    I don't remember each shift honestly, I don't pay much attention to it. OD in the Towncar is about 45 though and the Mark VII is closer to 40. The Towncar is probably a wee bit late if I'm being honest. When I got both of them the Towncar was OD about 32, and the Mark VII was around 35. Neither were thrilled about it, the engine was obviously lugging and downshifts were slow.

      That sounds about where I was. I’ll test drive it and see how it does. If it’s too tight then I’ll as just a bit of slack to see how it acts.

        Pulled it to WOT and there’s about a 1inch of space. And last guy most definitely fucked with the throttle plate, pretty evident because obviously the screw is broken and how much it is open compared to the one I pulled…

        Edit: had the throttle cable unhooked when I put the cable on and corrected my mistake

          Shifts pretty soft now, goes into 2nd around 15, 3rd around 35 and I don’t think I got into OD yet, I’ll see when I get on the highway to work today. Anything sound off so far?

            If you can still feel the shifts and it's not complete mush, it ought to be fine if you don't push it hard. 1-2 shift is always a bit soft and earlier.
            The AOD is governed at 4500rpm, basically if you adjust it to WOT 2-3 shift right around there, it's pretty good too.

            Having the TV adjusted a bit too tight doesn't hurt the trans, it'll only shift harder.

              So I’ve heard. It’s just that you really don’t want it to be too loose and that’s all Im watching out for. I pushed it hard a bit to see what would happen and the shifts were still softer than before. I’ll also check my trans fluid after my drive to see if I smell anything burnt.

                OD is like 55-60

                  thats reasonable.

                  The throttle blade on these should be just barely open enough to not stick in the bore. The one off your car is way too far open. Probably why the TPS was not reading properly.
