So on my '66 520 there seems to be a lot of play in the shifter (Not sure which transmission it is, kinda new here) I'm pretty sure its the 4 speed manual.

 

Its just kinda hard to find 3rd, wondering if there's anything I can do to tighten it up?

First does the transmission have a plate bolted on the bottom or is it rounded on the bottom?

Is the transmission in the truck or out of the truck?

Should be this one above.

The two rubber cones marked #8 top picture can be clamped down more tightly if you add washers below #7 and above #5 and tighten nut #4. This is likely the most sloppy fit area. The nut can only be tightened down so far so if the cones are really loose tightening doesn't help. Use washers for spacers. It's no wonder this shifter style is also known as the 'Monkey Motion' shifter.

 

In the picture above you can see slack on the pin marked #17 that a suitable washer could fill.

This area can also wear and cause side to side movement of the shifter but no actual movement of the striker rod that needs to turn. The striker rod also has to move forward and back so the fit cannot be too tight either. Again if severely worn a thin washer can be placed on that pin (#19) that is held on by an E clip (#19) on each side.

Wow thanks! I'll def look at this as soon as it warms up. Low of 8° today  :hyper:

 

I'll also let you know Wayno which one it is when I clear some snow out.

Mike covered everything you need to know right now with photos which helps a lot, early transmissions have the rounded bottom.

Anybody know the technical name/part number for #37 in the diagram mike posted? Mine is broken and I'm trying to figure out where to get one, or even what to call it as I'm talking to people. Thanks in advance.

Yes I do, it's called the control arm.

 

I don't know how you would remove it without taking the transmission apart so the striking rod could be pulled forward and out of it. If you have the pieces have it TIG welded in place.

What part of it broke... like mike said you can have it welded... but becareful I broke mine also... and I can almost bet we made the same mistake.... find someone really good at tig welding. I was told the part is pot metal and tricky to weld...
i brough him the whole transmission, didn't have to disassemble....
I broke the ear where the pin goes... so he ended up stacking the welds and rebuilding it.. after welding i had to reshape and drill the hole, i also use a bolt and lock nut instead of the pin, and a bushing in the shifter to fit the bolt...

Seems like you should be able to find another transmission from someone in the area you live, it is hard to give them transmissions away, everyone wants 5 speeds so the 4 speeds get scrapped, there is this story I have heard in the past about Hainz, he put two 4 speeds out in front of his house with a free sign on them, when he woke up the next morning and there were 3 of them out there in front of his house.

There are a lot of guys up there between Olympia and Everett that have converted over to 5 speeds, one should be able to buy a 4 speed for cheap.
