77 f250 have problems shift into drive
I recently got a 1977 f250 4x4 automatic transmission , and I've had it for about a month now , and three days ago I was out getting lunch and I rolled in, threw it in park ran in got my food and came out , when I started my truck up I went to throw it in drive it wouldn't go into drive , it will go into park, reverse , and neutral. I think it's the shift collar , but before I just start replacing things I wanted to get a second opinion. How I get it into drive now is I follow the steering column down to where the fire wall is and right above is this thing where I can physically push on it and wiggle my shift to get it into drive . I don't believe it's my transmission because reverse still works , maybe it linkage , maybe bushing, but I think it's the shift collar , thanks guys.

Welcome to FTE.
First of all check the fluid level!
Second, have someone cycle through the gears while observing the linkage action at the trans and action of the levers at the steering column.
Is there excessive slop? What about bent or worn linkages/bushings?
Consider changing the transmission filter it ya have never changed it.

How I get it into drive now is I follow the steering column down to where the firewall is and right above is this thing (selector lever on column) where I can physically push on it and wiggle my shift to get it into drive.

The pot metal shift collar contains an internal bridge that connects it to the shift tube. Over time, the bridge begins to crack, eventually snaps off.
Now the shift lever just "flops around," because the shift collar is no longer connected to the shift tube.
Manual control selector lever on the column uses a 'snap in' nylon bushing (EOSZ-7341-B - available from Ford) where the rod from the trans attaches.
There is another of these nylon bushings on the selector lever on the side of the trans.
Over time, these bushings crack apart/disintegrate. When this occurs, the shift lever may or may not engage all the gears.
