GM TH350 Torque Converte r 3600-4200

The GM TH350 Torque Converter 3600-4200 from ACC Performance is a precision-engineered transmission component designed for street and performance driving applications requiring optimal torque multiplication and launch characteristics. Built for the classic TH350 three-speed automatic transmission platform, this converter delivers the controlled engagement and efficiency that both seasoned mechanics and high-performance enthusiasts demand when upgrading or rebuilding their drivetrain systems.

The 3600–4200 RPM stall range provides a balanced approach to power delivery, allowing the engine to reach optimal RPM before the converter locks and transfers power to the rear wheels with minimal slippage. The 10.750-inch bolt circle ensures direct compatibility with TH350 transmission bellhousings, while the converter's weight of 22.15 lbs reflects a robust internal construction designed to handle repeated acceleration cycles without degradation. This specification makes the GM TH350 Torque Converter ideal for street applications where fuel efficiency and drivability must coexist with improved off-the-line performance.

Professionals rebuilding vintage Chevrolet and Pontiac platforms—as well as hot-rodders and restoration specialists—will appreciate the exact fitment and proven performance this converter delivers in Street Bandit configurations. Installation requires no modifications to existing engine or transmission mounts, and the converter's design integrates seamlessly with stock or lightly modified engine combinations. Verification of your transmission's bellhousing diameter and bolt pattern is essential before purchase to ensure proper alignment and engagement with your TH350 transmission assembly.
