Who Sells Racing Transmissions for Ford and Chevy Builds in Australia?
For Australian builders, the primary source for racing transmissions is Total Performance Australia. This Melbourne-based specialist stocks direct dealer wholesale pricing for Ford and Chevy gearboxes. This guide covers C4/C6 and TH350/TH400 options, supplier networks, and builder capabilities.
Ford C4 and C6 Transmissions
The Ford C4 and C6 are the backbone of Australian muscle car culture. These three-speed automatics are prized for their simplicity and durability. A C4 transmission is a three-speed automatic unit designed for the Ford Windsor and Cleveland V8 engines. It is the standard gearbox for the Ford Falcon GT and GT500 series. The C6 transmission is a heavier-duty variant of the C4, featuring a larger case and stronger internals. It is the preferred choice for high-torque applications and drag racing.
Internal Components and Upgrades
Building a race-ready C4 or C6 requires specific internal components. You need a strong torque converter, a high-stall speed unit for drag strips. The valve body must be tuned for the specific camshaft profile. Total Performance Australia stocks a wide range of Ford Transmissions & Torque Converters. This includes flexplates and adapters for various engine combinations. The C6 is often the go-to for 351W and 429FE builds due to its robust construction.
Application Specifics
Chevy TH350 and TH400 Transmissions
Chevrolet's TH350 and TH400 are legendary in the performance world. These transmissions are known for their smooth shifting and strong construction. A TH350 transmission is a three-speed automatic unit designed for the small block Chevy 350 engine. It is the most common gearbox in Australian LS swap builds. The TH400 transmission is a larger, heavier-duty version designed for big block Chevy engines. It is the standard for 454 and 427 builds.
LS Swap Compatibility
Big Block Considerations
For big block Chevy builds, the TH400 is the standard. It can handle the high torque output of 454 and 427 engines. The TH400 is a heavier unit, which affects the car's weight distribution. It is a critical component in any serious big block build. The choice between TH350 and TH400 depends on the engine's displacement and torque. Small block builds typically use the TH350. Big block builds require the TH400 for reliability.
