LU stands for “Lock-Up”. It’s the solenoid that controls signal pressure to the torque converter lock-up clutch.

I'll never unsubscribe to this channel because even if we wait months it's never a disappointment.
-
when you say, I don't know how much interest this video will get, I want to scream; PLEASE don't quit making your vids! Quit doubting yourself Pal. Your expression of technique & knowledge is well appreciated...even valued. Thanks again for having me and the others along.

These teardowns are therapeutic somehow. Not sure how or why, but they seem to add calmness and peace to interesting content.
-
The sheer scale of everything is amazing. Thank you for taking the time to film and describe your work.
-
I think you’re on the right track as far as the actual transmission problems. The valve body definitely looked bad when you separated it. It doesn’t take much as you know to cause issues with any kind of rust or debris in there. Torque converter should be a quick tear down and will tell the rest of the story. I hope you decide to make a part 2 to this. I’ve been missing your videos. Good to see you back.

The amount of work involved making each component and the fact it all works is incredible to me.
-
There was one problem with that transmission, the extra tool found inside. I vote to make this a series. Cool stuff.
-
It was amazing to see that transmission taken apart. You save us a lot of grief and time by excluding the arduous details. Thank you.
-
I love this channel, no stupid intro no fake drama and yelling. Just someone who knows exactly what they are doing so bada$$!
-
The ability of big gear to put in like >15 000 hours of work in absolute hell conditions yet still look like new will never cease to amaze me. It seems to me that 90% of major failures boil down to human error in some way, shape or form.
-
Every time I see things like this, I am just amazed by the amount of engineering put into transmissions. Simply amazing.
-
This type of video is why I love this channel. To see the amount of engineering, the amount of precision machining, the levels of complexity all to get one 40 ton Cat haul truck transmission to accurately shift through its gears and move huge amounts of dirt around mines and construction sites. It is a beautiful thing. And then we have our host's dry as hell well look at this shit here monolog, it's a great combination.

Couldn’t imagine the machining hours in that assembly
-
Please continue with the tear down and evaluation! Super interesting to see the 'inside' story on these machines! Thanks!!!
-
This Big stuff is just fascinating and very interesting. As a journeyman mechanic this is enormous yet complex. I also watch Western Truck and Tractor Repair and all of the heavy duty work that Warren does there. I've even worked a day with him. Great guy!! Thanks soooo much for going through this large transmission it sure give perspective to the work load that this equipment has to do!! All the best from Canada
-
It has always been a good day when he has uploaded a new video
-
Ya, keep going. It will be interesting to actually find out why they pulled it out of service. Another great video.
-
LU usually stands for Lock Up, at least in Allison transmissions, which is the friction clutch that engages the pump and the turbine of the converter together, making it to spin at the same speed of the engine. I dont even know if this transmission is equipped with that
-
Man. Idk why but I just have to watch your videos. I never owned, or never will own any construction equipment like that. But your knowledge and authenticity is special on YT so i'll always support.
