Best Transmission Mods?

[John]

Dave (Goerend), you are lucky you added that exclusionary remark in the last paragraph of your last post as I was all ready to latch onto your previous statement about climbing the curb.



Even though Bill advised me to go with the DTT 91% TC, I decided to go with their 93% model (after having driven the DTT Ram with that model installed... which BTW, he installed several days before I arrived at DTT so I could demo it as well as the 91% TC in a customers Ram). He even tried talking me out of it again over lunch but I was he!! bent on my choice! Against Bill's recommendation, I became the first customer for their 93% TC, a decision I'm still glad I made today.



Efficiency, I'll give you efficiency... my DTT 93% TC will climb over a curb at idle (I don't need no stinking boost!)

john, i did not start running everyone else down bill started that long ago and he runs my stuff down even thoe he has never tried one. if he has i suspect he will give the name of the person who has one that he has driven. i have no problem with any of his stuff and i have always told anyone that who has asked.



when he starts to call me a lier and says i do stuff behind his back i want the proof. so i am still waiting for his email



if you like a converter that is that tight at idle that is great. some people do not like excessive creep because it reduces the drivability. some people like it some dont.



the point is if he wants to run me down i will show that he does the same things he accuses others of doing. says one thing one day and then something else months down the road.



if you want a dependable trans that works it can be done in most cases for less than 1200 total. any 97 and newer needs very few updates.



bill says he cares so much for his customers how much did your upgrade cost. did you tow your truck there or did you drive it. if you drove it, there could not have been too much wrong so i hope you did not give new or rebuilt price for an entire unit when you could have had dependability for much less.



the last 3 trucks i have done all were less than 1200 and 2 were less than 1000 they got a converter valve body the trans was dissasembled and inspected the seals were replaced and one needed both sun gears all the other updates were already there from the factory. all pull combined weight of over 20,000 lbs and all were happy. all had a badly slipping converter clutch when they came in but when we cut the converter the lining was simply glazed and the cover was burned so there was no metal in the unit. i dont sell you anything you dont need. what you get is what the unit needs to be dependable. and more often than not if it can be driven for several hundred miles to get here there is not much wrong

Contradictions

Dave,



Did you post the wrong two paragraphs above? I don't see any contradictions in those posts.

In this paragraph:

JP IS CORRECT, MOST OF THE TC'S IN THE DRAG RACING INDUSTRY PREFORM ABOVE 94% IN TODAYS MARKETPLACE THAT IS THE EXPECTED NORM. HOWEVER THEY MEASURE AT APPROX. 6000 RPMS PLUS, AND MOST OF THESE DRAG CARS ARE UNDER 3000 LBS.

IF THAT SAME RACER WEIGHED 6000 LBS, AND YOU MEASURED IT AT 6000 RPMS THE CONVERTER WILL NOT HAVE PREFORMED AT THE SAME LEVEL.

THE SAME IS TRUE IF YOU TRY TO MEASURE THIS SAME CONVERTER AT 2000 RPM.

WE USED THE SAME METHOD THE DRAG RACERS USED TO TEST THEIR CONVERTERS, SIMPLY BECAUSE IT IS THE METHOD THAT WAS AVAILABLE TO ME AND I AM FIMILAR WITH IT.

He is saying if you double the weight of the car and everything else is the same, the TC efficiency will be lower.



In this paragraph:

WE USED THE SAME TRUCK, SAME HP, THESE FIGURES HAVE NO MEANING TO ANYONE OTHER THAN DIESEL TRANSMISSION TECHNOLOGY, FIRST ALL OF YOU DO NOT HAVE OUT TRUCK, YOU MAY NOT HAVE OUR GEAR RATIO, YOUR TIRE SIZE MAY BE DIFFERENT, ALL THESE VARIABLES WILL AFFECT THE OUTCOME.



IF I CHANGED MY GEAR RATIO FROM 355 TO A 410, THE TC EFFICIENCY IS GOING TO GO UP SIMPLY BECAUSE THERE IS LESS LOAD ON THE CONVERTER



IF I INCREASE THE AMOUNT OF HP THE EFFICIENCY LEVEL OF THE TC IS GOING TO GO DOWN SIMPLY BECAUSE THERE IS MORE LOAD BEING PLACED ON THE TC BY THE ENGINE.

I don't see the difference. Again, he is saying every little detail will change the TC efficiency. It seems to me, he is saying another truck wouldn't show exactly a 91% efficiency because of the many differences between the trucks. The numbers 89%, 91% and 93% effieciency have no meaning to anyone other than DTT. Those were the numbers their test truck got and they just named the convertor by that percentage instead of an actual name like stock, modified and race convertor.



I'm not trying to pick on you. I've emailed you a few times and you answered some questions for me. I enjoy learning new things. I learn more from the 'heated' posts than I ever will from someone bragging about how good their transmission is.



Thank you for coming back to the board.



-Chris

Just having bought a truck with the BD converter and valve bodie I was wondering how these fare in this converter war. I really like the way it shifts and the shift points ,and want to know what to expect out of this unit? Thanks RJ

Close this tread

Well personally I am ready to see this thread be closed. This is getting old and I dont really believe much of this anymore. I suggest that people go and read the posts and draw thier own conclusions, like Strick-9 did. As I have also gone back and read a few of these and found my own opinion does not match the crap mentioned in here.



For my example, I use the mentioned thread last winter where bill says its normal for a transmission to take 2 minutes to warm up. Exact post was not mentioned, but after searching I offer up:



https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=9647



In here the original question is a specific question whether anybody with a DTT setup has a drainback problem. Then makes reference to a BD valve body, a drain back problem, and the fact the problem takes an eternity now that its cold.



Bill says:

Eternity is a very long time, now if we are talking about a minute or so this is relatively normal for most aftermarket valve bodies or shift kits.



The reason why it is more pronounced after the install of the valve body or shift kit is because of the lube charge circut that has been drilled. Depending on the drill size used in the lube circut the drainback can vary.

[snip]



Now saying that a long warmup can be associated with over drilling the valve body, is not the same as saying its normal for all trannys to have a long warmup. Which is now I read this post.



In the end, that is also a long post with lots of crap and when I strip away the crap and finger pointing, I dont see a lot of disagreement about the original problem.



No one disputes Bills suggestion of the probem. Bill says he would not do anything about this problem. As he always allows his truck to run a short time before driving off. Dave says that anything longer that 8 seconds is a problem and should be fixed. Again my interpretation is Bill does not say its not a problem, just he would not do anything about it, if it were his truck. Dave gives lots of examples of many trucks that charge right up, even in the cold. To me only proves that none of those valve bodies were screwed up. Finally at the end of the post Dave eludes to low fluid problems related to old Chevy thm350 trannys. -- The majority of that thread is about tc drainback, and no one gets right to a low fluid problem. No one says its normal for all transmissions, no one says its not really a problem. They, in my opinion, only disagree on whether they would fix the problem and why they choose that position.



So I suggest you draw your own conclusions. Dont use mine or Daves or Bills, etc.
