The valvebody is the brain of your transmission. It regulates hydraulic pressures, controls
precise shift timing and apply and release circuits, monitors governor pressure, converter feed and cooling functions.
A properly designed and constructed valvebody is critical for maximum performance and reliability
of your transmission.
Installing an SMR TRANSMISSIONS prepared valvebody, assures precise control
in a quality constructed Torqueflite transmission.
Every SMR TRANSMISSIONS VALVEBODY
- Thoroughly cleaned and carefully inspected for any cracks, burrs or warpage that
may have developed;
- All spool valves are polished and if not within strict tollerances, replaced with revised
- Valve bores are honed where necessary to assure total seal functions;
- Mating surfaces are resurfaced to prevent leakage and crossflow into other circuits;
- Specific modifications for the application are precisely performed to main casting,
transfer plate and separator plate;
-Vital shift and pressure springs are replaced to renew their original charteristics and/or
to increase the performance levels as required by the application;
- Manual valve alignment is carefully checked to assure clean shift activation without
pressure loss between gear changes;
- The valvebody is carefully assembled, presssure settings precisely adjusted and the
unit is then pressure tested to assure that there is no leakage and that functions are correct for design.
Additionally, all SMR valvebodies(except '62-65) incorporate ANTI-DRAINBACK VALVING and FULL TIME LUBRICATION. These
features assure immediate converter charge and lubrication upon start-up. Without this feature, the
fluid drains off while parked, requiring converter, lube, cooling and apply circuit refilling upon startup which aerates the
fluid with air/fluid mix which in turn does not provide full apply pressure on clutches, converter and cooling system which
in turn accelerates wear.
TORQUEFLITE 904 and 727 MODEL LINEUP
(3 SPEED AND 3 SPEED WITH GEAR VENDORS OVERDRIVE)
Series: Restores the valvebody to the original shift characteristics of the
vehicle for which it is designed. Upgrades are incorporated to improve reliability without altering its' original shift
characteristics. The vehicle will feel like it did when the original owner first cruised down the boulevard with
his dream car.
Requires all original linkage and settings.
Provides a firm shift with full automatic shifting when placed in the Drive position. Manual shifting 1-2, 2-3 and 3-2
capability is provided.
Apply circuits are re-calibrated to reduce overlap (bind-up) and pressures are increased for firmer shifts
and greater reliability.
Ideally suited for Heavy duty, Street and Street/Strip use.
Note: Requires properly functioning Throttle linkage or cable (kick-down) assembly.
very firm shifts, higher shift point, with full automatic shifting when placed in the Drive position. Manual shifting
1-2, 2-3, 3-2 and 2-1 capabilities are provided.
Apply circuit are re-calibrated for maximum overlap reduction in an auto shift pattern and apply pressures
are substancially increased to provide competition firm shifts and increased clutch bearing capacity.
Ideally suited for high performance street and competition use where automatic shifting is preferred.
Note: Requires properly functioning throttle linkage or cable (kick-down) assembly.
- REVERSE PATTERN - "Our ultimate valvebody"
Unlike our other valvebodies, this valvebody (when placed in Low gear),utilizes the application of the one-way
roller clutch (sprag) for 1st gear, when shifted to 2nd gear, it applies the Intermediate band which simply causes the one-way
roller to override. This results in the cleanest 1-2 shift possible because there is no overlap
from having to apply the intermediate band while the low/rev band is still applied.
Further as a result of the flow characteristics of the reverse pattern circuitry, we are able to increase 2nd servo
release apply quickly while applying the high gear clutches instantaniously for totally clean 2-3 shift.
Not only do these shift characteristics provide maximum performance, they also substancially
improve reliability in competition applications
COMPETITION ELIMINATOR-LOW BAND APPLY - REVERSE PATTERN - ALLOWS SHIFTS TO HOLD IN LOW and SHIFT BACK TO LOW from 2nd without coming
to a stop.
FOR USE IN STREET and VARIOUS
OFF-ROAD APPLICATIONS where the ultimate in 1-2 shift is not as desirable as having control of Low Gear apply at any
ALL OTHER FEATURES of our COMPEITITON ELIMINATOR ""Our Ultimate Valvebody" Reverse
Pattern valvebody are incorporated to maximize performance and reliability.
SPECIAL NOTE: both
of our COMPETITION ELIMINATOR Reverse pattern valvebodies will install in all years of 727 and 904 from 1966 to 1993,
including lock-up models. However the lock-up function will not be activated.
valvebody will install and perform the same characteristics in the A500-A518-A618 (42-47) RH & RE transmissions.
