Solenoid Control:

The wiring harness and TCC solenoid valves are critical to controlling shift timing and locking engagement. These solenoid valves allow the transmission control module to adjust shift parameters to ensure smooth and efficient shifting

Improved Fuel Economy:

The TCC solenoid valve can lock the torque converter to achieve direct drive, reduce engine speed during cruising

Transmission Performance:

The proper operation of the internal wiring harness and TCC solenoid valves ensures smooth operation of the 4L61E transmission, reducing jerky shifts, erratic behavior or unresponsive gears

High-quality materials for durability

The internal wiring harness is made of high-quality materials with strong resistance to high temperatures and wear, and can withstand the harsh working environment inside the transmission

Each wiring harness undergoes rigorous process treatment to ensure long-term stable operation

Built-in locking TCC solenoid valve for improved shifting performance

It can accurately control the locking and unlocking operations of the transmission torque converter, ensuring a tight connection between the engine and the transmission, thereby reducing energy loss, improving fuel efficiency, and improving acceleration response

It helps improve the vehicle's driving performance and power output while providing smooth gear shifting

Precise matching ensures smooth gear shifting

Whether in daily driving or under load, it ensures smooth gear shifting and avoids gear shifting delays or failures caused by electrical problems
