The Coan Racing COA‑11123 “Pro Tree Competition” 28″ Transmission is a turnkey, race-ready Powerglide built to deliver instant-launch performance and uncompromising durability. Its standout feature is the Instant Reaction Pro Tree 5-brake with reverse lockout, allowing drivers to pre-engage the brake pack for lightning-fast, transbrake-style launches while eliminating reverse from engaging at the same time. At the heart of this transmission lies a heavy-duty steel clutch hub supporting a six-clutch pack, worked in concert with a 300M alloy shaft (with TH splines) to handle high torque loads without flex or failure.

Encased in a deep aluminum pan for increased fluid capacity and enhanced cooling, the COA‑11123 also features reinforced internals ready for the rigors of bracket or circle-track racing. Its 28″ long assembly bolts directly into Powerglide setups without modification, making it ideal for racers seeking a highly durable, performance-driven solution that delivers sharp engagement, reliable line-lock capability, and consistent performance under competitive race conditions.
