Shadowing Practice: NEW CUMMINS ZF 8 SPEED TEARDOWN - Learn English Speaking with Video

Hey guys, Nick over here at Randy's.

Today I'm going to be tearing down the new ZF 8 -speed power line transmission for you.

Getting this up on the bench, it appears this thing is heavy and weighs all over 400 pounds just like the new 10 -speeds do.

Also, it seems to be we're not using any dipsticks just like the ZFs and the 10 -speeds are currently not using.

Damn, what is it with these manufacturers and these new plastic pans?

There must be something I don't know.

All right, pan off on the ZF 8 now.

Looks like the filter's going to be integral to the pan

on these like they are on all zf8 speeds i have to find something else to figure

that out taking apart this valve body kind of makes me

happy i can see all the bolts appear to be the

same length that's not going to be a problem all right

now it appears with the valve body out we're running a

mechatronic system in these just kind of like the tecans and 8ls

and 6l 90s computers solenoids all integrated into one assembly on

this valve body digging into this pump cover it appears we're

actually going to be able to remove this thing a lot easier than prying

and pulling like a 68 cover she pops right out all

right looks like on the pump cover on the zf8 they

actually had to integrate a big bearing inside here to help hold that big converter they installed into this beast

and just a little bit something different we're not used to

here at randy's a remote chain driven pump they probably make a tool for this

but it appears a good old six cell smack the stator

trick gets this out real easy now digging into the meat

and potatoes on this transmission we're looking at the b clutches

here they seem to be pretty beefy like we're not going

to have any issues with these failing in the future

but it also seems like we have these anti -drag waverings

in here to actually keep the clutches from dragging after they

release getting even further into this to our p1 planetary it

looks like it resembles all the other zf8 speeds we've seen before we're going to keep digging into this

and see what else it looks like the input shaft looks

identical we got a reluctor wheel in there she looks identical even our p2 planetaries look just the same

so far everything resembles a normal zf8 speed next we're going to be pulling out this heavy c

and d clutch drum now

that we're going to start to disassemble this drum we're going to get to the e clutch drum

and where we're going to start to notice some differences in

how they do the eight speeds all right seems like for

you guys this is going to be a good thing on your trucks

unlike the 8 hp 90 and 95 and the hellcats

that took about a thousand horsepower stock before you started tearing

up this e -clutch drum they decided to upgrade it

and make it still in this setup

but what we're going to be starting to work on we're

in the process of working on right now it's a new setup of frictions and stills

so we can actually start adding some more holding capacity to

both of these drums now we're going to start digging into both the c

and e clutch drums and looking at the frictions

and stills frictions look like they're going to hold quite a bit same with the stills

but we know how you guys like more so we're going to find a way to add more

as we start to get into the tail housing we're going to notice

that it's a lot different than any of the other zf8 speeds we've seen where they integrate the tail housing

and the main case all into one

so it takes a little bit of different work to get this apart

but we got it as we were disassembling this main drum we did notice

that it is a lot thicker than all the other zf8 speeds out there on the road

that are prone to braking on disassembly

so they're trying to make everything hold a lot more torque

in these trucks opening up our output carrier we're going to get into our d clutches here

and i'm going to be quite honest i am fully surprised

on how well they built these units with the zfa speed

all torn down i have to tell you i am very

impressed cummins decide to throw a transmission behind their power plant to actually hold up

but we're going to make some things better for you guys stay tuned for what we have coming down the pipe .

How to practise with this video

Listen to the whole video once without speaking and note the words you do not know.
Start at 0.75× speed, shadow it sentence by sentence, then go back to normal speed once it feels easy.
Record yourself and compare with the original, paying attention to words like drum, clutch, dig.

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
