A much appreciate this man for his clarity of mind in explaining complexity in a simple way…..Thanks The German inverter of the torque converter was Dr. H Fottinger. The first experimental converter was build in1908 and gave the maximum efficiency of 83% with a maximum torque ratio of 5:1. The Fottinger transmitter, as it was than called, used water as fluid medium as it was first used for marine purpose.

When I was a motor mechanic apprentice over 50 years ago automatics were not as ubiquitous as now. We were not taught to service or repair them - they were left to specialists. We were just told they had a fluid coupler. I am learning so much from the Car Care Nut! And this video gives another reason to do regular ATF changes (as opposed to so-called lifetime fluid).

Don't forget the engineers who designed them overtime with trials and errors in order to come up with this. And what we often don't see is the fact that what we consider as modern technology such as this (TC) has often been around for a long time ago back when there was no AI or computer-assisted designing, it was all about brain cells, eyes, hands, pencils and drawing board. We take it for granted but often don't think about the brilliant minds that made our lives much easier.

Back in the early 50's Chrysler had a "Fluid coupler" attached to a standard transmission with a manual clutch. You could shift the gear selector as a regular gear box. The only thing different is that you could select a gear and then NOT depress the clutch and the engine would not stall. The coupler would take over and you could operate the car as an automatic. It never did catch on .

Hi Yes I worked on early Volkswagons who had a similar thing. Early VWs had a manual transmissions with both a clutch and a torque converter but the clutch had no clutch pedal. The clutch was activated from the gear stick and it simply was fully engaged or fully disengaged. The clutch was engaged by pushing the gear stick down (which disengaged the clutch) before pushing the gear stick into gear and letting the gear stick up (which engaged the clutch again) while the torque converter kept everything separate until accelerating. It was known as a stick shift. I also wondered why it wasn't more popular.

@@Maybe-So I think Chevy had an automatic transmission you had to shift once manually. It did not catch on. They went back to the automatic. Also, Chevy had a special transmission that shifted gears through use of a special converter. Finally had all the bugs out of it and worked great only to be discontinued. And who could forget the Buick Dyna flow that just used a special torque converter all the time. They worked super smooth but was a gas hog.🙂 The famous Hydro matic transmission never used a torque converter at all just a fluid coupling. One model of Hydro matic had two fluid couplings. 😉

The genius of your teaching is starting with the idea and then dealing with the problems. Most tutorials would simply explain what each part does, but if you understand the problems that inventors had to overcome, then you really start to understand the interaction of all of the parts.

Awesome video from a retired heavy duty diesel mechanic. The one thing you talked about and we all know what happens inside a automatic transmission is-but we cannot see it is torque converter creep at a stop and low speeds. Their is a way-!!. On heavy equipment that use a torque converter assembly separate from the transmission but connected by what we call a trans-converter driveshaft you can actually see this principle working. Decades ago when I started working for a underground mining equipment manufacturer all the machines where set up this way. The first time in the shop that I watched this happen; I was totally memorized. Thinking that is cool to watch the trans-converter driveshaft do it’s thing. I never got tired of watching that trans-converter driveshaft spin and do it’s thing. It’s almost memorizing to watch as the engine speeds up and down. It’s totally fascinating to watch and see that principle of a automatic transmission in action. I tried to find a video of this setup but failed. Maybe a heavy duty diesel mechanic that works on underground mining equipment that reads my comment will make a video of a mining machine’s trans-converter driveshaft in action; it would be great. I’m long retired out of the business. But it is totally fascinating to watch.

I remember when locking torque converters started showing up in the early eighties, and when going up a grade, those early converters would lock, unlock, lock unlock, every few seconds. People would climb under their cars and disconnect a wiring harness on the side of the transmission to keep the converter from locking. This was a common issue on GM cars and trucks, which usually had large V8 engines, and the locking torque converter made little difference in the gas mileage anyway, so people didn't mind disabling the converter lockup.

Oh how I remember my 85 El Camino with a torque converter lock-up problem. It locked up way too soon (around 27mph) causing the engine to lug. I had to go into arbitration with GM to get it fixed - at another dealership - who did finally fix it. On that El Camino, it shouldn't have locked up before about 38mph. But the first dealership tried to tell me it was normal - "they all do it" BS.

Ha! Torque convertor shudder. A highly predictable occurence in Towncars, Grand Marquis, Fairlane 500's, etc. from 2010 and earlier. And usually at about 45,000 miles. Customers usually had difficulty describing the sensation, but this being Texas, I always asked one question. "Did it feel like you had just run across a cattle guard?" (Those steel tubes in a frame running laterally across a dirt road where it crosses through a fence) "EXACTLY like that," most would say. At that point I would explain that deteriorating fluid was to blame and sell a transmission flush. That took care of most all the cases but occasionally they were too far gone and a new convertor was the fix. No salesman would dream of mentioning that flush as preventative maintenence, but despite it not being listed as such in the owners' manuals, we recommended it at 30,000 and cars that received that operaton never developed the shudder.

@@zacinnc78 We never had a new one with the concern. It took some time for the fluid to deteriorate to where the clutch took several rapid applications (generating the noise) before it would hold. I've never had a look at a Toyota lock-up device so I can't speculate on a cause. When I use the term clutch, it's because the Ford unit really was a miniature pressure plate/disc thing, good to transmit only enough torque to pull the vehicle through the air at a steady speed. Ask any more from it and it unlocked. I think Toyota owes you a new one if you're still in warranty, and being a 2022, it should be. Doesn't powertrain wty go to 60k?

My 1990 Subaru Justy was the very first modern production vehicle to use a CVT. Subaru called it the ECVT. The transfer of power from the engine to the ECVT was via an electromagnetic clutch that was activated by a switch on the accelerator. Very cool. I prefer it over a toque converter.

@@TheScrubmuffin69 Flooring an auto is underwheming, not involved, wasteful, and boring, and a manual is more than just changing gear, you can better balance the car through corners and bends, through hazards, in poor weather, and also change your driving to short shift for economy. There is a reason why racing cars are manual, there's a reason why advanced car control is best achieved in a manual, there's a reason why emergency vehicles here in the UK are manual and driver training is so long, strict, and advanced. Automatics are for beginners and the lazy, people who think they can drive and discover they can't, and that is why we have two separate tests for manual or automatic, pass an automatic driving test and you're only allowed to drive automatic cars, pass a manual test and you can drive any car, because you're better trained, and a better driver. Countries that think there's no difference between the two, and think automatics are better, have worse per capita, per mile, death rates on their roads, because people aren't trained properly to drive.

@@2148aa I would argue I could steer better with my knees than anyone that drives an automatic using their hands, and so can my wife, because we're more aware of the weather and road conditions, and more aware of hazard perception, and skid control. Theory and training, starts with learner plates and a qualified driving instructor; just that and I would argue any UK Driver is 'advanced' compared to any US Driver, even your US Police. In terms of advanced training in Roadcraft, skid pan, off-road, and emergency driving using commentary in front of an advanced instructor, then we're incomparable. It's not just giving 'a man something to do with his hands', our women are better than you as well.
