This is about the transmission type for cars. For other meanings of "AT", see AT.
An automatic transmission, also called auto, self-shifting transmission, n-speed automatic (where n is its number of forward gear ratios), or AT, is a type of motor vehicle transmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually. Like other transmission systems on vehicles, it allows an internal combustion engine, best suited to run at a relatively high rotational speed, to provide a range of speed and torque outputs necessary for vehicular travel. The number of forward gear ratios is often expressed for manual transmissions as well (e.g., 6-speed manual). The most popular form found in automobiles is the hydraulic automatic transmission. Similar but larger devices are also used for heavy-duty commercial and industrial vehicles and equipment. This system uses a fluid coupling in place of a friction clutch, and accomplishes gear changes by locking and unlocking a system of planetary gears. These systems have a defined set of gear ranges, often with a parking pawl that locks the output shaft of the transmission to keep the vehicle from rolling either forward or backward. Some machines with limited speed ranges or fixed engine speeds, such as some forklifts and lawn mowers, only use a torque converter to provide a variable gearing of the engine to the wheels.
Help us to make future videos for you. Make LE's efforts sustainable. Please support us at Patreon.com ! https://www.patreon.com/LearnEngineering The operation of an automatic transmission is explained here with help of animation. Allison-1000 transmission model, which has 6 speed and reverse is used for this purpose. The video starts with an explanation of planetary gear set. Just by engaging few clutch packs different output speed can be achieved in automatic transmission. A brief introduction of the torque converter is also given here. Here is the 2D version of the video. In my opinion this video is more helpful than the 3D video to understand the technology. https://youtu.be/Ugao6jTyM7k Like us on FB : https://www.facebook.com/LearnEngineering Voice-over artist :https://www.fi...
We thank our current patrons for saving LE from death. To achieve our goal of 2 video release/ month (addition of one more team member), please support us at Patreon. https://www.patreon.com/LearnEngineering The working of an automatic transmission is best understood with help of a 2D animation. This video demonstrates working of Allison 6 speed transmission in a step by step logical manner. Working of reverse gear is also explained here. A good introduction of planetary gear (epicyclic) set is also given at the introduction.
5 Things You Should Never Do With An Automatic Transmission Vehicle. Five bad automatic transmission driving habits. Is it okay to coast down a hill in neutral? Should you put the car in neutral when you come to a stop? What is the safest way to launch an automatic car? Is it okay to switch from reverse to drive while the vehicle is moving? What happens when you put the vehicle in park?

Visit me at: http://www.ericthecarguy.com/ This is part one of my front wheel drive (FWD) automatic transmission dissection video. In this video I cover the operation of clutches, bands, accumulators, clutch drums, the oil pump, the valve body, valves, check balls, seals and 'o' rings, as well as the construction and function of many of the internal hard parts of an automatic transmission. To be honest a rear wheel drive transmission isn't much different as many of the basic components are the same. I guess what I'm saying is that you could use the information in this video to have a basic understanding of a rear wheel drive automatic transmission also. It is just a basic overview of the main components. I don't get into theory and operation so much. Just the general operation and i...
This animation explains the principles of automatic transmissions that use a Ravigneaux planetary gear set. Contents 1) Torque converter, multi-plate clutches 2) Multi-plate brakes, band brakes 3) Ravigneaux gear set 4) Large and small sun gear 5) Planets and planet carrier 6) Ring gear 7) Gear ratios
This is a very detailed explanation on how the gears of this automatic transmission converts the rotation of the input to those 6 speeds and reverse, using 3D animation. I didn't explain how the real clutches works so watch this video if you are interested on that: https://www.youtube.com/watch?v=TcYsV063lk8 Here you can download the model for 3D printing: http://www.thingiverse.com/thing:1094616

The Allison 1000 is built by Allison Transmissions, a General Motors owned company. This tansmission is typically used in 2001 and newer Chevrolet Silverado and GMC Sierra Heavy-Duty C and K series pickup trucks with the Isuzu 6.6L Duramax engine. This transmission uses a simple planetary gear set to drive a Simpson planetary gear set (common sun gears). The following summarizes the changes to the Allison 1000 over the years: (2010 Uprate) MW7 - Strengthened to handle the higher torque capability of the 2011 model year Duramax LGH and LML engines. 4th Generation MW7 - Added 6th gear and other software refinements in 2006...

Components from the Allison 1000 Transmission were used in the majority of this video. We teach current vehicle technologies to our automotive students at Weber State University and online.

The 1st step in rebuilding an automatic transmission is knowing how to disassemble it properly. Watch as I take apart this rear wheel drive Ford 4R70W automatic transmission out of a 2011 E-250 van. Videos on subsequent steps on how to rebuild this transmission are coming soon, stay posted and subscribe. A video to rebuild this unit can be found here https://youtu.be/3WdVTSCM0PU
On this video we can see the disassembly of a 2006 4L60E transmission. The most common failure on these units is 3rd. clutch burn up, the reaction sun shell and the 2-4 band. Failure on these transmissions is not necessary the way it is treated, rather is these common or pattern failures. Valve body ware is also another issue and can be corrected installing a correction kit of your choice.

This is a video of a 4L60-E Transmission complete disassemble and rebuild. You will recognize the first half of the teardown, the rest I had misplaced it but found it, so I put it all together as one video as I intended to do a long time ago. And yes, it's an old video.
