When Monitored:
The gear ratio is monitored continuously while the Transmission is in gear.
Set Condition:
After a controller reset in neutral and a ratio of input to output, of 1 to 2. ThisDTCcantakeuptofiveminutes

(T13) SPEED SENSOR GROUND CIRCUIT SHORT TO GROUND
(T13) SPEED SENSOR GROUND CIRCUIT SHORT TO VOLTAGE

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) When in gear, if the gear ratio does not compare to a known 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 which may result in the DTCs P0715
and/or P0720 to set.
3) If the common speed sensor ground circuit is lost, both sensor inputs will read the signal from the input speed
sensor at idle in neutral. Since the input speed sensor reads 60 teeth from 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 when at a stop.

45RFE/545RFE PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE
For a complete wiring diagramRefer to Section 8W.
1.
Perform the following before attempting any diagnostic procedures:
Check the transmission fluid level. Ifthe fluid level is low, locate and repair any leaks and fill the transmission
to the proper level. Refer to the appropriate Service Information for procedures. Many transmission symptoms
can be caused by a low fluid level.
Check the battery. To avoid false diagnosis, testing should only be performed with the battery fully charged.
With the scan tool, read Engine (PCM) DTCs. If DTCs are present, refer to theDriveability Category and per-
form to the appropriate diagnostic procedure(s) before proceeding.
With the scan tool, read Transmission (TCM) DTCs. Record all Stored, Active, and Pending DTC information.
Diagnose any Pending DTC as a matured DTC.
With the scan tool, read DTC EVENT DATA.Use this data to identify the conditions in which the DTC was set.
Performing a Battery Disconnect will clear all DTC EVENT DATA and reset alllearned Transmission values to
the default values, which may temporarily result in erratic shift schedules.
With the scan tool, perform the Shift Lever Position Test. If the test does not pass, refer to the diagnostic
procedure for P0706 Transmission Range Sensor Rationality.
For Gear Ratio Error DTCs, use the scan tool to view CVI Monitor data. Read and record the Clutch Volume
Index information.
Use the wiring diagram as a guide. Inspect the wiring and connectors related to this circuit. Repair as neces-
sary.
Refer to the When Monitored and Set Conditions for this DTC. DTCs can set at ignition on, at start up, after
driving under specific conditions and after diagnostic monitors have beenrun.
Refer to applicable Technical Service Bulletins (TSBs) for controller software update information. Some condi-
tions can be corrected by upgrading the Engine (PCM) or Transmission (TCM)controller software.
Refer to any Service Information Tune Ups or Technical Service Bulletins that apply.
Were there any repairs made that fixed the vehicle?

RELAY-TRANSMISSION CONTROL
DESCRIPTION
The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power to the solenoid pack
when the transmission is in normal operating mode.
OPERATION
When the relay is “off”, no power is supplied to the solenoid pack and the transmission is in “limp-in” mode. After a
controller reset, the TCM energizes the relay. Prior to this, the TCM verifies that the contacts are open by checking
for no voltage at the switched batteryterminals. After this is verified, the voltage at the solenoid pack pressure
switches is checked. After the relay is energized, the TCM monitors the terminals to verify that the voltage is greater
than 3 volts.

Theory of Operation
The Transmission Temperature Sensor is used to sense when the transmissiontemperatureistoohotortoocoldto
operate overdrive and/or the torque convertor clutch. When the transmission sensor detects a temperature below 0°
C (32° F), overdrive and the torque convertor clutch are disabled. When thedetected temperature is above 127° C
(260° F), overdrive is disabled and 3rd gear with TCC is engaged, this strategy is used to increase transmission
fluid flow to help cool the transmission.
When Monitored:
Continuously with the ignition on and the engine running.
Set Condition:
The DTC will set after two consecutive trips in which the transmission oil temperature is greater than 5° C (40°
F) and the transmission oil temperature does not rise more than 8° C (16° F) after 20 minutes of run time with
a vehicle speed greater than 48 Kmh (30 mph). The DTC will also set if the engine temperature is greater than
38° C (100° F) with the transmission oil temperature greater than 127° C (260° F).
