Sonnax Pump Seal Ring Kit - Ford 5R55S Transmission

Sonnax Pump Seal Ring Kit for the Ford 5R55S automatic transmission. The oil pump is the heart of any automatic transmission, generating the hydraulic pressure needed to apply clutches, control shifts, and lubricate all moving components.

This component is precision-machined to ensure correct clearances and pressure output. Worn pump components cause low line pressure, slipping, overheating, and eventual transmission failure. Always inspect and replace worn pump parts during rebuilds.
