Suncoast Converters 700 HP Custom Allison Transmission GMC | Chevrolet 2001-2017 GMAX-CAT3 | Vivid Racing
This SunCoast Allison billet SFI certified billet flexplate replaces the factory flex plate with an improved billet steel one-piece design. This eliminates the weak factory flex plate. This replacement Allison flex plate is a must with the high torque in conjunction with a better designed torque converter that can transfer torque with no slip. The flexplate is bolted to the crankshaft and then the torque converter to the flex plate. This one-piece billet flex plate is SFI certified to 29.3.
The Input Shaft
The input shaft is the first thing to go south with the Allison transmission. This Allison billet input shaft is built to withstand everything you can throw at it. This new Allison billet input shaft is manufactured from 9310 Vacumelt steel which increases torsional fatigue strength by over 50%. The SunCoast Allison billet input shaft is machined with a larger radius at the turbine spline for added strength. This is a must for vehicles that are lifted with larger wheels and tires, for heavy towing and hauling, and for vehicles with aftermarket turbos.
The Torque Converter
SunCoast Allison 1000 torque converters come in many varieties, from heavy hauling, sled pulling, drag racing, to daily driving. Here at SunCoast we design and manufacture all of our torque converters in house. Because of this unique advantage SunCoast can supply almost any request in regards to stall speed or torque multiplication. All of our SunCoast Allison triple disc converters are outfitted with a heavy-duty forged billet steel cover and give an unbeatable lock-up performance.
All of the SunCoast Allison 1000 torque converters come standard with custom pump and turbine modifications (in house). SunCoast also Tig Welds each individual furnace brazed fin for improved reinforcement. The SunCoast Allison billet triple-disc converter also comes standard with our proprietary trapezoidal clutch teeth.
The Billet C2 Clutch Hub
The Allison transmission is an incredibly robust unit, however, when exposed to conditions outside what it was designed for weak points begin to expose themselves. The factory C2 clutch hub has been known to fail prematurely. This issue is most commonly seen in conditions where larger tire/wheel combinations, heavy towing/hauling, sled pulling, drag racing, and larger shock loads.
SunCoast replaces the factory C2 clutch hub with a much stronger billet piece that is manufactured from 4140 heat treated stress relieved steel. This new Allison billet C2 clutch hub has had the spline lengthened .125 for increased contact area. The spline boss diameter has also been increased by .100 for added strength. This Allison billet C2 clutch hub is installed on all SunCoast 700 horsepower category 3 transmissions.
The Billet P2 Planet
The P2 planet with the Allison transmission can strip or snap as a result of poor tuning, shock load, improperly built transmissions, and higher horsepower applications. This failure can and will result in catastrophic failure and ore immobility. The SunCoast P2 planet is the solution to the issue. This item is manufactured here at SunCoast using 4140 billet steel that is then induction hardened. This item is highly recommended for higher horsepower applications, including sled pulling, drag racing, as well as heavy-duty towing. This planet comes with a machine SunGear which is required for use of the planetary.
New internal wiring harness
Every build here at SunCoast reliability is our number one priority. Each one of our (Category) Allison Transmissions comes with a new internal wiring harness. As the transmission continues to age, the plastic connectors become brittle and will break during disassembly. This will eventually lead to premature failure.
Some other transmissions exclusives include SunCoast proprietary C1, C2, C3, and C4 Alto carbonite frictions/Rabestos SCZ frictions that contain no center slots. These frictions utilize a waffle pattern in the material to help retain oil helping the clutch cool when not applied. Redesigned apply pistons with improved rubber compounds proven to hold higher heat. This custom piston allows us to use a thicker spring apply plate which replaces the thin OEM one that will cone and cause uneven apply surface resulting in premature clutch failure. Custom SunCoast apply plate that redirects fluid to better lubricate frictions from the inside out which lubes the entire friction rather than OEM style that lubricates from the center out leaving the inner half of the clutch burnt. Includes exclusive smart trim/clutch control valve. Includes all items needed to modify the C2 clutch piston for increased clutch durability.
