EZ + Injectors with stock auto

[ilplumber]

Hello fellow members,

I was wondering if it is possble to step up the injectors only slightly with the ez already in place with a stock auto trans. I have had absolutely no slippage with the ez even towing heavy trialer at wide open throttle. If I am careful while towing can I also upgrade the injectors a little. Thanks.

I would bet that if you do it you will have transmission problems shortly there after. What I would do is save the $$ and get your transmission done. It is worth it, trust me. When I got mine done the difference was the same as when I put on my EZ. The truck just felt better. Bill K once told me that he had customers that had stock trucks and thought the transmission mods he did were enought bombing because the truck felt that much better.

Bill K says that there is NO WAY a stock transmission will hold it. Some brave souls have done this though, not me though. I have turned up the line pressure some, but still no way i would try it.

U'll B sorry!!

I did an E-Z W/stock transmission and it didn't last long.

If you do it and treat it decent (abuse it along it's strenghts and not it's weaknesses) it can be done for a long time. It will not die as a rule. If you hammer it all the time it will die quickly.

I ran 275 with an ez box. Every clutch pack in the trans was either blue(from the heat of slippage) or welded together. I tried to baby the truck but when towing it is difficult when you are making the power you will get from those mods. Even if you did not slip, the stock torque converter will not be in its efficency range and the truck will seem like it is just making more noise and rpm without gaining momentum in proportion to rpm gain. I would have saved several hundred bucks on my rebiuld if I had just stayed with the ez. Of course I am sure others have had better luck.

Ilplumber,you wont get slippage at WOT,with just an EZ,that is not where the transmission slips you cant drive wide open forever,once you settle into a cruise,and a gentle hill comes up,a stock truck would need 3/4 throttle to pull it,you now need 1/4 throttle due to the injectors/EZ,you now have much less line pressure with much more torque,this will slip it with both injectors,and EZ,Lsmith,by babying the truck(you give it low throttle,which results in low line pressure. This is what slips the transmission. IM,it would be better to drive it with more throttler,and keep the RPM's up high,this style of drivng will keep it at higher RPMS. s,keeping OD off until 2500 RPM'd where it has less torque. I would not combine injectors with a EZ,at all. Towing with both is insane,and a sure way to burn up the transmission,Dont kill the transmission,at the minimum,get a Valve body ,this will keep you from, slipping the clutches,and lockup for a while. I learned with my 96 ram,it had a TST#6 plate,I could roll on and slip the lockup from 1500-1900 easily,but if i just stomped it,it would never slip. ( I had a mystery switch)In fact i could roll on and slip it,then stomp it from there and the tach would drop back down,and the lockup would stop slipping. By the time i addressed this the transmission was in pretty rough shape.

Thanks. The only reason I inquired was that I saw EZ + injectors (stage 1) for sale on wildcat site. They said nothing about transmission upgrades till stage 2. Will I need a torque convertor as well as a valve body? Sounds expensive. .

Ilplumber,

I run an EZ, with bhaf and elbow.

If I add anymore power, I know my stock transmission will go south in a hurry.

If you added injectors and the EZ, I think your transmission would fail within months, no matter how nice you drive your truck!

I drive mine like a madman, and my transmission is going south! (i think the lift pump too!)

I dont like the slushyness of the 47re, and I plan to go with a DTT valve body and converter, and rebuild in the next couple of months.



Then its all down hill from there!!

 

[ilplumber]

So, if I add the VB and TC and some honkin big injectors what is the next thing I will have to replace?

 

[JR2]

Iplumber - do you really want to go there



If you add a TC/VB and some big injectors I would think that next you would need a new turbo. Bellow is a list of what I have on my truck right now. I will say that I do not tow much and when I do I leave the Fueling box off or the EGTs go out of site.



My 2001 has DD3's, a EZ and a PE (together these are a comp), DTT TC/VB, a Piers HX35-12 and a BHAF. I also have upgraded the fuel system and moved the lift pump to the rear. I guess I have something like 400-450 hp. I am going to get a new turbo and just have not decided which one yet (PDR-HX40 or BI bomber or some rumored turbo from DD????)

 

[Snow man]

ilplumber, i feel you could get away with a VB alone if you werent towing,but the towing will quickly kill your transmission with EZ and injectors. I'd call Bill K or another diesel transmission expert to get their opinion on what you need to tow your weight,and use the 275's and ez together.

 

[ilplumber]

When I tow. I only use direct drive. No o/d. Tow anywhere from 6,000 - 11,000 pounds. Is changing the vb simply bolt in deal? Since I do not tow in o/d ever would it be better for my transmission?

 

[LSMITH]

I respectfully disagree. The VB is all you need when towing if you use your head. The only thing that will kill your transmission when not slipping is heat. The stock TC will make some heat for sure, but if you monitor temps and use your head a TC is not necessary at all to tow with major power. The mistake that is most common for people towing is to baby it around, light throttle pressure with added power is many times harder on the transmission than heavy throttle. You do not need a TC to tow with the EZ and 275's. I would do a shift kit or a VB if you are towing often with the EZ and 275's as a safety margin though. The VB is pretty much a bolt in type of mod, but be prepared to make adjustments or have them made. 3 or more pan drops to make adjustments would not be uncommon. MHO, hope it helps.

Now i know how your auto has lasted this long with an EZ ,keeping it out of OD wwhen towing has saved it,if you do not tow in OD you should be ok if you use yor head,but id still get an expert opinion on it. I am by no means an expert,so I d call one to be sure.

You will fry your transmission in a short period of time even with a modified valve body. I just went through the very same thing. I had a modified valve body, pressure lock, and stock TC. Towing I could not slip the converter with just the stage 1 injectors but turn on the edge comp on level 1 (which is the same as the EZ) and I could slip the converter at will unless I was over 65mph in third direct, any speed under that and the converter would slip if I put the throttle down. If you slip the converter long enough you will need a complete rebuild due to contamination of the transmission from material shaved off the converter lockup clutch.



Why spend money on extra HP if you cannot use it, It's nice to think a little more power will make the truck into what you think it should be but if the transmission won't handle the extra power why spend the money.



I just upgraded the whole transmission from BD and the truck I bought three years ago now tows like a dream. I just came home tonight from a weekend trip and towing in OD against a 30 MPH head wind at 70 MPH and I never had to use full throttle once going up hills and is a thrill only someone that has experienced it can know what it feels like. I run the comp in level 1 only (I don't have the pump wire hooked up) and have stage 1 injectors, stock air filter and stock exhaust, a full set of gauges. With this transmission I can now idle up out of the river valley I camp in at 1000rpm's which before took 1800rpm's and sounded like the truck was trying to do more than what it could, all rpm's and not moveing much.



You read alot of threads about people makeing high Hp but most of them don't tow and when they do they don't use all the HP for towing. If a person was to use extreme power for towing there are many things they have to do to keep things from giveing up the ghost. The more one does to up the power the more you have to upgrade other components.



Sorry for the long post but what one expects and reality can sometimes get confused. In my experience a stock TC with a modified valve body will not hold up for long with an EZ and stage 1 injectors, especially towing.
