Spring Press. Regulator 200-220 PSI

The COAN Spring Press Regulator 200-220 PSI (COA22044) is a precision fluid pressure regulating component designed for transmission systems that demand reliable valve modulation and controlled pressure response. Built for serious transmission builders and restoration specialists, this compact regulator spring maintains strict pressure tolerances in high-performance and stock rebuild applications alike. Whether you're tuning a street cruiser or restoring a vintage muscle car, proper regulator spring selection is non-negotiable for transmission longevity and shift quality.

This regulator spring operates as a tension element within the transmission's pressure regulator valve assembly, controlling the opening point at which excess fluid bypasses to the pan and modulating line pressure throughout the gearbox. The 200–220 PSI rating indicates the spring's calibrated stiffness—engineered to balance firm shift engagement with smooth torque delivery. At 0.08 lbs and measuring 5 × 0.95 × 6.1 inches, its compact geometry fits standard regulator cavities while maintaining critical preload consistency. COAN's manufacturing standards ensure the spring resists fatigue and corrosion, preserving pressure regulation across thousands of heat cycles typical in street and strip duty.

Transmission rebuilders and performance enthusiasts rely on this component when replacing worn or damaged regulator springs that cause delayed shifts, slippage, or erratic pressure behavior. It fits most domestic automatic transmissions requiring a matching PSI range and cavity diameter—always verify your transmission's original specifications before ordering. Install this spring as part of a complete regulator valve overhaul to restore factory shift characteristics or fine-tune pressure for modified engine output. Proper installation ensures the regulator valve seats fully and maintains repeatable, predictable pressure response under all driving conditions.
