Description

The Coan Racing COA‑22050 "Soft Shift" Accumulator Assembly is a billet aluminum hydraulic enhancement that replaces the factory governor cover in TH400 transmissions. It incorporates a precision-calibrated accumulator to smooth line pressure fluctuations during shifts, reducing harsh engagement and improving drivability. It is designed for seamless integration during transmission builds and offers firmer yet smoother transitions under load, beneficial for bracket or street-strip applications.
