727 slipping in reverse when hot

From "WHERE" did you count the turns? I think the spec on it is to tighten the center bolt to 8 LBFT. I think the spec is given in INLB, but if I remember right it converts to about 8 LBFT. In other words, tightened "pretty good" but not stripping the thing out.
From 72 inch punds. I have torque wrench for this.
