dirveability issue. The DTC is also intended to alert the technician to determine if a cooling system malfunction has
occurred or if an additional transmission air to oil cooler is needed to support the customers driving behavior.
When Monitored:
Whenever the engine is running.
Set Condition:
Immediately after a Overheat shift schedule is activated when the Transmission temperature exceeds 127° C
or 260° F.

Diagnostic Test
1.HIGH TEMPERATURE OPERATION
This DTC is an informational DTC designed to aid the Technician in diagnosing shift quality complaints.
This DTC indicates that the transmission has been operating in the
Overheatshift schedule which may generate
a customer complaint.
The customer driving patterns may indicate the need for an additional transmission oil cooler.
Verify proper Engine cooling system operation which would affect proper transmission operation.
Verify proper torque converter clutch operation.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.
If there are no possible causes remaining, view repair.
Repair
Repair the cause of transmission overheating. Refer to the Service Information for the proper repair
procedure. Make sure to check for any Service Bulletins pertaining to thisproblem.

P0740-TCC OUT OF RANGE
For a complete wiring diagramRefer to Section 8W
When Monitored:
During Electronically Modulated Converter Clutch (EMCC) Operation.
Set Condition:
Transmission must be in EMCC, with input speed greater than 1750 RPM. TCC-LR Solenoid achieves the
maximum duty cycle and can not pull engine speed within 60 RPM of input speed. Also when the transmission
is in FEMCC and the engine slips TCC less than 100 RPM for 10 seconds. This DTCcantakeuptofive
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
When in 2nd, 2nd Prime, 3rd, 4th or 5th gear, the torque converter clutch (TCC) can be engaged when certain
conditions are met. The TCC piston is electronically modulated by increasing the duty cycle of the LR Solenoid until
the torque converter slip difference (difference between engine and transmission input speed) is within 60 RPM.
Then the LR solenoid is fully energized(FEMCC – 100% duty cycle). Torque converter slip is monitored in FEMCC
to ensure adequate clutch capacity.

49° C or 120° F.
Perform the following steps 3 times.
Drive the vehicle to the speed of at least 88 Kmh or 55 mph.
Allow 4th or 5th gear to engage for at least 10 seconds.
Close the throttle.
Tip back into the throttle until the TPS angle is between 25 and 29 degrees.

21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
Line pressure is measured by the Line Pressure Sensor (LPS) and regulationis achieved by changing the duty
cycle of the Pressure Control Solenoid (PCS) controlled by the Transmission Control System. (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 both the engine and transmission.
The Transmission Control System calculates torque input to the transmission and uses it as the primary input to the
desired line pressure calculation. This is called Torque Based Line Pressure. In addition, the line pressure is set to
a preset level 827 or 931kPa (120 or 135 psi) during shifts and in Park and Neutral to ensure consistent shift qual-
ity. The desired line pressure is continuously being compared to the actual line pressure. If the actual line pressure
is consistently lower than the target while driving, the line pressure lowDTC P0868 will set.
