Stator backing plate for Allison transmissions

The stator backing plate 6759855 serves as an internal component within the torque converter of an automatic transmission. Its primary function is to provide structural support and maintain the precise positioning of the stator, which is responsible for redirecting hydraulic fluid flow to facilitate torque multiplication. By ensuring the stator remains correctly aligned, this plate supports the efficient transfer of power from the engine to the drivetrain.

This component is engineered for specific Allison transmission models used in commercial vehicles, heavy-duty trucks, buses, and industrial machinery. It is designed to accommodate the internal operating environment of the torque converter, including fluid pressures and rotational forces. Proper installation of this plate is necessary to maintain the alignment of the stator assembly and the overall fluid dynamics within the converter housing.

In an automatic transmission, the stator acts as a reaction member that redirects fluid returning from the turbine to the pump, which allows the torque converter to multiply engine torque at lower speeds. The backing plate ensures that the stator remains stationary or rotates only as intended by the transmission design, preventing internal misalignment that could otherwise affect the efficiency of the torque multiplication process.
