To increase the capacity of standard COMPETITION ELIMINATOR series transmission to handle higher engine
output, several billet components have been incorporated into the COMPETITION ELIMINATOR M/T series-
following details will assist you in understanding, what these components are.
Use of BILLET and structurally reinforced components.
Years of innovation and technology have lead to the development of high strength
components that eliminate areas that could not standup to the stress demands of todays' huge engines. We are now able
to incorporate these innovations into our COMPETITION ELIMINATOR M/T to provide the performance and reliability
necessary to transmit the high torque and high horsepower produced.
Billet components are machined from high strength blocks of steel or aluminum that are also heat treated
in some cases, to provide strength and durability that the stock cast components could not provide.
NOTE: When used under the harsh conditions and high rpm
levels of mega engines, the stock cast components not only fail, but can explode destroying
the vehicle, the engine and more seriously can lead to critical personal injury.
COMPONENTS USED IN THE COMPETITION ELIMINATOR M/T
-GRADE 8 FASTENERS are used on all critical component mating
surfaces. These fasteners prevent bolt breakage and loosenig of components due to bolt stretch. These fasteners
assure continued torque application at all critical components that otherwise could result in leakage, fluid crossflows
-6AN Aircraft Aluminum cooler line fittings provide secure
leak free connections that will not crack or come loose under vibration. These fittings also create a substancially
higher fluid flow rate than stock fittings.
All of the internal fluid passages are increased in size to sustain higher flow rates than a stock
727 and provide the lubrication flow necessary to cool and lubricate under extreme conditions.
Precision machined pump assembly featuring moly burnished hardened ground pump
gears, precision ground rotor chambers provide maximum efficiency, pressure and fluid volume.
The pump cover features a superior quality pump seal, a staked in quality
babbit bushing and a new case vent.(Competition models have this vent closed and relocated to the rear).
The high drum/stator support bearing surface is molybdenum burnished to drastically reduce
friction and accelerated wear.
Chromium seal rings that provide maximum seal under extreme pressures, are installed in
champhered ring grooves reducing side load wear.
Grade 8 bolts are used to attach the support to the pump cover and to attach the pump to
the transmission housing. NOTE: THE HIGH VOLUME PUMP
Precision polished input shaft , forward clutch hub and drum
The input shaft is carefully inspected, ground to tight tollerences at bearing surface,
ring grooves champhered and output shaft bearing installed.
The input drive hub is machined to ensure complete clutch spline contact for maximum torque
capacity. The oil relief holes are enlarged to increase fluid flow to the high clutch pack for improved cooling and
maximum fluid surface contact on high frictions for dramatic wear reduction. The inner surfaces on the piston
side are polished to assure complete lipseal contact for maximum piston apply pressure.
The outer drive drum is champhered and stress relieved to increase torque capacity.
CNC machined C1040 BILLET STEEL or 7075 T6 BILLET ALUMINUM HIGH GEAR DRUM is used in every SMR MEGA
TORQ 727. Any application which will see street use will utilize the steel drum while
competition only applications will use the aluminum version.
A BILLET ALUMINUM APPLY PISTON which provides 55% more piston apply area and doubles
the clutch clamping force than stock is used in either drum. This results in double the clamping
force of stock.
5 or 6 clutch plates are used (depending on the specific application).
Dual oil apply passages provide even piston apply for maximum clutch capacity.
In addition to the obvious performance advantage of these drums, the most
important issue is SAFETY. This billet drum helps prevent the violent and catastopic
explosion that could occur with the use of the stock powder metal forging, in the event of a driveline and/or sprag failure.
HIGH GEAR RETURN SPRINGS and BILLET RETAINER The life
of the high gear clutches under severe duty depends the proper apply pressure of the high gear return spring
assembly. These new springs assure clean 2-3 upshift timing and prevent high gear clutch
drag in higher r.p.m. 1st and 2nd gear ranges, which leads to premature clutch wear and early failure.
The Billet Aluminum Retainer maintains even apply pressure and prevents the possibility of retainer failure.
|the ULTRA SPRAG - roller clutch assembly
THE "ULTRA SPRAG" is the strongest,
most reliable, roller clutch available.
For years the roller clutch (often referred to as the sprag) in the Torqueflite 727 was the weakest link and feared by
most for its' devistating impact on the transmission if it failed. The steep ramps and weak cast-in support in the rear
of the case would often fail in the event of driveline breakage or low gear burnouts.
Attempts were made to reduce this problem by drilling and threading the outer race to permit bolts through the case to
anchor it more securely, however under high torque applications the outer race would fail at the drilled bolt holes often
leading to high drum explosion.
The new design in roller clutch utililizes 16 rollers instead of the stock 12
providing a 30% apply capacity increase. The ramp angles on the outer race are substancially reduced
resulting in much less outward shock load and a thicker stronger outer race preventing breakage of the outer race. The
spring cage is dramatically heavier than the stock unit to prevent the common rollover problem.
The roller race is secured to the case with 6 Grade 8 screws.
PROVIDING THE BRUTE STRENGTH and RELIABILITY TO THE OUTPUT SECTION -WE UTILIZE
The BILLET STEEL REAR SUPPORT provides the ultimate drivetrain stability
and axial support possible for the 727. Its' inherent strength effectively reduces the deflection
and shaft misalignment that can lead to accellerated wear on clutches, planetaries and bushings, resulting in greater
reliability and reduced component drag.
Unlike the modified stock aluminum supports with internal roller bearings providing support to the output shaft
and low/reverse drum used by many, this billet steel support utilizes heavy duty BALL BEARINGS that drastically
reduce resistance, provide dynamic load capacity (that eliminates shearing off the bearing support under extreme torque loads),
provides unrestricted lube flow to the output shaft and planetaries (needle bearings in the support create restriction in
lube flow generating heat) and provide stability for the rear drum preventing band drag and early wear.
THE REAR SUPPORT KIT INCLUDES:
-Billet Steel Rear Support,
-Rollerized Low/Reverse Drum,
-Modified, Light weight Park gear; and
-Billet Aluminum Governor Eliminator
|5 PINION PLANETARY USED IN THE COMPETITION ELIMINATOR M/T
NEW - not remanufactured
5 PINION SOLID STEEL PLANETARY
When increasing the torque load on the 727, the stock cast aluminum
4 pinion carrier with its' stamped splines pose a serious weak link by stripping out on a hard 1-2 shift.
This not only stops your vehicle from being able to drive the rear wheels, it also
fills your transmission and even your converter with aluminum particles, requiring a complete rebuild.
This planetary set replaces the weak aluminum carrier and splines with a much stronger steel
carrier and increased load capacity of 5 pinion gears to transfer the torque load.
|HIGH PERFORMANCE BAND UTILIZED
|BILLET SERVO & SPRING RETAINER
A BILLET STEEL INTERMEDIATE BAND APPLY STRUT, BILLET ALUNIMUM FRONT SERVO COVER and the ROLLERIZED LOW REVERSE
DRUM ARE NOT SHOWN, BUT ARE INCORPORATED INTO THIS TRANSMISSION AS DESCRIBED.
IN COMPARISON WITH OUR MEGA TORQ series TRANSMISSION,
YOU WILL NOTE THAT
THE COMPETITION ELIMINATOR M/T series:
-A QUALITY RE-MANUFACTURED
CASE IS UTILIZED as opposed to a new (never assembled, case;
-THE FRONT PINION BACK, OUTPUT SECTION UTILIZES BEARING WASHERS -instead of the Torrington roller bearings;
-THE DEEP PAN IS THE MOPAR PERFORMANCE - STAMPED ALUMINUM.
ALTHOUGH THE COMPONENTS OF THE MEGA TORQ CAN BE ADDED AT AN OPTIONAL COST,
THESE CHANGES ALLOW US TO PROVIDE YOU A HIGH QUALITY, HIGH TORQUE TRANSMISSION AT A LOWER COST.
