Sonnax 76948-04K Bypass Clutch Control Sleeve and Plunger Valve Kit

The Sonnax 76948-04K bypass clutch control plunger valve kit restores hydraulic integrity in Ford AODE, 4R70W, 4R70E, 4R75W, and 4R75E automatic transmissions. This direct replacement kit is designed to address common torque converter clutch (TCC) problems that plague these transmission models.

Resolves Common Transmission Issues:

• Delayed lockup, shudder, no lockup, and converter codes (including Code 628)
• TCC slip or no apply conditions caused by severe leakage
• Slow bypass valve reaction from MCC/TCC solenoid oil
• Regulated converter charge oil leaking to exhaust from excessive plunger valve wear

Key Features:

• Single .030" orifice, much smaller than OE size, allows bypass clutch control valve to properly stroke to TCC apply position
• Smaller orifice allows TCC oil to stroke the bypass valve more quickly while improved plunger and sleeve replace worn components
• Eliminates the need to modify the plunger feed hole in the separator plate
• Complete kit includes both sleeve and plunger valve for comprehensive repair

This Sonnax kit provides a proven solution for transmission technicians dealing with Ford automatic transmission torque converter clutch problems. The precision-engineered components restore proper oil flow control and eliminate common TCC-related driveability concerns.
