SUNCOAST GMAX-CAT1-LMM-07510-4WD-LC ALLISON CAT 1 500 HP TRANSMISSION WITHOUT CONVERTER FOR 07.5-10 GM DURAMAX 4WD

 

 

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/Raybestos 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.
