Ive done a combined weight of 30K Lbs from longview to skagit valley. They work fine for pulling trust me...

I don't doubt it, they are more than capable, but there is no way I could get my wife to do that in Seattle traffic with a manual. 

The 48re with a few mods is absolutely bullet proof.  I am lucky enough to have a good buddy that builds trans. so it wont cost much more than a case of beer in labor.  Just need this one to start acting up to give me a reason to do the build.

I would also add that Ive pulled 26k over the pass and back so many times I lost count. I used to put on 150k miles a year pulling my trailer.

I pull between 26k and 28k regularly, depending on what Im up to.  The truck does great.

The newer auto's are probably better. I had an older one. It was a dog except on flat level ground and the best thing i did was send it down the road.

For dragging or truck pulls an auto is likely the way to go... but for hauling freight a 6speed stick is the way to go.

We ran a few at work and never had an issue with the trans.  That's one thing GM got right.  It was everything else that turned me away from their 3/4 and 1 ton trucks.  We stopped using them in our fleet, they just couldn't hold up to everyday use.  They just fell apart around themselves. 
Had some engine (Duramax) issues to the point the dealer was just throwing parts at them.  I never felt good about them, we even had the service manager tell us to make sure we swapped the injectors out before the warranty was up.   :dunno: 
Never a transmission issue thou.

Allisons are the best but-rebuilds cost a lot more when they go.  The 48re is a common swap on newer Rams as it is cheaper and bulletproof for extreme use.  For 3500$ you can have a bulletproof 48re/converter.  Someday mine will be replaced with a Firepunk Trans.  I wanted a stick but it sold in the 2 hours it took me to drive to it. :bash:  Clutches are not cheap either.  I like the control of a manual.  I installed a Mystery switch/TQ lock-up. (CHEAP) Very handy, and does help with trans. temps but only at certain points.  To lockup 1-2 gears you need a valve body upgrade.  I dont.  But locking drive and OD is nice and helps coming down pass.  Also I use a race stlye quick flip switch as you may forget its on when stopping.  This can get violent and break shafts as cummins will refuse to die.

Firepunk Trans are the way to go, but shipping it here, and the core back makes it too expensive.   Add the triple disc TC and your pushing $5000 for a mild built trans you could do yourself.

So true.  I have a builder to build at my specs which happen to mirror Firepunks-almost. I think a turbo will do me in, if I ever get a new turbo.  I did find a new kit for twin turbos and its very cheap.  On3performance.  New untested product.  I hope to see reviews soon. :dunno: http://www.on3performance.com/shop/2003-07-dodge-cummins-compound-tt/

I was told 3rd inj. event is emissions egr stuff and to quiet engine.  The programs use it to their advantage usually rather than disabling it.  Its not responsible for egt temps as the tunes control it completely.  An aftermarket turbo will be around 12cm-14cm exhaust so engine isnt choked.  The stock 9cm isnt good for towing temps but spools quick and low for driving.  Older dodges turbo was 12cm as well.  Tater built turbos-google him- is great upgrade of stockers and cheap and all original 351 turbo. I will likely go with Tater or atsAurora 3000k.

Third event is ONLY for emissions. It is so far retarded (in timing) that the fuel arives too late to add any real power. Economy can drop by ~ 0.5 MPG. That change when towing from 10.5 to 10 MPG is a big hit.

The 1st (pre) event is to quiet the knock.

also, the pre and post event timing is referenced off of the main, so if you change the main timing, both the pre and post change.

Pictured is the pre, main, and post timing maps.

as usual (and we already kinda know this) 2200 RPM is the sweet spot for towing Keeps you from wasting fuel by getting the Post event activated, and it also allows for a slightly more advanced main event timing

Good info.  My truck likes 2300-2600rpm towing the hills.  Flat land much lower 18-2400rpm?  I run turbo boost up to 36-38psi max on edge.  Heck these are good in stock form but much better with few upgrades.  I understand that programmers can control the injection events and create power with these, pressure, duration and timing.    I really dont know the extra inj. event accounts for much mpg loss.  10mpg?  I ave. 12.5 to NE Wa. 400miles and 14mpg back home.  Towing good size load, and I have heavy foot.  No 50mph here.

Heading to the Desert 100 and back we got ~10 pullig the toy hauler, got the same heading to China Hat. This is a smal  trailer, but it is a barn door. Truck has 3.73 gears and is an auto.

My 2001 will get 10.8 doing the same stuff..and it will do it faster. But it has twins, cam, head porting, big injectors (mach 6+) yadda yadda yadda

Woodland did you check out my link on 3rd gen. twins?  What ya think?  Are you running a program on 3rd gen ?  Im curious how much mpg is effected.  I run edge on 3, 2 tow when hills around and stock up big hills when towing 27'TT.   Normal driving edge on 3, mpg varies 16-20ish depending on alot variables.

well, that kit is definately "pretty" Cant tell anything as they dont say diddly about the turbo. Also, it looks ilike it still uses the OEM turbo as the seccondary...so, well, you are still corked there.

Call Source Automotive to get a good set of twins  http://sourceautomotive.biz/

My 3G is still bone stock as the tranny is still bone stock also. If I ever do dive into it, the stock turbo is getting replaced by a Garrett Stage 2, the charge cooler is getting replaced by a BD unit ( I have one on my 2G) The Cam is getting replaced by a Helix II or a Hamilton. The the Kitty is going in the trash.

after all that, then I may just go with a Smarty Jr....oh and a tranny... all that should get it to ~20-22 empty and 12 loaded but I cant justify the cost as of yet.

Pricey place.  If I do twins it will be a stocker/s472 type kit.  Im researching info on that on3 turbo trying to get info.  Think its about equal to s475?  Great company with the gas turbo community is all I found out so far as this 1st diesel product.  Firepunk tested with them and said real good things about product.  Do you know this company? http://www.agpturbo.com/agp-bw-cummins-5-9-bolt-on-turbo-upgrade/     http://www.theturbopro.com/SearchResults.asp?Cat=1819  Reasonable prices. ATS Aurora 3k, 62-65-12or14 from Tater is what Im thinking for a good single without crazy mods.  Or twins and arp studs? Want good tow rig.
