I have an 02 silverado 4wd and lost the tranny at 115k. Had it rebuild and installed it myself. I hooked everything back up and added 5 quarts per tanny shop request and started it. I was letting it warm up and added another 2 quarts then went through all the gears while sitting in the driveway. When it went into 1st it suck there and now I cant even start the truck because it is in gear. The shift lever moves but the tranny will not shift out of gear. Please help this is a nightmare for me.
