Just curious, did you debate on using the (5spd) NV3500 vs the (6spd) NSG370 or was it just the NSG370 was what came along and you went with it? I would imagine for cheap gasser donors, the NV3500 is probably easier to find at a better price since it was in the 02-04 Liberty's and the NSG370 was in the 05-08, but 07 of course started a new body style that probably wouldn't help you with parts you would need for the swap?
Between the two transmissions, the NSG370 has a lower 1st gear which may not help the diesel, but it does have less gaps between all of the other the gears which probably helps keep the Diesel more in it's torque range without big jumps. The NV3500 does have an overall higher top gear, but it looks like you took care of that with the rear end change. I had a 98.5 24v Cummins with the 4500 5spd and that huge gap between 3rd & 4th gears got old using it around town. The NV5600 6spd had a much better spread and it was easier to keep the Diesel in it's torque band.
I previously drove a wrangler with the 3550 in it, it was a great transmission, but I just wanted to give the NSG a try. Even though I had friends with NSG's, I had never actually driven one. It was a complete leap of faith. So far it has been treating me well, but I'll admit that it's wholly useless with the stock 3.73 rearend, especially with stock tires. I'm still waiting for my 2.94's to get dropped off, so that will be the upcoming test.
Also, any NSG that bolts to a 3.7L engine will work for the swap. Mine actually came from a '07 Dodge Nitro. You really only need to be wary of any NSG variants that were used with the Wranglers, with either the 4.0, 3.8, or the pentastar.

Too bad you didn't take some pics, that would have made a super great write-up. And despite being a bit weak, especially for a gde tuned crd, I think you won't have any issues if you don't go ninja with the jeep... I also prefer manual Trans all day long vs an auto.
I did take SOME pitures, but not near enough to be useful. I do plan on doing a writeup, but I just need to find the time to sit down and collect my thoughts, I'm currently in college and flight school so time is of short supply.

Which torque converter is it? I may be interested in that.
It's just the stock converter, around 100k that I know of, the drivetrain was replaced at around 25k due to serious failure. I've put 25k on this thing myself and it has had zero issues, no slips or shudders. I'll let it go cheap, if you need a new one or a backup.
