Interchange Part Number: 124740-12KManufacturer Part Number: 124740-12KBrand: SonnaxManufacturer Warranty: No Warranty 6F50, 6F55, 6T70 (Gen. 1), 6T75 (Gen. 1) Oversized Pressure Regulator Valve KitPart No. 124740-12K Tooling: F-124740-TL12 VB-FIX Ford 6F50, 6F55 and first generation GM 6T70, 6T75 transmissions may exhibit multiple line pressure and converter-related problems due to excess wear in the main pressure regulator bore. Wear at the balance spool end allows critical fluid loss, resulting in excess 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. After reconditioning the bore, installing Sonnax oversized pressure regulator valve kit 124740-12K will restore hydraulic integrity for proper line pressure control in all ranges. Oversized press
