Great explanation I know there is more than one way but this is by far the best explanation I’ve seen two years after this video was made.. it’s way to easy to skip this part because the tubers wanting quick money don’t want to do a detailed video. Way to many camera movements and editing. Thank you for your time and knowledge sir.

I realize that you can just be rebuilding transmissions and making money, so I am all the more grateful that you take the time to make these videos sharing your knowledge and talent. 🙏

I like the idea of being closer to the minimum number vs the maximum because that will allow for wear meaning the clearances will loosen up slightly as the unit operates. If you are on the maximum side, once the wear sets in, if there is any, the gaps will be too large or out of spec in the real world. Thanks for the review Hiram.

Thank you for sharing your knowledge and all the extra effort and time it adds to the task. 👍💚

Thank you , Hiram! My nephew and I are building a Performace trans and where getting to this point and your explanation of this helps so much !

On the plastic shims i face off some bar stock in the lathe use double stick tape to stick shim to and can make custom shims.

Thank you for this info , just what I was looking for . You have helped me build many transmissions by watching your videos .

Thanks for sharing your knowledge and experience..

Thanks for another great video Hiram!!

Thanks for doing this end play video. Helped me alot in my diy build. Appreciate your time.

Awesome vato!! Miss your videos !! Hope you and your family are doing well!!

Hiram thank you for sharing your knowledge.

Keep up the good work, Hiram. I do quite a few 4L80's. I use a lot of Transgo products. But I no longer use those Blue hi temp rings on the center support. IMO, they are too wide for the grooves. And don't let enough fluid behind them. I had two units that I corrected a soft 2-3 shift. With only changing those rings to stock 400 scarf cut rings.

Move that wide gap in the snap ring around so it won't be inline with the wide gap in the case, a lot of transmissions have to have the snap rings go all the way across the the big gap in the case otherwise it makes big trouble for everything and of course R&R the trans again

The Sonnax 34322-02K fwd clutch hub is a great mod - it rollerizes the front and the hub is now supported by the direct housing and sun gear shaft instead of the main shaft. Skip the fwd to direct drum endplay checks ( there will be zero play) and you do everything with the pump selective as far as front end play. Ythese things want the front end play larger than the rear end play to allow each gear set to thrust independantly so the fwd movement of rear doesn't bring the load to the front gear set. .005 - .010" on top of your rear end play is a good target cleariance - so for your setup .010 to .015 would have been ideal for front end play with your .005 rear. I also like to install the plastic silencer ring that GM used to use on the output carrier but stopped using as cost cutting measure - it does help with wear on the bushing and noise. Great video btw

Thanks for the video sir. Happy Holidays

Gonna tryn do my 1993 izuiu 4l80 watched your other ones but always watch all Jimmy in Alabama

Grasias x el video Hiram desde North Carolina

Hiram I appreciate the video its valuable. if you don't mind me asking, what kind of labor do you charge for a performance build like this? thanks again

27:13 Are you sure on that bearing orientation? I'm looking at the instructions for the Sonnex 34006-SPB and shows it to install the opposite way you do.

Where did you source the four tab shim that your bent two tabs down early in the video? thanks

Thanks Hiram

Very nice video

Where can I put those tang spacers

Hi Hiram, it's me again. Off topic question here. I am dealing with at P0770 on a 2002 Toyota Tundra 4.7L. The code is for shift solenoid E. I also read that it could be the lock up solenoid. Well, I have replaced all three shift solenoids and tested all the wiring up to the control module and the wires are ok. However, I am still getting the same code. Now, my next task would be to determine if the issue is the Torque Converter or the Module itself. I was wondering if you have dealt with this specific issue with the Tundras and wanted to know if there is a common issue? Thanks in advance and once again, I love your content!

This is my Channel.🇧🇷🤝👍

The end play is checked without the pump gasket. Go read it again.

Thank u

The plastic selective shim under the pump comes in sizes of 0.059, 0.075, 0.091, 0.107, and 0.123 so I typically adjust my front end play using one of these along with a 0.010" shim under the bearing that rests on top of the forward drum if additional clearance is needed. I don't use the sonnax forward hub front washer 34298-078 or any other aftermarket washer that is thicker than stock to adjust front endplay, I use a new OEM 24241413 washer under the forward hub to retain the stock clearance in that location. So you are saying that if you use a pump selective shim like a 0.123 that it will raise the pump too high causing the pump sealing rings to not make proper contact with the overdrive drum? I have not heard of this. Have you personally seen this by marking the sealing ring with a dye and seeing if it did or didn't make a mark on the inside of the OD drum where it makes contact with the sealing ring?

35:20 only 2 video s explain this on KZfaq highly educational video

How much do you charge to do a 2004 GMC 4L 80e out of Denali I used your vehicles to rebuild One Transmission already I like what you're doing here and I don't have place to do it now so I would like to send it to you thank you

Hi Hiram! How are you?

Can I swap the larger input and clutches into a 4l60 that had the smaller input

Sonnax says push up on tail shaft to take out end play before taking readings on front end play. What are your thoughts? I appreciate your videos!

try this on one of your employees , see if they can follow this.
