile before I say anything to the rebuilder. Other than that it shifts fine and the installed shift kit make the shift firm and crisp.
