Suncoast Cat5 E4OD 750HP Transmission with Billet Triple-Disc Torque Converter – 4WD (SC-E4OD-CAT5-9597-4WD) for 1994.5-1997 Powerstroke 7.3L

• 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.

• 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 Rebuild Kit 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.

Upgraded Aeromet Input Shaft

The input shaft on the E4OD platform has always been the first weak link to bear its head once additional horsepower is applied. In this Category kit we upgrade the input shaft to Aeromet 100 alloy. The Aeromet material resist torsional fatigue much better than other materials commonly used.

The Forward Drum Upgrade

The Ford E4OD forward drum has been a sore spot for many E4OD owners for quite a few years. These issues date back to the earlier C-6 and E40D platforms with repeated spline failures and snap ring blow outs. In this SunCoast Category E4OD Transmission Rebuild Kit the factory forward drum is replaced with a new billet one. The E4OD billet forward drum is manufactured from 4140 heat treated stress relieved billet steel. This new drum corrects and eliminates the common issues with spline failure and snap ring blow outs.

Upgraded Larger Billet Intermediate Shaft

The Intermediate shaft, also called the center shaft, is the second weakest hard part within the E4OD Transmission next to the input shaft. In this Category E4OD transmission rebuild kit, we upgrade this shaft to much larger billet one.

This new much larger billet intermediate shaft is manufactured from 4140 HTSR billet steel and incorporates a dual bushing support system for increased stability over the OE design. This is the largest intermediate shaft available on the market today. This shaft bolt over a 20% increase in overall diameter. The forward drum comes with both cast and teflon sealing rings.

Billet Overdrive Planetary Housing

In high horsepower applications it is not uncommon to see the overdrive planet housing break, this is especially true during instances of rapid loading and unloading of the suspension. In this SunCoast E4OD Category rebuild kit we replace the factory planetary assembly with a billet overdrive planetary housing to prevent failure. Pinion staking pins are supplied, no welding required.

Billet Output Shaft

The factory output shaft is the last weak link in the E4OD transmission when building a high performance unit. These shafts are mostly prone to torsional fatigue breaks but it is not uncommon to see higher horsepower units cause sheer breakage. To alleviate this issue Suncoast replaces it with a billet output shaft manufactured from 300M material for unmatched strength and performance.
