Introductions, New Member, Floor Shift Conversion

Hello group, my name is Doug, I’m from south western Pa, near Butler , the original home of bantam.
I’m restoring a 1966 tux, originally sierra blue, missing a lot of the tux parts, but building to look like a stock universal. I bought this one in Waterloo, Iowa, it came with an Indiana title.
No speedo, but the 2014 title date shows 35000 miles at that time, and based on parts wear, I think it’s original. I think it became a donor vehicle about that time. It was missing quite a few parts when I got it. Nonetheless, I am trying to return it to a stock configuration and am attempting to find as many original parts as is practical.
Since I am converting to floor shift, I would like to hear opinions about the process and all the parts that need changing, is this as simple as pulling the existing shift forks and bolting on a new shift plate?

 

Yep. Just plug the side "ports" and install the floor shifter. On a CJ5, you have a large enough floor plate that you can do that without pulling anything else.

 

Welcome from Michigan.

 

Welcome from idaho!

 

Can you pull the side shift forks without transmission disassembly?

 

Thinking about that, you are correct. There will not be room to remove the side shift forks with the mainshaft still in-place.

 

No, you'll have to remove the forks, shift rods, and detent pills/springs. You will also have to plug the shaft holes in the housing as well. You should be able to use the old shift shafts for that.
You may be better off finding a donor trans or a rebuild, at least to get a top shift casing. You're going to want to look in the transmission anyway. If it is a V6, stock should be a T86. Since a lot of these have been converted to a T90, it would be good to know.

 

I have a T90 top and shifter.

 

The trans is already on my bench, and I have a complete shift plate assembly.
Its original to the jeep, pretty crusty, and I am going through it totally.
Original shift linkage is long gone, engine is an f134.
I was planning on making some proper plugs from brass stock on the lathe.

 

I have Tuxes with the column shift T90. These are the T90C, meaning they have a different (lower) 1st gear. You can convert to a cane shift, but this requires disassembling the transmission so you can remove the small side shift forks and plug the holes. They remove from the inside. Save the old parts so you, or someone else, can convert it back. Those side-shift T90’s are pretty hard to find when restoring an F-134 Tux. Same with the column shift linkage; don’t discard it!
You might be better off finding a regular cane shift T90 that are very common.

Thread hijack alert!!

Will a T15 (or T14) bolt up in place of a T86 or T90? Yes, I’m displaying my ignorance right here in front of you all.

Those are newer (and stronger?) than the oldies, and maybe even easier to find.

Behind what engine?

 

Whichever Doug - the thread starter - has. I asked because I have a T14 with some good parts (not the input shaft), and, I presume, a T15 behind a 304 in the ‘72 donormobile. Either should be more robust than the T86…

Both were/are ahead of Dana 20 transfer cases.

Agreed, AFAIK the T14 & T15 are not easily adapted to the 4 cyl. T98 4 speed would be awesome but they're tough to find, and lots of other modifications needed.

 

When I bought my Tux the previous owner wanted the plow back, he gave all the parts from a 64 doner Jeep he had for the plow. I got a blown 134 F the trans, transfer case, and some body parts. I rebuilt the floor shift trans, and put a V6 large Hole transfer case in it, after putting an up grade in it. I would keep the Column shift trans, and find a floor shift T 90 and keep the column shift as is for barging with. I have my column shift the way it was. I had a DJ with a column shift at one time, they are still around. Good Luck what ever you do.
