3 on the tree to a 4 on the tree

Post #1 by Blairsville Ed » Mon Apr 29, 2019 8:23 am

1968 F100,240, 3 speed column shift, 3.70 rear gear

I’m currently still nostalgic concerning my column shift 3 speed. I’ve already shortened the column and have added power steering, but the 3 speed winds up to 3000 rpm at 70 mph. The 3 speed with added overdrive are rare and expensive. I found one in Chattanooga for $750.
After searching for a few weeks I found a 4 speed with overdrive, cast iron, side shift for a good price.
Adapting it to a column shift is now in progress.
First, I did a rebuild on the unit and while I had it torn down I needed to find a way to change the output shaft to a fixed yoke. My truck is a long bed with a 2 piece driveshaft and a center support bearing. I figured that Ford must have had a good reason to use a fixed yoke at the transmission so I needed a shoulder on the output shaft to tighten the yoke against. My solution was to turn a groove on the spline and fit it with a collar. I machine a collar to size then I cut it with a hack saw, opened it up, and squeezed it into the groove that I machined into the shaft. I then welded the collar back together. I then drilled and tapped the end and inserted a stud.
I got a surplus T handle Morse cable on eBay to engage reverse and next I’ll need to make the shifter levers. The old ones will not work with the shift rods.
I’ll need to shorten the driveshaft as well.

If anyone has done this or if you have some ideas that may help please post them.

I have had the trans in for a few weeks now and it is nice to have the OD gear. The 3.25 first gear has been helpful to pull the pontoon boat up the ramp.
The column shift linkage took a few tries to find the right shape and length. The 1-2 rod I used was the original R-1 rod on the 3 speed. It worked without any modifications since the 1-2 lever was in the same location as the R-1 on the 3 speed.
The 3-4 rod had to be made from 3/8 rod. I had to thread one end to 5/16-24 and weld a right angle on the other end. I also switch the trans ends to a heim joint.
The cable for reverse was fairly straight forward. I made all 3 levers from 1/4 x 1.
The 3-4 lever had to be shorter than the 1-2 lever since the 3-4 lever has to point up.

If you find yourself installing one these transmissions, be aware that the speedometer gear may or may not be a right hand gear. The internet posters indicate that if the Speedometer cable enters the transmission on the drivers side, then it’s a right hand gear set. In my case that was not correct. My cable does enter the trans on the drivers side but it was a left hand gear set. The 3 speed that was originally in the truck also had the speedometer cable on the drivers side but it was a right hand gear set. The difference was the original 3 speed trans speedometer gear meshed with the transmission gear on the top of the gear and the 4 speed OD trans speedometer gear meshes on the bottom of the trans gear.

Quad on the rod. Cut me a switch....


Very nice work. Our L200 Mitsubishi foward control van had something similar.

The early column shift Mark I Cortina 1200/1500s did too. Like the Saab 96.

That is totally awesome. A lot of people of talked about that but I’ve never actually seen it done.

Great work!

What's on the other end of the reverse cable?

The ONLY safety device we need is a 6" sharpened steel spike bolted to the center of the steering wheel of EVERY vehicle.

Inside the cab, the cable is currently mounted to the bottom of the dash, on the left side of the column. It is a “T” handle that pulls out and rotates 90 degrees to lock. During the rebuilding process I replaced the reverse detent spring with a lighter tension spring since the locking cable would hold the reverse gear in and make it easier for a cable to operate. In the future, I hope to mount the cable in the dash by moving the wiper switch to the right side of the column and I’ll be trying to make a bezel with the word “ reversed “ embossed into it.
I’ll post a pic later today.

This is a pull and turn- to - lock cable.
I hope to create a dash bezel and install the cable in the hole where the wiper switch is. Then move the wiper switch to the right side of the steering column.

If I saw this before my NV3550 swap I probably would have gone with this trans. My original goal was to just get the od gear for more civilized highway use. I do enjoy having a close ratio 1-4 to go with the od 5th but the 250 has enough torque to make this toploader 1-3 gears perfectly useable. And probably would have saved some money plus I always liked the column shift.
