In "your opinion" who has the best auto tranny and describe "best" for you. This one should be good. :popcorn:

Not Dodge
































Tim Says so:stir: :popcorn:

The Allison is by far the BEST slush box out there..why? Because I own one and would never buy someting that is second:stir: :popcorn:

GM Allison.

Nothing more to see here guys, just move along.

Steve, might as well close the thread, discussion is done...

:stir:

I don't really think that there's going to be much discussion on this one... :pimp:

You guys are full of it. The 47RE is hands down bullet proof and extremely reliable, even behind a seriously modded Cummins. Nuff said. waytogo






















































After recieving full BOMBing upgrades from ATS, Suncoast, or DTT or course. rotfl

In stock form the Allison, in full out Bombed, the 47RE.

Only if you compare the fully bombed RE to a stock Allison.

Bomb them both, and the Allison still wins with less money invested. Look at the cost of a SC Lvl 5 for full boat ATS for either, and the Allison is cheaper (last I checked). Sorry, but dollar for dollar (as long as you ignore the initial option purchase price of $1k :eek: ) the Allison will always win. If you count the initial cost premium, it's probably a wash I would guess? But the Allison is dimensionally larger on all internal pieces (that I am aware of) so it theoretically wins anyway. :D

Who cares? :stir: :stir: :stir: :popcorn:

I was comparing a BOMBed 47RE vs. a BOMBed Allison and would say the 47RE is most proven simply because it has been modified the longest and is standing the most power. As for cost, thats a non issue for me since it doesn't matter if you have a GM or Dodge, you aren't going to swap in an allison because it costs less to bomb, you get what you get with each brand.

Ok, I guess I can give on those grounds, but I still say the bombed Alli is stronger, though your right, it has not been out there as long nore has it seen the ultimate torque that some of the Dodge guys have run through theirs, so no solid proof.

But I didn't say anything about swapping, only that the Alli can handle more power dollar for dollar. Just a statement of fact (at least as far as I know it). The relevance is up to the reader...

The relevance is up to the reader...Yes and I agree but the only time that matters is when a person is trying to decided which brand to go with, with the cost of BOMBing in mind.

If you already have a Dodge, what it costs to build an Allison vs. your 47RE doesn't matter, because you have a Dodge :popcorn: .

I would say it's at least as relevant to a thread on "best auto" as comparing relative strengths/limits/costs of Cummins vs. DMax vs. PS, or IFS vs. SFA, or any other "which is best discussion". It's simply another data point that people can mentally tally to draw their own conclusions about "best", but that doesn't mean they want or need to go out and get one...

I'd say Allison has been building auto trans that hold up to high torque behind diesel engines longer than Dodge or Ford.........:stir::stir::popcorn::pimp:

Nobody answered my question. rotfl

Nobody answered my question.
Ok, since you insist. Here is your answer.

Who cares? How about those of us who don't *need* a truck with a large phalic symbol to compensate for areas in which we are lacking, nor do we *want* to ride around all day with our hand wrapped around the end of such a symbol...

:poke: ;)
:stir:

Not in a GM light Duty pickup, infact, I think the 1000 series Allison was built specifically for GM and was not a previous design.

Which other manufacture has as much experience building auto trans to use behind diesel engines as Allison? Which other manufacture has as much experience building auto trans to withstand high torque output engines than Allison? If the 1000 series trans was built for the GM PU's wouldn't it give them a leg up on the compition?

I didn't say Allison doesn't know what they are doing :rolleyes: ....I said the 1000 was a new design itself IIRC.

Who cares? :stir: :stir: :stir: :popcorn: I'll bite. THose of us that don't want to deal with turbo lag care. Those of us that have better things to do than push an extra pedal and stick from stop light to stop light in California rush hour traffic care.
For those of us that actually daily drive our trucks and don't tow with it 100% of the time care. For those of us that want a diesel powered truck that can get out of it's own way care. For those of us that prefer a tranny that is smart enough to manage shifting itself and letting us do something that is more important, care. :pimp: :popcorn:

I like your answer better, but mine's funnier. :pimp:

Better things to do than, uh, drive?:doah:

Speak for yourself... As for the "getting out of it's own way" part, a manual truck will get out of it's own way no problem when it counts, passing or merging into traffic when shifting isn't required. There's no delay for the TC to lock up and it won't hunt for gears or downshift when it doesn't really need to. I'm not into drag racing 8000 lb diesel pickups, and as far as I'm concerned that's the only thing the auto trans does better.

So you want a trans that enables you to be lazy and concentrate on things other than driving? When you're driving, what's more important than driving? Does it really take that much thought for you to figure out what gear you should be in? That's a piss poor reason in my book. Aside from the inconvenience of having to shift your own gears and accelerating from a stop faster, what benefit does an auto give you?

This is the wrong thread to debate this issue, but I had to reply. I don't know why any of you even bothered answering Tim's smart ass rhetorical question, other than that he baited you into it.

Hehe, relax Shaggy. I replied to Tim just for fun.

And not wanting to shift in stop-n-go city driving is not anywhere near saying "I've got more important things to do than drive ". When I'm driving, there is NOTHING else I'm doing except maybe talking to my passengers. I refuse to even talk on the cell phone (and firmly support the death penalty for those who do without a hands free, and I *am* serious) and I will mess with the stereo or something ONLY if I'm completely in the clear. But at the same time, on the surface streets around town, or freeways in rush-hour or construction or wrecks with all the brain dead drivers slowing to a stop for no reason, I absolutely do prefer to use nothing but the fuel and brake. Shifting is not hard, and when I had a decent left knee, I always preferred a manual simply because of the "feel" (for lack of a better word). Not because of some irrational auto-phobia, or misconceptions about manuals being the only "real transmission", but rather it was because I liked the pros vs. the cons for me and liked the "feel". But even then, dealing with traffic would get really old as I shift up, and down, and up, and down, and up, and down just to cover a city block, especially if it really was *stop* and go AND up hill. All the slipping the clutch to "creep" smoothly and move up 2 car links or what have you. It's just frustrating when all I do in the auto is let of the brake for a few seconds, and reapply.

I'll let the "get out of it's way" thing pass. Each transmission has pros and cons in that respect, and they don't all revolve around towing or drag racing, but that's a discussion I don't have the patience for right now.

No, I have nothing better to do than driving. Shifting from one gear to the next is not driving. :) Holding on to the wheel and watching the road/road sings/other vehicles, keeping yourself from getting into a wreck and not breaking the road laws is driving. ;)
I'm not lazy at all, eveyone of my work vehicles have a manual transmission. Our C30 has a pesky 4500 and our F600 Ford service truck is a manual rig. I just get tired of shifting and dealing with the drawbacks of a manual. My personal favorite is being at a stop waiting for traffic in the F600 and the road is slopped and I keep wanting to roll backwards while some pinhead in her Honda comes up and stops 2" from my bumper. :mad: .

I've driven a couple manual diesels. They are considerably slower than auto versions. Having to deal with turbo lag everytime you shift slows it way down. I'm not saying that it you can't move with traffic but I can easily accelerate quickly for a reason without a liberal amount of "pedal." The tranny and converter are almost always in the right gear when I step on it. I could also see how fuel mileage could suffer with a manual in bad traffic, the auto lets the engine stay in it's powerband and keeps the turbo making boost. I could see how a more liberal use of the throttle could be needed to make the best out of acceleration in each gear, and doing so while not in the powerband and adaquete boost for a short duration, especially for the narrow powered cummins, could make a difference in fuel economy

There are a lot more benifets than just drag racing.

A manual trans gets better mileage anywhere, that's just a fact. The auto trans keeps the engine in it's powerband by allowing slippage, creating heat and wasting energy. I'm not sure about the Dodges, but the Fords with manuals get 2-4 MPG better in any situation, not just on the highway.

Now that I'll give you, when *properly driven*. But frankly, most don't get the mileage increase because they can't/won't/don't care to watch the tach and know where it needs to be. It only works as you suggest when done properly. Driven the way most people drive a manual, you see very little if any improvements in town or mixed mode. Intuitively it seems to me that it might still make a difference on the road, but then again, the Allison and most any modern auto will be "locked" on the road, so I'm not sure how the manual could be better assuming final drive is the same.

Also, no personal investigation, but apparently the Allison does manage to close the gap to a very narrow margin in city and mixed-mode as well, even when the manual is driven optimally. Supposedly this was accomplished with additionally converter lockup and ECM/TCM communication keeping things at the ideal levels.

The Allison is breaking the rules of auto trannies, the thing is probably the smartest tranny ever made, IMHO. It's the only auto that I would have gotten in a new truck.

I know that it's apples to oranges, but my DD is an '03 Jetta TDI with an auto trans. I've gotten 41.16 MPG lifetime average on it, and that's 62,000 miles in 14 months so it's pretty accurate. A 5 speed version of the exact same car would be getting more like 52MPG on the drive that I make every day. I know it's a much smaller vehicle, but being that my drive is 95% highway and I still get 20% lower mileage than a manual car, it tells me that there are definate inefficiencies inherant to an auto trans, even when the converter is locked on the freeway.

Id have to agree.. for an auto, the allison wins.. If I could get a Ford body with an allison auto and a CTD, Id be SET!

Scott Now THATS what I'm talkin about waytogo .

That would be my choise also. Ford body cdc isb engine allason trans.
FO=ford body
CU=engine cdc isb common rail
AL= allason trans
