Our capabilities include Stamping, Machining, Welding, Plastic Injection Molding, Rubber Molding, Broaching products, Electronic Parts and in-house tooling and design services.

Our product line covers most soft parts of automatic transmission, specializing in filters, bands, plates, clutches, one way clutch (sprag), solenoid, harness, sensor and customized product to achieve customers’ specific need.

OEM (Original Equipment Manufacturer)
Linesoon offer not only manufacture original part but also design service.

Automatic Transmission Filter / Filter Kit
The filtration capability is usually an important index for filters thus the quality of filtration medium is critical. To ensure the filtrating quality, we use the filtration paper as the same as used in OE for all our filters.
In the pursuit of the best quality filters, we further implement various tests to verify and ensure the filters with high performance and long life use.

Electronic Part
As electronic auto transmission has become the trend in industry, the usage of electronic parts in transmissions is increasing. To provide the best quality parts, stability, accuracy, and toughness are especially concerned in our electronic product development. We are not only to make OE compatible parts but always has the faith to beyond OE.
Our product line includes HARNESS, SOLENOID, PSM, CIRCUIT BOARD, PRESSURE SENSOR, and SPEED SENSOR, All the products are under 100% inspection before delivery to guarantee the best quality.

Band
More than 30 years experience of making band provides us sophisticated technologies & knowledge. It has led us to be the expert of making bands in the market. We supply various types of band such as double wrap, flex, and brake band for both OE and AM.
For the request of top quality, we select qualified liners carefully as the friction material and also implement free wheeling test and friction test to verify the functional and dimensional fitness to ensure a lower drag and a longer life use in our bands.

One Way Clutch
One Way Clutch is a functional part mounting between the inner race and outer race to transmit the torque in one rotating direction or rotate freely to shut off the torque in the reverse direction.
Thus torque tests such as rollover test, stroking durability test, and free wheeling test are implemented in our one way clutch to ensure well function and quality.

Steel / Friction Plate
The qualified liner is selected as the friction material for the friction plates and the destructive test is always implemented in our production run to ensure well-bonded effect. Also gages are applied to examine the plate in flatness and parallelism.
