Re: 1970 auto shifter broke!

Back when I still had an auto tranny (TH350), my column shifter became harder and harder to move. One day I forced it and the ball stud broke off the end. I bought a new lever and installed it, but it didn't solve the hard shifting issue. Turns out, the old grease inside the steering column had just hardened up to the point that it was causing a lot of drag on the internal column linkage. I simply sprayed a bunch of my favorite penetrating oil down the column, let it soak, hit it again, cleaned up the excess oil that ran out the other end, installed new shift lever and cycled it through the gears a couple of times. Totally freed up the internal column linkage and it shifted into gear a smooth as silk.
