Extreme Duty Pump Assembly w/ Heat Treated Stator Support - 200-220 PSI

EXTREME DUTY PUMP ASSEMBLY W/ HEAT TREATED STATOR SUPPORT (200-220 PSI)

The Coan Racing COA‑22822 Extreme Duty Pump Assembly with Heat-Treated Stator Support (200–220 PSI) is a robust, high-pressure transmission pump engineered for the most demanding Turbo Hydramatic 400 builds. This assembly delivers an elevated line pressure range of approximately 200 to 220 PSI, significantly exceeding the standard race-prepped pump’s 180 PSI output. This increased pressure ensures firmer shifts, improved clutch lockup, and greater hydraulic consistency, critical benefits during aggressive launches, repeated launches, and sustained high-RPM driving scenarios typical in drag racing or bracket competition.

Constructed with a reinforced, heat-treated stator support, the COA‑22822 is built to resist fatigue under elevated load cycles. Its durable design helps sustain consistent fluid delivery even under extreme conditions, reducing the risk of pressure loss and clutch slippage over time. Engineered as a direct-fit replacement, this pump installs seamlessly into stock TH400 cases without machining, providing a reliable upgrade path for performance-minded builders aiming to fortify their transmission’s hydraulic core.

Ideal for racers and street/strip enthusiasts alike, the COA‑22822 stands as a cornerstone component in any high-performance transmission rebuild, delivering consistent, race-level line pressure and dependable operation during the most extreme driving conditions.
