I just wanted to let you guys know I called and talked to Don today. He was very kind and knowledgable and great to talk to. If you guys have any questions about any of his products, turbos, trannys, etc. , I think you should give him a call. I still don't know what TC I'm going with, I stil have to talk to Bill, But I'm not counting ATS out. They can make a TC any % you want. Just thought I'd share that I feel they're a pretty good company that's honest and not disrespectful (I dunno if any on TDR aren't honest or respectful... besides the 2 we all know about, Banks&DR. P) and it was definately worth the call.

P. S. It kinda sucks that there's a 2nd player in the TC field, I was hooked on Bill 100%, but now I have to admit... I may be swayed.

Hey POWERWAGON, I've been told in my research to convert my Ford to a Cummins with the 518 transmission and the best route to go is to convert the 518 to a lockup convertor. Apparently it does entail a few modifications.



1. another spacer between the engine and the trans just like the spacer that you already have, with just a small amount of modifying. OR, you can get the spacer from one of the newer transmissions (auto of course), which is exactly twice the size of your existing space. With this you would either have to use the late model starter or redrill a hole for your old starter to line up.



2. Use the later lockup torque converter.



3. Add one more wire to the existing wiring for the overdrive.



This conversion is per Little Transmission in Mesa, Arizona which is the next door neighbor to Randy and Reliable Diesel.

Like Jim, I'm interested in the construction of your stator. My truck has an older BD TC that the previous owner installed. Everything is still in good working order but out dated do to advances in technology.

I am aware of the loss of efficiency at higher rpms do to the milled stator in my converter.

I don't mind towing while locked up, but while accelerating I would just as soon use the fluid coupling. Makes me a little nervous transferring the shock of such a torque monster without some give. Unlike some of these guys, I can't afford the downtime and cost of replacing broken parts. :eek:

Any more education you could provide would be appreciated:D
We make stators for many different fluid-coupling applications. We use three different types of material, 4130 steel, 5356-cast aluminum and Billet 6061-T6 Aluminum. Earlier custom stall speeds were built out of steel, they are now CNC machined out of aluminum. We prefer aluminum over the steel construction due to the weight savings. A steel stators weight is about 8 pounds while our aluminum stator is about 4 pounds; we felt the lighter stator would be a little easer on the stator support (Pump Shaft). The aluminum stators have been rumored to be week, we have performed extreme test on designs that are 50% thinner than the stator fins we use, we had no failures. Also we CNC machine the cover out of billet steel. The piston & drivers inside are also CNC billet steel. The three lock-up clutch plates are laser cut from soft metal so they won’t ware into the drivers. The turbine & Impeller is furnace brazed. If anybody has any other questions please call us. As far as pricing please call 303-431-7973

Stopped in at ATS yesterday afternoon and talked to Don. He showed me around the shop and explained how the new converter works. He spent about an hour and a half talking with me even tho they are very busy. They do everything in-house, they can build the converter for the application. He let me drive his truck and all I can say is :eek: :eek: :eek: :eek: :D :D :D :D and then some, man that thing runs. I was very impressed with how the converter works. Nice smooth gear changes, lock-up in each gear, that's very nice when slowing down. Works great with the exhaust brake. There wasn't enough room to run it out since it was rush hour but I could feel how it works just fine.



Thank You very much for your time Don and yours too Clint.
 
A lot of people on this site need to chill out. There is way too much "button pushing". I have left this site for months at a time simply because I got sick & tired of wading thru all the c***. There are some extemely intelligent people here & the people who clutter up this educational opportunity should be taken out to the back 40 & disposed of. :D



In the world of mathematics & engineering, there are many ways to skin a cat. None are incorrect, if in fact the desired answer is indeed achieved.



Kudos to people like Bill & the many many other valuable TBR member resources (too many to list here) who spend the time (yes, this does translate directly to money) & have the patience to educate the various technological skill levels present here on the TDR.



Not all who have the desire to help educate, have the time nor the opportunity to do so. One can not & should not be flamed for this.



Internet is big & internet is important.

Internet was orginally intended for the sharing of ideas between scientists.

If it gets so cluttered up with banter & hostility that we can no longer educate each other in a mature & responsible manner or even find the answers in a reasonable time frame,

WHATS THE POINT?!



I have been down to the "new guys' shop (ATS) many times. They do indeed have a passion for what they are doing & I believe that they are also very good at doing it. They have gone out of the way to help me & also educate me on a number of things. And, I appreciate it. I too have riden in Don's truck & I'm not even a slush box kinda of guy. Never-ever liked ANY auto. But ATS's is most impressive. Impressive enough to make me consider one for a new vehicle purchase/mod? Yes. Absolutely.

Give these "new" guys a chance & let them prove themselves.

I think you'll find that they are really not so "new" &

I believe you won't be dissapointed.

Price?

If these guys are on the same playing field as the other transmission guys why don't they answer e-mail about their prices?
 
IMHO, that ATS does not currently have the resources to devote the appropriate amount of time to e-mail & the internet media.



Remember, these guys are very busy developing their product & servicing existing customers with a hands on approach.



I find it best to call Clint or Don on the telephone & bend their ears a little.

I have sat back on this thread and observed. It has been an interesting couple of weeks of reading for me. I have taken numerous phone calls as to why my silence.



What really bugged me was Chris Strickland. Here was a kid with an engineering degree with a basic understanding of the automatic transmission and he also understands the basic concepts of the tc. I have given Chris a hand in the last year and a half, nothing serious mostly technical support and he was on his way to visit us and to stay with my family for a week.



On his way here Chris thought to stop off at ATS to check them out and see what they had to offer for his truck. I guess he was intrigued by their post and also by my silence to their claims.



The kid also had the nerve to tell me that his lock up clutch was slipping and felt theirs would be better than mine as their multi disc system would have a higher holding capacity.



Talk about guts, to come into my home and tell me that.



I found it amusing and somewhat disturbing that he would think such a way considering his background. If Chris was thinking this way based on the post and the wording what was the average consumer thinking .



Are tc’s and their function really that much of a mystery to the average consumer.



I knew there was really only one way to prove to Chris the truth about lockup systems and how they work, their strengths and their weaknesses. I would let him do the diagnostic work himself and form his own conclusions.



I had him hook up a mystery switch to prove to me that his lock up clutch was truly slipping.



With the switch engaged I had him beat on his truck, we did this for about ½ hour, I took a cell phone with us . One on one Chris looked me right in the eye and said look at the tach Bill, I can prove the lockup clutch was slipping.



The tach was coming up and the vehicle speed was slow in reacting. Something sure was slipping, he was still willing to bet it was his lockup clutch.



He took the transmission out , and we went and had the tc cut open , I wish I could describe the look on Chris’s face when he discovered the lockup clutch looked brand new.



He opened up his transmission next, found third gear smoked out of it, and 4th gear on its way out.



I think Chris finally saw my point, the lockup clutch on any transmission is weak at the low rpms, I don’t care who’s system you use. Any claims otherwise, just consider it good marketing with no factual basis.



Now if ATS had compared their product to factory or to some of the other competitors rather than DTT this would be a non – issue for me.



However, since we seem to be the company they have chosen to compare their product to, I just wish they wouldn’t have done it with lies and innuendos rather than actual facts.



Lets see, the steel stator weighs 8 lbs, hmm, they didn’t say it was DTT’s that weighs 8 lbs, just that a steel stator weighs that much and could damage the pump stator.

Interesting, if that is the true weight of their steel stator I can certainly understand why they had so many problems and had to switch to aluminum.



Lets see , the other point , you had to increase line pressures to improve shift feel for some people. That is kind of funny if you are a transmission technician. A first year trans tech can tell you increasing line pressure is not necessary to get a firmer shift.

Once again, that simple comment speaks volumes to me.



It is apparent they do not understand, but they were at least smart enough to follow my advice and have Kevin Goode’s pressure set at 96psi at an idle, almost double factory.



With those kind of pressures even a factory lock up tc can handle the kind of power Kevin’s truck is making with relative ease.



If they really wanted to prove a point they should have set Kevin’s pressures at factory levels to prove how good their lock up clutch is.



Then they also tried to teach me that the Ford’s lockup pressures are regulated from the factory, well gee, everything from the factory is regulated that is why aftermarket companies design and build their own systems, once again their words spoke volumes. If getting around factory regulated systems was an issue for them, I am not going to educate them , believe it or not guys I make my living getting around factory regulated systems everyday.



The best thing of them all is that they want to compare their lockup to our fluid coupling.

This is the same thing that Suncoast, BD, Dunrite, Protorque, and the rest of our competitors are trying to do.



I find it fascinating that all of them now including ATS want to compare their lockup to our fluid coupling. Why is that ? Look at their ad’s , they all say they have a better fluid coupling, some claim to have 96%, some even 98% , impressive isn’t it?



You would think with those numbers all the above mentioned companies would want to compare apples to apples, ie) fluid coupling to fluid coupling or lock up to lock up.



Why my silence you guys asked, while I will always try to assist the tdr members with their questions and problems, however I am not here to educate my competitors.



The majority of our customers are towing heavy and just looking for reliability, durability and drivability but that does not mean we aren’t competitive in the high hp games.



Don, Clint, no offence meant here, if you guys want to compare to us then bring it on.



May Madness or Muncie or both, we will be there, fluid coupling to fluid coupling, lock up to lock up. Pick a hp # , 500hp, 600hp, 700hp , and don’t be surprised to even see 800 hp, we don’t care just let us know which one you want to go at.



See I have noticed lately comments or questions asked by DTT customers or myself is considered to be flaming the competition. Yet throughout this entire thread ATS seems to want to compare their products to DTT’s, and comments from me or my customers are flaming. Interesting how easy it was to confuse & mis-lead without challenge. Maybe now some of you guys can see how easy it was for Dr. Performance to get the level he got to, no one challenged his claims so what he said must have been be true right?



Don & Clint if you want to have free advertising without comment from us then might I suggest you don’t use us as a comparison.
 
I think I still want DTT

ATS might be great for guys like KATDIESEL(or any of the other super HP rams out there) who have race trucks. I am 40 years old pull a 5th wheel and all I want is a transmission that matched my needs with one added feature RELIABILITY! I want a little more performance. . (edge ez and 4 inch exhaust) and I'd like that performance boost to go to the ground... . in comes DTT. I also want the transmission to be fixed right the first time and from all I hear thats still DTT and should something go arye then again in come Bill K to fix it.



I think I want the 89% TC and valve body from BILL K and this summer I am gonna find someone in the south GA area to put it in for me... . cause I know if there are any problems Bill will make it right
 
Good to be back

I have been busy the last few months and have been away and its a joy to come back and read the TDR again. I am no expert or transmission guru but I have about 52k on my truck already and about 30 of that has been with DTT TC and VB, I have pulled about 4-6k almost every mile with my truck and Bills VB and TC has not failed me at all and I would never look to go to another "vendor" other then DTT. Have I ever tried any other TC? No... . Is there better ones out there??? Maby? All I know is that my system is a kick *** set up I have now and I am happy, if alot of people are happy

with a certian vender then why not go with that one? You tell me till your blue in the face how good your product is I dont care... The only reason I bought from DTT in the first place was because of all the feed back from others and all the positve remarks I heard. Customer Service is #1 for me, the product is #2. I think I got the best of both worlds with DTT. :)

An excelent repy Bill,

I met Chris at James N's shop outside of Dallas last Feburay, and helped him pull his trans out that cold evening so that you all could rebuild it. The thing was smoked then also, and my first impression of Chris after working with him for that 3/4 hour was that this young man has what it takes. He has Guts, and displayes pure honisty in his personality, and as a father of 8 kids I feel that his parents must be as proud of him as I am of my Kids.

Oh Yea as soon as I can get my Daughter settled in College I'll be needing a Trans upgrade also
 
Oh, Oh:rolleyes:



Sounds like the thrilla in manilla is all set for May Madness or Muncie.



All I know is this;



1) After trying to follow the rheteric on automatic transmission features, I almost sure I know even less now about autos than I did before.



2) I'm sure glad I don't own an auto:D



3) NOW... , I might be motivated to go to one of these May Madness things. Everyone loves a good fair fight:eek:



BTW,

Merry Christmas to everyone:)

perspective

Having read this thread to this point I feel the point has gotten lost. While ATS may have a good converter, is it really necessary for the masses. It may or may not be a better mousetrap. This has been tried before without the fantastic results expected. It seems one of the biggest claims for the ATS is how lock-up will hold while you lug the engine! Having been in the trans business for over 25 years, I do understand the workings of lockup. I also know that engine speed is pump speed and while pressure is produced at lower rpm volume suffers as the pumps are positive displacement and thus less rpm less volume. To maintain line pressure the regulator system will tend to take from lube. Bill has taught his customers as have I to keep the rpm up on their engines. This helps the engine as well as the trans. It was mentioned in an earlier post that setting the line pressure up would wear out the crescent in the pump. This would be hard to do since the Dodge(nor the Ford) pumps have one. The Dodges and the Fords have a gerotor type pump not a gear and crescent. I have seen pumps in the Dodges with 100k that with proper maintenance and good fluid had no measurable wear in the pump.

Having installed most of the converters available in customers trucks I have to say that for the vast majority the DTT converter has and will hold, and last for what it is used for. Just a few thoughts. Sorry, for the long post.

to start off with. . I've learned lots from this thread. I have a 6spd in my truck but I've bought a truck for conversion and am considering an auto so my wife will enjoy it more.



I gather that ATS started this thread to toot their horn about a new TORQUE CONVERTER and then we all got off on the entire transmission.



I gather that their claim to fame is not the multi-clutch idea but the heavy duty billet housing that can handle the pressure to keep the clutches from slipping.



I haven't heard anything bad about any of these guys (ATS, Bill, Fred... ). I like the experience and reputation of DTT, but why can't we notice ATS for the promise that their TC holds. If a stock piece behaves as they say (ballooning) then their TC is a better mouse trap. Multi-clutch seems to be the way to go. Everyone who builds trannys seems to increase clutches in the transmission and increase fluid pressures, so more clutches and the abilty to handle more pressure in the TC has to be better.

Mark,



That is an interesting observation,

It is amazing the subtle little things people pick up on that stick in their mind when choosing a product.

The thing is ATS put that stuff out there and it is technically flawed information. Now whether it was put out that way deliberately to mis-lead or they simply dont know better is debatable.



As James pointed out pump volume is directly related to engine rpm. On a typical drag car almost every tc has an anti ballooning plate on it, to help prevent the tc from ballooning . It does not always work but most of the time it does.



On my own personal tc in my racecar i can tell you it does have an anti-ballooning plate on it. So why didnt i put one on the Dodge Cummins Diesel when we designed this tc is the question one should be asking. It is not because i am unaware of balooning plates.



The answer is quite simple, lack of rpms in the Dodge Cummins Diesel. There just is not enough engine rpms to worry about the tc ballooning.



If putting a big front cover was going to solve the lock up clutch problems Suncoast would have dominated the market and i would not be in business today.



Adding rotating mass to the converter is definately going to cause other problems which eventually will lead to tc clutch failures.



Lets just say i have done a few Dodge tc's in my time and these are words i do not use lightly, " i have never , ever , replaced a tc because of ballooning, not a factory one and not one of mine"



The need for the heavy front cover is a marketing scare tactic companies use to sell products as it sounds reasonable. Once you guys do a little homework and understand why a tc would balloon in the first place it wont make sense to you to add a heavier front cover.



Think about it now, if you add more rotating mass )ie a heavier front cover, is it going to affect your engine bearings and transmission pump bushing?



And if it does affect your transmission front pump bushing wouldnt that in itself prevent the tc from ballooning as you could no longer seal the oil inside the converter .



Since the tc clutch is located inside the converter would the worn out pump bushing not allow the tc to be fully charged. It would be the same as if you had a leak in a hydraulic ram. Would that limit the amount of work it could produce? Would that not also lead to tc clutch failure?



People often wonder why we replace a lot of Suncoast tc's, its always the same story. Pump bushing is always wiped out at the 7 oclock position if you are facing the transmission.



If you guys take a few minutes and look in the tdr magazine, you will notice that dunrite has been selling a multi-disc clutch for awhile now, they too do not seem to having a ton of success with it.



The clutches inside the tc are different than the clutches inside the transmission. The principals are not the same as to how they are applied.

Very good post Bill and James,

I like posts where people show information instead of bashing, You see most of use do not know anything about auto trannys (other than it makes our truck move in direction), if some one runs us through point A-B-C-D-E then we understand it rather than someone saying point A-E and that makes it the best. Running through all the points is time consumeing but to most of us thats the only way we can relate. ;)

Thanks again,

Ron
