20,000 Miles+. If you look carefully at the Hub it"s still black form the coating,Some over spray got on the Rotor and that what see in the Holes,I guess I could have clean them, But I think most Members and guests will pick up on the point.

I am lost here on this one. A convertor will give you better coupling which would help MPG, but if the clutches slip bad enough with a stock VB that your loosing MPG, then your transmission would be toast very soon. I don't think we want to mislead someone on a better mileage claim on just a VB.

well i'll put it like this, i can prove it. !! the vb is the brain of the whole transmission. it controlls when you shift, how hard you shift and how much pressure holds the 1-4 gear packs, and it controlls the pressure that holds the convertor as well, with that said the vb, under stock to mild hp will bennifit the user very well, he will save money,by not byeing a convertor, save on fuel--the vb now allows for quicker, more positive shifts, and cooler temps--the vb allows for constant fluid flow, so in other words you are making the stock transmission components last the longest, under the cheapest dime... .....

p. s. i did say stock to mild hp, anything more than 350hp or so and you will need a convertor. so back to the origonal question, a vb will help immensly on a stock truck that is towing heavy. hope this helps ross Oo.

Actually the ECM is the brains of the transmission. You can change the shifting time and you can swing the shift points either earlier or later by changing the throttle pressure/governor pressure relationship. It would be interesting to see the proof that a VB increases mileage, and by how much. A quicker shift can't give a measureable MPG improvement. I agree that it is a worth while modification, but not for fuel economy. It will help the clutches, the convertor lockup clutches, and allow the user to hold more power. But if your clutches are slipping, you won't last very long with slipping transmission at any rate. I agree that it is a worthwhile improvement for transmission life, but I can't see it giving over a measurable mpg improvement. I have been wrong before though. Just ask my wife, well don't ask her I keep telling her she married Mr. Always Right. :-laf

How about showing a front rotor? I wouldn't expect the rears to show much stress at all since the fronts do 80% of the work. Are you seriously disputing my post? Do you seriously find customers out there who buy into this? I guess there is a sucker born everyday :-laf

Diesel Power:



I have had experience with aftermarket trannies; all good. I have modified a 2002 bombed with Stage IV injectors, TST powermax, and hx40 turbo. The transmission was upgraded to a 91% billet converter and valve body from DTT, all with good results. I am sure your trannies are just as good if not better (not trying to start a transmission war)...



Anyway, my objective is to refrain from bombing and avoid transmission expenses if possible. If and when the stock auto takes a crap, then I would consider upgrading to an aftermarket unit, but I would prefer not to spend the money at first.



So, my question for everyone is, how will the stock unit perform, and how long will it last.



I am also considering waiting for the Aisin to come out in January, but there's NO information about it...

The Aisin will be out before Jan. I have the VIN # on my cab and chassis right now. I should have delivery within a month to six weeks. I'm a hotshot driver and regularly tow the weights you are talking about. If you can hold out for a little longer, I'll be able to give a report on how the Aisin works pulling a heavy trailer.

Here it Is

Fine... . do I really have to go home and take pics of the holy rotors I have that are full of stress fractures? It happens, it is a well known fact. I dunno, maybe you don't use the brakes much



I'm not going to argue with you anymore Todd... :-{}



Sorry for the hi-jack

 

[TCDiesel]

BHolm, I do not disagree with You, In some applications the Drill Rotors have prove faulty, But when pulling heavy they Perform well (With Slots), I have had Both from the most expensive Powerslots to Ebay specials,I was tried of the spongy peddle and vibrations associate with solids. . Your opinion and knowledge are respected around Here . Todd

Let us know, along with everything else... MPG , handling, you know the drill !!!! :-laf

I read most of the replys on here I skipped the children that can't play nice. The conclusion I've gotten from this is buy a 6 speed or shovel some $$$ on a upgraded auto in your new truck.



Good luck

Good summary

You will likely not enjoy the way the stock transmission performs, although it may last a good long while. I get tired of shifting gears and wanted an auto for the wife as well. Hated the stock transmission mushiness, and $2500 later it is a dream to drive. Good luck with your choice.

I tow pretty heavy and run hard when I do. With the TST power I slipped the converter. So I bought a triple disck and a VB. The shift to overdrive was terribly agressive and a few weeks ago broke the input shaft. I now have a billet input and laminated flexplate. The converter was repaired and I can't tell you how the truck is doing because the converter goes into lockup and won't disengage. Either a problem with input or converter or VB. Will hopefully get it taken car of soon. Be aware of Valvebodies that shift too hard into overdrive I am sure this is what broke the input. If you get a good converter go ahead and get the input shaft and flexplate why you are in it. i skimped and am now waiting on the repair.
