Legal and Emissions Information
This publication is intended to provide information about the Supermatic Transmission and related components. This manual also describes
procedures and modifications that may be useful during the installation of a Supermatic Transmission. It is not intended to replace the
comprehensive service manuals and parts catalogs which cover Chevrolet engines and components. Rather, it is designed to provide
supplemental information in areas of interest to "do-it-yourself" enthusiasts and mechanics.
This publication pertains to transmissions and vehicles which are used off the public highways except where specifically noted otherwise.
Federal law restricts the removal of any part of a federally required emission control system on motor vehicles. Further, many states have
enacted laws which prohibit tampering with or modifying any required emission or noise control system. Vehicles which are not operated on
public highways are generally exempt from most regulations, as are some special interest and pre-emission vehicles. The reader is strongly
urged to check all applicable local and state laws.
Many of the parts described or listed in this manual are merchandised for off-highway application only, and are tagged with the "Special Parts
Notice" reproduced here:
Special Parts Notice
This part has been specifically designed for Off-Highway application only. Since the installation of this part may either impair your vehicle's
emission control performance or be uncertified under current Motor Vehicle Safety Standards, it
should not be installed in a vehicle used on any street or highway. Additionally, any such application could adversely affect the warranty
coverage of such an on-street or highway vehicle.

System DO's and DON'Ts:
Do:
•
Fill the transmission with the proper DEXRON®VI (P/N 88861037 US, Canada 19264717) oil using the approved procedure in this I sheet.
•
Use an appropriate fluid level indicator and tube. In lieu of a dip stick tube/indicator, Chevrolet Performance kit 19418242 may be used.
•
Install the cooler line adapter (if desired) and cooler lines to an appropriate transmission oil cooler.
•
Install an adequate gear selector. This should be one that is capable of at least 2 forward gear selections so the Sport calibration may be
used.
•
Use a Chevrolet Performance Parts Engine Control System to power the transmission control system.
•
Use a Chevrolet Performance Installation kit to install the transmission to the engine (LS style only).
•
Install the Vent Tube Assembly. It is critical to prevent water intrusion into the transmission.
•
Connect the Transmission connector, Output Speed Sensor connector, Bulkhead connector and brake light wire as instructed for proper
transmission operation.
•
4WD models must have a transfer case installed.
•
Ensure a proper length yoke is used to ensure proper engagement with the transmission.
Don't:
•
Do not remove the inserts that are in the transmission housing for the cooler lines. These are required for both the adapter (if used) or
production style cooler lines to function properly.
•
Dis-assemble the transmission or modify anything inside the transmission.
•
Modify the wiring or attempt to operate the transmission without using a Chevrolet Performance Parts Engine Control System.
•
Attempt to use with a carbureted engine or LT style Engine Control System.
•
Do not use this transmission in place of a GM service transmission – the calibration in the transmission control module is not compatible
with production systems.
Supermatic 6L80 Transmission Description and Operation
The Supermatic 6L80 RWD is a fully automatic, 6 speed, rear-wheel drive, electronic-controlled transmission. It consists primarily of a 4-element
torque converter, an integral fluid pump and converter housing, a single and a double planetary gear set, friction and mechanical clutch assemblies,
and hydraulic pressurization and control system.
The 4-element torque converter contains a pump, a turbine, a pressure plate splined to the turbine, and a stator assembly. The torque converter
acts as a fluid coupling to smoothly transmit power from the engine to the transmission. It also hydraulically provides additional torque
multiplication when required. The pressure plate, when applied, provides a mechanical direct drive coupling of the engine to the transmission.
