I guess that's the shorter question I should have asked - how does the trans behave in limp-home mode (i.e. when the CG fuse is blown)? Can it be fully manual-shifted or is it what I'm seeing? Because that's essentially the mode it's in. I agree - in the current mode, the solenoids are in 3rd gear but the hydraulics are in 1, 2, or 3 depending on the lever. Maybe the hydraulics won't over-ride 3rd all the way to 1st by design, to avoid overspeeding it, for example by pulling the lever in to 1st gear at speed. Makes sense, I just would like to know how it is supposed to work.
