Sonnax 46892-03 Oversized Solenoid Pressure Regulator Converter Relief Valve

The Sonnax 46892-03 oversized solenoid pressure regulator/converter relief valve is designed for Ford and Mazda 4F27E, FN4A-EL, FNR5, and FS5A-EL automatic transmissions. This precision-engineered valve restores hydraulic integrity in worn valve body bores to eliminate shift problems and torque converter clutch (TCC) malfunctions.

Key Features:

• Oversized design compensates for bore wear in solenoid pressure regulator and converter relief circuits
• Restores proper oil pressure regulation to control solenoids
• Eliminates TCC apply and release concerns caused by pressure loss
• Requires bore reconditioning with F-46892-TL3 tool kit and VB-FIX reaming fixture
• Fits either of two locations: solenoid pressure regulator bore or TCC relief bore

Addresses Common Transmission Problems:

• Harsh or soft shifts caused by erratic solenoid supply pressure
• Solenoid performance codes and wrong gear starts
• TCC apply issues and TCC diagnostic trouble codes
• Clutch failure due to improper pressure control
• Loss of lubrication oil and delayed engagement
