3.CHECK FOR INTERMITTENT OPERATION
The conditions to set this DTC are not current at this time.
Check the gearshift linkage adjustment.
Gear ratio DTCs can be set by problems in the Input and Output Speed Sensor circuits. If the vehicle passes the
Clutch Test and still sets Gear Ratio DTC, check the Speed Sensors for proper operation.
Remove the Ignition Switch Feed fuse from the TIPM.
CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being
startedingear.
WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in
personal injury or death.
Install the Transmission Simulator,Miller tool #8333 and the ElectronicTransmission Adapter kit.
Check the wiring and connectors for the Speed Sensors for a good connection, then perform a wiggle test using the
Transmission Simulator.
This DTC can also be set under extreme temperature conditions, this is usually caused by an internal problem.
Verify if the problem is only experienced under extreme hot or cold conditions.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.

When Monitored:
Initially at ignition on, then every 10 seconds thereafter. The solenoidswill also be tested immediately after a
gear ratio error or pressure switch error is detected.
Set Condition:
Three consecutive solenoid continuity test failures, or one failure if test is run in response to a gear ratio or
pressure switch error.
Possible Causes

Theory of Operation
Four solenoids are used to control the friction elements (clutches). The continuity of the solenoids circuits are peri-
odically tested. Each solenoid is turned on or off depending on its currentstate. An inductive spike should be
detected by the PCM during this test. If no spike is detected, the circuit istested again to verify the failure. In
addition to the periodic testing, the solenoid circuits are tested if a gear ratio or pressure switch error occurs. In this
case, one failure will result in the appropriate DTC being set. The MIL willilluminate and the transmission goes into
neutral, if the DTC is set above 35 Kmh (22 mph), Limp-in mode when vehicle speed is below 35 Kmh (22 mph).
