and I won't try to claim that my trans/truck/converter are the fastest to spool , but if it is a little slow/tight, it is a great trade-off for the drivability that it has!!!!



I did not buy it for street racing/drag racing. It pulls my trailer like it isn't there and is fun to drive with out a trailer. No sloppy-loose starts. It has nice shifts that are firm.



I disagree with the statement that if it was looser in fluid coupling the clutch won't hold. Maybe with other designs but not with a DTT.

With or without a trailer, I can drive it all day with out reving it past 2000 rpm. of course after 75 mph It goes past that.
Sir when the speed limit drops to 65 what gear do you use then when towing? What about 60. I don't have a thing to say bad about DDT. I don't wont a converter that is slow to spool though. jimk
 
Wiith my set-up I can tow at 60. It is not recommended. I pulled a 8,000 lb trailer thru the Chatanoga area I -24. ran 60 in OD and locked up. No issues. love it With my PDRhx 40, it will smoke till 5 lbs boost. I don't intend to spin tires. if needed tho, just hold the brake and get some boost, they will spin even with the trailer.

I even pull at 55 in OD, just be sure to unlock it or drop to drive-3rd- if accelerating.

Sir to tow like that wont limit your warranty? I wish I could get by doing that, Jimk
 
Back to the converter slipping, if it does slip and do so when I'm at say 750 HP doing a 2-3-4 locked shift would the heat of the converter dis-color or burn the paint on the converter.

What was the question??

O. K. , I think I have seen one post that actually answered my questions.



I left my sig out of the first post for a reason: I already have an aftermarket TC and VB, and they are getting tired. No 2nd lock-up, shuddering, high temps, etc.



Last week broke an input shaft, now need a rebuilt/ new trans.

I have not been dissatisfied with my current setup until recently.



I'm not going to drag it anymore, or sled-pull. I just drive it everyday, and tow +22K occasionally.



So, Back to my original question:

HOW DOES EACH ONE DRIVE? (that's right, I'm shouting now)



Four pages of Bull****, and only one informative post!
 
Blue Thunder,

The number of converter clutch disc has absolutely no effect on the fluid coupling mode. So drivability between a single or triple disc converter would not be any different provided both had the same stator/ pump configuration. The advantage of the triple disc would be durability. With diesels I believe it is always better to have a little more than you think you need. Hope this helps to answer your question.

Its hard to say how each one drives. I will only comment on the dtt as I have never driven the other brands. Drive-ability also depends on the model of converter. I daily drive a 89% and it does a good job of letting the turbo spool up even with a heavy trailer. I also have spent many miles driving a 93%. Works great driving around empty but getting a heavy trailer moving can be a little tricky. As far as the tc lockup, it is less needed in a 93 than an 89. In the 93% truck I usually keep it unlocked unless I am cruising on the highway. I plan on using a 91% on my next truck. I really dont think you can go wrong with any of the brands, they all make a night and day difference from stock. My biggest concern would be choosing the right installer. Good luck

"This was my experience with a very tight converter. I loved it on the track, but everyday driving is sucked way bad... That is why i made a multi disk with 4 friction surfaces. "



A tight single disk that using fluid coupling to save the lockup clutch is awesome on the track, but for everyday driving its a little challenging getting the turbo to spool. Especially if the spiny deally is a big lag monster.

Answer: I've had Suncoast... . still do... in boxes... . I now have a full Goerend Brothers transmission. I'm not putting down HUGE power. . but I'll find out exactly tomorrow. My transmission shifts smooth all the time. No hard shocking shifts. Lock up is solid and will not slip. The stator in the converter is a custom (and patented) design, starts out tight and gets tighter. Great for towing, great for racing, great for pulling. I have NO complaints about this transmission. The soft shifts I don't have to go with a fully billit trans because I won't break the factory parts. Won't break because I am not SHOCK loading those parts when it shifts. Smooth. More info on the other company... PM me.

Sir if I have lead the question off the path I did not intend on doing so. I just wont to know what it takes to have a good towing converter that has warranty. I am not going to spend 4k or 5k to be my own warrenty station. Nor am I going to mislead the manufacture my intention of its use... If the convertor and the transmission will go to lockup at 1500 and pull a trailer and hold, great. The idea of you can do that and it will probably work, but you are on your own is not for me. . jimk

That's funny:D I knew that was coming!



I researched this a while back myself and just like you was interested in daily drivability and just like this post it turned into a-who's the baddest and focus on lock-up mode.



I made my decision based on lots of factors but one that seemed good was asking myself- lock-up aside, which one would I like in conditions where it was unlocked?



I believe heavy footed drivers that drive em like they stole em are better suited with one that is more loose (unlocked). They like the feel of the RPM,s up there where power is awesome, shifts and lock-up come sooner for them when into the go pedal.



Light footed drivers on the other hand seem better suited (while in unlock conditions) with heavy fluid coupling as they chug along in the lower R's with shifts and lock-up points streached out.



This obsevation again is based on "daily driver" stuff.



Both styles see race duty and everyone is happy with what they go with and I am sure its due to being miles ahead of stock in all driving conditions.

Jim your so politically correct;)





Kevin, I think you will like the 91, every once in a while I wish I had my 89 back(maybe 5% of the time) but like the 91 the best overall.





Anyone going to answer my converter paint question

I don't know what type of paint was used or at what temperature it will burn? Some questions just never get answered like warranty? jim

Josh,

Yes you purchased a Sun Coast single disc approx 2 years ago.

When you seemed to think you had a problem I offered to warranty the converter if you would return it. You would not give the supplier the opportunity to remedy a problem or even determine what the problem is. It seems you would rather keep it in your box, this way the real answer will never arrive and you have something to post and ***** about. People who wake up each day looking for a reason to be offended are never disappointed.

Ok maybe 2nd place - I have been following this knowing where it would eventually end up;)



I can honestly tell you I went with SunCoast because they are about 2hrs from my home and "IF" I had any problems with my transmission I would be a short tow away... . So far so good.



It's not hard to build a better transmission than DC:rolleyes: LOL

What is all the talk about hard or soft shifts? That has nothing to do with any builder. The vb can be setup to shift hard or soft. My 97 I ask for it to be really hard. Many times people that ride with me will ask WHAT is wrong with your truck. It shift like a rock. But that is what I ask for. My 01 which is my wifes, has a nice soft shift. But that is what she ask for when that one was built. And yes thay are BOTH DTT single plate tc trans.
