WARNING

To avoid personal injury or death, carefully read and understand all instructions before attempting to operate any equipment or tools. Do not operate or work on a machine unless you read and understand the instructions and warnings in this and all other applicable manuals. Contact Dealer Service Tools for replacement manuals. Proper care is your responsibility. Always follow all State and Federal health and safety laws and/or local regulations.

To prevent possible damage to your hearing, always wear ear protection when using this tool and/or working around noise generating tools.

To avoid eye injury, always wear protective glasses or face shield. Make sure no one can be injured by flying objects or debris when using tools or working on a component.

Clean up all leaked or spilled fluids immediately. Oil, fuel, or cleaning fluid leaked or spilled onto any hot surfaces or electrical components can cause a fire, resulting in personal injury or death.

Personal injury can result from slips or falls. DO NOT leave tools or components laying around the work area and clean up all spilled fluids immediately.

Personal injuries can occur as a result of using pressurized air. Maximum air pressure at the nozzle must be below 205 kPa (30 psi) for cleaning purposes. Wear protective clothing, protective glasses, and a protective face shield when using pressure air.

Hazard Avoidance

To avoid damage to the transmission and/or personal injury, it is the responsibility of the user to obtain and read any operating instructions concerning proper transmission testing procedures. Always verify you have the most up to date information before testing the transmission.

To avoid damage and/or personal injury, keep all liquids away from the transmission analyzer and dealer supplied PC. Follow all electrical safety procedures to prevent injury or death by electrical hazards.

Prohibited Action

WARNING WARNING

Do not use the 277-2363 Transmission Analyzer III in the transmission test mode with the transmission in the machine. Using the analyzer to shift the transmission while it is in the machine can be harmful to the transmission and dangerous for the operator. The transmission must be mounted on a hydraulic test stand for the transmission test mode.

The transmission should not be rotating while using the “Solenoid Test” screen. Energizing a solenoid while the transmission is rotating can be harmful to the transmission and dangerous for the operator.

General Information Section

Introduction

The 277-2363 Transmission Analyzer III operates electronically-controlled Caterpillar transmissions. These include the Powershift planetary, the Powershift countershaft, the ICM (Individual Clutch Modulation), the Challenger Tractor, the H-Series Motor Grader, and the ECPC (Electronic Clutch Pressure Control) transmissions. The analyzer is used in conjunction with a dealer-supplied computer. The analyzer and computer control these transmissions instead of the vehicle harness and the electronic transmission controls that are on the machine. This allows the technician to check Caterpillar transmissions on the hydraulic test bench, independent of the machine.

The following features are available in the Transmission Analyzer III:

•Easy to use software and Graphical User Interface allows the operator to quickly step through different operations. The Transmission Analyzer III checks solenoid operation, preforms a transmission shift test, checks shift lever operation, and runs special tests for specific transmissions.

•Controlled by a dealer-supplied PC running the included transmission analyzer III software. This allows for easy updates and provides for expanded features and new, more complex transmissions.

•Connects directly to the solenoids of an electronically shifted Caterpillar transmission.

•Outputs PWM (Pulse Width Modulated) current to the initialized solenoids, as required by Challenger and Electronic Clutch Pressure Control transmissions.

•Capable of turning on solenoids in a timeline sequence, as required for the H-Series Motor Grader. It is also capable of modulating current to one, or all, of the initialized solenoids at any point in time.

•Performs automatic or manual testing for shorted, and open solenoid coils, on one or all of the transmission solenoids. The analyzer will also alert you to an intermittent problem with the solenoid coil.

•Checks shift lever function on a transmission that is not controlled by the Autoshift electronic transmission control feature.
