Sun Coast transmission includes a new, custom tuned TCM, Sun
Coast designed "M3GA" clutch drum, increased clutch count, custom
valve body and many hard part modifications. *Core deposit required.
SunCoast complete transmission assembly offers you the ultimate
in performance and durability for your 6.7L Cummins. Boasting
40% more surface apply area than a stock 68RFE, the oversized
double sided SunCoast designed clutches are the key to success
in getting these 68RFE’s to hold anything you can throw
at it. The oversized clutches are housed in our patented billet
inner and outer “M3GA” drum setup, to utilize
every square inch of available real estate inside of the transmission.
All billet hard parts are designed and manufactured in house
here at SunCoast as a result of endless hours of research
and development. The low and reverse sprag have been upgraded
to our spring & roller sprag setup. The 4C snapping retainer
has been upgraded with our billet snapping retainer as well
as the 2C and 4C valve body seals replaced with our billet
units to prevent factory seal blowouts. Every M3GA68 pump
is machined to replace worn TC limit valves and line pressure
modifications to allow more pressure. All hard parts are inspected,
machined, modified or replaced to meet our specification and
all units are tested prior to shipment to insure the ultimate
in performance and reliability to the customer. Included with
the purchase of a M3GA68 is a billet input shaft, custom valve
body modifications, as well as new bushings, seals, rings,
frictions, and steels. Not included yet highly recommended
with the purchase of a complete transmission is a Mag-Hytec
Deep Pan, Triple Disc Torque Converter and an SFI Approved
Billet Flex plate/Flywheel.
