P1775-SOLENOID SWITCH VALVE LATCHED IN TCC POSITION Ð
Continued

Symptom:
P1776-SOLENOID SWITCH VALVE LATCHED IN LR POSITION
When Monitored and Set Condition:
P1776-SOLENOID SWITCH VALVE LATCHED IN LR POSITION
When Monitored: Continuously when doing partial or full EMCC (PEMCC or FEMCC).
Set Condition: This DTC will set if the TCM senses the L/R Pressure Switch closing while
performing PEMCC or FEMCC or after two unsuccessful attempts to perform PEMCC or
FEMCC.

1NOTE: Low fluid level can be the cause of many Transmission problems. If
the fluid level is low locate and repair the leak then check and adjust the
fluid level per the Service Information.
NOTE: Always perform diagnostics with a fully charged battery to avoid
false symptoms.
With the DRBIIIt, read the engine DTC's. Check and repair all engine DTC's prior
to performing Transmission Symptom Diagnostics.
With the DRBIIIt, read Transmission DTC's. Record all DTC's and 1 Trip Failures.
NOTE: Diagnose 1 Trip Failures as a fully matured DTC.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Repair as necessary.
Perform the Shift Lever Position Test. If the test does not pass, refer to Symptom test
for P0705 Check Shifter Signal.
For Gear Ratio DTC's, check and record all CVI's.
Most DTC's set on start up but some must be set by driving the vehicle such that all
diagnostic monitors have run.
NOTE: Verify flash level of Transmission Control Module. Some problems
are corrected by software upgrades to the Transmission Control Module.
NOTE: Check for applicable TSB's related to the symptom.
Perform this procedure prior to Symptom diagnosis.All
