LBZ: Lbz work truck

[TheBac]

Like I already said. My truck did it with over 500hp to the wheels with a basically stock trans hauling heavier then him. Never limped.

That is NOT what you stated in your later post below.

Well if you read my previous post on this thread you would know some of these. 1. I don't tow on top tune, I may be a newb to duramax but I'm not an idiot lol. 2. I tow on 90hp tune
3. I never said I tow over 500 to the tires I did say my truck has everything it does now for about a year with stock trans and I use top tune pretty often and if I'm not on that I'm running 120hp tune for every day driving.

You combine 500rw, towing heavy and a TransgoJr/converter, you're going to limp the trans. Not "maybe". Not "5 speed vs 6 speed".

My truck can make over 500hp and has for about a year and I do not baby the truck. Bigger thing here tho is everyone ran the new guy off which isn't cool. In the short time I've been in this little club I've seen it a few times.

Efi live by ppei. I drove it like a truck should be driven, used top tune a lot 180hp And drove it every day on 120hp and towed on 90hp for about a year. She held up nicely. Never shifted weird either.

Well I'd agree with Facebook that's why I don't have one anymore. But this is a forum and a lot of people who are stupid come for answers. But I guess oh well.

One thing you dont understand is that this site is not a "new guy to Duramax" forum, never really was. Pat used to say this was "gradute studies" compared to other forums.
Nor will the members here tolerate BS in any way, especially from newbies. Too many have "been there, done that". Plus, bragging about something that most of us know is not really possible is just asking for it.

Granted, the knowledge base here has dwindled and is nowhere near what it was 5-6 years ago, but it is still ok. Just ok, though.

Now, if that opinion comes off as "rude" to someone, then maybe Diesel Place or Duramax Forum is a better fit for them.....at least until they learn enough about these trucks to hold their own in a technical discussion here.

Look lol In this post I have said my truck males over 5 on tune and has been that way for about a year. I run it often. If I'm not I run 120hp all day every day. I stated that I tow on 90hp. And I never baby it. My trans has basically nothing done until recently and I never had a single issue. Believe it or not I don't care. That's in a nut shell what I said.

5 speeds won't hold what a 6 speed will stock to stock.
I limped my lly lots of times at not near the horsepressure my LBZ was at yet only limped the LBZ it maybe 4 or 5 times.

I never limped my 6 speed, had a converter sudder from hell on 100,120,150 with little effort so I kept it in tune 2 and still fried the c1's, still don't get it, but it's been built for 60k now and I'm sure it'll wear out one day eventually.

Some real talk here. I know from first hand experience what a transmission looks like after years of use and abuse with a stock transmission. I just built a transmission for a good friend of mine who has run his truck for 4+ years with a lift pump and all out 500+hp tune that ran 8.2 in the 1/8 mile (equivalent to about a 12.8 in the 1/4) in a full weight crew cab on 22x10s. It is legitimately over 500 hp to the ground. Anyway, he has been running like this for over 4 years with only a Precision triple disc and a transgo jr. The trans never limped (he does not drive it easy) and the truck did tow from time to time. Never anything super heavy, but usually around 10k lb trailer. The C3s were pretty scorched. C4s were pretty toasty but not completely burnt. C1, C2, and C5 were mint. You could still read the part numbers on the frictions. That's what I know.

From the little bit that I do know yeah 500hp might hold for a while on a stock 6 speed with a transgo and keeping it cool. Stock converter is gonna be toast. Clutches will be toast. But still might run. Add a better converter and yes it'll last even longer. I think it's possible. But rare that someone gets it to hold. As far as the OP if he didn't know whether or not an egr delete was beneficial he probably doesn't know much about these trucks In The first place. But either way this thread is :beatdeadhorse:

There is clearly a reason you put a built trans in it or you would have stayed stock. Your 500hp was never making it to the ground and your trans was dieing. That's just how it is on a stock trans no matter how you cut it. The engine can make it but the trans just can't get it to the ground through all the gears.

Just watch how you word your posts. you posted against what ALOT of us know to be true and don't have much fact to back it, then had to post some much better clarification on what tunes you actually towed on. We don't coddle newbies, we ride on fact and want to see fact if you disagree on a subject. If you can not provide decent facts to hold your claim, you will get chewed on.

Because putting in a new converter makes sense. Just to kill it when stock clutches shed enough.

Glad I have zf6 six speed, no problem with that. Need to probably rebuild 290k before I make a monster. Is there any info on head gasket blowing on lly?

No I put a build kit in it because I wanted more out of the truck with out having to build the motor. I was planning the trans max tunes, then a turbo set up but people.on her advised against the turbo. I was told I am at the point where if I do more I'll probably stuff a rod.through my block. So that's why I did it. The trans was fine. I don't need fact lol I have literally.lived it. I did all of what I have said.

So you built your trans?

Swapping the mouthpiece is supposed to help. It's restrictive and makes them run really hot.

But I have never dyno it before. I just add the shit I've got done to it with tunes and it should be 5-550. I'm not trying to start shit I was only saying my trans has been stock for about a year of a lot of use and never babied. But I get it that you guys don't want people on here being idiots I see that I just feel bad seeing some these new guys getting destroyed.

What kind of lift pump and tunes were you running before you built your trans? I see you said you got EFILive tunes after the trans build.

 

[2008lmmchopper]

So you built your trans?

Ya beginning of the month I had a ppe stage 5 with the better triple lock convertor with bullet stator. Then got my trans tunes done while it was being installed

I have an air dog II 4g 165 with braided 1/2 in vibrant fuel lines, when I deleted it I went with efi by kory Willis with a dsp5 set up. I did trans tunes and updated motor tunes when I built my trans.
