Designed for durability and reliability, this transmission delivers smooth, responsive shifts and enhanced torque capacity to handle demanding conditions.

A billet accumulator piston eliminates the common failure of the factory plastic piston, restoring hydraulic integrity and reliability. To prevent second-gear band burn-up, SunCoast replaces the factory cast servo with a larger billet servo for stronger apply pressure and better release. The pro-series carbon fiber band, billet band anchor, and billet band strut enhance friction performance and strength. With a custom-calibrated valve body, increased line pressure, and a new SunCoast-proprietary separator plate, this transmission is optimized for heavy loads, aggressive tuning, and everyday reliability.\u003c\/p\u003e\n\u003ch4\u003eEliminate Slip and Maximize Efficiency with SunCoast’s Converter\u003c\/h4\u003e\n\u003cp\u003eThe SunCoast billet triple-disc torque converter is designed to eliminate slip, reduce heat, and improve power transfer over the stock unit.
