Replacement for the Peugeot
As I get further in my restoration of my '87, I'm getting closer to replacing the Peugeot BA10/5 it came with. As a light-duty transmission, the first one gave me quite a few years. However, as we all know, it isn't meant for what we use the Jeep for, and there is no point to throw money at it.
In mind for its replacement are the Aisin AX-15, and the New Venture NV3550. I had mostly considered the AX-15; however, from more research, I'm leaning now toward the NV3550 as it has a lower first gear, and the (nearly) same overdrive. It is considered to have equivalent strength, input and output, as Aisin's transmission. While communicating with Novak Conversions, they do not sell the 3550, so I would have to outsource it.
What are your thoughts about transmission choice, and why?

Is first gear that much lower?
AX15 could be sourced used with all the goodies to install it....
Keep in mind your transfer case is likely 21 spline

A bell housing from a '89, for example, would allow me to use my CPS, but limit me to an internal slave/throughout bearing system, similar to what I have now. A later model bell housing uses the external slave cylinder, but I can't confirm the CPS will be accepted in the newer housing. Novak's bell housing gives me the best of both worlds.
The Peugeot uses a unique setup for the transfer case shift linkage, so unless I get all the donor parts the first time, I'll be trying to figure out how to fabricate linkage. On the other hand, Novak has a really nice system for the XJs; much better than the original in my opinion.
Another obstacle, I believe, is a new transmission mount and moving the cross member (again, the Puegeot is about 4-5 inches forward of where the AX-15 is on later models. That means my skid plate is too short. Novak has an adapter instead.
Lastly, regardless, I'll have to re-plumb the slave cylinder line to match a new external slave cylinder. I might have to replace the mating end anyway if I used an internal slave assuming it doesn't match the threads/configuration of what's on the BA10/5.
The gear ratios of the two transmissions are as follows:
NV3550
1= 4.01
2= 2.33
3= 1.39
4= 1.00
5= 0.78
AX-15
1= 3.83
2= 2.33
3= 1.44
4= 1.00
5= 0.79
If I source an NV3550, I believe I can have 5th gear changed to .73 as used in some of the Dodge models. I haven't confirmed this yet. But, it would lower my highway RPMs by bout 200+/- considering I have 4.88 axle gears and 235/80-17 tires. That is secondary to the first gear preference.
What's your way of thinking?

I thought about using used parts out of a later model. But, given the fact that the transmission would need rebuilding eventually with respect to the mileage of the donor and how its owner treated it, I might as well start out new. Everything else in the engine bay, quite literally, is new. Yes, the input shaft needs replacing to a 23-spline shaft, and mine was rebuilt not that long ago. And... I know its history and how the owner treated it!

I run a NV 3550 and 231 transfer from 2000 TJ .Cps works fine. I run a external slave and master from a 94 xj. Other than front yoke being clocked a little higher and its shifter is taller. It was direct bolt in. Crossmember holes in frame rails were there and all ready taped . I just chased them with a tap and was good to go. Tansfer case linkage bracket did have to be altered some but it was pretty basic.

Sorry for the delay...
I'd like to hear your entire process, like what you used from what vehicles as you partially mentioned above. I do usually consider used and/or refurbished items, depending on what it is. In this case, a transmission with a lot of mileage isn't what I'm looking for; however, a rebuilt unit I would consider. As far as the miscellaneous items, I've read a lot of "stories" from others about not having everything from the donor vehicle/vehicles to complete the substitution. That's why I was considering Novak- they provide everything necessary.

Got a buddy with the NV in his YJ. The lower first is killer in low range, its stronger, and its more fun to drive on the street. All around win if you can find one for reasonable money.
