18.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 P0733 was set in the Park, Reverse, or Neutral, replace the Powertrain
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-
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.
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.

P0734-GEAR RATIO ERROR IN 4TH
For a complete wiring diagramRefer to Section 8W
When Monitored:
Continuously with the ignition on, engine running, with the transmissionin gear.

If the ratio of the Input RPM to the Output RPM does not match the current gearratio. This DTC can take up
to five minutes of problem identification before illuminating the MIL.

Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
The transmission system uses two speed sensors, one to measure input RPM and one to measure output RPM.
These inputs are essential for proper transmission operation. Therefore, the integrity of this data is verified through
the following checks:
1) Once in a particular gear, if the gear ratio varies from the correct gear ratio, the corresponding in-gear trouble
code is set (DTCs P0731–36).
2) An excessive change in input or output speeds indicating signal intermittent may result in the DTCs P0715 and/or
P0720 being set.
3) If the common speed sensor ground circuit is lost, both sensor inputs will read the pulses from the input speed
sensor when at a stop in neutral. Since the input speed sensor reads 60 teethfrom the input clutch hub and the
output speed sensor reads 30 teeth from the park gear, the result is an apparent speed ratio of 1:2 and may cause
the DTC P1794 to set.

8.CHECK INTERNAL TRANSMISSION
Remove the Transmission Oil Pan and Valve Body per the Service Informationand check for the following:
Excessive debris in the oil pan.
Remove the Valve Body and check if the accumulator cover is intact and the 4Ctower seal is not cut or split.
OD and 4C accumulator pistons for cracks and/or cut seals.
Solenoid Switch Valve and its plugs for stickiness or wear.
Cut or missing #5 and/or #6 check ball.
OD bleed orifice on top of the Valve Body
Air check the OD and 4C hydraulic clutch circuits for excessive leakage. Refer to the Service information.
NOTE: Both the OD and 4C hydraulic clutch circuits contain a small bleed orifice. A small amount of air
leakage is considered normal. The OD hydraulic clutch circuit bleed orifice connects to the Reverse input
clutch hydraulic cavity. A small amount of air leakage into the Reverse hydraulic clutch circuit is considered
normal.

ing faster than the drive shell is being turned.
