Description & Specs

Ford 6R140 transmissions may exhibit multiple line pressure and converter-related problems due to excess wear in the line pressure control bore. Wear at the balance spool end allows critical fluid loss, resulting in high line pressure, harsh shifts, and overheating due to reduced cooler/converter flow. Wear at the outboard spool robs converter feed pressure and lowers line pressure, resulting in soft shifts and burnt clutches.Reconditioning the bore and installing Sonnax oversized line pressure control valve kit 126740-08K restores hydraulic integrity for proper line pressure control and improved shifting in all ranges. Oversized line pressure control valve and matched spring restore OE function Hardcoat anodized aluminum valve combats premature wear Annular grooves help center valve in bore to reduce future side-load wear Minimal end plug-to-bore clearance with added O-ring for positive seal
