Did i damage my 727

So I dropped the pan saw some material and what looks like to be rust(this transmission was sitting for a few years) maybe not sure and metallic I'll post pictures. So I got a replacement tci 5ft cable and the b and m super duty 3ft cable . Worked on the trying to get the 3ft cable to work almost all night but no luck due it has to make a sharp curve and just won't bend that much. Maybe I can see if I can return it to summit or just use the replacement 5ft and route it out the passenger side around orMor a 4 foot would work since all that's needed is just a hair more.
