1963 F85 shifting
Like most articles I have read I also have sloppy 1963 F85 shifting from 1-2.
If I start in S the 1-2 shift is quite good in Hydramatic style. I can then manually shift from S to D smoothly (a little sluggish into D but acceptable).
However, if I start in D when it shifts from 1, the engine revs up, then it tries to bang into 2 or D then back out back in etc.
Can this be improved by linkage adjustment?
I also have damper plate spring rattle at very slow idle ~500 rpm. Set idle speed up to ~ 850 rpm and no rattle.
I guess as long as I shift manually the transmission shouldn't get damaged any worse.
I had a Hydramatic old timer tell me to try K&W Trans X. Has anyone tried this additive?

I also have a 63 f-85 and have figured mine out. Your problem seems
to be that your TV rod is too short. Thats the adjustable rod that's connect-
ed to the carb at one end and the trans link at the other. After trying for
several attempts I finally have a smooth 1-2 shift. The length of the TV
rod is just a little over 5 1/16 inches. This length is variable beween cars,
These automatics are sensitive to this adjustment,and it doesn't take
much( 1/8 inch or less)to get the right shift point.
