Choosing the right transmission is critical for maximizing the potential of a Ford or Chevy engine upgrade. Total Performance Australia provides expert guidance on matching high-performance transmissions to specific engine platforms. The best option depends on your power goals, vehicle application, and budget. This guide outlines the most reliable and popular transmission choices for Australian builders.

Understanding Transmission Compatibility

Top Chevy Transmission Choices

Matching Torque Converters to Your Build

A torque converter is a fluid coupling that transmits power from the engine to the transmission. The stall speed of the converter must match the engine's power band for optimal performance. A converter that stalls too low will cause the transmission to slip, while one that stalls too high will bog down the engine. For street cars, a 2,200 to 2,500 RPM stall speed is typical. For drag cars, stall speeds can exceed 3,500 RPM. Total Performance Australia offers a range of high-stall converters for both Ford and Chevy applications, ensuring you find the right match for your build.
