4L80E Budget Build Part 2, Dual feed

Honestly, it's the coolers job to cool the fluid. If you are that concerned, get a bigger cooler. Having said that, the only conceivable issue to Me would be the heat treating of the aluminum alloy. Most aluminum high strength alloys are what's known as; "precipitation hardening." They take the part as cast and soak it at specific temperatures for specific times to achieve specific properties. The reason I mention it: Back in "The Eighties" there were three men who as dive buddies wanted their new aluminum tanks to match. They had them powder coated. The first ruptured while filling, killing both the guy and the shop owner. The DOT tracked down the remaining two and no one else died. Again, having said that, a 4L80 case is not a pressure vessel designed to contain 3000psi. There is no way I could imagine it making a difference at all. Not that big a fan of spending money to pretty up something you can only see on your back though. Maybe why I'm divorced.

[@flinch622]

I do not like powdercoating on aluminum - I've seen too many failures in a marine environment. The least bit of oxide always creeps and grows, the coating holds in moistue once there, and soon... it flakes off big time. I'd rather throw high temp primer and enamel right after an acid wash [like alumaprep]. That is a pain of course because the case must be fully stripped, bushings and all. A coat of alodine to seal it is tempting, but... I don't know if it gets along with transmission heat that well over time except it gets a good paint job over it. Work fast, and in a dry [sub 40% humidity] environment. I tested an intake manifold pre-treated with alodine last year - so far so good: coated on top with a high temp primer and a ceramic enamel. The surface before priming is excellent: truly squeaky clean.

Nice video. Doing a TH475 right now. You're correct, gloves are not for sissies. Professional Toyota Technician here, I wear several sets of latex everyday. Oh, and, powdercoating is awesome. I have some cerakote left over from another project...hmmmmm.

[@TheProchargedmopar]

Pretty funny, I got one of the clutch compressors in the mail about a week ago. Figured it would make my life a lot easier. C6 and 727 rebuilds coming up.

Yeah, I've done it with clamps, and it sucks lol

[@dairakaimenepada5336]

Thank you for these transmission video's.

My harbor freight snap pliers work just fine. Actually i never have a problem with my freight tools . to each there own

Any effect on converter lock up with doing the dual feed.Thanks for being real and sharing your knowledge..

None. Works the same.

I like the tool for the forward drum. I found that the white separator in a 24 pack of pop (Pepsi products) works great for lip seal tool. Kudos to Michigan 💪

[@pierre-yveslavigne9688]

I interested on the rollerised project...I'm doing it and putting the sonnax case bushing install backwards is too deep in transmission. I read that it the perfect deep to hold shim and bearing , but it not.. Whit the OEM thickness mesurement shimmed bearing...bushing contact the output shaft ....i have use tci 224400 kit...i will probably knock out just a bit the bushing or sand it...

[@TheDrivewayEngineer]

What year is your transmission? I know the earlier ones used a narrower bushing.

[@pierre-yveslavigne9688]

@@TheDrivewayEngineer my transmission is 4l80e 1998 from a gmc savana diesel. I checked the height of the bushing in the trans. I have 0.120...i saw on forum's 0.080 is the goal... i have check the float of the rear planetary and i mine is less than 0.010... What do you think about enlarging lubrication feed hole to 0.125 on the center support,overrun clutch housing and stator support ?

[@TheDrivewayEngineer]

A clearance of .010 is more than adequate, mine is only .006, you can go as tight as .003. .010 is usually my goal lol, so you nailed it. I do not open up any lube holes.

[@bigredracer7848]

powder coating is a personal preference if you like the way it looks of your vehicle have at it anyone else tries to tell you that it's going to be hard on parts and it's not going to do this it's going to help cause heating problems will guess what putting your foot three quarters of the way into the carburetor helps with heating problems well the radiators too small because my foot's stuck too far in the 1450 dominator believe me powder coating makes things look nicer heat is a product of using your toys if you spent all your money on the paint job and all well the motor transmission works I forgot to put a big enough radiator in there transmission cooler engine oil cooler I mean come on guys it looks nice powder coated oh yeah thank you for sharing

[@bigredracer7848]

every time you take that transmission apart to look at it it's foolish not to put new clutches in but you're trying to save money but I want to save time so by saving Time by putting new clutches in I don't have to take the transmission out in two years and replace them used clutches

[@richardarchuleta2399]

Do you replace the two rings that you removed and threw away. Just want to make sure that I fully understand your modification. I believe that the only stupid question is the one not asked. Great video. Definitely going to keep watching your videos. Many thanks

[@jasonkeith674]

I’m late to the game here, but I’m here👍. What kit do you recommend? I’m going to open mine up this week and gut it. Has 400-500k miles on it and I want to make it better than ever. Thanks for any info. Love the channel too. We have Pick’n pull down here in Texas, and I can walk around for hours.

im having one hell of a time drilling that dual feed hole. just went through 10 bits

I don't have any special tips, my drill bit was an off brand Ti coated like 98 cent thing. Go slowly and be patient.

[@mattrodgers4878]

Measure .410 in from the outside of the drum. That will put the hole just inside the seal surface.

Great video! I'm also in Michigan and have a 4L80e 4WD looking to convert to 2WD and rebuild. It's going in a 280zx along with my 5.3ls engine. I want to know what torque converter do you recommend for daily driving? Can you use to torque converter that came with the 4L80e?

Got prolly 6 layers of paint and I'm always running ice cold. Sooooo fuckem.

[@ryanodneal7001]

Doesnt the drum already have a bleed hole? Mines got a hole through very close to where you indicate to drill, that has as small ball bearing inside it...and another hole str8 through at the bottom of the wave disc seating area. Is this a rebuilt unit with an upgraded drum? Or factory? Should I still proceed with all the dual feed mods? Thanks

[@TheDrivewayEngineer]

The hole isn't necessar, just helps reverse apply.

[@amadeusgonzalez3]

What does dual feed do?

[@adamkorekach9936]

It applies the whole piston for third gear engagement. He explained it in the video quite thoroughly.

[@Nutflame55]

what is the plug for

[@darrenporsch]

I don't know about the heat retention issue but why would the OEM's spend money powder coating something that's aluminum so corrosion is not an issue. That extra money they don't want to spend building a car

[@TheDrivewayEngineer]

I don't know of any OE pwdercoated transmission cases. I did extensive work on the T1xx Chevy trucks, and everything we proposed powder coating got cut to existing in the end lol

[@prancstaman]

When you drilled the hole in the clutch pack housing or drum, does that make a constant leak when pressurized? Since it is in the area of the piston under pressure for engaging the clutches.

[@TheDrivewayEngineer]

Yes, which is the point of it. At high rpm fluid builds up there and starts to creep the direct clutches on, they drag a bit. The little .060 hole allows the residual fluid to exit, and never makes a significant difference to volume when normally engaged

[@Nutflame55]

but what does that mean? and why would I want softer shifts?

[@prancstaman]

@@Nutflame55 he's saying the pump provides more then enough fluid for proper engagement with the right pressure, plus still having the hole squirting out fluid while engaged. When not engaged then the fluid inside piston will drain out and not partially engage the piston. Same shift firmness to boot.

Hay jr my name is will newby iam 44 years old iam rebuilding a 4l80e out of a 92 Chevy truck 2500 HD 4x4 I have never been in side of a transmission for any reason I have worked on cars since I was 13 years old so i think I can do this the problem is the transmission lost reverse and overdrive could u give me advice on what to look for when I get I. There any help would be greatly appreciated I just don't have the money to pay for it to be rebilt

[@TheDrivewayEngineer]

Reverse is pretty common, usually due to the servo not contacting the band fully. Hiram Gutierrez has a great 4l80e video for a rebuild

What if I want to ls swap a mustang

[@TheDrivewayEngineer]

Depends on the year, but if it fits, it ships. Mustangs are pretty easy because they already make SBC mounts for most of them, so I'd just use those and the LS/SBC adapter plates like ICT billet sells. Since you're wiring it standalone, it doesn't care what chassis it's in, 12v constant to the oranges, 12v switched to the pinks, and fuel to the rails and it'll run.

Gonna be rebuilding my 4L80e thats going behind a 600hp big block chevy. I see some shops selling $900 perf rebuild kits. At what point are these necessary over a stock rebuild kit for $200 and the dual feed direct mod?

[@TheDrivewayEngineer]

No point really, stock clutches and a dual feed will take you to hard parts failure.

@@TheDrivewayEngineer thats good news. I picked up this used 4l80e, to replace the th350 in my 71 monte. Started shopping for rebuild kits, and coming across ones from jakes performance, monster, etc. Im like holy shit , nearly a $1k for a rebuild kit? Add 500-750 for a decent converter, another 500 for a trans controller, starts adding up quick!

@@joegarf they use good Raybestos clutches, and include the parts for the mods I did, but you're really paying for the name, the tech support they provide, and the convenience. You can get the same result for half the price.
