Complete setup
Install the latest version of Cat Electronic Technician (ET). Cat ET must be configured to a resolution of 240 data points per minute.
Configure the data log. Use the following conditions for the data log. Refer to Special Instruction, REHS3407, "Using the Caterpillar Electronic Technician (ET) Data Log". Refer to Illustration 3, Illustration 4, Illustration 5, and Illustration 6 in order to aid in the setup.

An Allison Service Technician must lock the transmission into the correct gear for the torque converter stall test. A similar operation must be done for a Caterpillar transmission. This will only allow the transmission to be in the direct gear and the torque converter.
When operating a transmission at stall conditions, the vehicle must be prevented from moving. Serious injury or death may result. Both the parking brake and the service brake must be applied. The vehicle must also be blocked to prevent movement. Warn personnel to keep clear of the vehicle and its travel path.
Warm the engine and the transmission. The engine coolant temperature must be above 88 °C (190 °F). The transmission oil must be above 66 °C (150 °F).
Apply the parking brake.
Turn the fan to On.
Start recording data.
Fully depress the service brake. The vehicle must be in fourth gear.
Quickly depress the throttle to the limit. Hold down the throttle for fifteen seconds.
Place the vehicle in neutral. Allow the engine and the transmission to cool by running the engine at 1500 rpm for one minute.
Repeat Step 8 through Step 10 three times. (5) Stop recording the data. Save the data. Attach the data log to SIMSi. (6) If additional assistance is needed contact your Dealer Technical Communicator for submittal to the DSN. (7) The vehicle engine meets the torque converter stall test or the vehicle engine exceeds the torque converter stall test. (8) Perform the 0-20 Acceleration Test.
Turn the fan On.
Start the data logger for a few seconds before quickly depressing the throttle. The throttle is depressed at time "0".
Run the vehicle past the 32 km/h (20 mph) before stopping the data log.Note: The actual time for the vehicle to reach 32 km/h (20 mph) may be longer than the transmission performance report. The transmission performance report assumes a full throttle and the brakes locked.Graph
