I just replaced my 4r75E transmission. i get everything bolted up and I fire the truck up. throw it in drive to take a spin and she was real sluggish at first, but after a few minutes everything was okay. then I get the flashing od off light. pulled a p0715 turbine shaft speed sensor malfunction. so after I get the brand new sensor in I fire the truck up and put it in neutral. I let my foot off the brake and son of a it starts driving forward put it in reverse and the engine just revs. so I take off the linkage at the selector shaft and manually put it in neutral and align the trans range sensor for neutral. put it in park, put the shift lever in park and put the linkage back on. fire it up and same thing. I have now adjusted the slack on the linkage 8 ways from sunday and same thing. the pointer on the dash was never off so I don't think its the infamous torx bolts, but at this point I am at a loss. any help would be much appreciated
