Unexplainable Transmission Stutter... help?

Don't put thin oems in the direct clutch. Unless you love r&r'ing that trans. Get a V8 drum and do it right. Your Chrysler "mechanic" seems to think that the direct clutch is engaged when placed in "D". Fraid not. And follow the clearance guidelines. Idk what "pretty tight" or "a little under" actually means; except that you are taking a lot of chances. Don't drill another hole in the spring pocket. Looks like somebody did the step #3 their own way. This valve body already had a TranGo kit; I just don't know what level; probably just RV/heavy duty. Step #4; ya just drill down to the bottom of the wall.
