lock DODGE RAM SRT-10 2006 Service Repair Manual

When the scan tool instructs you to put the Gear Selector in a particular position, you must do so using the selector
switch on the Transmission Simulator.
The LED for the gear position in question must be illuminated on the Transmission Simulator prior to pressing
ENTERon the scan tool.
NOTE: When the scan tool requests the O/D off button be depressed, you must use the O/D OFF button in
the vehicle or you will fail the Shift Lever Position Test with an error code11 or OD-TOW/HALL STUCK
OPEN.
NOTE: If the Shift Lever Position test fails, make sure to note the identification of the TRS Sense circuit for
future reference.
Did the Shift Lever Position test pass?

Continuously with the ignition on and engine running.
Set Condition:
This DTC will set when the desired transmission temperature does not reacha normal operating temperature
within a given time frame. Time is variable due to ambient temperature. Approximate times are starting tem-
perature to warm up time: (-40° F / -40° C - 35 min) (-20° F / -28° C - 25 min) (20°F / -6.6° C - 20 min) (60°

Theory of Operation
The Transmission Temperature Sensor is a variable resistor that changes with temperature, or otherwise known as
a thermister. The temperature of the transmission fluid can affect a variety of electronically controlled transmission
operations such as shift quality, torque converter lock-up, and when and/or if certain OBDII or system self-diagnostic
test are performed. The Powertrain Control Module (PCM) substitutes a calculated transmission temperature value
if a fault is detected in the Transmission Temperature Sensor circuit.

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 (codes P0731 through P0736).
2) An excessive change in input or output speeds indicating signal intermittent will result in codes P0715 and/or
P0720 being 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 has 60 teeth and the output speed sensor has 30 teeth, this
results in a an apparent speed ratio of 1:2 and may cause the DTC P1794 to set.
Diagnostic Test
1.CHECK TO SEE IF DTC P0720 IS CURRENT

CAUTION: Properly support the vehicle and raise all drive wheels off the ground.
