Well let me say this:
1. The trans problem can be fixed for under 80$. It just needs new servos and a bigger cooler.
2. The awd system is fine with higher hp ones. I know of abunch close the 500awd range and they are holding just fine.
3. Gas mileage is about 17-18 cruising on the freeway.
4. Most important, IPS now has the hp tuner credits to tune them. Also they will be making CIA for them as well for less then ones on the market sell for.
SS vs SRT8 jeep:
The jeep from the factory is faster cause they have 30 more wheel. But with a tune and intake you can be beating them all day. Or if you want, do what I am doin to mine and beat 98% of Cr.
