Diagnostic Test
1.CHECKFORRELATEDDTCS
With the scan tool, check for other transmission DTCs.
If any of these DTCs are present, perform their respective tests first.
Are there any Transmission; solenoid, line pressure, speed sensor, and/or loss of prime DTC’s present?
Ye s>>
Refer to the Transmission category and perform the appropriate symptom. If any of these DTCs are
present, they may cause a Speed Ratio Error. Perform the test for P0944 firstifitispresent.
No>>
Go To 2
2.CHECK IF DTC P0731 IS CURRENT
With the scan tool, perform the 1st Gear Clutch Test. Follow the instructions on the scan tool.
Increase the throttle angle or TPS Degree to 30° for no more than a few seconds.
CAUTION: Do not overheat the transmission.
Did the Clutch Test pass, Input Speed remain at zero?

Go To 3
No>>
Go To 4
3.CHECK FOR INTERMITTENT OPERATION
The conditions to set this DTC are not currently present.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.
If the DTC Event Data shows fault P0731 was set in Park, Reverse, or Neutral,replace the Powertrain Control
Module.
If the DTC Event Data shows fault P0731 set with input RPM = zero, check the input speed sensor and related
wiring.
If the DTC Event Data shows fault P0731 set with line pressure significantly below desired line pressure, check
for the cause of low line pressure (i.e., oil level, mis-installed or damaged primary filter or filter seal, sticking
main regulator valve in pump, etc.).
If the DTC Event Data shows fault P0731 set with the UD pressure switch open (but line pressure matches
Desired Line Pressure), air check the UD hydraulic clutch circuit for leakage per the Service Information. If the
UD hydraulic clutch circuit is OK, replace the solenoid/TRS assembly.
Check the gearshift linkage adjustment.
Intermittent Gear Ratio DTCs can be set by problems in the Input and Output Speed Sensor circuits and/or Speed
Sensor Ground circuit.
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.
Wiggle wiring and connectors while checking for intermittent operation with the Transmission Simulator.
Gear ratio DTCs can also be set under extreme temperature conditions.
Verify if the problem is only experienced under extreme hot or cold conditions.
Were there any problems found.

17.INTERMITTENT DTC
The conditions to set this DTC are not currently present.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.
If the DTC Event Data shows fault P0732 was set in Park, Reverse, or Neutral,replace the Powertrain Control
Module.
If the DTC Event Data shows fault P0732 set with input RPM = zero, check the input speed sensor and related
wiring.
If the DTC Event Data shows fault P0732 set with line pressure significantly below desired line pressure, check
for the cause of low line pressure (i.e., oil level, misinstalled or damaged primary filter or filter seal, sticking
main regulator valve in pump, etc.).
If the DTC Event Data shows fault P0732 set with the UD or 2C pressure switch open (but line pressure
matches Desired Line Pressure), air check the UD and 2C hydraulic clutch circuits for leakage per the Service
Information. If the UD and 2C hydraulic clutch circuits are OK, replace theTransmission Solenoid/TRS assem-
bly.
Check the gearshift linkage adjustment.
Intermittent Gear Ratio DTCs can be set by problems in the Input and Output Speed Sensor circuits and/or Speed
Sensor Ground circuit.

Control Module.
If the DTC Event Data shows fault P0733 set with input RPM = zero, check the input speed sensor and related
wiring.
If the DTC Event Data shows fault P0733 set with line pressure significantly below desired line pressure, check
for the cause of low line pressure (i.e., oil level, misinstalled or damaged primary filter or filter seal, sticking
main regulator valve in pump, etc.).
If the DTC Event Data shows fault P0733 set with the OD or UD pressure switch open (but line pressure
matches Desired Line Pressure), air check the OD and UD hydraulic clutch circuits for leakage per the Service
Information. If the OD and UD hydraulic clutch circuits are OK, replace theTransmission Solenoid/TRS assem-

Air check the Reverse and LR Hydraulic Clutch circuits (in the case) for excessive air leakage.
NOTE: Both Hydraulic Clutch circuitscontain a small bleed orifice , a small amount of air leakage is normal.
The Reverse hydraulic clutch circuit bleed orifice connects to the OD hydraulic clutch cavity. A small
amount of air leakage into the OD hydraulic clutch circuit is considered normal.
