For the Transmission circuit diagram (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - SCHEMATICS AND DIAGRAMS)
For a complete wiring diagram Refer to Section 8W.
Every 7 ms when doing PEMCC or FEMCC.
Must be in partial or full EMCC. The DTC is set if L/R pressure is detected high for the fourth time.
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - DIAGNOSIS AND TESTING).
The Solenoid Switch Valve, an internal, hydraulically operated valve, controls the direction of the transmission fluid when the L/R solenoid is energized. When the solenoid switch valve is in the downshifted position and the L/R solenoid is energized, fluid is directed to the L/R element for 1st gear. When the solenoid switch valve is In the up-shifted position (2nd, 3rd, and 4th gear) and the L/R solenoid is energized, fluid is directed into the Lockup Switch Valve which controls the Torque Converter Clutch. When doing PEMCC or FEMCC, the L/R pressure switch should indicate no pressure if the solenoid switch valve is in the LU position. If the L/R pressure switch indicates pressure for some time while in partial or full EMCC, the EMCC operation is aborted and momentarily inhibited to avoid accidental application of the L/R clutch. EMCC is attempted again when there is no L/R pressure. The fourth detection of L/R pressure while in PEMCC or FEMCC will result in setting the DTC.Torque converter EMCC operation inhibited. MIL on after 5 min. of substituted operation.
Is the DTC P0841 present also?
Does the DTC EVENT DATA show a TRS Code of TR2?
NOTE: This counter only applies to the last DTC set.
Is the status Active or is the STARTS SINCE SET counter 2 or less for this DTC?
CAUTION: Removal of the Starter Relay is to prevent a Transmission, NO RESPONSE, condition and disable the starter.
Did the Pressure Switch state change from open to closed when the test button was pressed?
NOTE: This DTC may be caused by debris lodged in the Transmission Solenoid Switch Valve bore. If debris is found, clean the valve body and reassemble the transmission per the Service Information.
Did the DTC P1776 reset?
NOTE: Check connectors - Clean/repair as necessary.
CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller tool #8815 to perform diagnosis.
Is the resistance above 5.0 ohms?
Is the resistance below 5.0 ohms?
Is the voltage above 0.5 volts?
Are there 2nd gear launches and/or no TCC engagement?
