Product Details

The Sonnax 104740-45K is a high-quality replacement spring designed for torque converter clutch (TCC) regulator valve applications in automatic transmissions. This precision-engineered spring helps maintain proper hydraulic pressure regulation for smooth torque converter lockup operation.

Key Features:

  • Precision-manufactured to OE specifications for reliable performance
  • Restores proper TCC regulator valve pressure and function
  • Helps eliminate harsh converter engagement and slipping issues
  • Essential component for transmission rebuilds and valve body repairs

Very fast delivery on a high quality product.

Service was great. However, I first needed to change an order & found I had to cancel it and reorder correctly. I did this. However, the second order was also cancelled by the warehouse because they thought it was a duplicate. I reordered again! The battery was shipped this Monday & arrived Tuesday! So... other than the "safe" second cancellation, everything is 100% good! Battery arrived and I did a quick voltage test. 12.78 V ...

Quality of products (Marine grade cabinet hardware & hooks) was excellent and as expected. Delivery was quick. Everything came in two shipments. The first arrived faster then indicated, the second exactly as indicated. Smooth experience.
