Not all of them are crap, as I can attest to. Having 3 trannys fail at about the same mileage from 3 different years, just doesn't compute. There must have been something else going on here. Since you reported a good maintenance schedule, I would question who did the maintenance.
Wrangler getting a minivan engine?

As an offroad enthusiast, I can say that the 3.8L will be totally adequate in offroad situations, that's what Lo range on the transfer case is for. Hopefully they will keep the 4:1 ratio from the Rubicon, then it won't matter offroad.
On road performance is most likely what they had in mind with the switch. The old 4.0L straight six is/was a bulletproof engine allround. It will be nice though, to hear a different sound on the trails when guys start taking these new Wranglers offroad. As it is now, you can tell when Wranglers are coming down the trail before you can see them, the 4.0L has a very distinctive sound on the trails. Not a bad sound, just distinctive.
The 3.8L V6 should be lighter, a good thing for the trails. And easier to upgrade for too.

The T-case is still the NV241 and yes, it is still 4.1. However, you still need torque down at the low end when you're going 1 or 2 MPH. At that speed, even with a 66:1 crawl ratio, the engine is only spinning around 1400RPM. Trust me, my YJ Wrangler has a low range around 100:1 and see's 95% trail use. Jeeps need low end torque.
The V6 IMO, was just an easy way out to comply with the latest and greatest emissions requirements. Yeah, it makes the Jeep move, but it's not ideal for the trail.
Will a real Jeep engine please stand up?
HARDLY A HYUNDAI ENGINE AT ALL
A little more up to date info. To say the World Engine, used by the Chrysler Group in 1.8, 2.0, 2.4 and 2.4 Turbo in SRT4 Caliber is totally designed by Hyundai as implied above is mis-imformation.
From Allpar 2/13/06 on GEMA World Engine
"Reportedly, the basic block was designed by Hyundai, but Chrysler and Mitsubishi then made a large number of modifications to make it more efficient and adapt it to their uses and technologies. Most of the packaging/dressing components, such as intake manifolds and valve timing equipment, appear to have been developed by each partner independently and will be used independently as well. For example, the variable valve timing was developed by Mercedes and is used on the V6 in the E-Class. J.L. French in Wisconsin makes the blocks for American engines, with Nemak providing head castings from Mexico.
While some have said that Chrylser paid $57 million in royalties to Hyundai for design work, an informed source noted that the funding for GEMA was put togther by all the partners, and that $57 million was just DCX's share of the GEMA funding. GEMA itself is a separate company from DCX, MMC, and Hyundai, and it pays royalties to external and internal partners and patent holders.
According to the Dodge Caliber press release:
Chrysler Group brought its engineering expertise to the World Engine program in the areas of cylinder port and intake manifold design using advanced Computational Fluid Dynamics tools. Chrysler Group engineers led the development work on dual Variable Valve Timing (VVT), as well as an integrated 2:1 oil pump/balance shaft assembly. Chrysler Group also refined the engines for exceptional smoothness and sound quality.

"
The engine has a high-pressure, die-cast aluminum block and will be built in a new joint-venture plant in Dundee, Michigan; blocks for the Dundee engines are made by J.L. French of Wisconsin. The engines built in Dundee will most likely be used entirely in Chrysler vehicles at first, though we'd expect Mitsubishi to use the same engines for their American-made Eclipse and Galant. We have no word on the fate of the plant that makes the current 2.0, 2.4, and 1.8."
The Chrysler Group will take the lead in operating the two Global Engine Manufacturing Alliance facilities in Dundee, Mich. GEMA is investing more than $700 million in the 1 million square-foot plant, which will create approximately 550 jobs in Southeast Michigan. Each of the two Dundee plants will have capacity of 420,000 units per year."
Note according to a Chrysler Engineer involved with the program, when asked about this on the Allpar Forum, told us The GEMA was/is formed for liscensing purposes and to spread the cost of the tooling for all the plants involved.
CG Engineers and Mitsu took the basic Hyundai design for the block and that was about it. The piston size and bore spacing and displacements are the same. However the block for CG use was re-engineered for CG needs including turbo charging. The intake, valve train is different between all three. CG utilized Merceded VVT technolgy and engineered it for their own needs.
So basically the engine going into a CG vehichle was designed for the most part by CG engineers and is different relative to Hyudai& Mitsu. The blocks, manifolds and valve train, software will all be different. Also the Dundee plant is really a spin off in name so they could get tax incentive from the state, but staffed by CG people.

I saw a photo of another new Jeep, the Patriot, which at least looks less ladylike than the Liberty or the Compass.
VNT,
