P0897-TRANSMISSION FLUID DETERIORATED
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Each transition from full EMCC to partial EMCC for A/C bump prevention.
Set Condition:
DTC set if 20 occurrences of a turbine acceleration sum. Fault Set Time: 20 transitions from full EMCC to
partial EMCC. Transmission will not use partial EMCC. Established for A/Cbump prevention.
Possible Causes
WORN OUT/ BURNT TRANSAXLE FLUID
Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
To prevent a bump due to A/C clutch engagement, a temporary torque converter partial EMCC condition is estab-
lished prior to A/C clutch engagement. A message is received over the bus indicating that A/C clutch engagement
is imminent. Partial EMCC is then established and a reply message,
OK to engage A/C clutchis sent via the bus.
Partial EMCC will be held for 450 ms before returning to full EMCC. During the transition from full to partial EMCC,
a turbine acceleration sum is calculated, if this value exceeds a threshold value for several transitions, degraded
transmission fluid is indicated.
Diagnostic Test
1.WORN OUT/ BURNT TRANSMISSION FLUID
Turn the ignition off to the lock position.
Flush the Transmission Oil Cooler and lines, replace the Transmission OilFilter, refill with new Transmission Fluid,
start the engine, and adjust the fluid per the Service Information.
NOTE: The Transmission Cooler must be flushed before proceeding.
Allow the engine to idle for 10 minutes, in Park.
Turn the ignition off to the lock position.
Again, flush the Transmission Oil Cooler and lines, replace the Transmission Oil Filter, refill with new Transmission
Fluid, start the engine, and adjust the fluid per the Service Information.
With the scan tool, perform a Battery Disconnect.
NOTE: The Battery Disconnect must be done to re-enable EMCC during an A/C Clutch engagement.
NOTE: The vehicle may exhibit intermittent shudder during the first few hundred miles. The new Transmis-
sion Fluid will gradually penetrate the Torque Convertor Clutch frictionmaterial and the shudder should
disappear.
Erase the DTC and return the vehicle to the customer.
Did the DTC reset and/or does the vehicle still shudder after a few thousandmiles?
Ye s>>
Replace the Torque Converter per the Service Information.

When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
This DTC will set when the monitored Line Pressure Sensor voltage is less than or equal to 0.35 volts for 0.18
seconds.

LINE PRESSURE SENSOR
POWERTRAIN CONTROL MODULE
Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
Line pressure is electronically controlled by the Transmission Control System and is measured by the Line Pressure
Sensor (LPS). The desired line pressure is continuously being compared tothe actual line pressure and is regulated
by electronically changing the dutycycle of the Pressure Control Solenoid (PCS). (5% duty cycle = solenoid off =
max line pressure, 62% duty cycle =solenoid on = min line pressure).
The Transmission Control System calculates the desired line pressure based on inputs from the transmission and
engine. A calculated torque input to the transmission is used as the primary input of the desired line pressure cal-
culation and is called Torque Based Line Pressure. In addition, the line pressure is set to a preset level 827 to 931
kPa (120 to 135 PSI) during shifts and in Park and Neutral to ensure consistent shift quality.
The monitored Line Pressure Sensor voltage should always be between 0.35 and 4.75 volts. Any monitored volt-
ages outside these parameters indicate an Line Pressure Sensor or wiring problem and will cause either DTC
P0934 or P0935 to set.
Diagnostic Test
1.CHECK IF DTC IS CURRENT
