"Soft Shift" Accumulator Assembly

"SOFT SHIFT" ACCUMULATOR ASSEMBLY, MOUNTS IN PLACE OF GOVERNOR COVER

(REQUIRES INTERNAL AND EXTERNAL PLUMBING)

The Coan Racing COA‑22050 "Soft Shift" Accumulator Assembly is an innovative hydraulic enhancement engineered to elevate shift quality and comfort in high-performance TH400 transmissions. Designed as a direct replacement for the factory governor cover, this billet aluminum assembly incorporates a precision-calibrated accumulator that smooths line pressure fluctuations during shifts, significantly reducing harsh engagement and improving drivability. Tailored for racers and performance enthusiasts, installation of the COA‑22050 requires plumbed connections both internally and externally, ensuring seamless integration.

Built with coarse-thread fittings and sealed surfaces for leak-proof operation, the COA‑22050 is an ideal upgrade during transmission builds. When installed, it offers a tangible refinement in shift feel, enabling firmer yet smoother transitions under load, particularly beneficial for bracket or street-strip applications where launch repeatability and drivetrain control are paramount.
