Introduction

The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.

Problem

Replacement solenoid valves on certain transmissions may fail on the machines listed above.

Transmission controls using replacement solenoid part numbers beginning with 474-xxxx (Table 2, Former Part "474") may stick due to improper clearances.

On rare occasion, replacement solenoid valves may experience slow response resulting in undesired transmission behavior.

In certain Large-Track-Type Tractors, transmission controls using replacement solenoid valves may not respond to rapid, sequential, alternating shift sequences.

Solution

Caterpillar is aware of this problem and recommends the following interim solution.

Prior to replacing solenoid valves, all standard troubleshooting and diagnostic procedures should be followed to resolve contamination and/or harness connectivity failure modes.

If a faulty shift solenoid is suspected, replace the part with the applicable replacement part in Table 2, Replacement Part.

Only use replacement 302-3811 Solenoid Valve Gp from Table 2, Replacement Part, for Large Track-Type Tractor application. Do not use a 474-9387 or 524-2035 Solenoid Valve Gp in these applications.

Ensure the proper torque on the cartridge valve of 50 ± 5 N·m (37 ± 3.7 lb ft). Refer to Table 2 for the list of parts replacing the former parts.
