Anyone hear of this being done or has done it?
Just curious, playing with the idea...

Just a thought - SRT 10 Manual Tranny in a Hemi?

I'm looking into doing this swap. I have a 4wd so I'm thinking about the getrag 238. I see a lot of people doubting it will hold up against the hemi, but it seems like there are a few jeep guys that are saying it is fine. I think if I take my time finding used parts, it shouldn't be too expensive. I considered the nv4500 but they are more expensive and I think I would need a different transfer case among other things.
The G238s can be picked up pretty cheap. I think I'm gonna grab one from a 2005 Ram. It should bolt up to my transfer case and hemi without any fabrication. Hopefully I can find someone parting out a 2005 truck so I can get the driveshafts and anything else they have.
I'm in MD so I'm not concerned about emissions. After the initial inspection you don't have to keep taking it in.
I'm at least subscribing to this thread to keep up on the good info!

What did the getrag238 come in? Is that the trans that is in the half ton 3.7/4.7 trucks? It depends on how hard you beat on it, like anything else.
It might not be a bad swap although probably not the best choice behind a hemi but it might work out. I've driven one and it seems like an OK shifting trans. IDK about behind a hemi
If you want bulletproof you could do the G56. It's a good trans but you'd still have to worry about the t case and all that good stuff

If I recall the nv5600 was in the 2500's then replaced by the G56. I belive the nv4500 was replaced by the NV5600 and the NV3500 was in the 1500's before the G238.
Easiest in terms of install for clutch/bellhousing, yes. Gearing is all wrong for light duty truck.

Yeah, I think Pockets has it right. Although I think they put the nv5600 in the 3500 trucks and nv4500 in the 2500 trucks before the g56.
In 2005, they replaced the nv3500 with the getrag 238 in the 1500s. They also still used the 241 transfer case with manual shift (that's what I have in my 2002). That's why I'm thinking I can get the driveshaft parts from a 2005 truck. I'll probably try to find a new performance clutch setup though.
G238 certainly not bulletproof for the hemi, but I think it will be ok. I don't race my truck, just like to romp on it here and there. I haul some wood but not a lot of heavy towing. I would gain 300 rpms (in 6th gear) with the g238...not the best for highway mileage, but I have another vehicle for long trips.

The NV4500 was used in chevy and Dodge 3/4 and 1 ton trucks since the late 80s until it was replaced by the 6 speed version (NV5600)of it in 2002 or so. The G56 replaced the 5600 in 2005
The gearing on the G56 isn't bad as long as you skip first gear. It's low in a cummins but you have half the RPM range of a gas motor. I would think that 31" tires with a 3.55 rear end and a G56 wouldn't be a bad combo. Still not as smooth or fast shifting as a T56 but it would still be cool.
Also, the new G56s have higher gears than the 2005/2006 G56s so that would help some also
Ok I ran the numbers, with 31" tires, 3.55 and a 3.5:1 first gear you will be at about the same RPM in first gear as our transmission with 4.10 gears. Not too bad

I would say the easiest would be the 5600 or the G56 since we know they bolt right up to the hemi and we can get stock parts for them if we needed
The 5600 is a direct replacement for the 4500, clutch and everything is the same. They might have different lengths though but it should be just as easy to install
I'd bet that you could probably do an aftermerket set up cheaper than a stock set up (G56/5600)

I've been thinking more about the manual swap lately so I thought I would revive the thread. I've been fighting myself about nv4500 vs getrag 238. The nv4500 will handle more power so it would provide a little growing room. I think my np241D transfer case will work if I replace the input shaft from the 23 spline to the 29 spline. From that point, I'd be shortening/lengthening draft shafts.
I think I'm sticking with the getrag 238. Looking at the dealer part catalogs, the 2005 truck with g238 used the exact same driveshafts as my truck. I know the 2005 1500 offered the manual 241D transfer case, I just don't know for sure that it came with the getrag 238.
I know the trans will bolt to my hemi. Does anyone know if the g238 came with a np241 transfer case? If so, I'm going to do this.

I'm not sure which t case they came with but I would assume it's the same. I know that you can take an np205 or an np208 and mate it to an NV4500 but I think the NV4500s came with 241s like you have. So, it appears that they are pretty interchangeable with the exception of the manual vs auto spline counts.

I know the NV4500 is very reliable but its no speed shifters dream lol never tried a 238

This is a little outside the box. But in many ways has advantages.

The NV4500 isn't as quick as a T56 or anything but my buddy has a 99 cummins that ran a 15.2 with just a programmer with an NV4500 and the clutch slipped in every gear. It's easily a low 14 second truck with the little mods it has. He can shift the crap out of it. There are people running 12s maybe even faster with NV4500s
Again, it wouldn't be my choice if I was just shooting for speed but it sure is strong and it's still better than our stupid autos
