I first want to apologize to all of you that have been waiting for my response since I went to Colorado for the transmission swap.

For those that didn’t know, in my never-ending quest to reach an 11. 01 e. t. and more consistency in drag racing, I took the leap to the “other” side. That’s right, I took out a perfectly good 5-speed NV4500 and replaced it with a 47RE equipped with the ATS Diesel TripleLok torque converter.

I had been talking to several people, explaining the fact that I broke two transmissions within 1 week and I felt that an automatic might be the way to go. Piers Harry of Piers Diesel Research told me of a company named ATS looking for someone to sponsor. I hadn’t heard of them so I did not act upon the suggestion. Next time I talked with Piers he said he told Don Ramer at ATS about me and that I should at least call them and see what they had to offer. So after many conversations with Don Ramer and owner Clint Cannon, I decided to accept a sponsorship and planned a trip to Denver. Briar Hopper (Tom) agreed to accompany me to help with driving and to learn about automatic transmissions for his future venture.

Don worked closely with me on getting all of the parts and pieces together for the conversion. In hopes that this may soften the blow of any problems we would encounter.

A thread on the TDR discussion forums started about a challenge that a manual will flat out put more power to the ground than a “slushbox”. I thought my situation would be the perfect opportunity to prove that manuals could put more power to the ground by dynoing the truck prior to the swap and then right after we were done. I mentioned this to Don and he promptly scheduled me in to a shop with a dynamometer.

Tom and I arrived at ATS early Monday morning and Don arrived soon after us. He introduced us to the “purple crew”. I was amazed to meet not only a couple, but over a dozen transmission experts hard at work. When I say hard at work, I mean HARD! This shop is so busy with local business it’s a wonder that they have time to breathe! By walking into the showroom you would never know it, anyone of them will do what it takes to answer your questions. Whether you are looking for that 700R for your hot-rod or just a little tweak for your hot-rod hauler, you will find it and answers for all of your questions at ATS.

Clint started business in his garage back in 1991 and has worked diligently over the last 10 ½ years to make the company what it is today. Nowadays you’ll find an eight-bay shop, full production line for the converters, the transmissions, and the valve bodies. I figured out that Bob, an older gentleman found at the end of the production line upstairs, has the best job, he bonds the clutch surfaces with glue and a space-age material. They don’t even pay this man, he is so high on glue by the end of the day, he doesn’t need any money! LOL. Seriously, they bond all of their clutch surfaces in house. I don’t know if this is a standard, I know it impressed me. Truly a class-act operation of which I can say I have never been in a shop with such high morale as this one. They all contribute in making the product better, that’s evident. So when you look at their product, there are many faces behind it along with many late nights supporting its growth and development. After the tour I anxiously left to go dyno my truck at MPG Heads.

I arrived at the shop and after two hours Scott had my truck hooked up and ready to go. The dyno was a wheel dyno so it was necessary to remove my tires. After a dozen or so attempts we could not get the dyno to perform the pull down and the owner reluctantly set me on my way with no dyno numbers. (Side note: good thing because I found out with SAE correction I would have been over 1000hp LMAO!)

I made my way back to Wheat Ridge to the ATS facility so we could start the gruesome task.

In the meantime, Briar Hopper had been busy, learning how to assemble the valve bodies and the transmissions for both the Dodge and the Ford. He was really pumped as he showed me how slick the valve body modifications were, and how much fun it was to do them.

Don introduced us to the TripleLok (trademark protected) and I quickly understood why they were so confident that it wouldn’t slip or destroy transmissions. Tom and I asked Don many questions and he was great at answering them so a couple of manual guys could understand. From an engineer’s schematic (Clint with a napkin?) to the customer’s automatic transmission four years they have been blueprinting this converter. Many trial and error attempts with Clint, Don and the rest of the crew holding their breath just hoping that this is the one.

Moving on to the install; Ian Laughlin, an ex-Marine, was assigned the monumental task of switching the transmissions. While he removed the manual, Tom prepared my transmission and valve body. Like everything else with my truck, things did not go as planned and an inordinate amount of time was spent on little things, like the Lokar shifter. This piece looks so nice, but was not worth the hassle that Tom and Ian went through to get it to work on my truck. Despite the tough time and my moaning, Ian stayed late every night to do a superb job on the install. Thanks a million Ian!

We didn’t get the truck fired up until Saturday night and to no prevail could we get the dash to work. We did find out that the 1998 12 valve only uses that year’s PCM. So after much frustration, Tom and I had no choice but to drive back to Indiana with no gauges. Shortly after my return Don shipped me the Snap-on scanner so I could monitor progress as I installed the brand new PCM. Also a few more tweaks were necessary with the TPS along with the cable.

I have very little experience with an automatic transmission to speak of so if I don’t cover something important to an automatic enthusiast, please ask. I also do not know what the “standard” is for automatic tolerances so please bare with me. Obviously it feels like the truck is going into orbit without the break of the clutch. This transmission grabs the next gear and keeps moving forward. I feared turbo lag, and a “slush” start due to my 3. 55 gears coupled with 35” mud terrains. No such thing, the truck takes off and doesn’t look back. Lockup occurs around 30 mph whether I am in 1st or 2nd gear and it stays locked up through all of the gears. When I really laid into it, I finally familiarized myself with the term “torque steer”. The neatest thing I have experienced with the lockup is downshifting. You heard right, this converter stays locked up and downshifts through the gears. I rode in two trucks that were also equipped with exhaust brakes and this is just phenomenal.

I installed the new PCM, which finally gave me my dash back, but I lost lock-up, so I spent all morning with Don and Clint diagnosing this. David Lovell even lent me a hand as I searched to no end for part numbers. Clint and Don have a couple more things to try so I will get this fixed soon. I decided to test and tune in fluid coupling only but as I posted in the competition forum, the track did not open. Luck has got to turn for the better eventually. Keep your fingers crossed for me!

Where can you find this great product? Well, you can reach ATS on their new website, or call them on the phone. Briar Hopper is in the process of opening a shop in Cynthiana, Kentucky to service this side of the States. He hopes to open “Black Mountain Diesel” in early May. I want to thank Don, Clint, Tom, the ATS crew, BJ, Tom, Tim, Eric and Bill Swails (Earth Roamer) for all the sacrifices they made for me. Feel free to ask me for a ride when you see me!
 
Great post Eric. I hope you have a little better luck in the future though!! Sounds like Murphy had your number for a while there.



Keep us posted on how your transmission performs and what you think of it.
 
Great post! Can't wait to hear all the results from the track.



Just makes it all the harder to decide who to choose, DTT, or ATS. :confused:

I loved driving Eric's truck home from Colorado, quite a difference from the 5 speed. I also enjoyed driving Clint's TripleLok equipped Ford Powerstroke while I was out there, it was awesome. (Thanks, Clint)

I must admit I was skeptical in the beginning about the torque convertors(but I ALWAYS keep an open mind), but one look at the demonstration unit they had, and the engineering ingenuity that went in to the product, simply blew me away. One of the most exceedingly clever mechanical inventions of the century. Sure, I'm laying it on too thick, you say? No. I'm not easily impressed.

The bad part is, as much as I love my own 5 speed, the whole experience made me regret not having bought an auto-equipped Cummins Ram instead. So, hopefully I'll be able to get a second truck someday soon, and it'll have an auto in it... .

The whole experience with the Lokar shifter and having to fab it to fit, wasn't so great. Fortunately, Ian and the other mechanics were highly competent and easy to work with, and we did get the shifter re-worked without compromising it's strength, looks and function.

That is one of the nicest secrets behind ATS' success, they have an incredibly talented staff, it's like a family in that shop. We WORKED but we had fun, too. I already miss Colorado...
 
Good post Eric. Thanks for taking the time.



I have one question. You said lock up occurs at about 30 mph.



Is that true for both light throttle shifts as well as full throttle?



Either way, I wish you luck and your 11. 01 et too.



-Chris
 
A long with Strick-9, I see where this occurs no matter what gear your in. And It also holds lock up as it downshifts through the gears. -- I did not think this was std PCM programming. Do they have some kind of add on controller that does this?
 
Slybones,



So yours does it too?



It sounds like an engaged Autolock to me. Basically a mystery switch with a cutoff at a preset speed (<30mph).



It would take some custom valvebody tuning to allow locked up downshifts. I'd like to drive one of those trucks just to see what it feels like downshifting in lockup.



Do all of the ATS transmission's perform like this?



-Chris
 
STOP!!





I don't like to here this kind of talk. I see that I am going to have to hire some sluggs to pay ATS a visit. SBC will not tolerate anybody converting the manuals to that damned "A" word. :{



Keep up the great R&D Eric. :cool:



Peter
 
Yes they all can do locked down shifts. They do have a controller box.



Look at it this way South Bend Clutch. There will be more smoked clutches with the manuals trying to keep up with a locked auto. :D
 
Strick-9,



Sorry if my question was confusing, I have a DTT 91%. As you know DTT uses the smartcontroller to gain similar features when decelerating, control lockup, etc.



I could have missed it in the long post, but I thougth that is was interesting that the torque converter did all these really cool things, without any mention of a control device.
 
Oops

I did all that typing and forgot about the controller. They are still trying to put the packaging together. I haven't played with it enough to give you much about it, maybe Clint or Don can chime in here and give you all the skinny on the controller.

As best as I can remember it locked up at the dialed in speed, regardless of throttle position, but I am new at this and I barely know when it's shifting! I probably give them fits when they are trying to help me diagnose this by giving them the "huh?" after they ask me to check something;)

Question for s & j: how much hp are you pushing through that transmission? How is it that the input shaft, output shaft and everything else doesn't break with no dampener (i. e. fluid coupling) to soak up the shock of shifting without unlocking the tc? :confused: This means that the plates in the clutch packs are the only thing providing some "give" when the transmission pulls the engine rpm down. How is the transmission supposed to last for more than 1 day even if parts don't break? Those LITTLE TINY clutches are doing everything that the huge one in a manual is when the driver shifts without ever letting off the throttle. How long do you manual transmission types think your clutch would last if you never let off the go pedal to shift, making the clutch pull down the engine rpm at full power every time you shifted? Them little clutches and bands are going to fry big time, eh?! :confused:
 
Stack'd-n-Jack'd,



Nice post, sounds like a nice set up. Did you get a chance to look at any of their turbos?



Bob Wagner, "Does ATS educate their customers?"



Planning on upgrading and becoming an ATS customer? :D

Bob,

You posted another post before i read that one about Black Mountian question. I deleted my post.



Live now? What are you talking about?



:confused: Andrew :confused:
 
I don't see the need to defend my level of mechanical experience, competence, and ATS training to someone whose major line of credibility in these forums rests on the sheer number of posts (over 200) that he has made, that consist of no more content than a few cheerleading words in favor of his favorite product. And those words are often posted in the most irritating manner, in any and all threads pertaining to transmissions.

Anyone in the minority of TDR members that doesn't know me, and that wishes to confirm my competence, can call ATS and ask about me. I wish you wouldn't though, doing so will cut into their time that would be better spent attending to the huge number of customers they get every day.
