Over a year ago, our company, Ltd. defined its mission in the high performance automotive aftermarket with the acquisition of our company Performance Products. Our focus has been to expand and position ourselves as the industry leader in manufacturing high performance, specialized torque converters, automatic transmissions, and heavy-duty components. While the our company name is synonymous as a leader in racing or street performance, customers who desire special performance or economy oriented products can get similar results and satisfaction. A large part of our product line is dedicated to the streetrodder and end user who needs better performance whether it be economy, street use, foreign car use, off-road performance and much, much, more. Dedicated to providing our customers with the very best products, our company Performance toyotaautoparts Products continues to improve with "state of the art" equipment, hydraulic valve body testers, electronic valve bodies, dynamometers, robotic welders, electronic balancers and planetary manufacturing capabilities. As we enter the new millennium, our company Performance Products offers an innovative product line, and assures our customers of top of the line engineering standards and quality by using an entire production line of CNC equipment dedicated to producing the same specifications every time. Custom fabrication is available as well.

An automatic transmission requires a coupling between the engine’s crankshaft and the transmission’s input shaft. And while in a few special applications, like in oval track and marine setups, a direct coupler is used, the majority of all automatic transmission installations utilize a torque converter. In addition to functioning as a fluid coupling between the engine and transmission, a converter provides an additional benefit through multiplying the torque input, much like a gear set. There are a number of parts in a torque converter, three of which give it the basic operating characteristics… the pump, the turbine, and the stator. The pump has rows of curved toyotaautoparts vanes arranged inside a bowl-shaped casing. The turbine is the part that actually is responsible for turning the transmission-input shaft. Like two electric fans facing each other, one with the power on, and one with the power off working in unison causing the internal rotation. When a car is just beginning to move from a dead stop the pump will be rotating much faster than the turbine. Therefore the oil will be toyotaautoparts working against the turbine blades with a great deal of force. In the process of passing through the stator, the direction of the flow of the ATF is reversed. If this fluid were simply allowed to re-enter the pump, it would have a tendency to work against the pump’s direction of rotation. Instead the fluid is forced though the stator section of the converter which uses the special shape to reverse the direction of flow.

Transmission Overview OEM automatic transmissions are more closely matched to their use through valves and varying clutch capacity, with the intent to provide an inoffensive "softer" shift. This soft shift is achieved through a certain degree of "slippage", which can lead to overheating, a measurable loss of efficiency and a premature transmission failure. Vehicles of later model have a torque converter that engages in high gear, and in some cases second and third gear, creating lower RPM''s suited to emission control. To create a transmission that is better suited to meet the needs of our customer, our company offers everything from completely rebuilt transmissions to various component kits. Our valve body and reprogramming kits offer more positive shifting, performance oriented automatic shift points and full manual control when desired.
