Case Bushing - Rear

CASE BUSHING (REAR)

The Coan Racing COA‑22512 Case Bushing (Rear) is a precision-engineered component designed to reinforce the rear section of automatic transmission cases during high-stress, high-performance applications. Crafted to exacting specifications in the USA, this bushing slips into the rear housing to maintain correct shaft alignment, reduce end-play, and preserve hydraulic integrity even under intense torque and temperature conditions common in drag racing and heavy-duty street use. Its durable material construction offers superior wear resistance compared to worn OEM bushings, helping to extend the service life of your transmission by maintaining consistent internal clearances.

Ideal for rebuilds or performance upgrades on TH400 transmissions, the COA‑22512 installs as a direct replacement without case modifications. By providing enhanced radial and rear-end support, this rear case bushing contributes to smoother driveline operation, improved power transfer, and reliable long-term performance in demanding driving environments.
