SunCoast Category 1 4R100 Rebuild Kit with Billet Triple Disc Torque Converter

• 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.

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.

New Solenoid Pack

The 4R100 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 4R100 rebuild, kit 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 4R100 rebuild kit also includes a new bushing kit, which also includes a new front pump bushing.

Intermediate Band

This SunCoast Category 4R100 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.

The Torque Converter

This Category 1 SunCoast Torque Converter fits all 4R100 transmissions and is engineered to handle all of your everyday duties. Whether you're towing a camper or hauling dirt to a job site, this torque converter is designed to improve vehicle response and give you years of solid, reliable performance. It comes with furnace-brazed fins and hardened turbine splines. The clutches in this converter are carbon-graphitic for precise and accurate lock-up.

If you're looking to increase the performance of the factory unit and looking for a cost-effective solution, this is the converter for you. This converter, while great for heavy duty towing and hauling, is not intended for racing.
