This SunCoast Category 5 47RE rebuild kit includes everything necessary to rebuild your 47RE
transmission. This high-performance rebuild kit is for customers seeking improvement over the
stock unit along with improvements to the band, band actuation, servos, accumulator piston,
forward drum, larger 27-spline input shaft, larger 29-spline output shaft,
billet intermediate shaft, 27-spline stator support and billet direct drum.
The addition of the billet intermediate servo, billet band anchor and billet band strut allow
this kit to address the common know shortcomings of this 47RE transmission. This kit also comes
with a new billet blueprinted 4.4 band lever. The new thrust washer kit also contains selective
for setting endplay.
This rebuild kit also includes our much larger, one-piece, billet 27-spline input shaft. This
shaft is made from 300 maraging steel and is then heat treated and stress relieved to handle the
additional demands of higher torque and stress loads. This shaft is precision ground to exact
tolerances. We're also including our exclusive 27-spline stator support with this kit to
accommodate the larger input shaft.
This Category 5 47RE master rebuild kit also includes a band upgrade. While some of our other
kits include a Raybestos Pro Series carbon fiber flex band, in this kit we use our billet rigid
band. This band is CNC machined from billet steel and then lined with carbon graphite lining to
ensure unmatched performance by any other manufacturer.
In our full competition builds, safety is always at the forefront. One of the biggest upgrades
to this kit is the addition of our Ultimate Weapon Billet Direct Drum. This billet direct drum
is made from 4140 billet steel; this is to ensure the utmost safety when you consider the direct
drum is traveling 2.2 times the speed of the engine. As you can imagine, when things let go at
that speed, the results are catastrophic, and we've all heard the stories of severed limbs with
transmission failures. This drum also maintains conformity at higher RPMs, reducing deflection
when the band is applied. This combination has proven to dramatically reduce shift times. In
addition to the safety features, this drum has an extended snap ring groove to allow the
inclusion of more clutches. This is matched perfectly with the extended height of our 27 spline
input shaft and hub, also included in this kit.
Our Category 5 SunCoast 47RE rebuild kit also includes upgrades to the flexplate. The factory
47RE flexplate is replaced with our SunCoast billet 47RE one piece unit. This new 47RE flexplate
exceeds 29.3 SFI certification. This new billet one piece design is CNC machined from a single
forging, and specific reliefs are machined out between the converter mounting area and the crank
flange to enable minimal designed torsional flex.
We also include the addition of new apply pistons for both forward and direct. SunCoast Category
5 47RE master rebuild kits replace the factory cast pistons with new billet apply pistons. The
direct piston is also included with new custom calibrated springs. The forward piston is also
replaced with a new billet piece. These two improvements allow higher clamping forces without
any deflection occurring. Giving a much more direct shift feel and eliminating potential cross
leaks within the drum.
Another piece included in this kit is our full billet rear clutch retaining hub, made from 4140
heat-treated, stress-relieved billet steel versus the OE cast piece. The factory cast retainer
is known to fail in high torsional fatigue situations such as higher line pressure, commercial
use and heavy duty towing and hauling. This new billet piece is the correction you've been
We also replace the factory intermediate shaft with a billet one. Designed for high torque
& heavy towing applications, the shaft is precision machined and ground from 300 Maraging
steel (VASCOMAX) and heat treated for superior surface toughness and durability. It is made for
high torque engines and is an ideal replacement part to satisfy the demands for extreme off-road
service and high performance applications. The intermediate shaft is spline-machined with large
blended radius to reduce common fractures associated with the OEM design.
Lastly, we include a billet output shaft. Designed for higher horsepower/torque engines, this
performance product has been tested in excess of 1,400 ft/lbs of torque. Shaft is machined from
300M material then Heat Treated for torsional strength and precision ground on all critical
This kit fits all 4WD 47RE transmissions.
