LOW VOLUME ALUMINUM PUMP BODY (ONLY) W/ COATED GEARS

• 8-bolt

The Coan Racing COA‑22823B‑AL Low‑Volume Aluminum Pump Body is a precision-engineered component tailored for transmission builders focusing on TH400 platforms, this pump body features a lightweight aluminum construction that reduces parasitic drag compared to OEM cast-iron units while maintaining high structural integrity under demanding driving conditions. Its 8‑bolt design ensures sturdy mounting, while the inclusion of specially coated internal gears enhances wear resistance, promotes smoother fluid flow, and improves long-term durability under high-stress, high-temperature operation. 

Designed as a direct-fit component, the COA‑22823B‑AL seamlessly integrates into stock transmissions without requiring case modifications. Ideal for race-prepped, bracket-race, or aggressive street builds seeking to optimize hydraulic efficiency, this low-volume pump body supports lighter fluid draw and quicker transmission response. It’s an excellent foundation for builders aiming to reduce internal drag and improve performance while preserving compatibility with existing bolt-on components and OEM configurations.
