The Category 2
The SunCoast Category 2 E4OD transmission includes our bushing kit, TransGo Tugger Kit, solenoid pack, 45 element intermediate sprag, intermediate band, and billet 300 managing input shaft.
The Clutch Kit
This new E4OD transmission includes Alto Red Eagle clutches along with Kolene steels.
Red Eagle Friction is the go-to material for most performance applications. The lining has a unique dual-saturation, which imparts high friction coefficients and high heat resistance. Red Eagle clutches are designed to limit the amount of "slip" by providing a shorter lock-up time, generating less heat.
The proprietary process starts with the friction paper saturated in a phenolic resin, cured, and then saturated a second time in a silicate. The silicate imparts high heat resistance.
Red Eagle clutches:
- Are designed with a softer, more resilient base paper.
- Assure less wear against opposing steel plates.
- Reduce the incidence of steel plates burning and warping.
The Intermediate Sprag
The factory sprag in the E4OD transmission unit is notorious for failing when exposed to high levels of fatigue. This could include vehicles exposed to heavy towing or hauling or just higher-than-normal torsional fatigue. These factory sprags are typically 24- or 34-element sprags. In all SunCoast builds, these are replaced with heavy duty 45 element sprags. This is an increase of up to 53% over the factory, offering unmatched performance and ensuring that premature failure does not occur.
Transgo Valve Body Calibration Kit
The valve body is the central nervous system of your transmission. Everything that transpires within the unit begins here. In our SunCoast builds, we exclusively use the TransGo HD2 Tugger Kit. This valve body calibration kit is perfect for exhaust braking and doubles the low clutch holding pressure in manual first gear for reliable downhill braking. You also have the ability to adjust shift firmness to your desired preferences. With the improved converter feed capacity, you benefit with better cooling and lubrication.
Corrects/Prevents/Reduces:
- Codes 628, P1740, P1744
- Soft shifts
- 2nd and 3rd burn-up
- Converter burn-up
- Reverse delay
- No reverse hot
- Converter slide/shudder
- Pump buzz
Also Includes:
- Pressure regulator boost valve
- 1-2 shift valve spring
- Line regulator valve
- Innovative line-to-lube components
- High temp direct clutch seal
- Coast clutch HD snap ring
- OD housing spiral lock snap ring
- Updated direct clutch outer seal
- Calibration plate for firmness adjustments
- Quick-fill valve
- L/R mod boost valve
New Solenoid Pack
The E4OD is equipped with a solenoid pack that controls shifting from gear to gear. This solenoid pack is comprised of electromagnetic solenoids. The integrity of these solenoids is imperative, as the flow rate and spray pattern could affect shift quality and clutch life. When failure occurs within the unit, it is not uncommon that the same particles and sediments you find in the bottom of the pan are also in the solenoids. This contamination of the solenoids can and will affect the fluid delivery to critical circuits within the unit.
In this SunCoast E4OD transmission, we replace the solenoid pack with a new one to ensure consistent shifts and long clutch life.
New Bushing Kit
As with any standard rebuild, this E4OD transmission also includes a new bushing kit, which also includes a new front pump bushing.
Intermediate Band
This SunCoast Category E4OD Transmission also includes a new carbon fiber band. This band is used in manual second gear and during downshift engine braking. The carbon fiber material in this band is made to withstand a much higher heat range versus the factory material.
