SunCoast Category 3 48RE 600HP Transmission With Torque Converter 03-04 Dodge Ram 5.9L Cummins
If your 03-04 Ram has either succumbed to the common burnt 2nd gear, the bands have given out, or you're simply wanting to have a sturdy reliable transmission for your workhorse or sport truck, the SunCoast 48RE Category 3 transmission a perfect upgrade for towing, hauling or slightly modified trucks with a rating of 600 horsepower. There are several key components in this transmission that are upgraded to not only improve performance, but also restore hydraulic integrity leading to increased reliability and longevity.
For starters, the factory accumulator piston is plastic, which deteriorates over time causing it to crack or simply break. It's also not uncommon to see this accumulator piston cross-leak within the bore. To combat this, SunCoast engineered a billet four-ring sealing piston versus the factory two-ring. It is standard in all of SunCoast's units to replace this factory piston with their billet piston to not only restore hydraulic integrity, but to improve reliability as well.
To alleviate issues with the factory intermediate band circuit, SunCoast addressed several facets of the too common second gear band burnups on the 48RE. First, the servo that applies the intermediate band itself has been replaced with a larger billet servo that supplies more pressure and improved release. This servo also is improved to a four-ring servo, versus the factory two-ring, with the primary sealing ring being square-cut teflon and the secondary being an o-ring.
Additional upgrades to the band circuit include the addition of a billet band anchor, billet band strut, and a billet apply lever. The band is further upgraded to a pro-series, carbon graphite band to improve friction performance. The valve body and pump are also recalibrated and the separator plate is replaced with a new laser-cut, SunCoast proprietary plate. This allows not only optimal line pressure, but also increased volume. Each one of these valve bodies and pumps is custom built for the customer's individual needs, whether it be towing, street performance or track.
SunCoast also installs a billet one piece input shaft. This shaft is made from 300 maraging steel and is then heat treated and stress relieved to handle the additional demands of higher torque and stress loads, from a multi-disc torque converter. This shaft is precision ground to make it a true drop-in replacement.
Suncoast's 48RE Category 3 transmission also comes with new overdrive and lockup solenoids. The governor pressure sensor (transducer) is also replaced with a new unit. Additionally, all new 48RE transmissions get upgraded with a DNJ billet solenoid housing and upgraded governor solenoid.
A billet triple disc torque converter is included with this Suncoast 48RE transmission and is lined with carbon graphite clutch material and is equipped with a precision-CNC-machined, forged billet apply piston to ensure no deflection occurs. This in conjunction with SunCoast's billet cover ensures many years of performance and reliability. Also installed is a double deep trans pan to increase the available fluid, helping dissipate heat and ensure enough volume of fluid to keep you burning tires.
Also included with SunCoast's Category 3 transmission and torque converter, is a billet SFI certified flex plate.
