The Sun Coast Category 5 48RE transmission is the ultimate upgrade for those seeking significant improvements over the stock unit, designed to handle the demands of high torque and extreme towing or hauling. This transmission includes a comprehensive array of billet components, engineered to enhance performance, safety, and durability.

Key features include the billet triple disc torque converter with a 27-spline design, lined with carbon graphite clutch material and equipped with a precision CNC-machined forged billet apply piston. This upgrade provides a consistent and reliable power transfer, essential for high-performance applications. The billet 27-spline input shaft, made from 300 maraging steel, is heat-treated and stress-relieved to handle increased torque and stress loads. This shaft is complemented by an exclusive 27-spline stator support, also included in this transmission.

The transmission also features a billet 29-spline output shaft, precision-machined from 300M material, and heat-treated for exceptional torsional strength. This output shaft has been rigorously tested to withstand in excess of 1,400 ft/lbs of torque, making it suitable for the most demanding applications.

Additionally, the transmission is equipped with a billet forward drum and direct drum, providing enhanced strength and reducing deflection during operation. The Ultimate Weapon Billet Direct Drum, made from 4140 billet steel, offers superior safety and performance, especially critical at high RPMs where the drum is subjected to extreme forces. This drum also features an extended snap ring groove, allowing for the inclusion of more clutches and improving shift times.

The transmission includes a billet SFI certified flexplate, CNC-machined from a single forging, designed to exceed 29.3 SFI certification standards. This flexplate ensures minimal torsional flex and provides reliable performance under high power conditions.

For band actuation, this transmission utilizes a custom billet carbon fiber band, CNC-machined from billet steel, offering unparalleled performance. The billet intermediate servo, billet band anchor, and billet band strut address common shortcomings of the 48RE transmission, ensuring reliable and precise band actuation.

The billet forward and direct pistons, included with this transmission, replace the factory cast pieces, offering higher clamping forces and eliminating potential cross leaks within the drum. These upgrades result in a much more direct shift feel and improved overall transmission performance.

This transmission also includes a billet rear clutch retaining hub, made from 4140 heat-treated billet steel, addressing the weaknesses of the factory cast piece. This billet hub is designed to withstand high torsional fatigue situations, making it ideal for heavy-duty towing and commercial use.

The billet intermediate shaft, precision-machined from 300 Maraging steel, is designed for extreme off-road service and high-performance applications. The shaft is heat-treated for superior surface toughness and durability, with large blended radius spline machining to reduce common fractures associated with the OEM design.

Lastly, the billet output shaft, also included in this transmission, is engineered for higher horsepower and torque engines, providing exceptional torsional strength and precision.
