Still sittin on the fence:confused: I need to know what kind of cash im going to have to part with. This is going to have to be an undetectable purchase, as MOMMA BEAR would not be happy if she found out that i purchased a tranny and not a RING:help2: Ive got several places to grab cash from, but i dont need her to find out:bawl: When this is released i think that a STAGE 2 is the way to go:clap: BTW Juice if i get caught its all your fault:D RIGHT.

How does one make an undetectable purchase?... well, seeing as how you haven't bought her that ring yet (LOL) you could buy both at the same time.... that would definately 'hide' it.

I doubt anyone will buy into anything that doesn't come with product information. If DTT wants to get this product off the ground they need to let a little info. out past their inner circle of employees and friends and share with the public. Simply saying you have a superior product with reasonable pricing is not going to cut it. You can only maintain secrecy for so long before potential customers will just move on to other available products. (my position at this time) This poll is reflecting the lack of public information if anything.

From the talks I have had with them, I think the SII kit wll be in the the 1800-2 range. Then you put clutches/converter/gaskets/filters/fluid/custom machine work for setting clearance on assembly and your easily into the high 4k range to almost 5k.

The Alto Clutches I have tested were NFG. The Stock Clutches seem to be the way to go.

Well, I'm officially "on the fence", but would rather "wait to see what others think", since it is a brand new product with an entirely different design. (BTW, I think innovation is COOL!) :cool:

It would be nice to see a complete parts breakdown for both Stages, with all-inclusive lists of parts and prices to completely upgrade the transmission. Saying "maybe 4K to 5K for a Stage 2" is way too vague.
So, what converter would you recommend with a Stage 1, Stefan? Juice? :ro)

Not to speak for the DTT bunch, but I do like the way of thinking they have approached this. Its no secret that the OEM clutches are excellent and since most builders have access to these, they dont include them normally as we as builders would pay the same they do for the most part. That also gives the builder the option of using them or stacking in some of the aftermarket options that are coming to the table. As for a converter, you cant go wrong with one from the big 3. Hey Bacon, put up some money and lets build a unit... you could be the MI test whore!

I have their single disc convertor and am well pleased with it. My experience has ONLY been with a single disk.
I probably have 100 passes on the 1/4 with it (some on track some off;) )
and 35K Miles hard towing on it; and about 20 dyno pulls.
It goes about it's business quite well. One thing i can say is that the stall speed is very low, and there is not much RPM drop between shifts.
Having said that, I have not tried the triple disk convertors and cannot make a fair comparison about that. The convertor i have is not for sale at this time. But it is the same one i had in since my transgo days and has not slipped, moaned, shuddered, ballooned, or any other shenanigans to date.
FWIW, the pricing difference between Stage1 and Stage2 is relatively cheap. If i was going to DTT, IMHO i would opt for Stage 2 and be done with it.

Looking at the website infers a couple of things. The first is that they don't want to alienate buyers by telling them they 'have to' use a certain convertor and the second is that clutch preference is left up to the customer/builder.
Interesting.
We have tried the Altos, and found them to be less durable than OEM.
My Stage2 has all OEM clutches built into it.

Anyhow, Judging by the orders placed, there have been more than a few people 'just looking' at the DTT transmission.
Me, I have paid the $$$$ both in parts cost, vacation time spent at DTT, and time without the vehicle for testing testing testing.

Glad to see the fruits of their labours garnering such notice. Even happier to be a small part in it's development.

As for the Twins, I suppose they picked me for development because of my commitment to performance and possibly as thanks for my small time contribution in the R&D process. Other than that, I do not know. There were a lot of DMX enthusiasts a whole lot closer to DTT than me. I suppose I am just lucky to have their trust.

Thanks Juice. So it's kind of a "start with their custom parts, then buffet-style for the rest" type of thing.

I kinda like that idea, it gives a lot of options to the customer/builder!

and in the end, what condition were the guts in? You never did tell me.

Tom :pig:
C1 and C2 had factory clutches (billet DTT pistons C1 and 2 as per stage1), DTT had increased pressures over factory.
Results: C1 and C2 clutches and Steels looked in good condition .

C3 and C4 we used for testing the ALTO clutches, C3 and C4 pistons were factory items.
Results: FUUUBAR! C3 was cooked, Checked and was starting to delaminate
C4 was in the same condition. All steels were thrown in file the garbage. I guess yellow is not a fashionable colour for Kolene?

C5 was in good condition.

Bill did say that towing was one of the better tests for a modded allison. I never run below 400 RWHP when towing (usually 19-21GCVW). As a result there was slight wear on the critical C2 clutches, but they were and are being reused! Steels were in good shape as well.

I guess towing in the mountains can be as brutal or more so than just 1/4 mile runs in an unloaded truck.

Anyhow, I will not try to 'sell' anyone this trans. Do I like it? You bet! Is it better than the other choices? Some people are already switching. Some are switching to try it, some are switching because of lack of success elsewhere.
How does it shift? Like a modded TH400 but not as harsh. There is no 'slippy' feeling between gears. You are either in the next gear or you are not. I don't feel the need to endorse anyone's product, in fact i would be terrible at it. When the others that have switched are all installed with their new transmissions they will be the ones to make the A B C comparisons valid. I can't do that because i have never had a Stage5 Suncoast or an ATS Trans.

Hope this does not confuse anyone

Juice, your only doing what everybody else does, nothing wrong with promoting what you use if you like it.

I agree, go with the S II and be done if doing it, you need to address the C3 and 4's in a proper build.

Tomac expressed interest in 'testing' a unit too.. might need to make a test mule out of this core I have...

DTT's approach seems very interesting. Does DTT plan to offer a complete trans package with a warranty? If so what is an approximate price?

So far I've seen the Phase I ($675) consisting of DTT's new "trick" C1 & C2 pistons and C1 clutch housing/components. Phase II ($1700) includes Phase I items along with a modified case and C3/C4 pistons. These are in kit form and would require professional installation, additional parts (i.e., clutches, gaskets, filters, etc.), a converter up to the task, not to mention freight costs.

I've estimated the complete cost of a Phase II to be at least 5K, but my major concern is since it's not assembled (at least for the present time) by DTT, who'd warranty the trans?

I believe Suncoast Stage 5 has a two year warranty and ATS carries a similar warranty. When I spend 4-5K on a super trans I expect a warranty of some kind.

Well, try the DTT trans and put a SunCoast Tripple-Lock in it if you want a good converter.:D



.......... Now that's living on the EDGE! :eek:


Not that DTT doesn't have something that's good...... it's just that it has yet to be proven on the open market.:confused: If you are really worried about failure.....then you will not be top dog. If you want a good transmission right now,turn-key style, buy a SunCoast or an ATS with a warrenty and be done with it. All that you could loose in two years is "maybe" some down time. These 'builders' are always looking for ways to improve the transmission. If your builder were to find out that there 'could be' a problem..... they will ask you to bring the truck in {I say that because I know Joe would} for an update. It is cheaper form them to do that than to have bad press and have a *free* rebuild/install on their hands. ;)


OR.......... just wait another 6 months for the DTT trans to pan out.

Ok, back on topic.....

I'm putting together my lists of parts.....
Do you still have to use the Transgo kit?

What clutches would you guys recommend for the Stage 2 kit? I don't know who manufactures the stockers. I've been searching, and found Raybestos X-32 clutches along with Alto Red Eagles. I know a lot of you are starting to question the Altos.....


Lastly, what with all the battling back and forth on the trans forums, if you use another makers converter, will your trans blow up due to spite? :joke:

Tom :cool:

Mike L.
02-17-2005, 11:03 PM
BorgWarner makes the oem clutches and the lining for the converter clutch. Raybestos make a replacement clutch which is suppose to be better than oem. They also make a one sided C2 clutch called a Z-Pak. There are 2 testers on this board testing them and I am one of them. No coment yet. As far as converters go, you can use any converter with any combination without worry. I am using Trippins ATS converter at present for testing with Raybestos clutches. That will change very soon as I will be testing 3 other converters and different clutches. I will make a comparo when I am done. ( same truck, same program, same driver) Drag strip times will not be relavent and won't be considered since I feel it wont matter.Almost all of our driving is done on the street, towing and such and that is my primary concern. For you guys that are pushing the power envelope( 600 hp and above), you might need custom tweeking on the converter. Anything below that number wont matter.

03-11-2005, 09:21 AM
I think that Bill at DTT is right with no more piston apply area to hold the addtional clutchs your going to loose clamp load. Plus I don't feel it's the lock-up that's the problem. I feel that under large boost there is to much slip for lock-up apply to deal with. That's why T/H work so will for drag, lock-up comes on after the 1-2 shift not giving the torque time to run away. So for the price for now I'm going to use a billet cover, one clutch unit from here in canada.
