The Coan Racing COA‑22823C‑AL Aluminum Pump Body is a precision-engineered unit tailored for performance-oriented TH400 transmissions. Crafted in the USA from high-strength aluminum and secured with an 8-bolt pattern, it includes coated internal gears to reduce wear and optimize hydraulic flow. Designed to be "lock-up or converter dump ready" with GM converter drive, this pump body offers builders flexibility for both torque converter lock-up and high-flow performance setups.

As a drop-in component, the COA‑22823C‑AL fits seamlessly into stock TH400 cases without any machining required. Its reduced internal volume design helps minimize hydraulic drag while preserving necessary pressure, making it ideal for drag, bracket, and spirited street builds. The combination of lightweight construction, durable coatings, and modern converter compatibility yields a technically advanced foundation for building efficient, race-capable transmissions.
