67 Kaiser J2000 considering a cummins

I am considering the idea of putting a cummins 24v 5.9 in my project Gladiator J2000. I wanted to get some insight or experience from anyone that might of taken the journey.

engine weight... 1160
transmision 420

HEAVY!

From reading another post on her it should work pretty good with the np205 transfer case that I already have in the truck.

5.9 is well suited for that truck
12V will be easier for wiring
VE pump motor will give you more room at firewall because of thinner adapter plate
205 will be fine
Find a J20 from '80 and up for drivers side driveshaft, more room for exhaust
What trans is 420LBS?

trans

The transmission is the Allison 545 and is attached to the engine. I am buying the complete drivetrain.

my big concern is getting the suspension right on this setup. It is currently setup for a small block chevy and this motor is twice the weight of the small block.

From a school bus?
Might want to re think the 545...too big, no overdrive, takes a lot of power to run
Way better options out there
Also the SAE adapter for the 545 won't fit without major firewall/tunnel cutting although you will have an armrest

there are some options out there for a transmission. I am considering selling it and going with a more conventional transmission for a passenger vehicle the setup was at a good price. I have spent the last 3 days researching this setup and the options that are available. Hoping to learn more as I build it.

Any experience using a dodge 47RE with the Cummins 5.9? looks like it needs a computer to be stand alone to use it.

Thoughts?

Me too. And I already had the engine and tranny (x2). It made more sense to liquidate my Cummins stuff with what people were paying.

I considered it and was just going to get a full manual valvebody, it's dirt cheap for the kit, then manually shift it with a Ratchet shifter or something like that.

The other option is converting it into a 47RH.

The NV5600 seems huge and when I look at the NV4500 it looks much smaller. I have a np205 transfer case.

Now looking for all the best way to assemble it all.

The 5600 is huge. But it actually holds up decently to a big power Cummins.

If you're not planning to make big power a NV4500 (with updated 5th gear retention) or a 47RH/RE would be fine.

I almost purchased a 47RH/RE last night but I was told there was not a good solution for a computer to operate that transmission standalone.

what did you use for a manual valve body? Seems like a nice choice in between the Alison and the 5600.

I already told you what the solution is.

The RH doesn't need a computer. It just needs a switch for converter lockup, which is controlled by the PCM in Dodge applications, but you can just do it manually and in fact a lot of the Dodge guys were doing it because converter shudder will kill those transmissions. Plus many first gen guys would swap in the 47RH because it got them a locking torque converter, so same thing they'd just put it on a switch.

The RE can be converted to a RH, or you can go FMVB, or you can use a RADesigns type shifter to control it. I honestly think FMVB is the best option for all applications. You need the converter switch still, but again that's not a big deal and if anything is ideal as many of the aftermarket shifters have a button on them for a transbrake or the like.

You also could just put the Dodge PCM in the thing and let it control it if you really want, but you need enough of the other Dodge parts to make it work. Since the original post indicates you have a 24V, you've probably got most of the parts you need.

Transgo makes a kit.

I can get the 47RE for under $300 and it is a recent pull out of a dodge truck.

I googled FMVB and found the revmax not sure what it all means. Sorry this diesel stuff is all new to me and I am trying to learn fast. Like drinking from a firehose.

If the 47re is a good solution I can pick it up this weekend and sort it out over the next few months. I just want to get the right setup started.

thanks again for your patience and knowledge!

FMVB = full manual valve body.

It's not a diesel thing. Diesel guys just realized it is a great solution to some of the problems with the automagic transmissions.

I have no idea what kits are or aren't offered, the Transgo one is cheap and does exactly what it's supposed to.

Like I said, I sold all my Cummins stuff and put an LM7 in my truck instead, so it's not like I had it all figured out.

the 47re is just an electric 727--I'd talk to either of these two guys about manual valve bodies:

Suncoast Transmission

or

The 47re is tough and simple enough to build. I've been running mine that I built myself for 12 thousand miles and my truck dyno'd at 624hp,1131tq. Gets abused daily and still pulls a 12k trailer while running cool as a kitten. I was running a full manual valve body but it got to be a pain in the ass always having to hit the switches for unlock and overdrive constantly. There is a standalone controller that is made by firepunk diesel, it's called the anteater. I've been running it for 9 thousand miles and I love it. The controller stores 3 tunes that you can switch on the fly. it will do whatever it is told and shift whenever according to the tune. If you want the converter to lock in first gear and stay locked 1st through 4th it will, it does whatever its told. The software to set up your tune is super easy to use also. Screw shifting gears, my truck was originally a 5 speed with the nv4500. I got tired of being slow so I converted to the 47re plus at my power level none of the manuals hold up long.the nv4500 and 5600 are slow shifting and don't hold up to as much abuse compared to a 47re when built right.
