Product Details

The TCI Automotive 221301 is a high-performance transbrake solenoid designed specifically for TH350 transmissions in racing applications. This compact solenoid enables instant rear brake band engagement, allowing drivers to build boost or RPM at the starting line while keeping the vehicle stationary.

Key Features:

  • Ultra-compact design at only 1.025 inches long for easy installation in tight spaces
  • Conical face design handles higher forces than standard flat-faced solenoids
  • Precision wound coil maximizes copper content in available space for maximum force output
  • Stroke length of .180 to .200 inches for reliable engagement
  • Two-wire setup ensures proper electrical grounding for consistent performance
  • High-efficiency construction for rapid response and durability

This solenoid is engineered to withstand the demanding conditions of drag racing and high-performance street applications. The space-saving design makes it ideal for tight transmission installations where clearance is limited.
