Kinda surprising that they didn't already have it, since I'm told the Allison 1000 has everything for 6 speed except a servo or two. And does that mean the GM trucks are basically getting the 2000? Which, IIRC, is just the 1000 with 6 speeds enabled and higher pressures. Been a long time since I did the reading on the trans, so that may not be completely accurate...
Not sure if its the 2000 or not. I "thought" the 2000 did not have a parking pawl, but I cant remember...(getting too old) John
Hmmm, seems like I remember that too. Or was that the 2200? <shaking head> I'm getting too old too...
Looks like the alison wont be the only improvement for 2006. CLICK HERE Im sure some of you have already heard this, but others may have not.
I could be wrong, but I thought the 2006 truck in question was a limited addition high performance model and not the normal production diesel.
1) I don't really see the need for a 6 spd auto. It's another gear that is shifted in and out of all the time and jacks the rebuild price up even more with yet another gear to rebuild. When combined with the torque converter lock up I would think a 5spd is plenty, especially when the Dmax is supposed to have this big fat powerband anyway. Heck, Im happy with m 4spd auto behind my cummins that has a narrow power band. I wouldn't mind having one more gear in my tranny but not a two more gears. 2)I personally don't see the need for more power than what is available currently. With current '05's being over 300HP and 600 ft lbs....thats a LOT of power regardless of how much someone is into the hop-up craze. Heck my truck is only 235/460 but it honestly is plenty for most resonable loads. The manufacturers need to be thinking about what weight class these trucks are, LIGHT DUTY. 3) Eventually the manufacturers are going to kill the BOMBing craze from the aftermarket suppliers. Back in the early 90's when the cummins had a rating of 175/400 it left a HUGE margin for bombing but with basically the same block making say 350/700 now...that leaves a lot LESS room for BOMBing fun before things start to get unreliable. I like seeing the guys using non stock turbo's, injectors, etc. to get numbers WAY higher than stock but with this idea of 700ft lbs+ we would definantly be running out of room for cool mods.
Never mind I went and looked it up...I guess I was smoking crack and halusinated the extra gear hahahahahaharotfl
6 Gears can be better even for the DMax for a variety of reasons, as long as they don't just decrease the gear spacing. For instance, first lower and then stacking up to the roughly the same OD with a higher axle gear gets the same performance as the 5 speed but a lower cruise rpm. As currently produced, the DMax cruise rpm at 75-80 is about 300 rpm above ideal for fuel mileage. Same could be produced with more OD, but that would have more component strain issues. And it's really not much more complicated. Because of the planetary gear nature, it already has all the hardware in place for 6 gears anyway. All it needs is servos and clutch packs, which are also mostly all there since it's supposedly just missing servos that looses the 2000s 6 speed nature. And on the more power not being needed, I agree and disagree, hinging on "needed". Clearly the trucks can get their work done without the power, but the extra power makes EVERYTHING so much nicer. For instance, with the extra power I can keep the truck in OD on 4* inclines with 15k gross and still keep reasonable (though high) EGT. Without it, it shifts down out of OD and roars all the way up and over pretty much on the redline. Fuel mileage sucks like that and I gotta think it's harder on the engine, not to mention getting on my nerves. It also greatly improves on "drivability". My truck moves in traffic as easily as my wife's super charged GP, merging into fast traffic, pulling onto a crowded road without needing a 100 yard opening, or passing a slow-poke on the 2 lane. It worked well stock, it works MUCH better now, and I'm not talking about the odd embarrassed look on a ricer's face... And just to make this post completely diametrically opposed... I don't think you're right about the Bombing being shut down by manufacturers, at least not across the board. In order for them to produce stock trucks with ever higher ratings, they have made changes to enhance durability so that they can maintain their comfort level and profit margins in the face of potential warranty failures. I agree that the ultimate amount of "Bombability" is pretty much stationary, primarily due to ultimate strength of the block and head. The entry to intermediate "bomber" like myself will (I think) actually find it easier and more dependable due to improvements in fuel control, turbo design, and so forth that open up easy opportunities for improvement that the manufacturer is not going to tap because it is calculated to only increase sales by n% while increasing warranty work by more than the addition n% sales would offset. Just my thoughts...
Seems like every new automatic innovation is to only try to make a truck with an automatic perform like one with a manual. Y'all can have your uber-expensive and complicated automatic transmissions. The 6 speed manuals more than do it for me.
Actually, I think it's just the opposite. They are trying to eliminate the drawbacks (other than complexity and cost) while keeping/getting more improvements over the manual. I liken your statement to the "GM 4x4 trucks suck because they are IFS" type of complaints. In these cases, one is not inherently "better" than the other across the board, but people all too often take their choices/needs/misconceptions to be the "ultimate truth and one true way", and anything else "sucks". But in reality, each has its benefits, and some are HUGE for certain categories of users. That said, I also like the "in-control" feel of a stick and might even have one just for that reason, even though an auto makes infinitely more sense for the way I want to use the truck, and the fact that I would have to upgrade the clutch/plate/flywheel just to get the power handling capability my Allison has stock. However, I have a plastic left knee and other artifacts of a miss-spent youth which pretty much eliminate that as a possibility. I guess I'm lucky to live in a time when the autos have reached the point where they are superior to sticks in many important ways...
YOu prefer manuals, we all know that. The majority differ, obviously because the manufacturers spend probably five times the amount of research on improving their autos than manual options. I definantly agree with BadDog and don't appreciate a one sided attitude. I used to want a manual behind a Dodge CTD too, but after my dad bought his 454/NV4500 '98 C30 I was convinced otherwise. One trip through downtown California traffic and about had enough with the stick. With todays autos, and the adition of another gear to every manufacturers auto every few years, the manual isn't so superior with transferring diesel power to the drivelines anymore. From my experience, they are a match made in heaven these days. Regardless, the manual option will probably always be there for the guys that exclusivly have to tow.
On bombing at least in California I predict it will come to a end in the next 5 years when the gov. starts smog checking diesel pickups. At least the blowing black smoke all over. In big rigs why would I want a bombed 3406B Cat when I can get more from a stock C15 Cat.
You may be right but I would think they could only inforce that on vehicles that would require a smog check after a certain production year. All of us that have diesels made before a smog check should be exempt, only trucks manufactured after the law. I THINK that is how it would be but not positive at all. Besides, let them. Unplug are little boxes, bolt on the stock turbo & injectors, and what else could they wine about?
Any of the diesel PU's that we're talking about came from the factory with federal smog equipment stock. Also on big rigs in Kali the CARB boys in their white vans set up along side the CHP/DOT inspectors sometimes doing "snap idel" test on rigs of any year. Hell I remember when Kali made us install PCV valves on our cars that came with road draft tubes stock.
Any smog equipment on most Diesels is minimal. Bobby, When your 47RE fails, I doubt you'll be doing anything but crying about what a POS it was. It's just a matter of time...Dodge Autos suck the big one, one of the major downfalls of their trucks IMO. Russ, I know how you feel, I have a bad right knee. Luckily it doesn't stop me from pushing the stupid pedal, that one's much easier than the clutch.
Tim, everything can fail at some point, It would be funny if for some reason "your" new cummins had problems at 3,000 miles just because it was "yours" and supposedly was not supposed to suck. I'm not a big fan of 700r4's, but when I took mine out (Blazer) it had almost 200,000 hard miles on it while others had problems at 2,000 miles. I can understand manual being stronger than auto, I just don't understand the "What I have is better that what you have" view, that you seem to have on everything.
Don't be an arogant butt head. When my tranny fails I'll place a nice little call to the guys over at ATS diesel....infact...I can't wait to call them. Then, I'll make another cute little call to my warranty company to arrange a brand new 47RE to be installed at my local dealer, on them of course. Then I will take it down to my TH700R4 buddy and have him install the VB and TC. I'm not like some people that automaticly think just because a part lets go it must be a POS, things just wear out, it's the law of nature in the auto world. You won't be so cocky when you melt the clutch on that 6 spd and are forking over 1,300 bucks for a new hi performance clutch. I've already looked into that stuff. For a not even double that I can have a built auto that will live happily ever after. This is my TH700R4 all over again. You and MJ said it wouldn't last a year....that was almost three years ago. imp:
