how good are the 6 speed autos. do they still have weak input shafts and tc. or is the 6 speed manual still the best way to go on these trucks.

they aren't great, but mine is still holding up. my mods are in my sig. and i have 24k miles on my truck. i dont drive really hard but so far nothing has broken. the input shaft aint real beefy, but i havent noticed the tc slipping or unlocking yet.

so it looks like the 6 speed manual still is the best way to good

the clutch is a piece of crap though on the manauls

seems like you can buy and auto a lot cheaper used and the manuals are priced higher way. when they come new manuals are cheaper.

not to sure on the autos but the manuals the clutches are junk mine only has 17k on it and the clutch is about had it and im thinking its about time for an upgrade

diesel pap or cbrahs there can set you up

so you are telling me i can't go wrong with both they are both good on the 6.7l. what about the 5.9l 48re or manual. if i buy 6.7 i'll delete dpf and egr and put a chip in for the fuel mileage and cai. this truck will have to last me long time.

I have plenty of mods on my 6.7 and the auto is holding up. However, I don't do boosted launches or go WOT all the time - I just treat it nice.

That's a huge improvement over the 48RE's - that would slip with stock power.

I didn't get a manual for a couple reasons. First, I don't want to shift all the time. Second, they are considerably slower than an equally modded auto. However, they are cheaper to upgrade and handle more power with an upgraded cluth - than we can we basic upgrades to our autos.

But, if you compare a built auto to a built manual, the auto will win hands down everytime.
