I polished both the selector and kickdown shafts.

make sure to take pictures of everything assembled before you take it apart.

Especially the selector comb and note what position it's in so you put it back in the same gear.

I put a little grease on the OD of the shaft so it didn't tear or mess up the seal. The seal had some grease in it already.

Thanks for the great pictures and tips. I am looking forward to starting it, but it needs to warm up first.

I used this durring wheel to polish the surface.

Love these. I leave this on my bench grinder and a brillo flapper wheel.

I use it for trim prep for polishing. Speeds up taking out deeper scratches.

This is like my flapper wheel. I think there's less expensive versions out there

This is where many fail and wonder why it still leaks

I have exactly the same setup but use a lathe with strips of various grit sandpaper. One would need to be careful not to create flat spots with the wheels or have the wheel grab it and sling it

You should have a mile of room to change it without removing the pan. I did one in my 70 Challenger by picking it out with a small straight screwdriver, then after polishing the shaft with a scotchbrite pad, I used a C clamp and a deep socket same size as the seal and pushed back in. It worked great!
