im wanting to either run the edge EZ or the quad XZT. i have a basically stock 02 with 116k and the tranny feels good. i probally wont do any other mods besides a chip, will my stock trans hold up to them?

 

You should be OK.

 

what about an upgraded VB?

 

With that many miles, any fueling upgrade may be the straw that broke the camels back.

Throwing a VB or TC at it many not be the right choice either. If you have marginal sealing internally, higher line pressures routinely will kill a trans in short order.

I just built one that had less of a fueling upgrade and less miles then you. Trans was perfect before he was sold "completely safe and easy on your VP RV275s".

Any added power can result in a negative reaction.

fishin2deep4u im confused on what youre trying to say

 

I think he was saying that he just built/fixed up a trans for a guy that had less miles and less extra added fueling then you would with either of those two chips.
The guy added RV 275's (stage 1 injectors) cause he was sold by being told they were "completely safe and easy on your" truck. Then he broke is truck from the injectors.

Thats what I gather from Fishin2deep anyway.

It can be true. I ran the EZ from 45k-67k miles and never had a problem myself. But it is possible for the trans to kick it from even the little added power. Hard to say. Someone else will chime in im sure.

 

Yep.

I lost my trans at around 30K with only an EZ.

It just depends on how the trans was built.

The good news is I get to refresh a 700+ HP holding trans next week.

I Doubt that this is true once the power bug bites look out

My converter would not hold with an edge EZ and RV 275s.

Called DG he only suggested the triple disk TC and told me not spend my $ on the VB

I tow heavy daily and so far so good and that was over a 1 1/2 years ago and 100,000 miles

Also look at my sig it is far and beyond an ez with 275s

Good Luck

 

I dont do much towing at all. i just want to put on the EZ for the milage and extra power. i know a guy who could rebuild my trans with new springs, seals and clutches for 500$ if i drop it out and bring it to him. it that the best route or should i try to get the VB and TQ all with the rebuild?

 

Well I have read this many times before, I have also read that if your seals can handle reverse then they can handle a built valvebody. Reverse line pressures are near 200psi and built valvebody pressures are only 150-175psi. At least that's what I've read. Feel free to correct me if I'm wrong.

 

How hard you push the skinny pedal will also play a major role.

 

I have a stock trans in mine with a tapped VP comp box & smarty, comp on 4x3 smarty on 2 and tranny is running good i got 147xxx miles. I am getting a tranny built this winter. So theres good stock trannys & bad ones.

 

so if i dont romp on my truck 24/7 the stock trans should hold up to the EZ right?

 

yup it should ... but theres always a but

 

I understand what you are saying, however, to get reverse, fluid travels on a specific path, not through every sealing surface at that pressure.


So, it's not possible to draw that conclusion. In other words, when we get a roasted trans, the reverse band and associated parts are almost always good. It has to do with apply time and type of use coupled with the size of the sealing surfaces.

A great example of this is when I used to build commercial aircraft evacuation slides for BFGoodrich AES.

An evacuation slide only needs 3 psi to maintain it's shape and support a couple hundred people. If the tube diameters were smaller, it would take far more pressure to do the same job.

The same thing happens inside the transmission. Pressure is pressure, but a given pressure will act with more force on a larger surface than a smaller one. Some of the surfaces are much larger than what you are speaking of and any approach to those pressures will destroy the internals of certain parts.

Just going back to my example above, an aspirator was a deadly object with only 2 psi on it. We had to use a multi bolt flange and a huge locking ring to keep it from flying apart. I have seen one let go and nearly kill a guy. He was about 50 feet away.

Put that same 2-3psi on something say the size of a golf ball with the same mass and it'll go an inch of so.

This is why the lockup clutch does not need the pressure of another portion of the trans. The apply area is far greater than the relatively smallish servos in the trans.
