Does not shift properly
Here is what I have:
1975 F250 - 460ci
3 speed automatic
2WD
Here is my problem:
When I shift the transmission into drive, it starts off from a stopped position like it is in second or third gear and does not shift down when pushing down on the accelerator. It has done this a few times over the past several months; eventually it will "slip" into place and it works fine for several weeks.
I have been told that there is a good chance that the shifting linkage is worn out and is preventing the transmission from shifting into gear properly. If this is the case, how do I inspect and replace the linkage? I am mechanically "able" to do many repairs on my pick up; as long as it does not involve any major work like removing the tranny, engine, etc...
I did check the arm that comes out of the side of the transmission and it seems to click into each position as it should.
Any help would be appreciated.
Thank you.

Welcome to FTE
I doubt the shift linkage is worn out, I suspect bad/missing bushings
At the bottom of the steering column underneath the hood is the gearshift selector lever. There is a snap in bushing there. If the bushing is missing, the transmission rod will flop around and not properly engage the gears. A rod goes from the selector lever to a bell crank near the carb. More bushings there. Another rod goes from the bellcrank to the manual control lever on the transmission. The same thing happens on the trans end. On the manual control lever on the left side of the case, there's another bushing. It could be missing/broken also. Bad bushings in these various locations is very common, and the usual reason why the transmission won't properly engage the correct gear.

Welcome to the site!
Please take the time to read the "Read First" thread at the top of this forum.
1) Check for the kickdown lever being off.
2) Check for a vacuum leak or faulty Trans Modulator
Note: anything about the transmission operation is best asked in the DRIVETRAIN forum
This forum is more for the discussion of the uniqueness of the 73-79 trucks.
