Has anyone ever seen one of these?

Very unique, what is the plan?

Just saw one the other day, Constantine has one, neat looking piece and light weight.

Nice piece. I’ve thought about doing something a bit similar with a Laycock overdrive.

I've never seem or heard of one in 55 years of' T'ing.
This forum is full of surprises.
Thanks
Rich

Joe is correct. I have one that needs a rebuild. You could say it's a thinking man's Model T transmission (so Gary Norton in MI, it's certainly not for you monkey boy).
Here's some pics.

I would like to buy one. If anyone has one to sell, please let me know.

Thanks

I had one in my 13 speedster . Worked great but you can get it in neutral and it won't go back in until stopped . I did that on first ride put it in a ditch only hurting my pride .

I’ve got the TT version going in my truck. Just painted it two nights ago. I’d also like to find another for parts just to have lying around.

Here it is all painted up.

And before.

I have a TT with a Twin-High Hi Lo type and would like to know more about it, like are parts available for it? and those with any experience with one is it noisey and do they shift easily? I bought the truck because of it and haven't gotten it running. I have been keeping my eyes open for doors, if I can find 4 doors I want to build a crew cab.

Note that the Twin-High Hi Lo type tranny was also made for the worm drive AA.

I’ve seen two slightly versions of the one I have. Assuming yours is one of those, no parts are not available. If you’re good with a micrometer, you should be able to match up the bearings with new replacements. Mine were in nice shape and the races looked almost brand new. It was just all sludged up. if you plan to go through it, here’s what I did. Separating the unit from the torque tube and driveshaft is a Royal PITA. You just have to remove the u joint pin and u joint, take out the two clamping bolts from the front of the trans. Slide the torque tube off the drive shaft. There is then a pin holding the drive shaft to the input of the trans that took me a solid hour and a half to get that out alone. It’s smooth sailing from there. Six bolts are holding it to the rear axel like a normal torque tube. The shifters come out without much fuss. There ten 3/8” bolts holding the case together. Four are 1”, four are 4” and two are 4-1/2” all should have a 9/16” head. Now is where I suggest taking pictures and remembering orientation. One slider pulls out of the back no problem. Once it’s split into thirds, you can do the bulk of your cleaning with brake cleaner to knock most of the gunk off. Then the front has a 1-1/16 nut with a cotter pin. Once that’s removed, start taking pictures because it can get to be a whole lot real quick. Everything should slide apart from there. After that, throw it back together, make some gaskets, squirt some paint for effect and you’re golden. Time consuming but probably worth the peace of mind that it’s solid. Mine shifted pretty easy but I also only shifted it while turning the motor over by hand. Any noise would probably be attributed to bearing/gear wear. Like I said before, the guts in mine are pretty nice so I don’t expect much problem.

Thanks Constintine and Brad, this project is still a ways down the list but glad to know more about it. Dennis

That's a really impressive accessory! Looks like it was well engineered!

I want one if anyone has one to sell.

Thanks
