Is that from the interwebs or do you have all 3 and can take more photos? If so I'd really appreciate it!

Wow, the NAG looks like it’ll fit without to much tunnel surgery. If someone would do a kit for these transmissions for retrofits I think they’d sell

Darius had to raise his tunnel in a B body per his build thread, didn't look terrible. I'd like to see more photos and measurements to gauge the fit.

I had someone send me the pic. I've had it a long time. I've talked to a person who put the NAG1 in an ebody, he said all he had to do was do some bending of the dipstick tube to get it to fit.

A buddy built a 71 Challenger Convertible with a 392 and a NAG1 trans.

Here's a link to his website with pics on the build. http://www.lotsapins.com/Hemiswap/pics.htm

The crossmember is further back on an e-body vs b-body... that makes a world of difference in a 518 swap also. I imagine it's the same deal for these transmissions.

going back through cbodydrydock.com threads I found this pic showing tunnel mods when running the 545RFE. Now I want the dimensions of the 545RFE as well to compare :P

I was changing the oil in my 2012 charger this weekend with the 3.6 and TF8. I couldn't get any good measurements of the TF8 in the car but it's near 30" bellhousing to mount and at the mount still seemed to be 9" tall (9" diameter). It's a big dude. The tunnel in the car looks huge from the underside.

Good find on the pics! Yes, the 8 speed is huge. There is a guy on Facebook putting one in a car...let me see if I can find the info for you.

Joel Applegate is his name. He frequents the page G3 Hemi Swap. Here is a picture of his swap, but doesnt show you much. There are two sizes of the 8 speed, the "90" and the "70". The "70" is smaller but doesn't handle as much hp.

The page is called G3 Hemi Swap. I don't know the details on a controller or if he is using all the factory stuff. I know people are working on it to try and crack the code.

Just a thought, I was under my 93 Mersedes 300 SD and noticed that trans looks just like the Nag One. Bell bolts on just like the Nag plus this trans has a shifter and is modulated by vacuum. This is a 4 speed but the gas engines are 5 speed. No computers, no electronics.
If they s would work, what an option.

hmmm, I know they made them for a long time, but is there actually a hydro/vac controlled 5spd version that handles any real torque? That would be really intriguing if you can bolt on a hemi bell...

wikipedia only says this

722.5 — 5-speed (hydraulically controlled 4-speed with additional electrically controlled 5th overdrive gear)

no actual page for it, but a page for the 4spd before and the 722.6, of course :P

google isn't being my friend, can't find much about the trans, it's construction, or torque rating

this one does not have a bolt on bell and is much skinnier than a .6

this might be worth $10 tho lol

I asked Russell Drake about them and he said the 722.5 is weak, only went behind v6.

The S class cars will have the better one. Mines a turbo 6 and the gas is a straight 6 and V8.
The lowly PG wasn't much before the aftermarket got there hands on it either.

so what do you do with that clunky mercedes shifter? looks like it would be hard to cut down to fit into a stock console.....i am leaning toward a 46HD where you can use the stock shifter and console-----with this much power i cant see the need for a 6 or 8 speed unless its is just to brag about all the gears and how cool it is.........
