4/19/2023 0 Comments Suncoast transmissionSunCoast also modifies the length of this servo to achieve much crisper shifting. When they drag on release it can cause bind-up issues, scoring of the band material, and of course premature wear. The release of the band can be just as import if not more. As almost everyone in our industry lust over the additional clamping force and much quicker apply time, we often overlook the release of the band. This larger apply surface area allows for not only a dramatic increase in apply pressure giving you an enormous amount of clamping load, but this also allows for a faster shift time. This servo is also larger in apply area, over 20% larger than the factory. This servo is made with 4 sealing rings both teflon and rubber, That is double what the factory uses. SunCoast corrects this by installing a custom cnc'd billet intermediate servo. This bore over time will wear, as it wears cross leaking occurs causing lazy shifts, slips going into 2nd gear, and of course in some events bind-ups and dragging of the band going into 3rd. The factory uses a cast servo, the servo offers two simple o'rings to help control cross-leaking within the bore. This is where our SunCoast billet 2nd gear servo comes into play. The best band in the world is useless without proper clamping force when apply and a quick release off the drum when needed. Our next focus is with the hydraulic integrity of this band acuation. This new SunCoast billet band is also lined with a Carbon Fiber friction material offering the best friction coefficent available. Each one of our units recieves a new SunCoast custom billet band machined in house. SunCoast took a different approach and just redesigned the band all together. You will some aftermarket attempt to use a very rigid material to keep these from flexing or breaking. When even modest attempts of increased apply pressure occur these band break due to the flimsy construction. The band itself from the factory is a very flexible band, these band will stretch and require constant adjustment. When thinking about the amount of torque these trucks can make coupled with the torque multiplication of the converter and it soon becomes apparent why this area could be problematic. This band is wraps around the direct drum (right behind the transmission pump)this drum house the direct clutches (3rd gear). The Torqueflight transmission utilizes a band to shift the transmission into 2nd gear, then this band is release when shifting into 3rd gear. These units include have many upgrades from the factory not just for performance but restoring hydraulic integrity to some very crucial circuts, Here are some listen below: Each one of our calibrations to the valve body, pump, seperator plate, and even the clutch stack-ups are meant with your intended usage in mind. These units are not "cookie cutter" units but rather something individually catered to your specific needs. This base package can be built and improved upon with a plethora of options and upgrades to suit your individual needs. The phrase "copied but never caught" could never be truer than now.Įach one of our Dodge Torqueflite transmissions receive what we call our base packages. Dating back to the days of Redneck nationals and Team Green before outlaw racing was even thought of SunCoast transmissions were breaking records and winning world championships. For over two decades SunCoast has continually led the the industry in both innovation and performance.
