TCC Modulator sleevekit 4R44E, 5R55R

• Sleeve 
• Spacer 
• Solenoid Regulator Valve Spring 

Constant oscillation of the torque converter clutch (TCC) modulator valve creates wear in the valve body bore, which can allow converter solenoid oil to exhaust. This prevents the TCC modulator valve from stroking fully to the apply position, which can create a no lockup complaint and/or set a 1741 code. Wear at the other end of the valve can prevent TCC release, resulting in cover dragging and stall on forward engagement.

• Specially toleranced alloy aluminum sleeve is significantly more wear-resistant than the cast aluminum valve body.
• Alloy aluminum sleeve provides more contact surface with the valve for increased stability and durability.
• Kit includes a replacement solenoid regulator valve spring, which is often damaged during valvebody disassembly.
• The tool kit also works with the 37947-05K pressure regulator valve sleeve kit.

TCC Springkit 4R44E, 5R55E, 4R55E

• Outer Springs (5) White
• Inner Springs (5) Plain

 The 2.3L TCC regulator valve has a lower spring rate and lower apply pressure than the 4.0L. If the incorrect core is installed or the springs have been damaged, the TCC apply pressure is reduced and slippage occurs. The springs in the Sonnax kit 37947-46K have been designed to match the 4.0L calibration. The kit can be used to replace weak, broken or lost springs in 4.0L applications or to convert a 2.3L valve body core for use in a 4.0L application.

Pressure Regulator Sleevekit 4R44E,5R55E

• Sleeve 
• Retaining Clip 
• Solenoid Regulator Valve Spring 

 Constant oscillation of the pressure regulator valve can cause excessive wear at the balance line end of the bore, allowing balance line pressure to exhaust and preventing the pressure regulator valve from stroking to the lower line pressure position. Severe wear prevents line from entering the converter apply circuit, which will also restrict valuable cooler flow.

• Specially toleranced alloy aluminum sleeve is significantly more wear-resistant than the cast -aluminum valve body, and provides more contact surface with the valve for increased stability and durability.
• Kit includes a replacement solenoid regulator valve spring, which is often damaged during valve body disassembly.
• The tool kit 37947-TL5 also works for the 37947-07K TCC Modulator Sleeve Kit.
