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.

For  Information!!!!
Land Cruiser - Model BJ Series First Truck Generation

The chassis of the Toyota Jeep BJ was based on the SB-type 1-ton truck (with an S-type 995cc engine) that was originally released in 1947. The Toyota Jeep BJ was completed in 1951, and first unveiled that same year at a public showing of Toyota vehicles.




Toyopet Corona and Toyota Model SH First Cars Generation


Improvement of Toyota Transmission time to time

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
