Tremec 5 Speeds

Thinking out loud, is it possible to mate a Dana 18/20 to a tremec 5 speed? Asking for a friend...

 

I'd be suprised if anyone is casting an adapter for a D18/20. These transmissions have 3 shifter ports and internal rails. 5th gear is encclosed in the rear tailhousing, so this would be a complex adapter to make. Anything is possible, but a divorced transfer case would make a lot more sense if you had to use the Tremec 5-speed.
I have a TKO 600 for my '66 Chevelle.

Is the tail housing similar to the gm 4500?

 

They make a Dana 300 to T5 adapter do not think there’s one for the 18 or 20.

 

I see they make a 4x4 version. I'm guessing its not much bigger than a T18 or sm465.

I've been looking and I cant find a length of the 4wd version, but it looks long to me.

 

I was looking at these too. According to Wikipedia (take it with a gain of salt) the length of the 4x4 transmission is 19.5": Tremec TR-4050 transmission - Wikipedia

Here's one attached to a Ford Modular:


Looks like the size of a T-18 with and additional 6+ inch tail cone out the back. So the 19.5" is probably right. I would be great for a CJ6, but I'm guessing it won't fit in a CJ5.

 

But it would be great in a Commando

 

It would be awesome in a Commando!

 

What are you sticking it to?

 

I dont know....a D300 I suppose.

 

In front. Anything fun?

 

So where would one purchase this and does anyone know the price tag?

 

Not sure where to get it, but I would guess is a few grand like the car 5 speeds.

 

Looks like Advanced Adapters has them for $3700.00: 26-TR4050 : TRANSMISSION- TR4050 23SPL OUTPUT & GM INPUT | Advance Adapters

Not cheap! I'll be sticking with the T-98/Warn OD I already have.

Silver Sport Transmissions also imports them but doesn't list any prices on their web site: 4WD

 

I didn't know these things existed. With the price, it may as well not, at least for me. I couldn't justify the expense, but a neat option at least. The ratios seem like the best of both worlds.
