Ram 1500 Automatic Transmission Oil Pumps

The oil pump is a part found exclusively in automatic transmissions. While manual gearboxes use oil only for lubricating purposes that can be achieved without a pump, the AT uses oil as a hydraulic liquid as well. Automatic transmission fluid actuates the valves that control pressure, select the correct gears ratios, and operate the pistons and servos for the bands and clutches to be engaged. What the pump does is providing the liquid with kinetic energy that actually allows that work to be done.

In your Ram 1500’s AT, the pump is represented by one external and one internal spur gear sitting on the transmission input shaft. When the shaft rotates, the gears come into action while moving the fluid. Thanks to its simplicity (say dependability) and evenness of the flow, such a scheme, with minor variations, is broadly used wherever the lubricant or hydraulic fluid pressure is needed. While the gears themselves are robust and rarely cause any troubles, the seals that make the system tight may leak – that’s a widespread problem. But don’t worry, as our Ram 1500 automatic transmission oil pumps & components collection provides you with a full range of high-quality replacements for your truck’s AT pump.
