'15 JEEP GRAND CHEROKEE AND TRAILER COMPATIBLE?

The new GC paddle shifter with the gas engine should do a good job of engine braking. But yeah, the diesel is a different animal.

As I understand it, the 8 speed is set up so well, there is no need to lock out overdrive. I guess there isn't an issue with unlocked torque converters; instead of trying to get a little extra power by letting the converter slip (the way my Highlander does and so many older vehicles do), the new GC simply shifts to the next lower gear!
