It's interesting to see that the torsion differential that was supposed to be a heavier duty design was completely trashed compared to the limited slip differential that had worn clutch packs where only the clutch pack assembly was worn. It seems that the clutch pack, although wearable, is more robust and serviceable as far as gear assemblies are concerned.

Could it jump start another EV?

There are 3.4k comments and I am sure one of them asked, would not be easier and better to just drain the fluid and add back the specified amount for the car you are working on? This way you can learn if it was overfilled, low, or okay.

Hi WeberAuto, great video as always, thanks for sharing this technical experience, extremely valuable information You're a great teacher, Mr. Kelly 👍

That was the best explanation I have seen on YT. I now have a much better understanding of all the differences. Thanks John Cheers 😊

You make great videos

What about filling it up with a large syringe? Isnt it much cheaper?

That’s an amazing video, what a great teacher! No idea how he mande me understand almost all of that.

I have a question, 2007 Yaris in HOT should I check it in Park or Neutral? This one has a dipstick.

Amazing video! Thanks a lot! My only problem: where I find this tools on Brazil??

Thanks for a great explanation. Here in the UK, MG have just launched their MG3 Hybrid+. It's made in China so you won't see it in the US. However, here in Blighty, it's the cheapest full hybrid on the market & it's a serial hybrid too with a decent 1.8 kWh battery. I'm interested in getting one but I do wonder quite whether the weight penalty you incur with all that extra metal outweighs the benefits. I regularly average 70 mpg with my 845 kg car. Would the 1300 kg MG3 better this? I suspect not...

Why in the world do automotive engineers design cars like this? It is so annoying. This video is very important for anyone who thinks that can change their trans. fluid in their driveway.

have this tranny in my 15 bmw 750li . i don't think the fluid is ever been changed. would you recommend a drain and fill with filter replacement or don't touch?

Everything is waaaaay too clean. So clean, I thought the bottom rod was super long 😆

HKHS (He Knows His Shit). Kudos to this guy. Thanks.

We need a video on how the ALL-WHEEL vehicles work. Up here in Colorado, we need FOUR-WHEEL drive often. Is this possible with these types of electronic transmissions.

Elon Musk wants to know your location 😂😂 (Love you professor)

Great for torque angle spec like on a crank bolt! Just remember to support the head and to not over tighten! YOU WILL SNAP VERY LARGE BOLTS AND FASTNERS VERY EASILY!

I'm a bit surprised the installation positioning and 'claibration' of the Resolver is so critical. Surely just needs to monitor rotation and not absolute rotational position, and if so its exact positioning wouldnt matter much? There obviously some subtle details I'm not aware of.

Interesting fact is that the only thing powering the vehicle when its going in Reverse, is MG2, as that thats the only thing that can power 'backwards'. There is no reverse gear. Well I guess that isnt a surprise as MG2 powers low speed forward and backward. A quick question - what happens when gear lever is in Neutral ? I guess its a fake neutral that effectively disconnects everything (except MG2) from the output shaft ? Regardless of if ICE is running or not. Handbook says in N that the battery doesnt charge even if engine running ie MG1 is not generating (compared to P with locked drive shaft and where MG1 is generating if ICE is running).

The transaxle oil pump only operating when engine (ICE) on, is presumably acceptable? As engine will be running in most cases when high load is occuring, and the lower load cases with engine off can probably be handled lubrication/cooling wise by splash lubrication. How about high 'reverse' load when MG2 is doing heavy regenerative braking and engine might be off? Hopefully the limited lubrication/cooling is still sufficient in that situation.

1:06:10 The MG2 stationary planet carrier being held by notches seems a bit crude (although cant see any better way to do it), and since MG2 can switch forcefully from power out to power absorbtion (generating), that planet carrier can get oscilating load backwards and forwards, and so could potentially 'rattle' in the housing. Slightly surprised there isnt something more rigidly holding it or 'damping' any potential vibration. Stephen, JDM Estima Hybrid 2011 with P311 transaxle.

At the start of operation, what percentage of battery charge is required when MG1 works?

It's quite an impressive configuration. More than the regular toyota one

This was so informative now I understand how eCVT of my RAV4 HEV work. Thank you 🙏

The Chevrolet Turbo Glide & the Buick Flight Pitch transmissions had a lot of problems.

Great job!

Excelente explicación, tengo una pregunta, en esta transmision es normal que el motor suba las rpm cuando por ejemplo se baja de D5 a D4? o cual puede ser el problema

Thanks!

So why the bad rep on there units, that's what you need to explain, how they fail and why....Javi G.

Brilliant lecture...

Want a superb demonstration really fascinating thank you.

You’re very informative love this video very much. I have a hot rod with a true track rear in a 1940 Ford Deluxe Coupe. H P 327 turbo 400 reprogramming kit. Almost completed. Few more items to put back on. From San Diego, California your fan!

Where can I read about the AISIN 8 Speed FWD in my 2019 VW Golf ?????

This is clearly the absolute proper method to remove/install Universal Joints. I have watched every " How to " video on UKposts and with a clear conscience, would feel guilty if I followed any video other than these! My interpretation is that if one uses any other method, its a roll of the dice! You may have no problem at all or end up going down a rabbit hole trying to figure out what went wrong.....I am grateful for this series! THANK YOU for the in depth data, facts, analysis, undeniable procedure!

Which system is better

my eyes are on a rav4 prime... but i still love learning about how teslas do what they do. thank you for sharing your knowledge!

2024. Excellent video.

thank you for sharing your great depth of knowledge .

My transmission is a 1986 Toyota pick up no identification on the transmission but I gotta stick her on the door and does it show that

Ingenious design...great presentation!

So we drain the fluid when car is running

For toyota Innova zenix hybrid which using P610 or P710 or P810. ?

want to hear more about “previously troublesome student” 😂

truly helped me understand why, even after disconnecting the front drive shaft, it sounds like gears are trying to fight each other. Perhaps my spring is failing on that darn fork.

Nice video well-presented, has a budget-minded stock car racer I do have to point out that you don't weld the spider gears to the side gears... What you do is simply fill in two teeth on the spider gear on opposite sides, thus preventing them from rotating past the spot where you filled in the teeth with the weld... So you do in fact get some movement between the two opposite tires.

Thank you very much for this instructural video. Since 02292024 i bought a second hand Opel Ampera-e, the equivalent of the chevy and was very curious after the batteriepack. Also in Europe they changed the pack and my 05292020 car was updated to 66kWh. You ended with “i am not a strong man anymore” Well sir, on the contrary, you are a mentally giant! Thanks again, Hans Both, Haarlem, The Netherlands.

Missed the Detroit or Grizzley "Ratchet Locker"

Are the 2024 CRV's still using this set-up. If not, is the new one better? Thank you.

Thanks, I concur with all the accolades below. Question, is the oil in the drive a separate system from the ICE oil? Assuming it is separate why don't change it or check it's level occasionally?
