Did i damage my 727

I had exactly the same problems with mine until I got the 36 inch cable from B&M.
It doesn’t go farther forward than the bell housing an makes near a perfect half circle from the shifter to the trans linkage.
It was called Heavy Duty Race cable and is a lot tougher with less deflection.
It feels WAY more solid when shifting also.
I did have to make a spacer ring on my Hurst Pro Matic cable pin on the shifter, but everything else was the same.
Trans is probably just fine, as I doubt you were going fast enough to hurt anything.
Those TF’s are tough as hell.
I have read good things on that cable and shorter does make sense so I ordered the size and type your referring to, of course mine is a TCI fast gate shifter but they all really similar so I'll try it and report back, I also am taking this opportunity to upgrade tranny pan as well so I will report back. Also what size hole u have cut in your floor 1"? Also I know it's a lot to ask but do u have any pictures ? Thanks for the help as well
