MAJOR PROBLEMS with my 4L80 + First Test Drive & I'm probably crazy

- เผยแพร่เมื่อ 24 ก.ค. 2024
- It's time for the first test drive on the brand new 4l80 transmission on UglyTruck, the Turbo 8.1 Silverado. I was way nervous to take this out since it was my first transmission build and I had no idea how it would work out. When I first started it up, I noticed some kinda worrying sounds so I tore it back apart to investigate, and then cranked up the boost and took it for a test drive. Does it hold up? I'll let you be the judge.
The mods we did to the 4l80 include dual feeding the direct clutch drum, parts of a transgo HD2 shift kit to firm up the shifts, a stock separator plate with holes enlarged and some check balls left out, a new pump, all new steels, frictions, bushings, bearings, and pretty much everything. UglyTruck is a 2000 Chevy Silverado 1500 2wd thats been lowered 2/4, has the stock 8.6 10-bolt with a detroit truetrac, a freshened up 4l80e transmission, and a stock bottom end 8.1 big block with a custom turbo kit and an S480 80mm T6 turbo. Its a basic setup, and a ton of fun.

Being hyper vigilant to sounds, smells, and eyeballing gauges like a hawk is something I’m guilty of when I change something in my cars too lol. Great job on the trans rebuild man! Always a little prayer being said when doing that first startup and test drive afterwards.
Me too.
Prayer I don't know if professors use 🙏 prayer in their Thesis
I’m the same way. My Dad being a mechanic by trade for 40+ years had me growing up around cars and working on my own came with the territory. When I hear even the SMALLEST noise that I am not familiar with or a gauge does something it doesn’t normally do, his phone rings. He has grown accustomed to not answering my calls when he knows I’ve been working on something, because 99% of the time it’s me freaking out over nothing 😂
No need to apologize for providing us with great content! I am enjoying the 4l80 build and its progress! Hope to one day do the same for my truck
If I remember from my time dealing with this trans as well as other 1 ton autos you are hearing fluid pressure. High pressure fluid can make a whooshing sound. Doubly so with the mods done here. Nothing to worry about.
I hate when I hear something that sounds off. Then I can’t stop thinking about it. Nice work LT.
Ya I don't listen that hard and if it's still working Im good a while back I changed my rear diff fluid and there was chunks in the bottom but it was fine before and I didn't see what it was so I cleaned all that out and closed it and filled it back up and it was fine for a while but then a couple months ago it started skipping I was like yep that's the rear end and got a cheap lsd from Amazon and that was a whole nother ordeal but ya
Also
Lt “ sorry its been so long for this process”
Literally all of us cars still sitting in the same state as it was in 2 months ago lol. Your the man lt!
Lol some of our projects are just a long block on an engine stand at present! Car?? Wow man don't rush me!
@@concernedviewer2641 haha I definitely feel that
Mad props bro every one that rebuild something for the first time gets what I call the bubble guts and starts to hear things lol after the first one you fill like a pro. I got to give you props on pulling that trans in and out that's the part I would of probably lag on. Your videos make me want to attempt a rebuild your vary clear and easy to understand. Have a great one till the next one 👍✌️👌💯🥂 needs a good burn out now
Thank you for documenting the whole process! This was a great series of videos as always!
Glad you enjoyed it!
Congrats! Looking forward to seeing your future projects. I’m really interested in the AWD!!
The grin on your face when you were making those pulls says it all buddy - job well done!!!
Great content. I like that you don't edit out your concerns, just like most of us at home trying to figure things out.
I appreciate that!
Great video. And the realism. 👍
That is an accomplishment rebuilding your transmission in itself!! Congratulations on a job well done and that thing shifts great!! :)
Hey thanks!
Perhaps the pump mod or valve body bit you did made it louder. My 4l80e swap with circle D was a bit noisy. Still, great job. Funny, when I did long tubes all the clicking from now hearing the exhaust pulses freaked me out as well. I too learn the sounds of my cars
Awesome video. Turbo sounds amazing.
I think most of us that work on our own vehicles car relate to this! Keep up the great videos
I can totally relate to the "sound I never noticed before". Unless you've done several rebuilds on something like this, I think its inevitable that you'll have things that cause you to second guess yourself. Ugly Truck looks like a whole bunch of fun when the gas pedal & the mat comes in contact!😎😎
Yeah, fun is an understatement. Puts a smile on my face all the time
good for you ,sir!!!!!! nice ride!
You’re braver than I. I don’t touch transmissions and rear ends. Everything else I will do but I take those two items to people that do them every day.
That's Right if it's not something that you do every day, you'll do it 4 or five times before you get it ....Just The Way Tech IS
Amen
I like at the 12:44 mark you quote Hank Hill while getting on it. “Haha…. yep…”
Good job LT! Keep ‘em comin!
Always!
LT...don't be too hard on yourself man, takes courage to do a first automagic gearbox rebuild...the truck drives fine so you won that battle hands down dude.
Great customer service from Circle D.
Congrats. Great job.
Just curious how well your lock up worked.Between the different converters especially with the dual feed mod.Always enjoy your videos thanks for sharing your knowledge…
Glad I finally found someone else with a 4l80 swap. I should upload some footage from mine as well
Get well soon LT
It would a month of weekends to do the same job for me. Great job
When I bought my '05 Yukon XL 2500, it had the same low speed whine and I was certain my transmission was on its way to failure. That prompted me to call Jake's Performance and buy a new 80. Turns out the new one made the same sound, just a touch quieter. That was my third truck with the 80, but the first two had exhausts so loud I never heard the transmission 🤣
Also, I loved my firm shifts. It's like a good mule kick 😂
80Es are notorious for pump whine. I bought a used (previously rebuilt) unit and threw a circle d in it and had bad whine around idle. Drives mint and never has given me an issue, i gathered that might be the case from google. Also, highly recommend maxing all line pressures to 640 above 300ft/lbs for max clamping of the clutches at WOT.
My 200r4 trans in my grand national has a transgo shift kit in it with all fresh clutches, sprag, overdrive basket, billet input and ststor maybe? I'm not a trans expert, but, with my stock converter it was unpleasant to drive. It shifted way too hard but i wanted it as i make about 550 torque and 400 hp. I didn't want any slipping of the clutches. When i went from the 1700 stock converter to my 3200 stall to match my new turbo, i cant tell it shifts when i leave it in drive. You can hear them snap into gear but you cannot feel it at all. However, Get on the converter and into boost??? Oh boy you can feel it bang the gears. Shift it manually and it bangs the gears even harder. So i think you will really like it when you get your new converter!
better safe then sorry ! I would say if the pan a filter is clean when you swap the new converter in ,the trans will be just fine .🏁
I would be same paying more attention..., and I think being the exhaust leaked is fixed and now hearing more things going on.
I most say I feel your pain, as you said I need to take the transmission out,
If you figure out the noise you'll have to let us know what it is. As someone mentioned, maybe just line pressure in the trans if that's audible, I dunno. I'm not a slushbox guy. Anyway your work seems to have come together, shifts firmly by the looks of things. Good to keep in mind on cold pavement.
Great work.
Thank you! Cheers!
You're not an idiot! I always feel the same way when I tackle a new skill set and second-guess myself the whole way through. I always hear gremlins! LOL
Better safe than sorry when it comes to a “new noise”…..but love that blow off. Music to my ears 👍
Yeah, I try to be cautious
Next time you think of it hook up the scanner in hp tuners and go to the trans settings and set the force motor to max line pressure while you're sitting in the garage. it'll suprise you how loud the pump actually is at max pressure lol. if you don't have one invest in a line pressure gauge and verify before any test drives for peace of mind. definitely a good tool for troubleshooting as well. Looks like its working awesome nice job! They get easier every one you build...
Way to stay with it though! A lot of people would have melted down over this. It’s just part of it!
As a great man once said, there’s always time to do it right the second time.
The only transmission I ever rebuilt was a 4T65e in a Volvo XC90. I drove myself crazy afterwards chasing down noises. Turned out it was nothing trans related. One of the twin turbos had a rattling wastegate. Put a lot of miles on it without any problems.
Interesting, I didnt know s80s and xc90s had 4t65e transmissions. You learn something new every day
That’s a nice looking cluster right there.
I love the trans temp part as well.
The cluster looks REALLY nice!
LT I would call it job well done.
Mystery noises are the worst after a big fix... You're not alone.
Often when you have had work done on a vehicle you hear a lot of new weird noises THAT HAVE ALWAYS BEEN THERE 🤑
It’s the bane of all shops, you put air in a tyre and the client starts hearing rod knock and accuses you of wrecking their car.
I once put a new exhaust on my car went from single to dual and the same whirring noise started coming from my transmission. I don’t know if I simply never heard it before because it wasn’t there or that I could now hear it due to the new exhaust.
I did a circle d converter, bought in april. So far it looks like it might have tossed metal into my trans cooler.
Issue, brand new 6.0 build, and it's killing thrust bearings.
This is a 6l80, i'm a bit north from you.
I'm about to toss a new thrust bearing in there with my trans coolers bypassed. If it frys again I'm doing a new trans pump, new crank, and bearings. Of course new fkn balance job on the rotating assy... arg!
Oh and the trash i found in the cooler, looked like welding trash, maybe circle d didn't clean the converter very well.
Or it broke loose from high converter pressures due to me cheaping out and not replacing my radiator like my gut told me to do.
😑
Man that thing sounds good,I too have a 4l80 swap in my half ton,mine makes that exact noise,its a little louder when cold,but I think you did a great job rebuilding the trans buddy,and you did the right thing by following your gut instinct changing the stall, better safe than sorry buddy by a long shot,great job on the truck,I love those trucks like ours so keep up the good work,look forward to more videos
Hopefully nothing is wrong. It sucks you had to take the trans out so many times but sometimes you gotta do what you gotta do.
the 4l80e swap in my explorer has that whin. i kinda like it. 😂
A good video, after your first drive I can guarantee you were walking around with your chest all swelled up, a good feeling when you rebuild your own transmission.
Very true! a big sigh of relief once I saw it was shifting like it should
First thing I would have done is put it to the floorboard. if there was no obvious loud sound or hiccup or clunker... I would say don't worry about it. Been wrenching for 17 years. All of my toys I have treated that way because you're going to beat the s*** out of them. And my train of thought is if they can't handle it now they're not going to handle it in a little bit and were just wasting time. I may not turn the Boost controller on for the first day or 2 but gate pressure is a bar so. Go running through the gears if it can handle it and temps stay good don't worry about it.
I want a turbo my wife Suburban so bad especially watching you drive that truck.
Transmission rebuilds arent like engine rebuilds. If something was installed incorrectly or misplaced it wouldnt work off rip. Considering youre able to give it some power and it still shifts into all its ranges Id say its a success. In my experience a "break in" is about 1000 miles of regular driving. After that 1000 miles its good to change the fluid and inspect it. See what color it is and what kind of material may be in the pan. If its hella clean then youre good to go!
You could have had the hp tuners hooked up and you could see the line pressure & slip rate. 3000k then a fluid and filter change.
Be safe.
Chasing a red herring seems like a waste of time but, like you said, you need to know if its normal or not. If I rebuilt a trans and it shifted at all, I would consider that a win. Thanks for the video!
Thanks for watching it!
nahhh you did good, probably just doubting yourself. I think you did great!
Traction! you need traction! That is getting the power to the wheels much better than before.
yes, it does need that. This winter its gonna get a rear suspension overhaul that will help it stick a little better
Does that setup maybe have lockup and not letting it stall properly? Or maybe lockup is being engaged due to the increase in line pressure? Have you checked the datalog?
Good luck beating that 'rona, LT.
we're getting there
I don’t mind that it took a bit. I think some people watch TH-cam and they see people get things done in a 20 min video not knowing exactly how long stuff takes and they get discouraged when working on their own stuff because it take them a long time.
My torque converter actually growns at low speed due to the clutch material. Also, sometimes you can here a hissing, whoosing sound at partial low speed. Some converters use Kevlar clutches, which are grabby. You can hear the pump also. Normal. BTW I have a 4L80E I've been racing driving since 2017. Normal.
That’s good to hear!
My circle d and built 4l65 doesnt make that sound? maybe different fluid pressure on the dyno 4l80?
My 6L80 made a loud whining noise at a low speed cruise. After I had the fluid and filter changed, the noise went away and never returned.
could it be an exhaust leak? you didnt take it apart and back the last time?maybe a silicone coupler for turbo?
So I have a questions so I have a 1997 chevy suburban 2wd with a 5.7 vortec with an automatic 4l60e that started to go out about a year or two ago but when it was going out it started to read wrong on the speedometer so I went and got a used transmission put in it and it still read wrong well it went out in around 3 or 4 months do to sitting outside in the weather or maby from being out of an s10 so we had the original one rebuilt and we reused our censor that came with the original from the factory, transmission still reads wrong but if we put a new censor in it, it messes with the abs and won't shift so I don't know if there's anymore censors I can replace this all took place in a 2 to 3 year process and also when you really get on it it will either kick down to far and try to ride the gear out what seams to be a really long time or will start to jult over and over again and the faster you go the harder the jult and its a weird thing to explain like if you pump the gas paddle faster and faster what can I do
Totally get your concern but based on just this vid...send it. Did my own trans, a 46rh in my 93CTD...after me going thru it it has the reverse buzz these units are known for...not damaging to the unit but when I 1st heard it (cold weather only) I was kinda freaked. Long story short I have 15k miles on it (some of those not pleasant for the trans) and it's never skipped a beat....run that biotch hard imo.
the "send it" has been accomplished and we just crossed 100 miles on the rebuild this morning with no issues!
I bet they are not going to find anything wrong id put the new converter in and if it blows rebuild it again.
I have a 4l80 and it doesn't whirr or whine. Good luck.
Sounds to me like the turbo starting to spool
Great video today. Meticulous people listen and nitpick their own stuff more than others. Seems its real good
After a modification rebuild you will want to pull the pan and check the filter before you go much past 500 miles.
If you got anything wrong in the mods or re assembly you will notice abnormalities in the fluid and possibly evidence of damage in the filter. If you got something really wrong you won’t make it to 100 miles or possibly even out of the driveway.
just crossed 100 miles with it this morning. so far so good! but it will get a fresh fluid and filter change before too long
Remember that the bell housing its self is like a megaphone so any little sound that was hidden by the exhaust may not be so hidden now....o hell just stomp on it but carry a broom..........
Send it!
Man im a wood carpenter and i put some engineered flooring in the other day and i heard a pop in the floor and definitely thought maybe i missed putting some staples in or something and a guy who does flooring every day came in and was like no man that’s normal i have a fix but it’s probably going to make some noises every now and then lol.
Noises..... I Get it Man !!!!!!!!!!!!!!
Hey, weren't you ascared of debris in the old converter? I would of been after all that work to rebuild it.
I'll keep my fingers crossed 🤞 for you that there wasn't any contaminates in the old converter.
I probably should have sent it for cleaning first, but to be honest I didn't give it much thought at the time. Too late now I suppose, but the fluid from the old trans didn't look too bad, and most of the debris was larger anyway...
I got a 4l80 behind a turbo nitrous 454 in my half ton. Reverse is out. Gonna try to do myself
you should! the trans rebuild honestly wasn't bad at all, the worst part was trying to figure out what hydraulic changes to make
Your not crazy ! Just more curious/cautions as it’s your first build
We have all been there I’m sure
And you’ve fixed the slight exhaust leak so it’s all got a different sound happening
Lmao don't take everybody's comments to heart but we're all a little bit crazy just keep doing you I got mad respect for you
Dude. Im exactly the same. After i turboed my car i was.super.sensitive about noises. Drove my tuner crazy trying too.pick them all apart.
On that note my trans have all been fine. If a trans is fucked, you are going too *know* right away and the unit will burn itself up *quickly*. If.its shifting and not blowing through the gears, then its fine.
Btw this is coming from so.eone who burns.up a trans per year on average between my.cars.
I will donate some black mirror covers to get rid of the chrome mirrors.
It's the radio. Turn it on, raise the volume...profit!
It’s normal. Mine sounds the same man
My 4l80e with TransGo Kit and higher stall speed converter makes a whirring noise. I wouldn’t worry about it.
My 80e with 3200 stall makes the noise like that also I was going to get someone to look at it lol
Good to hear things sound normal then
I used to hear the same sound in a 1500i think it's normal
Just take it to precision transmission in Amarillo TX, won't be any problems after that...lol
I'm thinking it's good thing it's not a early Allison 5 speed truck cause the pumps are really noisy in them .
That 4l80 will take a beating . Give er he..
its stood up great to dozens and dozens of 1/4 mile passes at well over 1,000 lb.ft. of torque
Borderline harsh is perfect. You dont like it but the trans does.
Still Good Work You Do ! You Will Get it ! just the way u want With line psi Tuning Converter lock up My Hughes Trans Let Me Adj All Shifts & Tell me other Data too
Maybe you didn't hear it before because it used to whine from the chewed up teeth on the planetary gears.
Good job 50 miles drain oil ,slowly into full throttle after a hundred and a new converter
I'm not an expert but as far as I know you don't want to make hard pulls in drive. It's best to shift to D1 and go up as you make your hit. This will prevent overdrive roller clutch failure.
sort of correct, as long as you are in any position D3, D2, or D1 the OD roller clutch is backed up by a band. thats why I use D3 any time I do pulls
@@LawrenceTolman I know sonnax makes a kit that helps with the OD roller clutch if it's going to be used in drive.
Transmission pump my guess.
I want to swap my 1998 5 speed 2wd 4.2 f150 to a 4.6 where can I find info and parts id prefer to keep my transmission
not sure what would be required for that to be honest, but for parts your best bet would be to source a donor truck that has all the brackets, hardware, and wiring harnesses you'd need to make the conversion. it should be fairly plug and play if you have a complete donor to work with and rob parts from.
Before you do ANYTHING, drop the pan. If something is wearing or grinding, there will be debris stick to the magnet.
Some converter designs just make noise. You may swap in the stock converter, not hear the noise and think the new converter is defective.
The Coan 10’ converter in my Olds has a whiring noise when you accelerate, it’s been in the car 20 years, been cut apart and rebuilt once over its life. Zero problems. Your probably a little jumpy bring your first overhaul.
If you turn the radio up louder the noises go away!
Im only atb1:57 but my gut is telling me you need too overfill a little bit. Most guys iverfill by a quart or so
With the crap that went through your transmission originally I hope that you fully flushed your torque converter?
I did not even consider that to be honest. thankfully the old fluid didn't look too awful, but now I wish I would've flushed it
@@LawrenceTolman years ago I was granading a series of transmissions and the torque converter and cooler was full of metalic bits
I share your "anxiety" on newly assembled stuff...
lol dude u are action packed with issues
you're not wrong
Does this issue happen with the 4L60? you need to get a lift in your shop. I’m sure you can find a hydraulic lift.
not sure what the 4l60 would sound like... but yes I Do need a lift for sure
89👍's up LT thanks for sharing
