A new ECM can be delivered with the latest software and parameter defaults loaded. When flashing new software to an existing ECM, if possible, perform a configuration file save before flashing the new software to the ECM.
The following table lists the Transmission ECM configurations (Explanation comments are in parenthesis.)
Transmission Configuration Definitions

Ground Speed Limiter Installation Status
The machine ground speed limit on the 980K is determined by setting the machine speed limit.
Transmission Maximum Forward Gear
The transmission maximum forward gear sets the maximum gear that the machine will shift to in the forward direction.
| Transmission Maximum Forward Gear | ||||
| Model | Unit | Increment | Minimum | Maximum |
| 980K | Gear | 1 | 1 | 4 |
Transmission Maximum Reverse Gear
The transmission maximum reverse gear sets the maximum gear to which the machine will shift to in the reverse direction.
| Transmission Maximum Reverse Gear | ||||
| Model | Unit | Increment | Minimum | Maximum |
| 980K | Gear | 1 | 1 | 4 |
Control Throttle Shift (CTS) Enable
The Control Throttle Shift (CTS) lowers the engine speed briefly to reduce the loads on the drive train during a directional shift. This action results in a smoother shift. Select Disabled or Enabled for the 980K CTS configuration.
Tire Rolling Radius
The tire rolling radius setting improves the speedometer accuracy. The tire rolling radius is defined as the distance from the center of the wheel hub to the ground. Enter the tire rolling radius for the tires installed on the machine.
| Tire Rolling Radius | |||
| Model | Increment | Minimum | Maximum |
| 980k | 1 | 885 mm (34.84 inch) | 947 mm (37.28 inch) |
Integrated Braking System (IBS) Manual Mode Enable Status
The Integrated Braking System (IBS) enables the operator to downshift and neutralize the transmission by depressing the left brake pedal.
The Integrated Braking System (IBS) is always enabled in the autoshift modes. The ability to enable or disable IBS applies only in the manual shifting mode. Only the downshift logic is disabled and the neutralizer stays present. To disable IBS in the manual mode, the Integrated Braking System (IBS) manual mode enable status should be set to "Disable". When IBS "Manual Disable" is configured and the transmission control is in the "Manual" position, the transmission will not downshift when the left brake pedal is depressed.
Neutralizer Settings
The transmission will be neutralized when the left brake pedal is depressed to the transmission neutralization setpoint. The 980 K has three neutralizer settings which allow configuration of the neutralizer portion of the IBS. These settings are for application requirements in level, moderate and aggressive slope operation. Adjust the neutralizer settings according to the machine site conditions.
| Neutralizer Settings | |||
| Increment | Minimum | Maximum | |
| Level percent | 0.5 | 0 | 99 |
| Moderate percent | 0.5 | 0.5 | 99.5 |
| Aggressive percent | 0.5 | 1 | 100 |
Level Operation Neutralization Offset Setpoint
The level neutralizer setting should be adjusted and used for situations where the machine is operating on level ground. The level setting cannot be set below the brake point (0.0%) or above or equal to the moderate slope setting.
Moderate Slope Operation Neutralization Offset Setpoint
The moderate neutralizer setting should be adjusted and used for situations where the machine is operating on a moderate incline. The moderate slope setting cannot be set below or equal to the level setting. The moderate slope setting cannot be above or equal to the aggressive slope setting.
Aggressive Slope Operation Neutralization Offset Setpoint
The aggressive neutralizer setting should be adjusted and used for situations where the machine is operating on a steep incline, for the site. The aggressive slope setting cannot be set below or equal to the moderate slope setting or above the maximum allowed setting.
Brake Measurement
The Brake Measurement is used to help calculate the amount of wear for a given brake disc. Each individual service brake uses an indicator pin to help determine the amount of wear on an existing service brake disc. An indicator pin is located on each side of the front and rear axle center housings. The brake measurement information is recorded in the transmission Electronic Control Module (ECM).
| Brake Measurement | |||
| Model | Increment | Minimum | Maximum |
| 980 K | 2.5 mm (0.1 inch) |
0.00 mm (0.00 inch) |
599.44 mm (23.6 inch) |
Record a new baseline value whenever a new brake disc is installed. After entering the new brake measurement values, enter the SMU when these new brakes were installed in the brake measurement hour meter reading. Record a new baseline value ONLY for the respective brakes that received a new brake disc. The baseline value should not be updated for brakes that did not receive a new brake disc. The following information is recorded:
- Right front brake measurement.
- Left front brake measurement
- Left rear brake measurement.
- Right rear brake measurement.
- Brake measurement hour meter reading.
Transmission Type
For the 980 K the machine may be built with a standard or a heavy-duty transmission. The heavy-duty transmission is also referred to as an extreme service transmission in some documentation. For the transmission type select "Heavy Duty" if the machine is built with the heavy-duty transmission. Check the product configuration for individual 980K machines to determine if the heavy-duty transmission is installed.
Advanced Machine Security System Installation Status
The Machine Security System (MSS) protects from vandalism and theft by preventing unauthorized personnel from starting the machine. Machines start only after a unique Machine Security System (MSS) key is inserted into the ignition. MSS keys can be programmed to start the machines only certain days or hours. If the machine is equipped with the MSS attachment, the advanced machine security system installation status should be set to "installed". A factory password is required to install this feature. series models have this feature incorporated into the Transmission ECM. On the 980K this feature is called security system enable command and will be set to " Enabled" if the machine is equipped with MSS.

Transmission Direction Switch #2 Type
The 980 Kmachines may be equipped with a remote Forward-Neutral-Reverse (FNR) switch. The transmission direction switch #2 type should be set to "not installed" if the machine is not equipped with a remote Forward-Neutral-Reverse switch. If the machine is equipped with a remote FNR switch select "Type 1" if the switch is a 246-2642 Rocker Switch that is implement pod mounted. Select "Type 2" if the switch is a 303-9566 Rocker Switch that is a single axis lever with a pod mount or a joystick.

Parking Brake Type
The heavy-duty parking brake that is offered on the 980K provides an enclosed parking brake mounted on the transmission in place of the standard drive shaft parking brake. The heavy parking brake is only available with the heavy-duty transmission. If the machine is equipped with a heavy-duty parking brake, set the parking brake type to "Heavy Duty". If the machine is equipped with the standard parking brake, the parking brake type should be set to "Standard".
Note: If a heavy-duty parking brake is installed on the machine, use Cat ® ET to perform the "Hold Level Calibration" and the "Ramp Level Calibration", instead of the "Transmission Fill Calibration" used in standard transmission models. Transmissions on models equipped with a heavy-duty parking brake, use one less speed sensor than on standard transmission models. With this one less speed sensor, an automatic calibration cannot be performed.
The "Hold Calibration" must be performed prior to the "Ramp Level Calibration". If the calibration is not correct, the quality of the transmission shift can be greatly affected.
Reference For the procedure to perform the "Hold Level Calibration" and the "Ramp Level Calibration" on machines that are equipped with a heavy-duty parking brake, refer to the following in this manual:
