Please Help, brother's shifter stuck ('67 F250 automatic)
My brother's shift selector doesn't display what gear...he seems to have to "push up" to get it to start. Can't seem to find any of the gears but 2nd, and doesn't want to drive to my house with out it shifting. He's now stuck at the ferry ready to load!
Any clue what causes these issues? He has a '67 F250 with a 390, and not sure if C4 or C6.

Seems like his selections are all askew... I am not sure if he can feel all the detents. I think some of them "hang off" the edge for want of a better phrase. He was able to limp it home and swap vehicles, so at least he isn't stuck any more.
Thanks for the info!

If you have to wiggle the shift lever to get the truck to start in Park or Neutral, the problem lies with the Neutral Safety Switch, which is located on the bottom of the steering column.
If the truck is not shifting properly, it could be caused by the Modulator Valve, located on the transmission.
If this problem suddenly occured, there is a rubber vacuum hose that connects to a nipple on the valve. The hose may be cracked, kinked or has come loose.
The only V8 available in 1967 F100/350's was the 352 2V. The only A/T available with this engine was the MX Cruise-O-Matic.
The 390 (and 360) and the C6 were not available in F100/350's until 1968.
The only difference between D1 and D2 is, one starts out in second, the other starts out in first. You can drive in either range.

Well I had a chance to talk at length with my brother about the shift issues and it seems very bizarre to me, but perhaps you have seen something like this before:
The first line is the position of the shifter and indicator on the steering column. The second line is what gear the truck is actually in. He can feel the detents and can feel it going into gear. You can see it doesn't quite line up, but this is where he is finding the gears:
...P...R...N...D...2...1...
.....2...1...P...R...N......
"Drive" is not available in the range of motion. Seems like it "hangs off" either end.
To top it off, the neutral safety switch seems to be functioning according to its real intended position, which means the truck ends up starting in gear (selector says park, tranny says near 2nd).
This came on suddenly. It wasn't like the linkage was taken off and then put on incorrectly, it was functioning as designed (save for a slight missalignment of the selector with the gear, that resulted in having to push up slightly for the neutral saftey switch).
I hope this makes his problem more clear than I originally explained it.
ME.
Thanks, experts!

When you put the shift lever into Park, does it pop out of Park into Reverse?
A/T trucks are designed to start in Park and Neutral, nothing else.
The NSS is controlled by the spring steel NSS selector lever ( looks like this: )--- ). It snaps onto the shift tube through a hole in the mast jacket (steering column outer shroud).
This lever has a knife blade pointed end where it fits into the NSS. The knife blade end is notorious for snapping off. The lever can lose tensile strength, then it falls off the shift tube.
If the selector lever is defective or missing, the truck can be started in any gear.

This is the NSS Numberdummy mentioned.
This one has been removed and messed with because the tab broke off it.

THANKS, GUYS!
This is all good info... I think my brother will be relieved to discover that the problems seem to be quite fixable and not uncommon. I will help him track down the right parts (with your kind assistance above!) and see what we can do to get him back up and running right.

Oh, and Bill, no, it doesn't seem to pop into reverse from Park. It just seems weird that 2 and 1 show up to the LEFT of Reverse. Everything is in the right order, but jumps off the end and starts over. I am still trying to wrap my brain around that...

What happens to it: People put the truck into Park before setting the parking brake...this can cause the truck to roll...just enough...that the parking pawl inside the trans locks up tight.
Now...the shift lever has to be YANKED out of Park to free up the parking pawl, and sooner or later, the individual gate between Park and Reverse snaps off.
Another problem: The tab on the shift lever wears down, the gates wear down, sooner or later you have no idea what gear you are in, as the shift lever flops around.
One more: The pot metal shift collar connects to the shift tube inside the column with a bridge...sooner or later the bridge cracks in two, now you aren't going anywhere.
