What feeds the transmission cooler and torque converter in an automatic transmission?

The gear pump is integral to the operation of an automatic transmission because it is responsible for circulating transmission fluid throughout the system. This fluid is essential for several functions, including lubricating the gears, facilitating hydraulic movements, and ensuring that the torque converter and transmission cooler receive an adequate supply of fluid.

In an automatic transmission, the gear pump draws fluid from the sump (the lower part of the transmission where the fluid collects) and pumps it under pressure to various components, including the torque converter and transmission cooler. The torque converter uses this fluid to transfer power from the engine to the transmission, while the transmission cooler helps regulate the temperature of the transmission fluid by dissipating heat generated during operation.

By supplying the necessary fluid to these critical components, the gear pump plays a crucial role in the overall performance and efficiency of an automatic transmission, ensuring smooth gear shifts and optimal operation.
