4l80e Teardown and Inspection Extreme Automatics Trans Brake Manual Valve Body

The lord’s work!

[@christophersanders5007]

in my early model 4L80E build I was not able to use the Sonnax forward drum hub roller bearing. It was too thick, and took away all my input shaft end play. The Sonnax web site does say machining may be required to use that. I just replaced the stock plastic washer those hubs use with a copper washer that came in my rebuild kit.

[@dreece2000]

I thought about buying you some torque sockets

[@igotfiveonit8562]

I have to build my 4l80, what would you say this trans build is capable of handling? thanks for the videos!

[@BlaserBuilds]

Should be able to do 1000hp pretty reliably.

[@tonysellars6112]

Great video

[@BlaserBuilds]

Thanks!

Hello,Ryan! Can you give an advice where to find the problem: I can hear mechanical sound(like pleantary sound) in the end of 1st gear until it shifts to 2nd.starts from 1500rpm if moving slowly, more gas - lesser sound. 1.I have changed 2 oil pumps(no any damage was noticed) and filters with seals. 2. 3 times i've changed overdrive planetary(now billet inside) with new roller sprag spring retainer and snap ring 3. Converter(triple disc with lock up) was also checked and balanced - no damage was found 4. Flexplate to TC also checked 5. all bearings, washers,bushings&seals are changed. 6.Diff also checked Where else i can check to find the problem?

[@BlaserBuilds]

Hmm that's a tough one.

[@alexsoteynykov3492]

@@BlaserBuilds can it be caused by too low or high line pressure? Ihave sonnax hd2 booster kit

[@BlaserBuilds]

@@alexsoteynykov3492 Is it a whining sound? Or metal on metal?

[@alexsoteynykov3492]

@BlaserBuilds it sounds like metal planetary squealing accelararing noise. Like when big bus trying to accelerate hardly.

[@scotttimpany2845]

Gotta make you feel good that you built it and it stood up to 8 second Volvo power. Those pieces and parts looked great. Quality parts and careful assembly yo!

[@scotttimpany2845]

Come to think of it... makes ME feel good that the transmission looks great. I followed your vids closely when I rebuilt mine.

[@emccolly]

I reckon it's GM powered, not Volvo.

[@LynnTwinCustoms513]

Good find! Everything else looked minty

[@brianhavinga295]

Hell yeahhhh boiiii

[@79huddy]

So what's the fix so it doesn't munch the new pump is he changing the converter or changing the lock up or both I'm intrigued transmissions are not my playpen and are an expensive learning curve if you fudge it

[@BlaserBuilds]

Not going to do the 3rd lockup.

[@davidgonzalez9785]

Hi did you leave the center seal out for dual feed modification on the Forward drum? Thanks

[@BlaserBuilds]

No, but you can. It's just not part of dual feed. The forward drum seal has a bleed hole and applied the whole drum anyways. Just slows fluid to prevent harsh shift.

[@cameron878]

Jake sells th400 style intermediate piston return spring plates. We use them in all 4L80e builds, they don't dish outward like the stock 80e ones do. Then we pull 6 springs off the stock retaining plate and put them in outer holes in the 3 separate locations. Looks like a pretty decent build and nothing really got hurt. Also, that chamfer on the rev band seems normal if my memory serves me right

[@BlaserBuilds]

Yeah, the new band that went in was the same way. But not sire where the black gritty stuff was coming from. I guess we'll see how it goes, lol. I'll check out the th400 plates for the next one.

[@christophersanders5007]

I added that same plate from Jakes in my 4l80e rebuild.

[@pedricktownperformance6781]

The stock 4l80e intermediate piston retaining plate is known to flex and bow with elevated line pressure. I use a thicker th400 retaining plate with the 4l80e springs to fix that problem.

Very good content!!

Thanks!

[@TurboLSRanger]

Crazy that thing was still a stock ecu

[@funfun8095]

It's not an auto shift.

[@BlaserBuilds]

Yeah, and same SBE in the car for like 4-5 years.

[@brianhavinga295]

​@@funfun8095 it was for 99% of the time

[@funfun8095]

@@brianhavinga295 I thought that T brake was manual only...so ecu wasn't controlling shifts. I thought only Jake and CK had auto shifting T Brake VBs.

[@brianhavinga295]

@@funfun8095 correct but it only had that. Valve body for a few months for 5+ years it was autoshifting running low 9's foot brake only

I have a ea valve body in my 80e a buddy of mine had specd from Lonnie. Has lockup in 1-4 and he’s done a few like that actually. But only time they have been used like that is in a diesel application and I talked with him about it over the phone and he seemed to think that the lower rpm of the diesel is what keeps the pump alive with lockup in every gear. Who knows tho

[@ratchetstrapgarage3609]

What do you think caused the rubbing/beveling on the reverse band.

[@BlaserBuilds]

Not sure TBH... theres really not anything there to rub it like that.

[@funfun8095]

Why did you run wave plates? I toss all those in performance builds. I also put the forward hub in, then the clutches. Easier than having to wiggle it in. ;)

[@BlaserBuilds]

Forward, just maintaining a stock clearance stack and the drum is applied all the time in forward gears so I don't feel like there really much to gain by removing it, unless clearancing for another clutch, and it doesnt apply/release under power. I kept the intermediate just to soften the impact on the intermediate sprag on the 1-2, also stock clearance stack. Direct I removed it to clearance the drum for 6 clutches, and it applies under power.

[@TurboBobBailey]

What kind of pan is that? Nice followup vid BTW.

[@BlaserBuilds]

Stock pan

[@brianhavinga295]

Stock early 80e pan. They hold a bit more and use a slightly different filter

[@twiztid83222]

Where do u find the time to do all this? I can’t even go in my garage for a beer without getting looks!

[@BlaserBuilds]

I was doing youtube and working on cars before we met, so it's kinda always been the way. But consistency is big, do a little bit every day, or as much as possible. After work(10 ish hours) I can get in like 2-4 hours a day without really interfering with any family time, or house work throughout the week. This teardown, and editing the video was maybe an hour and a half.

@@BlaserBuilds Well after my work is done at 6:30pm 12hr day. Come home watch my son while she cooks then we eat. Then she takes 1hr to clean a kitchen with 5 dirty plates. 🤷‍♂️ 😴 I’m still looking for a c10 project but ppl want 15k for a junker. You should upload a old video of when you first started doing car audio lol. I miss my old systems but I rock a van now. Still have it in garage.

I have a question Have you noticed anything with filter starvation using the stock pan when launching

[@BlaserBuilds]

I have not. But I'm also not measuring for it to see if there's a drop in pressure or anything.

[@edwinrosadojr4592]

@@BlaserBuilds just something I see floating around on the forums about that being a possibility. But I haven’t heard anything from you, Matt or even Cameron mention anything about it
