GM Allison GMax-6-3 2006-2012 Alto Manufactured, SunCoast Designed

Quick Summary

Clutches/Steels/Pressure Plates/C3/4 Pistons, TransGo® Shift Kit® Hydraulic Upgrades parts, LU boost valve, A1-PR shim and tool. Comes with complete paper and rubber gasket set, both spin on filter and pan filter with our Filter Loc. All kits have been designed and tested by SunCoast with parts that have been designed and/or manufactured by us. All items included in this kit are recommend and used by SunCoast.

Parts included are:
C-1- Custom stepped apply plate, (8) Carbonite C1 external clutches, (8) Carbonite internal splines clutches with a custom C1 top plate.
C-2- Custom stepped apply plate with (7) C-2 frictions and (7) steels.
C-3- includes our (6) Carbonite double sided frictions with no center slots and a waffle pattern in the material to help retain oil to cool clutch when it’s not applied. (5) Custom steels with no center slots. This design works great in your daily driver, towing and even your extreme race conditions. SunCoast has also redesigned the apply piston with improved rubber compounds that are proven to hold more heat if the circumstances arise. The custom piston allows us to use our thicker spring apply plate that replaces the thin OEM one deflects from the spring pressure and causes a uneven surface for apply. This plate also redirects the oil to better lube plates from the inside out which lubes the entire friction rather than OEM style that lubes from the center out leaving the inter half of the clutch burnt. Top apply plate is also machined and included with kit.
C-4- includes (6) Carbonite single sided waffle pattern external frictions and (6) Carbonite single sided waffle pattern internal frictions. SunCoast also has redesigned the apply piston for C4 with improved rubber compounds that is proven to hold up to more heat if put in that situation than the OEM brands will. The custom piston allows us to use our thicker spring apply plate that replaces the thin OEM one that deflects from the spring pressure and causes a uneven surface for apply. This plate also redirects the oil to better lube plates from the inside out which lubes the entire friction rather than OEM style that lubes from the center out leaving the inter half of the clutch burnt. Top apply plate is also machined and included with kit.
*C5 clutches are NOT included do to the fact they are normally good to re-use unless the unit has been contaminated by water or other foreign elements. C5 clutches are optional and can be added to our kit upon request.

Other parts included in kit are P-1 shim, lockup boost valve, a shim to shim pressure regulator spring and a tool to make it easy to install. TransGo Jr shift kit are also included. This kit includes smart clutch control valves for increased durability and Short-Crisp-Smooth-up shifts/ kick downs. The Jr also reduces trouble codes.

Suncoast Allison paper and rubber kit includes all seals, gaskets and o-rings required to overhaul the Allison 1000. We work directly with the manufacture of our seal kits, so any improvements/revisions are passed on to manufacture and our kits are upgraded to pass the quality on to our customers. We include a new spin on filter and new sump filter along with our billet filter loc to prevent filter from working lose and dropping out of the pump.
