I am getting ready to pull the trigger on a built trans and would like to know who is using DTT and their opinions of them. Which converter (super single or triple) did you go with and has anyone ever slipped the converter clutch while towing or in any other situation?

Lets hear it!

TIA

 

I run DTT, with no problems. Tim Barber builds and runs DTT, need I say anymore????

 

how are the VB in those trannies?i have heard good things, but never from the horses mouth.
i have a suncoast VB, that i bought from another member, who sold it to me knowingly that it was no good(they must have blown their tranny up with this one)and i had to replace parts in it, but it still does weird stuff, i can only compare to my stock VB with a transgo shift kit installed in it, which seem to do less stuff.

 

Which converter do you have? Do you tow?

 

I have a DTT, single disk with a race valve body, never slipped it, shifts fast and pulls hard every gear, about 40 passes on it now. Did not tow heavy with it yet.

 

I run a suncoast triple cause thats what I had in the truck when it needed to be rebuilt, so I have no clue on the DTT converter but your builder will give them a call.

 

We have a DTT in several trucks built by James in Midlothian Tx and so far they all seam to realt like them, we have one in a truck thats shoting close to 1000 hp or more and of course is fully billet and triple disk converter

 

Single disc converter in my truck, they do offer a triple now.

I have not had 1 problem, been happy since I drove out of their shop in Abbottsford(sp), BC. I spent the entire day in the shop with them, they took me through the entire build, step by step. I have never been treated so respectful by a business before or since.

I am not sure their outsourced dealers are as sharing, but I am sure their quality is equal or Bill K will not keep them.

DTT here as well - see signiture....works great, only thing i can complain abou is a 3-2-3 shuttle at real light throttle in traffic....and i havent taken the time to try and get it resolved. 6 Boosted launches at he track, daily driver, probably running 480+hp....it's good stuff

 

Im running a DTT in my truck as well, built by Terry at Moonlight Diesel. We went with the super single torque converter in my build. I also have the DTT Shift Enhancer which is supposed to resolve the shift shuttling issues. I'm extremely happy with this transmission, I haven't had a single issue and I've had it for about 40,000+ miles. It handles what I have in my sig, around 800hp. I don't do alot of boosted launches, but I regularly break traction...at least once a day!

 

Eli you know what to do and who to see!! Just go do it! Get the triple.

..

 

Can anyone explain the pros/cons of a triple vs a single torque converter? I'll have to ask Terry next time I talk to him, I'm just curious what other peoples' thoughts are for why it was suggested I go with the more expensive super single over the triple.

Jared,

The short answer to that is simply clutch surface area. Since diameter wise, you can only extend so much area in a single clutch, you simply physically run out of clutch surface area to work with, so you go to multiple clutches and that multiplies the area you have to work with. More surface area equals more potential to hold. Same thing with manual trannies and why dual disc clutches exist. Same reason internally builders convert the 5-4-4-4 clutches to 6-5-5-5... that lil extra area to help hold.

Now why he had you go to the single I cannot answer. Usually the triples cost more, not the single.

However, it has been mentioned more than once here how DTT put down triples for the longest time stating they not only were unnecessary but not as good as a good single. Now they offer a triple as well. So what gives? Just a question to ask yourself and others.

 

Most trucks are great with a single, if the trans internal issues are addressed.
A triple will rev a little slower due to the added weight.
They offer a tripple for those who plan to really abuse the converter.
I have seen several tripple discs break the input shaft.

 

When I unload Smarty, that shifting characteristic goes away as well......
