Section 5: C-4 & C-6 Transmissions

Lightweight, Simple, and Sturdy 3-Speed Transmissions

The C-4 and C-6 three-speed automatic transmissions have a time-tested design of proven simplicity that makes them a favorite for off-road applications such as drag racing. Baumann Electronic Controls can provide most of the necessary components for anything from a stock rebuild to a full-race unit. We can provide items such as overhaul kits with stock or special exotic friction materials, "Trans-Brake" valve bodies, and even a wide ratio gear-set for the C-6 (utilizing the four pinion planet set from the E4OD transmission, which has a 2.71-1 first gear ratio). Contact us for more details when contemplating your next C-4 or C-6 project.
