Smartshift

I'm driving a company '07 century now, I didn't think I would like the auto but got use to it. You just have to get use to starting it and reverse - jerks you if you hit it the pedal too hard and won't move if you just take your foot off the brake like a regular car.

Its nice on regular road but sucks in traffic - have to switch to manual mode and just shift it up and down yourself - at that point its fine. Otherwise it shifts and jerks you way too much in traffic.

Going up hills, have to downshift it (still in auto mode) because it will lose too much speed if you wait for it to shift.

A lot of guys say its bad in winter (snow/ice) - never had a problem with it, used the jake with it without any issues and if anything you can always switch to neutral with just a push up.

Jake brake - stopping is much quicker with the auto than manual trans - it has a Low mode, if you have the jake on and throw it in low, it downshifts much quicker and stops quicker. I rarely have to use the brake, even with 70-80K loads, just flip the jake on high, switch the trans to low and you're good to go - smaller hills you'll have to switch the trans between regular Drive and Low because it'll slow you down that much and quick.

I've drove it for about 65k miles now and no problems - that's as much as I know as far as any breakdowns. Truck has 800k miles on it, so just under 1,300,000 km.

Hopefully that helps, and not too confusing.

 

Pretty sure the 13od will be much better, defiantly better on fuel mileage. Not sure about the cat motor either, not a fan of it...
