: Torque Converters: Single vs. Triple
cdhd2001 11-24-2004, 02:18 PM After doing some reading, in particular Trippin's latest converter thread, I have a few questions.
Does the single disk feel "looser" than stock?
Does the triple disk feel "looser" than stock?
Which one has the "best" feel for a daily driver in city traffic?
Also, in a recent post, Diesel Tech/TTS said that the single would handle as much as the triple. Comments? :confused:
Mike L. 11-24-2004, 02:56 PM The triple will hold more than the single. Spend the extra money and you will sleep better.

Kennedy 11-24-2004, 05:00 PM Single or triple has nothing to do with the fell driving around town. The TCC is not locked unless in TH mode.
As for single vs triple, the triple is said to have significantly more holding capacity.
Mike L. 11-24-2004, 06:43 PM I've tested quite a few Allys that lock up at 1/2 throttle in 2,3,4,5 in the OD position.
Carbon04 11-24-2004, 06:50 PM I have had the TTS triple installed for about 5K miles now. I have driven other DMAX's with Suncoast and ATS triple lock converters and I have to say that I think the TTS is the best of the bunch. I have A LOT better throttle response and low end pull with the TTS than stock or the other triples. It is a handfull to drive in the rain though with the new converter even at stock power levels.

At what RPM does it stall?
Mac
Carbon04 11-24-2004, 07:59 PM As per tech2 flash it stalls at 1750rpm....................about 100-150 lower then the rest. At 60mph in 4th gear when selecting lockup in the tech2 rpm's drop 150rpm. Thats tighter then any other DMAX converter I have personally driven(Suncoast triple, ATS).
Diesel Power 11-25-2004, 12:59 AM I'm getting my TTS triple day after turkey day. I'll post some comments when i have them. i've driven quite a few suncoats, a tts single and dmax_doug's tts triple.

Define stall. And how you want it tested.:D
Mackin 11-25-2004, 07:36 AM Define stall. And how you want it tested.:D
If you got the leg!
Right foot go,left foot stop.Give'r all you got! When the Tach stalls,take a reading off the Tech II!
If your not weak in the knees put it in 4x4 and don't waste the spool up!Yeee Ow! Ever done it? It's vicious! Hello Super Diesel!

Sounds like the way I launch/race it at the drag strip. In 4x4. :D
Somewhere around 20 psi of boost I start to hear a whirring noise, not sure if it's a tire spinning or the Allison and converter screaming for mercy. :eek:
DOGBOY 11-25-2004, 07:08 PM mackin,
i was told as a kid to never ever ever do that, was told that it would cause tranny to fail real fast. is this true or do people just not care?

I'll try to answer that...........the transmission upgrades that many of us are running can withstand quite a bit of punishment..........it probably is not the best thing to be doing..........but man is it ever fun............):h

After that explanation I'm sure all these guys will stop doing the high stall launches under big boost. ):h Maybe they will take up needle point.-:t I have my money on the big launches.:ro) :D

Kennedy 11-26-2004, 10:14 AM I may be mistaken, but I understand TCC lockup to be based on output shaft speed which (depending on tire size) is directly related to approx 22mph in TH mode, and 52mph in normal mode. There may be some alternate programming, but most of the time I've only seen it come in at around 50+ mph.
I've tested quite a few Allys that lock up at 1/2 throttle in 2,3,4,5 in the OD position.

Braz,
The Sun Coast single disc has a HUGE clutch. I have not seen a power level it could not handle. Of course 99.9% of the trucks making big power opt for the triple. There is a definite difference in the "feel" of clutch engagement, the triple being a lot more pronounced. The single still has a billet cover and almost double the factory clutch area,and the same fluid coupling. Your choice.
Thanks,

How many converters have you actually driven and tested? Do you even have an aftermarket converter? Do you think we need you to remind us which post to read? Joe at Suncoast builds a great converter, I have sold and installed plenty.ATS does a great job also. They all have their place . TTS has a new converter that does give more low end power and quicker turbo spool up. ( torque multiplication). Watch the big boys start changing things. This is good for the industry and consumers in particular.

Bronco 11-27-2004, 12:09 AM Let me regress for I have ofended the TRANSGOD!
Mike I was just helping a fellow Place member answer his question about the feel of the different converters. The past post came to mind so I went back and pulled it up. I didn't author the original post and made no opion on anything. I was merely passing information along, trying toi help someone out.
Now that you have me thinking about things I will add my own .02 cents.
Mike you are so phony! Not to long ago you were singing the praises of Suncoast anf your homy smoop. Now you have your own product to pedal and anyone or anything that comes between you and your wallet gets a tounge lashing from you.
Don't you need to go talk to your employees now? The ones who actually know how these transmission work and the ones who actually know how to R&R these things. You just pay the bills right!
Diesel Power 11-27-2004, 02:55 AM Bronco,
i don't mean to interject but here i must as your timing is well, perfect. This morning Mike tore my tranny out to install one of Steve's new Triple locks... Steve and I stopped by to see how it was going, and guess who wasn't sitting in the office smoking a cig- Mike.. He does the work himself. Sure he has some guys to help, but he's far from a paper pusher. he's the most allison-versed person in the shop and the one who worked on my tranny both times.
I was going to wait to post this until i got back home, but i was really curious so i figured someone else might be to- Mike installed my transgo kit, replaced C2 and C3, and installed a TTS converter 1 year and 22,000 miles ago. Since then i've beat the hell out of it, ran may passes down the track and ran 2 sled pulls. I was convinced my clutches would be in pretty bad shape. to my surprise, C1, C2, C4, and C5 looked brand new. C3 had just a tid bit of color on about 10% of the cluctch material of two of the frictions. that's it. Had i known how good a shape it was, i would have just had him throw the converter in and not bother pulling the clutches.
Sorry to take this a bit off-topic, but Mike has always gone the extra mile to take care of my tranny inlcuding calling me at 8:00pm to see how it was doing. The only thing i'd change is move him 6 hours closer to Sacramento.

Mike L. 11-27-2004, 11:01 PM Bronco
I am a Suncoast dealer and smoop is still my friend. I recommend Suncoast products every day to people. Their products are great and I use them in my shop. I do not talk people out of Suncoast products as I do not talk people out of TTS products. Same goes if someone is looking for an ATS product. Steve Cole at TTS has developed a new muti-disc that has some kick in the pants tq multiplication. I like it, and I have tested it in competition. As everyone that paid attention noted that I kept pretty quiet about it when the anouncement was made and the testers were allowed to break their silence. I walk a very fine line here, and I will never hurt my supplyers. I will test new products and give my opinion as they come out. As far as me not knowing anything about transmissions; ask around. As far as the money goes; ask around some more. BIG DIPPER was correct. You are a jackass

The TTS Triple Disc IS pretty sweet. I do not have anything to compare it to, but my truck with NO tuning, stock muffler, stock intake, is very noticeably quicker with it. And 0.9 seconds quicker in the 1/4mi to boot.
This is just my experience. Take it for what it's worth.

Kennedy 11-29-2004, 10:33 AM Just in case anyone is having trouble following the real posts here, I'll try to expand a bit.
Single or triple, you will not feel the difference when locked up. You MAY feel an apply difference depending on apply rate, and friction capabilities of the converter. The only way you'd know the difference when locked up is if one were slipping. Running in TH mode, the TCC will engage early on at about 22mph depending on OSS and remain engaged in all gears.
In Normal mode, the majority of your driving will be in the unlocked mode. Now in the unlocked position, we aren't dealing with the clutch, single or triple etc. We are dealing with the fluid coupling and TQ multiplication. I'm not an expert in this area, but I can tell you many need something "tighter" to work the engine more when unlocked. This is primarily a function of stator design. I know for fact that Suncoast and ATS have "tighter" stators, but tend to shy away from them for the masses, as many fell that the truck gets lethargic, and cannot spool enough boost, or respond quickly enough. For those who snowmobile, it can be like when you put in some really heavy weights, and miss the mark by a gram or two. Too light, and the opposite will occur. In my case, my engine runs at 3k or better when the TCC is unlocked so I need to tighten it up significantly. This can be observed by accelerating through the gears and watching the RPM drop in Normal mode as well as TH mode. Keep in mind that around 52mph, the TCC will lock in normal mode as well.
Right now, my 2002 is on the hoist with the transmission out and waiting for the next tighter Suncoast converter to be installed. This is the one that Joe twisted his driveshaft off with a few weeks ago. First I have to finish my turbo work. as no better time than when the trans is out! Having the second truck now allows me to take either down for an extended period of time so I can work on them as time allows...
cdhd2001 11-29-2004, 11:34 AM Kennedy,
Thanks for the excellent summary!
cdhd2001 11-29-2004, 11:39 AM Okay, here is how my question should have been asked.
Which converter, single or triple, and make has the "tightest" stator? This is in regards to purchasing off the shelf, not having them make a custom job.
Personally, when unlocked I feel that the stock converter is way too loose. This is comparing to my 1994 350 tbi with 700r4 (yes I know, apples to oranges comparison).
Diesel Tech 11-29-2004, 12:04 PM The problem is not making the converter tighter, that's simple. Torque multiplication and fluid coupling are what's needed. Torque multiplication is what gets the vehicle moving and helps pull the load. So if you tighten the converter and give up torque multiplication the vehicle feels terrible, this is what most converter manufactures have done. We spent a lot of time not to do this, we have better than stock torque multiplication and lower stall speed which is the best of both worlds. This is what all the TTS customers are feeling in our converters, single or the new multi-plate unit.
Mike L. 11-29-2004, 01:21 PM Kennedy
Why do you think your converter needs so much more tightness than others? Don't know what you are doing with your turbo, but if you are going bigger you are looking for love in the wrong place.

Kennedy 11-29-2004, 01:40 PM Brake stall = 2900+ with the tight unit that the Dodge guys use...
