Engine/Transmission (1998.5 - 2002) Torque Converters

[BLACKRAM]

Using a Dr. Perf Phase II. Who has the best TC/vb? Anybody use DTT or Pro-Loc? Anybody use one of them and then switch because of problems?

Got a Bill K. converter and VB on its way as we speak. I think the products he sells are the best on the market for the time being.

He is a very knowledgable individual who does this because he enjoys it. I am a former Allison auto quality and reliability trans tester, and the product I purchased from Bill is a field tested, reliability proven piece of quality work. I am a very picky person, and you can bet that if I am not satisfied with the converter and VB, this website will be the 2nd to know a bout it, with Bill being the 1st.

I have yet to hear anyone complain one bit about his work or products, and he is very helpful as well. Give him a call, you wont regret it.

i have the DTT TC and VB and have driven the a pro torque , and a suncoast . the suncoast drive was before i bought my ram so i can't really compare them , but to me the DTT is better than the pro torque , the DTT has a lower rpm drop when the TC locks , that means its closer to the magic NO EFFICENCY LOSS when in fluid coupling ... to know what the difference drive your stock ram around town with OD turned off , get up to speed that convertor locks , note rpm drop ... now driving along let up on the throttle till the convertor unlocks , and then get back on it to get the convertor to lock ... that harsh feeling doesn't happen with the DTT unit .

I'm intersted to see what members have to say here. I'm in the market for one at the moment too.

Anybody have a Dunrite?

I had the DTT TC&VB installed a couple weeks ago,you will not understand how much more power gets to the ground unless you drive a truck with this setup.
The tranmission shifts are very positive,you feel the truck pull you foward on each shift. I cant say enough about the DTT setup. One things for sure,the full potential of all the power enhancers will never be felt without a good valve body/torque converter setup.

I had the Suncoast, trans-go etc on my 99, you will have to bomb to get the advantage. My 99 was still a rather large dog but the trans worked alot better.

2000ney:

I have a "Pro-Torque" TC and "BD"
Valve Body in my truck and feel
they are good products. I can tell
you this,... . they are ALOT better
than the stock units! I can't say
if they are "the best" or not as
I have not had any other brands.
I have about 16,000 miles on the
"new parts" with no problems noted.
The transmission shifts real smooth.

One area I would caution you on is
the "stall speed" of some converters.
Myself and "Koa Man" both had a "flat
spot" or "lag" right off the line
before we added our 370 injectors.
My stall speed was 1600 and "Koa Man"
has a 1400 stall speed. Your 24 Valve
may not experience this but I wanted
you to be aware of it. By the way,
"Koa Man" has a "Dunrite" Converter
and I believe he is happy with it.
His truck is heavy and he tows ALOT
in his business. You may want to e-mail
him.

Good Luck!

Curiouser and Curiouser... . My stock AT has a stall speed of 1900 RPM. . needless to say, this thing is a pig 'till it locks up. What kind of stall speed do you guys have with stock, and modified ? This will be a moot point for me after next weekend, I'' be putting in a DTT VB/TC... still curious... ...

Have you ever noticed that the guys with DTT products talk about power gains, quick excelleration out of the whole, they don't seem to even consider lock up an issue as they can barely tell when the tc goes in and out of lock up? Do you ever wonder what they are talking about?

Have you noticed that guys with other brands of after market tc's discuss what a dog they are out of the hole? How the stall speeds are too low? How their trucks take off like a rocket when it goes into lock up?
How they can really tell when the trucks go into lock up as it feels more solid in lock up. Do you wonder why?

In your own personal truck have you noticed how the truck feels when it goes into lock up? Does it feel like a rocket and like it launches when it hits lockup?

Imagine that feeling the moment you put the truck into gear and step on the throttle. That is how the tc should feel all the time with proper torque multiplication and proper fluid coupling not just when it goes into lock up.

The reason we do not mill the the oem stator as our competitors do to achieve low stall is because we know it takes away torque multiplication and fluid coupling.

This milling process others so commonly use makes your Dodge feel like a dog out of the hole.

By increasing torque multiplication we have a tighter converter that gives you better power transfer right out of the hole all.

Walter, i do beg to differ with you, automatics are not dogs. I suggest you have never had the opportunity to drive a properly set up and tuned automatic.
I think Walter that you were also the victim as are many out there of the cheap milled stator tc's sold to unsuspecting Dodge owners.

Why else would you be so bitter towards automatics and have sold your truck for a stick?

I have re-read a lot of your posts and feel compelled to comment on it. What concens me most is that eventhough you changed to a standard you still recommend your automatic products you had so little faith in and were so obviouly unhappy with .

Thanks for all of the input. Anybody with a DTT TC/vb in SW Ohio or Northern KY?

Bill I think I said my 99 was a dog, I wasn't blameing the auto for the measley 215HP, although the auto robbed its share of what was too little to go around. I got the ETH/DEE combo and find it superior for my needs. I don't see why a person could not or should not enjoy their autos. I think I said if you don't put alot of miles or tow heavy loads the auto should be fine. I don't hate everybodys auto, just mine. Like I have said before Bill I have had nothing but problems with the autos I have owned, not just DC but GM as well. I have 4,600 miles on my new truck and am loving the stick and extra power. It is a combination of things that make my HO a happier towing platform. I have never towed with a Bombed auto and even if it had the same torque and HP of my new truck it would be slower towing. The gap between 3rd and O/D was too wide for my needs. Dosen't it take more ponies to run the autos than the sticks to get the same amount of grunt? With the new truck I can really feel the power to the wheels. Are you saying that everything being equal(HP and torque) the auto would pull large loads around like the 6 speed? It seems I can keep the engine in a happy rpm range without looseing speed and pulling power. The other thing I like is I don't have have to spend hard earned capital to do the job I need my truck to do, it came from DC ready and willing and under factory warranty(however weak that may be). #ad

Smile Bill and keep up the good work.

When I ordered my #5 plate from TST a year ago, they told me I needed to beef up the trans and recommended a "low stall" TC and valve body. So I bought it. I was new to modifying the Dodge CTD and did not fully understand stall speeds, etc. If I knew then what I know now, I would have bought a TC from someone who would tailor it to the hp level and useage that I need. The TC did make the truck have a 3 sec lag at take off like John P said. I had to up the power of the engine by installing the 370 injectors to overcome the extremely tight converter. I don't regret installing the 370s, in fact I love the huge power increase and now the truck takes off instantly, NO LAG. The TC has shown no signs of slippage and I will not spend the money to change it until it does. I'm sure there are better products out there now and I'm sure Dunrite has made improvements in their products too. That is just the natural evolution of products, like cars, trucks, cameras, computers and what have you.

Bill K, my TC does have a strong surge when it goes into lockup and yes I would like to have that feeling from the get-go. Hopefully my friend who has your VB and is saving up for your TC will get it soon so I can try it out. I still would wait till the TC I have starts to slip though.

Can somebody direct me to a discussion of the finer points of aftermarket autos--specifically stall speed and "tight" converters. What does 89% or 91% mean?



I'll be ordering a TC for Dad soon enough, and don't want BK to have to explain EVERYTHING



Surely somebody 'round here know something.

 

[Devildog]

My DTT auto is holding up great and takes alot of "hot roding" around. I'm in the process of adding more POWER... . Thanks Bill K.

This is a little off the subject but thought you could answer a question for me. In your opinion is a modified 47RE as strong as a stock 48RE. I don't know what the differences are between the two other than an increase in the tow rating, figured you might know. Also, how hard would it be to upgrade to the 48 from a 47, (or would it be better to just modify the 47)?



Thanks

Another old thread ! Bill's words about torque multiplication and fluid coupling kinda remind me of the last back-to-back comparision I had, a few weeks ago. During three days at our shop, I was brought two individual trucks for engine work. The one on the first day was DTT equipped, one that I had rebuilt completely a month before. (transmission was fine, and received it's first fluid change that day, also) The one on the third day was equipped with a recently popular brand of TC & VB. No discussion of trannies with the customer, just engine repair. I drove it after the work was done, to check for driveability, oil leaks, etc. Couldn't wait to get back to the shop, it was a night & day difference from the DTT I drove on the first day. Driving is believing, and in believing, you're gonna want the DTT every time! .

Wade, the percentages are a measure/rating of the fluid coupling efficiency as tested and developed by Bill. Run a search on Strick-9, he had a recent post on what you're asking about. Simply put, it's input shaft speed divided by engine RPM. Go look in the Products forum, the post is in there.

Just a TC? As a transmission builder, I'm amazed at the current mentality that seems to prevail on the boards, that it's okay to slap in "just a TC and VB" and be on your way. Kind of like putting a fingertip bandaid on a 20-inch long sword cut.

Too many other areas of the transmission that need to be carefully addressed, even with stock or near-stock power levels.

The general idea is not to end up having to remove the transmission again anytime soon, which brings additional expenses.

Thanks Briar, I have always questioned this myself. Never really understood the partial investment. I think its about the $green$ stuff! Would rather be safe than sorry so I'll put in a TC and/or a VB, How much did you say for a complete transmission!!!!



If ya gonna get it, get it all!

Wow this is an old thread. wlowe, I wouldnt hold my breath waiting fro Bill K to respond to this thread,since he is no longer posting here. You can go to his forum on his site,and you have a better chance of getting it answered. http://www.dieseltrans.com/

 

[Briar Hopper]

wlowe, Snow Man is right, the DTT forums are a wealth of great technical information, a great learning opportunity for those that want to learn, and a chance to ask questions.

 

[wlowe]

My mistake, didn't realize how old this thread was. Thanks for the heads up Snow Man and Briar, I'll repost on the DTT site.
