The Fottinger transmitter, as it was than called, used water as fluid medium as it was first used for marine purpose.

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 .

@swift4856 Год назад

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.

In the late 70s Honda CVCC (if I recall correctly) had a 4 speed Hondamatic transmission, 2 automatic gears, then shift, then 2 more.

And who could forget the Buick Dyna flow that just used a special torque converter all the time.

There doesn’t need to be much clutch material because the fluid coupling transfers power until the input and output speeds are matched. The clutch doesn’t need to split like it does in a manual transmission.

Please, please do more of these educational videos my man - you are a natural teacher and these are difficult concepts for most people to understand properly - diagrams on a whiteboard aren't as helpful as seeing an expert with the parts in hand! 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.

@phTeamHalb Год назад

I've always been in awe with what the Torque converter has to accomplish - let alone figuring out the engaging and disengaging of the clutch, it needs to convert all the torque the engine is laying down to spin a shaft that can propel thousands of pounds under immense loads - just blows my mind. Thank you for this thoughtful explainer of how it accomplishes all that.

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.

@ExSkyCyclePilot Год назад

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.

@WJV9 Год назад

Buick had an automatic transmission in 1948 they called the DynaFlow. It was an extremely smooth transmission that did not shift but used the Torque Converter to change the fluid ratio from standing start to full road speed. The transmission had only 1 planetary gear for the Low Range that was manually selected and also a reversing gear for Reverse movement in the Low Range. My dad had a 1949 Buick Special with a straight 8 OHV engine with a DynaFlow transmission. The Torque Converter was not very efficient when starting so if you wanted to accelerate quickly it was best to manually select Low gear and then shift into Drive when your speed got to around 35 or 40 MPH. The smooth start in Drive was handy on ice/snow however since it accelerated gently and you would not get wheel spin so easily. Thanks for your description of the torque converter components and how they work, one of the best descriptions I have seen.

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?

I rebuilt transmission for right at 30 years, starting in 1972. Worked on both import and domestic, and all the way back to a 1947 Dynaflow and 1946 R Type Hydormatic. Oldest was a 1936 stick shift out of a Jaguar. Only thing I would like to comment on is the blue spots on the clutch surface of the front housing. Too me those blue marks are made by manufacturing when they attached the bolt lugs onto the pump cover. Each of the blue segments are arranged in at each point of the lug on the opposite side. It is possible that those did contribute to the chatter because of difference in hardening of the metal due to the welding process. Also, as far as thermal management goes, most heat is built up due to "oil shear" and to alleviate that Ford and GM would get the clutch engaged to stop the oil shear problem. That is why you put your car in park if you are stopped in traffic for any length of time. Back in the early 80's people would complain how "busy" the trans was.. I thought I was smart and set the valve body up to not allow lock up until in 4th gear (700R4) and found out after towing a few back into the shop (all burnt up) after going over Snoqualmie pass in Washington, because the torque converter was going into torque multiplication and building up tremendous heat from oil shear. But I digress..... Again, great video!

Thank you for thorough research. Could you at some point in time create a video for the most common issues with Lexus trunk locks not working, both with the remotes and switch. I have a 2006 LS430 that I cannot figure out. Yes, I've checked everything... And that car has more fuse box areas than any car I've ever owned. After 230k miles, something got to give.❤

@sruntdouble5933 not 100% sure but i believe there is a cancel button in the glove box for the trunk lid. check and make sure its not activated.

@stuntdouble5933 Год назад

@jluna1279 thanks, this model has it right next to the trunk open button left of the steering wheel...yes that has been looked at soon after we developed this issue a little over a year ago. thanks again

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.

@@jgn593 Same vehicle different name. Volvo bought Daf, short for daffodil. Still not "modern". My Justy had two computers. One running the clutch and ECVT, the other running the rest of the vehicle. And it was 2-door 4WD. Only 8 of this configuration sold in Canada. Manual for clutch / ECVT was 5 inches thick. Ask me how I know.

@@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.

@Judge_Dredd Год назад

@@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.

Must take my hat off to you for explaining in simple terms how a torque converter works. The guy who invented this was a genius. It's also had amazing engineers refining it to what it is today. It's so easy to take these things for granted. Never realised so many advancements had happened resulting in better fuel economy. Wonder how much difference there is now between advanced torque converters and traditional gearboxes when it comes to miles per gallon, especially when towing?

Wonderful invention. An interesting early type of automatic transmission was that Early VWs actually 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.
