GM Torque Converter TH350C 2200 - 2800

The ACC Performance GM Torque Converter TH350C 2200–2800 RPM (part number 47402) is a lock-up torque converter engineered for high-performance transmission applications requiring precise stall speed control and efficient power transfer. This 10.750-inch bolt circle converter is designed for TH350C transmissions and delivers the engagement characteristics needed in street performance, off-road recovery, and specialized driving scenarios where consistent torque multiplication and controlled slip characteristics are critical to driveline integrity and vehicle response.

Rated for a 2200–2800 RPM stall range, this converter provides moderate slip during launch, balancing acceleration feel with transmission durability. The Night Stalker lock-up design reduces slippage once the vehicle reaches cruising speed, minimizing heat generation and improving fuel efficiency compared to non-locking units. The 39.39-pound assembly (13.3 x 8.1 x 13.45 inches) integrates seamlessly with standard TH350C installations, maintaining OEM mounting dimensions while delivering upgraded performance characteristics. Lock-up torque converters like this one are essential for vehicles that demand responsive power delivery without sacrificing longevity in high-demand applications.

This converter suits users operating vintage performance vehicles, off-road platforms with TH350C transmissions, or specialized builds where transmission control and thermal management matter. The 2200–2800 RPM stall window targets mid-range engine packages that benefit from moderate engagement slip without excessive line pressure or transmission stress. Operators and enthusiasts building or rebuilding high-performance drivetrains rely on properly matched converters to prevent premature transmission wear, maintain predictable shift quality, and protect against heat-related failures under sustained demand.

Torque converter selection is critical to transmission longevity and driveline compatibility. A stall speed that is too low results in excessive slippage and heat; too high creates harsh engagement and increases shift shock. The 2200–2800 RPM range on this ACC Performance unit targets applications where thermal load and engagement response must align with engine output and vehicle weight. The lock-up feature reduces parasitic losses during steady-state driving, extending transmission fluid life and improving overall system efficiency.
