Gear Selection Cable

This is a fresh scratch your head post that I never heard before. Over Covid/winter I decided to freshen up the 64 Savoy. I bought new speedo cable and both tranny cables from the guys at A&A. Got the new cables and installed them no sweat. Checked them out and everything was a go. Fast forward two months and came home backed the car off the trailer put the car in park and went to move the trailer so far so good. I come back to put the car in the garage so I select drive and nothing messed around to see WTF and still nothing, my driveway is kinda steep so no way to get it in the Garage. Called HAGGERTY and after a good laugh they sent a rollback to get it put away. Next day I get it up on the rack and pull the gear selection cable out and it is stuck in the housing and it will not slide freely.

I call and talk to A&A and Rick says that it probably welded it self to the inside of the housing and how were my grounds on the car? So after a long pause they said they would send me out a new cable so all good with that part of the story.

So I called a good buddy big time NHRA and MOPAR racer and collector. He tell me that everyone of his cars along with the normal ground straps which I have also, he always grounds the tail shaft mount of the transmission to the crossmember. So I did also just in case A&A was right.

Never in over 60 years messing with this stuff have I ever heard that happening to cable shift cars.
It does make sense. I know the local exhaust shop disconnects the battery and grounds everything before he welds.
Thanks !

IT Happens...did an engine swap in a Camaro once and the negative battery cable was loose and the shift cable did the same thing. Electricity will take the path of least resistance in this case your shift cable

I guess anything can happen!
