lock DODGE RAM SRT-10 2006 Service Repair Manual

SOLENOID-REVERSE LOCKOUT
DESCRIPTION
The reverse lockout solenoid prevents shifting into reverse when the vehicle speed is greater than 5 mph. Solenoid
is threaded into the left side of the transmission.
OPERATION
When vehicle speed is less than 5 mph, the PCM provides a ground for the solenoid (energized) and allows shifting.
When vehicle speed is greater than 5 mph, the solenoid is deactivated and prevents the transmission from being
shifted into reverse.

TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)

When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
DTC will set when the transmission temperature does not reach a normal operating temperature within a given
time frame. Time is variable due to ambient temperature. Approximate DTC set time is 10 to 35 minutes. The
following are starting temperature to warm up times to set this DTC: starting temperature -40° C (-40° F) warm
up time 35 minutes, starting temperature -28° C ( -20° F) 25 minutes, starting temperature -6.6° C (20° F) 20
minutes, starting temperature 15.5 ° C (60° F) 10 minutes. When the fault isset, calculated temperature is
substituted for measured temperature, however the DTC is stored only after three consecutive occurrences.

Theory of Operation
The temperature sensor is used to sense the temperature of the transmission fluid. Transmission fluid temperature
can affect shift quality, torque converter operation and when or if some diagnostics are run. A failed temperature
sensor could affect the OBD diagnostics. If a problem occurs in the transmission temperature sensor circuit, trans-
mission temperature will be based on a calculated value.
