SunCoast 68RFE Transmission Rebuild Kit 07.5-18 | 19-24 Ram 6.7L Cummins

The SunCoast Category 68RFE transmission rebuild kits are designed with the goal of solving the issues with the 68RFE transmission in a systematic way. SunCoast carefully considers each deficiency and need before developing these kits. These kits offer you the same recipes that SunCoast uses in their facility when building these units. They strive to provide the most complete series of 68RFE rebuild kits available on the market today, with proven combinations for a successful build. THE GUARDIAN KIT: Sometimes when a transmission breaks, the most cost-efficient means of repair is usually a rebuild. SunCoast's Guardian kit contains everything you need to get your 2007.5-2018 or 2019-2024 Ram back on the road after a failure. Including SunCoast's improved Guardian torque converter and billet inner parts, not only will you rebuild, you'll rebuild stronger. THE SMART TECH DRUM (CATEGORY 1 ONLY): The new billet clutch housing holds a physically taller clutch pack, allowing the overdrive apply clutch area to increase by 16%. In addition to the increased apply surface area, the thicker clutches and steels increase clutch steel mass by 28%, drastically improving heat dissipation. The new 68RFE overdrive clutch drum also comes with a top bolt-on plate to help eliminate clutch pack flexing and distortion that contribute to premature failure. THE V2 BILLET DRUM ASSEMBLY (CATEGORY 2, 3 & 4): The V2 68RFE Billet drum is the most revolutionary advancement for the 68RFE. SunCoast invested extensive research and development into this drum, which can handle over 1,000 horsepower. It addresses overdrive circuit issues while eliminating the common 68RFE squawk. With a 24% increase in hydraulic clamping force, it significantly improves apply time and reduces slip engagement. Additional enhancements include improved overdrive friction elements, a quad-ring O-ring for reliable compression at high RPMs, increased wall thickness for better rigidity, and a redesigned lip seal for enhanced sealing. This fully assembled, drop-in replacement requires no factory parts, ensuring easy installation and superior reliability. THE 2C PISTON (ALL KITS): SunCoast replaced the factory piston with an improved billet piece that accommodates an additional clutch, further increasing the surface apply area. ZERO CAVITATION FILTER KIT (CATEGORY 1, 2, 3 & 4): This bottom feeder filter kit uses a Torqueflite filter to prevent pump cavitation and allow higher fluid volume. It improves fluid flow under high line pressure and requires a deep aluminum SunCoast pan or a specific OE pan, both included in the kit. THE HIGH-PRESSURE TUNELESS REPROGRAMMING KIT (CATEGORY 1, 2, 3 & 4): Designed for increased horsepower and torque, this kit delivers a re-calibrated pressure curve for improved clutch and TCC holding capacity. It features a 30% increase in line pressure, a converter clutch bypass to prevent ballooning, and additional components for enhanced reliability and performance. THE PISTON REPLACEMENT (CATEGORY 1, 2, 3 & 4): The Sonnax Accumulator Piston Kit prevents piston-to-bore scuffing and improves durability with its billet aluminum construction and optimized design. THE DEEP PAN (CATEGORY 2, 3 & 4): The SunCoast deep aluminum pan adds 4 quarts of transmission fluid capacity, improving cooling and heat dissipation. It features a flush-mounted drain port for easy fluid replacement and is compatible with the SunCoast Zero Cavitation filter kit. THE TORQUE CONVERTER (ALL KITS): The SunCoast Torque Converter is engineered for reliability, with features like furnace-brazed fins, hardened turbine splines, carbon-graphitic clutches, and a billet apply piston for precise and consistent lock-up. THE FLEX PLATE (CATEGORY 3 & 4): The SunCoast Billet Flex Plate is CNC-machined for strength and designed to flex while preventing cracking. It meets SFI specification 29.3 requirements for safety and durability in high-performance applications. THE INPUT SHAFT (CATEGORY 3 & 4): This drop-in replacement input shaft is made from billet 300 Maraging steel alloy for exceptional strength, designed for high power and torque applications. THE BILLET VALVE BODY PLATE (CATEGORY 3 & 4): Made from billet aluminum, this plate eliminates warpage and hydraulic cross leaks, addressing common issues like clutch failure and valve body wear. THE INPUT CLUTCH HUB (CATEGORY 4 ONLY): Manufactured from 4140 heat-treated billet steel, the input clutch hub provides increased strength at the input shaft spline area, ensuring reliability. THE SONNAX HD OVERDRIVE CLUTCH HUB (CATEGORY 4 ONLY): This upgraded clutch hub and shaft are cryogenically treated and shot-peened to reduce crack formation, providing exceptional reliability under high load.
