Toyota Production System

A production system which is steeped in the philosophy of "the complete elimination of all waste" imbuing all aspects of production in pursuit of the most efficient methods.

Toyota Motor Corporation's vehicle production system is a way of "making things" that is sometimes referred to as a "lean manufacturing system" or a "Just-in-Time (JIT) system," and has come to be well known and studied worldwide.

This production control system has been established based on many years of continuous improvements, with the objective of "making the vehicles ordered by customers in the quickest and most efficient way, in order to deliver the vehicles as quickly as possible."

The Toyota Production System (TPS) was established based on two concepts: The first is called "jidoka" (which can be loosely translated as "automation with a human touch") which means that when a problem occurs, the equipment stops immediately, preventing defective products from being produced; The second is the concept of "Just-in-Time," in which each process produces only what is needed by the next process in a continuous flow.

Based on the basic philosophies of jidoka and Just-in-Time, the TPS can efficiently and quickly produce vehicles of sound quality, one at a time, that fully satisfy customer requirements.

Improvement of Toyota Transmission time to time

Corolla Transmission first generation to eleventh generation

In first improvement we will see how they improves corolla transmissions until the latest generation

The Toyota Corolla is a compact/subcompact car that, in 1997, became the world's top-selling nameplate; more than 35 million Toyota Corolla vehicles have been sold over the past 45 years.

Sports car technology was adopted for the transmission, and the vehicle was equipped with a 4-speed fully-synchronized manual transmission with a floor type gear change lever. This marked the first time that this type of transmission was adopted in a Japanese vehicle, and a sporty, direct shifting feel was achieved. In addition, Japan's first floor-mounted 2-speed automatic transmission and a steering column-mounted 4-speed manual transmission, already familiar in other vehicles, were made available.

Toyota Corolla is among the best of the compact sedans: reliable and economical yet refined and comfortable.

Featuring a 4-cylinder engine and front-wheel drive, the Corolla is available with either a 5-speed manual transmission or a 4-speed electronically-controlled automatic transmission. Known for its smaller size, reliability, affordable pricing, and excellent fuel economy, the Toyota Corolla is considered to be a great starter vehicle but is not a good choice for a larger family. 

The standard four-cylinder engine revs smoothly and delivers good acceleration performance. Corolla earns an EPA-estimated 32/40 mpg City/Highway when equipped with a manual transmission, while the automatic gets 30/38 mpg.. Both the manual and the automatic transmissions offer smooth shifting, and the manual is very easy to operate. All models have a smooth, comfortable ride and responsive handling.

The new Corolla Axio is available with either a 1.3-liter 1NR-FE or 1.5-liter 1NZ-FE four cylinder engines; front or all-wheel drive. Both 5-speed manual and CVT transmissions are offered. The 1.3-liter engine and all-wheel drive variants are available only with the CVT transmission. The Corolla Fielder is available with 1.5-liter 1NZ-FE or 1.8-liter 2ZR-FAE four cylinder engines mated with a CVT transmission. The 1.5-liter is available with front and all-wheel drive, the 1.8-liter is offered only in front-wheel drive.

Eleventh generation (E160) 2014

The base model Corolla L is offered with a four-speed automatic transmission or a six-speed manual transmission. The six-speed manual is also available in the Corolla S.

A six-speed manual transmission is available on the Corolla L and S grades. Drive modes that offer re-calibrated throttle, transmission and steering responses are available on the Corolla LE Eco and Corolla S. For ECO drive mode on the LE Eco, the initial throttle inputs are less sensitive to help encourage more fuel-efficient driving and eliminate sudden starts. On the S grade, the SPORT mode software helps make the accelerator pedal feel more responsive to input along with CVTi-S shifting logic that enhances acceleration feel. In sport mode, Corolla's electronic power steering is programmed to offer a more positive steering feel.

The unibody makes extensive use of lightweight, high-strength steel to help keep vehicle weight below 2,900 pounds in the interest of fuel economy. In addition to improved collision performance, such construction also gives the Corolla's structure increased rigidity to optimize chassis and suspension performance, giving the new car a more responsive and engaging driving experience.

That is for corolla transmission improvement. Continue with other models next time

DODGE TRANSMISSION TECHNOLOGY (AUTO STICK)

AUTO-STICK

The name Autostick has been used both for a Volkswagen semi-auto transmission and a system designed by Chrysler which allows for manual selection of gears with an automatic transmission. Another similar system designed by Porsche is called Tiptronic. These systems are also called "Manu-Matic" transmissions.

Auto-stick that use at Doge Challenger

History of Auto-Stick

This system is made by volkswagen company, then is used by dodge. Volkswagen Autostick Officially called the Volkswagen Automatic Stickshift, this transmission was a three speed manual transmission connected to a vacuum-operated automatic clutch. When the driver put his/her hand on the gearshift the clutch would disengage by a 12 volt solenoid operating the vacuum clutch, allowing shifting between gears, once he/sheremoved his/her hand the clutch would re-engage automatically. The transmission was also equipped with a torque converter, allowing the car to idle in gear, like an automatic. The torque converter was operated by transmission fluid. This would allow the car to stop in any gear and start from a standing stop in any gear. This transmission was first available on the 1967 Volkswagen Beetle, and was made available on the Karmann Ghia in 1967. VW dropped the transmission option altogether in 1976.

Newer Volkswagens use a Tiptronic and DSG system. In the other hand,The Dodge Intrepid ES and Eagle Vision TSi were the first automobile models in North America that came equipped with the Autostick system as an option, later standard equipment on the 1997 Plymouth Prowler and 1999 Chrysler 300M. It was added to the JA cars on the 1997 Stratus. This system was standard on 1999 to 2003 model year Dodge Grand Caravan ES, but only the front-wheel drive models since the AWD used a different TCM. Many Chrysler models today come with this system, including the 300, 300C, Charger, Challenger, Sebring, PT Cruiser, Crossfire, Pacifica, Chrysler Town & Country, Dodge Avenger, Dodge Stratus R/T, Dodge Journey R/T and SXT and Dodge Grand Caravan.

Component of Auto-stick

Basically auto-stick component is same with other transmission,but with additional movement at the gear lever 

the gear lever need to put at D then can shift up or down

System operation 

Components of the Autostick system in the first Chrysler vehicles to have the design included a different TCM (Transmission Control Module), shift assembly, and gauge cluster. The gauge cluster includes a read-out to let the driver know which gear is selected.

The system works by dropping the shifter down into a gated area on the shift assembly which allows the shifter to be pushed to the right (up-shift) or to the left (down-shift). When the driver pushes the shifter in either of these directions the assembly sends a signal to the TCM to shift up, or down depending on the driver's actions. Dropping the shifter into the Autostick gate while the vehicle is moving will simply keep the vehicle in the current gear selected.

For the column-shift third- and fourth-generation Dodge Grand Caravan ES (1999-2003, Front-wheel drive models only), the system is activated and deactivated when a button on the end of the end of the shifter. Gear selection is executed via a toggle switch mounted near the on/off switch on the shifter, clicking up to upshift and down to downshift.

This some of video how drive with Auto-stick

Benefit of Auto-Stick

• Ability to manually select gears.
• Ability to start from 2nd or 3rd in inclement weather to improve traction.
• Allows downshifting while coming down steep inclines to maintain speed.
• Improved performance with quicker, more firm shifts.

Dodge Transmission System(TREMEC)

Dodge History

Dodge, formally the Dodge Division of Chrysler Group LLC is a brand of automobiles, minivans, and sport utility vehicles manufactured by Chrysler Group LLC, based in Auburn Hills, Michigan. Dodge vehicles presently include the lower-priced badge variants of Chrysler-badged vehicles as well as performance cars, though for much of its existence Dodge was Chrysler's mid-priced brand above Plymouth.

Founded as the Dodge Brothers Company by brothers Horace Elgin Dodge and John Francis Dodge in 1900, Dodge was originally a supplier of parts and assemblies for Detroit based automakers and began building complete automobiles in 1915, predating the founding of Chrysler Corporation. The Dodge brothers died suddenly in 1920 and the company was sold to Dillon, Read & Co. in 1925 before being sold to Chrysler in 1928. 

Dodge vehicles mainly consisted of trucks and full sized passenger cars through the 1970s, though it did make some inroads into the compact car market during this time. The 1973 oil crisis and its subsequent impact on the American automobile industry led Chrysler to develop the K platform of compact to midsize cars for the 1981 model year. The K platform and its derivatives are credited with reviving Chrysler's business in the 1980s; one such derivative became the Dodge Caravan. The Dodge brand has withstood the multiple ownership changes at Chrysler from 1998–2009, including its short-lived merger with Daimler-Benz AG from 1998- 2007, its subsequent sale to Cerberus Capital Management, its 2009 bailout by the United States government, and its subsequent Chapter 11 bankruptcy and acquisition by Fiat.

In 2011, Dodge, Ram, and Dodge's Viper were separated. Dodge said that the Dodge Viper will now be a SRT product and Ram will be a manufacturer.

TREMEC - Transmission Technologies Corporation is an American manufacturer of automobile transmissions, best known for their TREMEC line of manual transmissions

History of TREMEC

The manual transmission line of Borg Warner is now owned (since 1998) by Transmission Technologies Corporation (TTC), however, the design remains unchanged between the two transmission lines. Borg Warner transmissions, for the most part, use a single rail gear selector and carbon fiber lined steel synchro rings, where the TREMEC transmissions have a single rail that selects and moves three shift rods internally. 

These three rods have spring loaded detents that make the transmission feel notchy during shifting. Instead of carbon lined steel synchro rings, the TREMEC TKO line is built with solid bronze synchros with no linings. It is for these reasons that theTREMEC TKO does not like to shift well above ~6,000rpms unless modified. Carbon fiber rings are now available as well as several other modifications to improve shifting and durability.

Transmission Technologies Corporation is an American manufacturer of automobile transmissions, best known for their TREMEC line of manual transmissions. The company has a sales and engineering office in Plymouth, Michigan, and production facilities in Querétaro, Querétaro Mexico, Loppem, Zedelgem Belgium, Taluka - Khed, Pune India and Knoxville, Tennessee.

Some of the most famous TREMEC products were originally designed by Borg-Warner, including the widely-used T-56.Now currently use in latest dodge challenger

14 Corvette Stingray Get Better Fuel Economy

General Motors said the 2014 Chevrolet Corvette Stingray will get 29 m.p.g. on the highway and 17 m.p.g. in the city. The numbers are for the coupe version of the redesigned sports car when it's paired with a seven speed TREMEC TR 6070 manual transmission. The performance compares with 26 m.p.g. on the highway and 16 m.p.g in the city for the 2013 'Vette. A key competitor, the Porsche 911 Carrera S, gets 27 m.p.g. on the highway and 19 m.p.g. in the city.

GM engineers integrated several new fuel-saving technologies into the seventh generation Corvette to get better fuel economy. For example, the Corvette's eight cylinder engine can flip into four cylinder mode when the extra power isn't necessary. That helps save gasoline.

"The Corvette Stingray establishes the benchmark for modern performance cars by using 

technologies to deliver more performance and more miles per gallon," Corvette executive

chief engineer Tadge Juechter said in a statement. "We expect more and more performance 

cars will follow Corvette's example."

The coupel version of the Stingray, first revealed in January in Detroit, will be released in the fall. The convertible version will hit showrooms toward the end of the year.

Dodge Transmission

The OM3GA

Sun Coast calls this transmission package the OM3GA. It's a Dodge 47RE/48RE-based four-speed automatic designed to handle obscene amounts of horsepower and torque. It can be tailored to a variety of applications, including Ford, Dodge, and Chevy diesel trucks. This transmission was developed through the years as Cummins racers and hot-street-truck owners advanced their engines' horsepower levels.

Strength Training 

In the beginning, Cummins-powered Dodge trucks wiped out torque converters. Then the weak link moved to the input shafts. That led shops like Sun Coast to develop better converters and input shafts machined from billets of high-strength steel. These "billet shafts," as they are often called, still weren't always strong enough. The Sun Coast OM3GA fixed this problem with the introduction of a larger-diameter input shaft.

Increasing the diameter of the input shaft meant custom pump gears had to be made, along with a custom stator support, stator, and torque converter. The intermediate and output shafts have also been upgraded with billet shafts machined from 300M alloy.

OM3GA transmission installed in the J&H Performance Ramcharger.

A)   Short output shaft

B)    Mag – Hytec pan for additional cooling

C)    Universal TH350 crossmember for engine swaps

D)   Flexplate speed sensor that sends out a V-8 tachometer signal to run a variety of electronics.

Power Application
Unfortunately for mega-horsepower diesel owners, the carnage didn't end there. Bands would be destroyed, clutches would slip, and drums would explode, so the OM3GA transmission uses a revised clutch count and a rigid Second gear band (with more apply area), as well as a billet drum and steel planetary gears. The transmission has an increased-pressure Second gear servo, which meant the strut, anchor, and apply levers all had to be custom-made by Sun Coast.

DSG VOLKSWAGEN

DSG is a groundbreaking 'two-in-one' concept. Available in 6-speed and 7-speed versions, it's totally unlike a conventional automatic transmission. Twin electronically controlled shafts manage gear selection, always anticipating your next shift.

The technology

Two independent gearbox units make up the DSG. With dual-clutch technology - two clutches in a common housing - both gearboxes are connected under load to the engine in turn, depending on the current gear, via two drive shafts. Clutch 1 serves the first gearbox unit with 1st, 3rd, 5th 7th and reverse gear and clutch 2 the second gearbox unit with 2nd, 4th and 6th gear. An output shaft that applies the torque to the driven wheels via the differential gear is assigned to each gearbox unit.

Thanks to the dual-clutch design the DSG is more efficient than conventional automatic transmission. This efficiency, together with its low weight and intelligent control, means that DSG can achieve the same, and in some instances better, fuel consumption, than a manual gearbox or even lower, depending on the style of driving.

Mechatronics - electronics and mechanics in one unit

Clutches and gearbox units are operated hydraulically by the gearbox mechatronics (a combination of mechanics and electronics) housed in the DSG. The electronic transmission control unit, sensors and hydraulic control unit form one compact unit.

The control unit does the thinking for you, using information such as engine speed, road speed, accelerator position and driving mode to select the optimum gear and to determine the ideal shift point. The hydraulic control unit then implements the shift commands in a sequence of precisely co-ordinated actions.

Split-second gear changes

When one gear is engaged, another gear is always preselected. Within four hundredths of a second after the system detects a gear change it opens one clutch and closes the other. The mechatronics unit ensures that this takes place fast and to a level of accuracy that would not be possible in a manual transmission. The change of gear is imperceptible to the driver who is merely conscious of the uninterrupted power.

Volkswagen,Toyota & Dodge Transmission

Groups in this blogger will describe several types of car brands such as Volkswagen, Toyota n dodge. we will describe the transmission of each of these cars. hope you are all interesting to see. we will provide a link to allow you to find the source address. Thanks

The Introduction.

According to Merriam-Webster, transmission as an assembly of parts including the speed-changing gears and the propeller shaft by which the power is transmitted from an engine to axles then drive wheels. Basically transmission refers to the gearbox that uses gears and gear trains to provide speed ratios and torque conversions from a rotating power source to drive shaft. Transmission also the main part of powertrain after engine.

Location of the transmission in automobile

The most common use is in motor vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is unsuitable for starting, stopping, and slower travel. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and anywhere rotational speed and torque must be adapted.

Habitually, a transmission has multiple gear ratios (or simply "gears"), with the ability to switch between them as speed varies. This switching may be done manually (by the operator), or automatically. Directional (forward and reverse) control may also be provided.

In automotive industry, the transmission generally is connected to the engine crankshaft via a flywheel. The output of the transmission is transmitted via drive shaft to one or more differentials, which in turn, drive the wheels. While a differential may also provide gear reduction, its main purpose is to allow the wheels at either end of an axle to rotate at different speeds (essential to avoid wheel slippage on turns) as it changes the direction of rotation. The transmission can be manual and automatic system which will be elaborated further in our research for the transmission.
