What I ment by "with the 6 speed the rear gears arent a real issue"... . is that getting around town and starting off the line with the load... the 6 speed offers such a nice selection of gearing. I know top end there is a difference and I know the GCVW is different... but drive-ability with a load, I don't notice it with the 6 speed.
Also if you plan on larger tires, the 4. 10s are a must... . which is one thing I regret with my 3. 56's...
My buddy with his ETH/DEE (4. 10) towing his 10Klb 5thwheel, Vs my 6Klb TT with Auto (3. 56) , get almost the same fuel economy when towing up state... . 10. 5 - 11 mpg
Learn something every day, when my buddy spec his truck to be built and back when I was looking for mine I couldnt find a scratch of literature that offered the LS with the 3. 56's.
I agree with the 5spd 5th gear nut issue. . Still hear about it.
But thats it.
The one large problem they had with the 6 spds was in the beginning and the shipment of trannys stopped till the problem was fixed. After that, I havent read about another complaint.
And that had to do with the smoothness of shifting. My buddies 6spd was after that whole rig-a-ma-roll. . it's soo much more smoother than I expected. Tigh gating and smooth between all, easy in and easy out.
While I'll be spending money with DTT for my Auto... except if you really want an auto, I don't see a reason to buy the truck with an auto, spend a bunch of extra money to bomb it to the level of an ETH/DEE and all the money to modify the transmission, killing your warranty, when you can just buy it off the lot that way... .
I myself have ETH/DEE envy. . I wish I had that option when I bought mine.....
Oh well.....
What a life... . we have such great choices... what a thing to be worried about... we have it great. I visit some hell hole countries, it's a great reminder.
