The planetary gear sets provide the 6 forward gear ratios and reverse. Changing gear ratios is fully automatic and is accomplished through the use
of a transmission control module (TCM) located inside the transmission. The TCM receives and monitors various electronic sensor inputs and uses
this information to shift the transmission at the optimum time.
The TCM commands shift solenoids and variable bleed pressure control solenoids to control shift timing and feel. The TCM also controls the apply
and release of the torque converter clutch which allows the engine to deliver the maximum
fuel efficiency without sacrificing vehicle performance. All the solenoids, including the TCM, are package into a self-contained solenoid valve
assembly located inside the transmission.
The hydraulic system primarily consists of a vane-type pump, 2 control valve body assemblies, converter housing and case. The pump maintains
the working pressures needed to stroke the clutch pistons that apply or release the friction
components. These friction components, when applied or released, support the automatic shifting qualities or the transmission.
The friction component used in this transmission consist of 5 multiple disc clutches. The multiple disc clutches combine with one mechanical sprag
clutch to deliver 7 different gear ratios, 6 forward and one reverse, through the gear sets. The gear sets then transfer the torque through the
output shaft.
The transmission may be operated in any of the following gear ranges:
PARK (P) This position locks the output shaft and prevents the vehicle from rolling either forward or backward. PARK is the best position to use
when starting the vehicle. Because the transmission utilizes a shift lock control system, it is necessary to fully depress the brake pedal before
shifting out of PARK. For safety reasons, use a parking brake in addition to the PARK position.
REVERSE (R) This position allows the vehicle to be operated in the rearward direction.
NEUTRAL (N) This position allows the engine to be started and operated while driving the vehicle. If necessary, the engine may be started in this
gear or while the vehicle is moving, should it be necessary. This position should be also used when towing the vehicle.
DRIVE (D) Drive range should be used for normal driving conditions for maximum efficiency and fuel economy. Drive range allows the transmission
to operate in each of the 6 forward gear ratios. Downshifts to a lower gear, or higher gear ratio, are available for safe passing by depressing the
accelerator or by manually selecting a lower gear in the manual mode range.
SPORT/MANUAL MODE (M) This position is "one click" below D. Sport/manual mode activates the Sport Calibration. The transmission will up-shift
and down-shift but uses the Sport Shift and Pressure Tables of the calibration. This calibration is firmer and shifts at higher speeds. If using a Tap
shifter or paddle shifter, the first requested "tap" gives full manual control of the transmission. This allows the driver to select a range of gears
appropriate for current driving conditions.
The weight of the transmission is approximately 95.1-103.7 kg (209.7-228.6 lb). The gear ratios of the transmission are as follows:

To protect the engine and/or transmission from damage, the TCM will only allow shifting into a gear appropriate for the engine speed and vehicle
speed.
The torque rating of the 6L80 Supermatic Transmission is 650 lb ft. This transmission has been manufactured with updated parts to meet this
requirement and is not equivalent to a GM service transmission. It should not be substituted for a GM service transmission and will not operate
correctly if installed in production vehicle.
The Supermatic 6L80 transmission is based on production 6L80 from a 2015 - 2018 Chevy Silverado. Any service parts needed can be referenced to
a 2015 - 2018 Silverado with a 6L80 (MYC). This transmission kit includes the transmission harness, designed to be used with Chevrolet
