2004 LB7 Duramax 3500 Dually Sat For Four Years!!! Will It Run?!?!

- We purchased a 2004 LB7 Duramax crew cab long box 2wd dually! It sat in a farmers field from 2017 to 2021 and was sunk into the mud! The mice got into the fuse box and wire harness, meriting some electrical repairs. Watch as we get this rig started after years of sitting!

How can they say 2 wheel drive dually an it has 4 wheels on the back don’t that make it a 4wheel drive lol
😂 not wrong!
4x2 instead of 2x4
I think it has six speed????¿!!!!!¡....
No budy the front tires are not moving
@@justusone1 it’s a joke
Bought an 07 Classic 3500 2WD
Service truck with an AutoCrane, 356K for $5,800. Now at 490K 2 years later and the damn thing just works... What a truck!
Dang! That’s awesome!!
So far I’ve never seen anyone hate a gmt800 truck because of mechanical issues they are extremely reliable and they are amazing trucks I own an 04 2500 and I love it take care of it it it’ll serve you well for many years to come!
That’s awesome! I know a lot of people that like them, it’s my time to jump on that train!
I have an 02 2500 LB7 2500 and a 06 3500 LBZ dually and love them both
I will say they are good engines and transmission. The body is just junk. GM needs to go out of business. They manufacture p.o.s Government Motor!
@@edwardloose9668 I wouldn’t say that at all. I had a 99 (1500), 05 (1500), 08 (1500), 16 (2500) they all were great trucks. The 99/16 was the best, were all abused and other than the 08 : all made it to 200k miles. They all were sold running. My dad had an 05 2500HD that took more abuse than any truck I’ve ever seen. Yes, I’ve switched to Ford since. Since 19, the GM products seem to be SubPar compared to the competition. Pre-19 I would say they were overall great trucks : even the 1500s.
@@edwardloose9668 did you mean dodge, and their tortilla chip plastics? mine has 370k miles and is solid, no rattles or rust
That Duramax will really come to life with a tune. Congrats on a great find.
Thanks!! I would like to wake it up, although there is something to be said about an all stock cat-eye with only 140K miles...
@@MickelsonRacingChannel A good tune will make it very stout without hurting anything. Stock LB7 is in the 250-300HP / 500ft lbs area. You can add 100HP+ and 200 ft/lb+ with tune. Depending on the tuner selectable power levels so only when you need it you get the extra. Exhaust, some like CAI but I see conflicting info on how good they are in reality. They usually sound better though. haha A lift pump for sure, help preserve the CP3. Alot you can do with that engine for sure. Great find!
@@donaldwilliams6821 that extra power would make all the difference in the world to me! That is my biggest gripe about the Duramax, compared to my tuned 6.7 Ford.
@@MickelsonRacingChannel There are SO many upgrades available for the LB7 from mild to wild. CP3, fuel filter o-rings, water pumps are some weak points. I did a quick search and this page has a pretty good summary of known issues. dieselresource.com/diesel-resources/6-6l-lb7-duramax-problems/ If you make really big power the older Allison's aren't up to the task in stock form. Another reason i like tuners with settable power levels. Enjoy! Post updates please if you decide to mod it at all
@@donaldwilliams6821 will do! I’ll check out that page for sure, who knows what I’ll do with it!
I fell in love with my 02 2500hd, SRW first time I test drove it. Sold it recently tho 😔. When the LB7 fires right up and purrs at idle, not much else can put a smile on your face that quickly. VERY little modification will get that engine to wake up. It has no emissions devices except a cat I believe. Cold air intake, intake heater delete, turbo pressure adder valve ($15 adds 8 pound boost), and possibly open up the exhaust and you're now at 350hp/600 lb ft so ez. Personally I'd sell the dually for a SRW 4x4. Duallys can't park anywhere. Not practical but I bet the dually can pull 25k lbs on the highway like butter. Fun video, brought back memories! Thanks 👍
Glad you enjoyed it! Sounds like those are some great and cost effective mods!
I’m a Chevy guy you can’t beat the 2000,s model seats they set so good . Was picking at my daughter about selling my z71 an she’s like no daddy the inside is so comfy
The seats are good!
Greetings from Cleveland, OH... Home of PB Blaster... Drive it like you stole it because you did knowing that it only needed two batteries and a tweaking of the wires to get it running right... Know that Zeus enjoys it and you've now have a decent tow rig for your trailers and other needed uses....
Heck yeah! It’ll serve as a great tow pig!
all 1 ton gms of that era were 3500s. 1500, 1500hd, 2500, 2500hd, 3500.
1500- typical half ton
1500hd- chevy wanted the toughest half ton, so they put a 1500hd badge on a 2500 to sell it as a half ton. semi float rear end, 6.0 and 4l80e
2500- same as a 1500hd
2500hd- full float 14 bolt, big brakes, big cooling, larger frame, 8.1 option and duramax option
3500-dually
after 08 or 09 when the general did the gmt900, all 3/4 ton and 1 tons were "HD"
That’s awesome information, thanks for sharing all of that!
Finally someone got the 1500HD and 2500 right😂
These years of Duramax’s is solid engines!
They’re pretty good!
Funny I have a 11 powerstroke and a 03 lb7 I love my lb7 and it’s way more comfortable. Nice new truck!
Dang! That’s funny! Which pickup do you prefer, which do you like better? I like the LB7 quite a lot, but the 6.7 powerstroke just makes so much more power.
" Get right inside the box with really minimal effort "
Giggity
Excellent find August!!
Thanks Bill! I’m pumped!
@@MickelsonRacingChannel I would be too if I had that!
Awesome deal
Congrats 🥳
Thanks! I’m pretty stoked!
Should be a LLY being a '04, with the 5-speed Allison 1000, 6 speed came out in 06, Also should have a g80 rear end with 4.10 gears and posi
That’s good information! As I understand it, 2004 was a changeover year with 2004.5 going to the LLY. This rig was an early 04 and did have the LB7.
WHAT AN AWESOME FIND!
Thanks Captain R!

Yeah, it’s not bad!
Hey man, liked the video but would have liked to have seen some more outside the cab footage and drive bys/exhaust sounds overall really cool, glad to see you getting this one working again and on the road
Thanks for the feedback Kal! I’ll make a note to include more of that ok the future videos!
Yeah man I’m gunna subscribe! Hope to see some more videos on the old girl. Just saw your race week videos I’ll give those a watch too.
@@kalh.9241 that’a awesome, thanks Kal! Glad you enjoyed it!
Wow that truck is amazing
Thanks!
I just got a 02 with 300,000 miles on it for 3k like this, It's running fine. 👍
That’s awesome!!
That's a big girl and she fired right up
Instantly! Unbelievable!
great find
It sure was!
Very cool. I'd be interested to hear how much you paid for it????
This LB7 Duramax gear is 5th gear. It's a 5 speed Allison Automatic.
Awesome, thank you! I was curious!!!
Also as long as you don’t go In a bunch of mud and snow a 2 wheel drive should get you all the places you’d want to go
That’s my theory! I think it’ll work out pretty well!
I have 2004 Chevy 3500 crewcab 4x4 gas 8.1 Allison Tranny 262,000 miles love it. And I got 2001 Chevy 2500HD Extended cab 4x4 Duramax LB7 tow tuner and K&N cold air breather and only 92,000 miles and a 1999 Chevy 2500 excab 4x4 6.0 gas 212,000 miles.
That’s awesome!!!
On the first try?? Wow!!!
Seriously! I couldn’t believe it!!!
that thing just sprang to life!
great find
@@That1Modmenureviewer surprised the heck out of me!
@@MickelsonRacingChannel runs great though. can you do a burn out in it?
@@That1Modmenureviewer I never did try that.
@@MickelsonRacingChannel aw. i got an idea though! try and get an lbz!!
@@That1Modmenureviewer I do want to get an LBZ actually!
Of it’s an o4 it’s a lly. And the 3m rubber wheel will remove the vinyl decals with out removing the paint. The lly trans is a 5 speed.
Good info! This rig is an LB7 though.
@@MickelsonRacingChannel It is an LB7. The Allison was a 5 speed until you hit the LBZ in '06.
04 is not an LLY, 04.5-05 are LLY.
Nice looking truck. Besides the Duramax diesel engine, you have the highly-desirable crew cab. Does the truck have the Allison automatic transmission?
Yes, it has the Allison as well!
I see a bunch of people try to start things that have been sitting but they never change the fluids first, what kind of problems could there be from that?
You could run into issues with foreign objects or water in the fluids. Dry bearings, etc. People also don’t want to drop hundreds of dollars on fluids if it doesn’t start. Most of these folks will make sure it runs, then change all the fluids immediately after.
nice truck
Thanks!
The trailer wires might be mest up on the stop lights
There's 5 gears but when it goes out you can do the upgrade to the 6 speed with the rebuild
Sweet! That’s awesome info, thanks!!
What is the failure rate on the 5 speed in stock form? Stout or no?
@@MickelsonRacingChannelwith stock engine lasts long time.if modified over 75 hp and 200 ft lb. Will start slipping convertor.
@@techs1smh13 good to know, thanks!
Awsome.
Thanks J.D.!
Check the maga fuse by the battery two bolts
🔥🔥🔥🔥🔥🔥
Congrats body. 👏 🇺🇸🇵🇷💯🤝👊
Thanks!
well getting an 01 LB7 started after replacing the injector cups and also the hold down bolts that managed to snap somehow isn't that easy lol but yea a Duramax is easy
Must have taken a while to get that fuel primed!
Volts want go up until it’s started up because the alternator ain’t charging when it’s not running lol
Good point!
Should still have 12 volts
Pretty sure the "HD" fleet is gassers. For example a 03 2500HD is a gassed and just a regular 2500 is a duramax, I could be wrong
Interesting, that could make sense!
I have a 02 2500hd lb7
@@DMAXmarty I also have a 02 2500hd, it’s a lb7
The hd is just a higher gvw rating on the 3500 the 2500 got bigger brakes and a couple other things and a higher gvw the 1500 got I believe a 3/4 ton axle but still 6 lug and got the 6.0 instead of the 5.3 or 4.8
Good info!
DURAMAX OLE SON!!! You will not beat an Allison transmission they are bomb proof!
Awesome to hear! I hope it lasts for a long time!
I.. believe most R just 5 speeds .. but some can bee als0 just 4 - sppeds to0..i 🤔 thi k bro.. just enjoy it.. i even like the one u got... just promise me u will put good oil & transmission fluid into it..
Thanks for the info!!
Have you done anymore work on the dually August?
Got everything working! Borrowed a tool from Mortske and managed to remove all the decals. Spick and span now! We also pulled the big trailer 360 miles round trip last weekend! She’s a real workhorse!!!
@@MickelsonRacingChannel maybe show us the truck briefly in one of your up coming videos so we can see the difference. Did you run the Impala at the strip last weekend?
@@Bill-xc8le definitely! Videos are about three weeks behind my life, it I’ll definitely show the improvements! We ran the Impala last weekend, that video will be out in two weeks!
18:00 shut it off drain and flush the fuel change the filter!
That’s a good call!
Duramax is a strong pulling machine and it will pass everything on the road except a diesel station.
I wish I felt the same way about this one! I felt this rig just didn’t have the power it should have. It really struggled to pull my 48’ 15,000lbs trailer.
My 2001 2500HD LB7 gets 22-23 mpg highway and 15-16 city . Love it. Tow tuner and K&N cold air breather and only 92,000 miles.
I have a 2004 Allison in a 3500 8.1 gas it is a 5 speed.
@@MickelsonRacingChannel Well, it's rated output is what it is for that year. You are asking a lot of that truck pulling a 15k trailer and at that length. Obviously newer diesel trucks tow better because they are 20 years newer with more power and better technology in parts.
@@2015_Rubicnn the newer technology certainly does perform better!
The Transmission selector lights are our because that truck is telling you to convert it to a ZF6.
SIDE NOTE: Get a Fuel pressure regulator in that, the tach is bouncing, your fuel is surging. PEACE BE WITH YOU!
That is the best tip I've heard yet!!! No wonder it doesn't feel like it has all the power!
Lb7!!!
Heck yeah!
that’s an LB7 for ya they run forever
They sure seem to!
Nice find but what did it cost you, that to me would see if it's a good find.
I’m not sure I want to disclose that! 😬
@@MickelsonRacingChannel OK, NO PROBLEM, IT'S JUST THAT I SEE ALOT OF PEOPLE GET THESE SO CALLED GREAT FINDS BUT DON'T SAY WHAT THEY GOT THEM FOR. LIKE FOR ME I PICKED UP A STRAIGHT CREWCAB 1997 3500 4X4 DIESEL WITH 156,000 MILES SAT FOR 3 YEARS ONLY HAD STARTER PROBLEM FOR 1,200 HERE IN ARIZONA. YOU STILL HAVE A NICE FIND.👍🍻
@@stevenlukowski562 Nice find!!!! I’m not far off from that…
@@MickelsonRacingChannel COOL.👍
Bow tie for life
I am a fan of the bow tie!
Didn't those transmission came with 10 speeds
Not in 2004
He’s probably smelling all those mice that made their home in that thing.
He definitely is…
Don't forget to pump the pedal for starting. 2 taps should give it enough fuel for starting.
Seemed to go pretty well!
Dang
Thanks for stopping by to check out the channel!
My 2002 lb7 dually has 373 rear gears
That’s pretty good!
The Allison 1000 has 5 gears abd you probably have the 3.73 gear ratio if not the 4.10
Awesome, thanks!
@@MickelsonRacingChannel I didn't realize that this was an older video.
@@hilham89 all information is good to know!
Loves hearing his own voice I guess…
Thanks for the feedback!
Do not tune the truck unless its followed with a option for the 4-5 and 5-4 shift safty.
Interesting, I have not heard that before. What does that benefit?
@@MickelsonRacingChannel the weakest part of the Allison 1000 is the 4 to 5 up shift and the 5 to 4 downshift. Not sure exactly why but its is highly known in the lb7 group to have a tune that defuels during those shifts. Most tuners already know and add it anyways. If you do tuns it efilive with a position switch isnthe safest and most capable tuning you can get. Will keep dependability and add performance.
@@kylenphillips3821 that’s great info! I’m new to the Duramax world, so it’s really nice to know this stuff! Thanks!!
@@MickelsonRacingChannel yes sir no problem. If you have facebook im.in a group for nothing but lb7s and it has some gurus that could help answer questions you got
HD=heavy duty?
Good point!
Why was it parked
It was parked because the farmer didn’t trust it anymore and bought a new pickup.
Two Wheel Drive is better. I bet. Less Drive Train to worry about. Of course it isn’t a train… typical general motor lighting. One can replace the headlight switch.
I prefer 2wd for that reason.
It,s not a6 speed untile 2006 ,,when u drop the shifter all the way down It should tell u how many gears it has
Good to know, thanks!
U KNOW THE 2O22 DURAMAX TRUCKS HAS 10 SPEED TRANS
@@justusone1 yes, pretty neat!
I love stepsides really wish they still offered them
💯💯💯💯💯💪
Why did the farmer park it? Its got to have issues to expensive he didn’t see the value to repair it.
He parked it for the mouse eaten wiring harness, which I repaired.
@@MickelsonRacingChannel very cool 😎.
The PRNDL display is probably just dead as that generation of GM dash clusters are terrible. There are dozens of companies that specialize in rebuilding them. I had to have my 2004 Suburban cluster rebuilt.
I’ll have to check that out!
Have an 03 hd 2500 in SOCAL. Called the gauge guy came to house removed and desoldered all the stepper motors and install new motors tested it before installing 280.00. done
You should convert it to 4wd
That would be sweet
So has it set for 4years or a year you said the tires didn’t have weather crack after setting in the sun for a year but you said been setting 4years
The tags are 2017, so it’s been sitting for four years to our knowledge. Good catch though, I did say that!
@@MickelsonRacingChannel sure surprised me when it started right up why was it parked
@@southernslipping4225 it surprised me too! I didn’t think it would fire up at all! It was parked due to mice chewing up the wire harness.
Lb7 has a 5 speed trans, not 6
Awesome, thanks!
5 gears in trans
Ta know cover ? Stop lights ? Man I would say that’s Dakota language but Mortske doesn’t talk all weird lol just bustin your balls bud nice truck !
Ha! Us Nort Dakoda’s are a bit different!
😎🤔👍
Pretty sure they used a 12 speed in 2004
Bitchin
GM was really ahead of their time...
It ain’t much but it’s honest work
They don’t make em like they used to
That’s a fact
See zip ties n bias plies cold start slave lake and all the other rusty old Fords he revives. That's some impressive stuff haha. You got lucky it's probably got blown head gaskets though. I didn't notice how old this video is. Might not matter now.
It was a good unit! Put a few thousand miles on it pulling my big trailer. It’s sold by now though. Zip ties and bias plies does a good job! As does Mortske!
5 speed
Awesome, thanks!
5
Thanks!
Why would u call it junk u bought it as it was take the bad with the good im sure u pay very cheap for it ,sell ne tgd bed lol
Absolutely, take the good with the bad!
Ck fuses
Good call!
SMH...all this stalling around knowing the truck would start.
Thanks for your feedback!
Hard to beat a Chevy😅
Tis true
I’m mechanic for GM for 40 years that was a halfway decent Duramax but all of them really and truly junk they do not last long I hope that one does good for you
Good to know that they are all junk!
Speak for yourself. Ive been turning wrenches also for that long and if you take care of them, they will take care of you. My 2012 LML 2500HD has 265k and I couldnt be more pleased. I just towed 16k on a gooseneck for the first time and everybody couldnt believe how well the truck performed........knock on wood.
@@SDRacing88 the highest mileage Duramax I have ever seen was 490,000 the most miles I’ve seen out of a truck was a Ford F350 and a ram both with over 1,000,000 miles on them
I call bullshit !!!!
Dead serious! Honest!! I couldn’t believe it myself!
@@MickelsonRacingChannel that's crazy. Normally you've got to bleed the system for hours.
I couldn’t believe it. I didn’t think there was a chance it would pop off like that, let alone run! After sitting for four years?! I didn’t even put fresh fuel in it!
fake
Thanks for the feedback!
Yeah, this ought to help ya. 🎉
