@@rockroll9513 Different plates, but it does only the whole woth the plate. I have a video on recal kit also. Always follow instructions as supplied with the kit.
Of all the 4L80E assembly videos I have watched this is the first one to mention that the sun gear tube lube hole needs to be lined up with the sun gear notch.
I enjoy a quick transmission rebuild myself. Keeps them a little more in my brain since I don't build them very often. Really looking forward to the Mustang corrections. Can't believe that tune was that far off, sure hope it wasn't driven much but from the look of that fuel line, it's got some miles on it.
The forward seal can stay. It has a bleed hole so fill both sides anyways. That seal is just meant to slow the forward apply so it's not so harsh, but the full piston is applied all the time in all forward gears. I've left it out before in my th400, and using the aluminum piston, the seal isn't large enough to seal anyways.
Where do you get the cup plugs to block the reverse feed? No parts stores around me had them and I had to order brass ones off Amazon. It was literally the only place I could find them
Just to get this straight .when doing this dual feed mod I can use the ske4l80 kit (non hd) or is there another base shift kit like the superior or other that will work best doing the dual feed
Any idea what might cause lock up drag when transmission is cold? So 4l80e with circle D triple disc, locked up solid when cold, when it hits about 100 degrees you can put if in gear but still drags, 130 and above works like it should.
I have a video on EA install too. I've used the power packs, but there is some concern with the thickness of the steels to get the extra clutches in. They are something like .060, whereas stock steels are .072ish or .080. I like to not go thinner than the stock forward steels which would be the .07x thickness. Aluminum piston machined can fit an extra clutch in direct with forward steels.
I watched another video on the 4L80E from a reputable transmission shop and he said if you remove the second ring and or the center seal in the direct drum it will stop the lockup from working. Is there any truth to this?
@@TheMasterofsparks Interesting just watched it. He might have been thinking of a different transmission. Removing the seal is required for dual feed, and in all trans brake instructions I've used. I've never had one that didn't have lock up from removing the seal.
Would you still recommend doing the plug even when using the Jake’s D3 trans brake?
No. The Jakes D3 is a true dual feed through that whole, but it blocks the reverse passage with the plate You should not block the case with the D3.
I show that in this video.

@@BlaserBuilds Thanks just making sure
@@BlaserBuilds what about Jake's Performance recalibration kit? Same plate?

It never gets old watching you build transmissions.

Could you link to a rebuild kit that you recommend. Been looking for parts for my first rebuild.
Thanks man for sharing your knowledge..

Dose the pressed in forward 97 up inner sleeve lip seal stay in when dual feeding..?Nobody really talks about replacing it or just removing it..Thanks

@@BlaserBuilds thanks for the info…

Parking pawl cup plug, or 3/8 cup plug 0.375" OD. They some in some rebuild kits too.
Recommend stiffer springs in the direct when dual feeding.

Do you gotta plug the case with that plug when doing a jakes d3 also ?
No. The D3 is dual fed through both holes in the case. The valve body fluid path is reworked, and has a custom plate to accomplish this.
Awesome video! Thank you!
So you leave the lip seal out of the drum??
Correct, no 2nd sealing ring, and no lip seal.
Would love to see an in depth d1 transbrake install
Maybe some day if someone wants one done.
Appreciate the video im buying the extreme automatic 4l80 trans brake valve body any more tips? What do you think of the alto power packs?

@@BlaserBuilds interesting thx. where you able to get the trans temp sensor working with the 3 prong 700r4 plug?
What fluid do you use?
Usually Valvoline Dex-III/MERC blue bottle.
I watched another video on the 4L80E from a reputable transmission shop and he said if you remove the second ring and or the center seal in the direct drum it will stop the lockup from working. Is there any truth to this?
No, the dual feed won't effect the lockup. If the lockup O-ring on the input shaft is missing it won't lock up though.
Do you have a link to the video?
Precision transmission channel.
Video title. 4L80E day, but it’s not this 4l80e’s day enjoy…
