10R80 F Clutch Expanded Capacity

The Expanded Capacity Clutch Modules

The 10R80 transmission, while a very capable unit, has its deficiencies just like anything else when it is asked to perform outside its original design intention. Since it's debut in 2018, Suncoast has been actively involved in research and development of this new platform. With our active partnership with Raybestos powertrain, we can now deliver you the very best product to date with the 10R80 platform. These new Suncoast 10R80 transmission expanded capacity clutch modules that are included are completely drop-in replacements. Absolutely no machining is required.

The "F" Clutch

This clutch is also prone to premature wear as we have seen with other Lepelletier Ravigneaux Gear sets...oncoming clutches in higher gears seems to take the blunt of the beating. With the new 10R80 transmission, the "F" clutch is no exception.

The "F" clutch is engaged in R,4,5,6,7,8 and 9th. The quickest path to early or premature degradation to this clutch pack is wide open throttle or heavy-load-indexed 3rd to 4th shifts. This is especially prominent in applications where torque management has been deleted.

Suncoast has corrected this issue by adding 25% more capacity to this clutch pack by taking it from 4 clutches to 5 in this particular clutch pack.
