Symptom:
P0992-2-4/OD HYDRAULIC PRESSURE TEST FAILURE
When Monitored and Set Condition:
P0992-2-4/OD HYDRAULIC PRESSURE TEST FAILURE
When Monitored:
In any forward gear with engine speed above 1000 RPM shortly after
a shift and every minute thereafter.
Set Condition:
After a shift into a forward gear, with engine speed >1000 RPM, the PCM
momentarily turns on element pressure to the clutch circuits that don’t have pressure to
identify the correct pressure switch closes. If the pressure switch does not close 2 times, the
DTC sets.

NOTE: 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 DRBIII
t, read Engine DTC’s. Check and repair all Engine DTC’s prior to
performing any transmission symptom diagnostics.
With the DRBIII
t, 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 P0706 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 Powertrain Control Module. Some problems are
corrected by software upgrades to the Transmission and Engine software.
NOTE: Check for applicable TSB’s related to the problem.
Perform this procedure prior to Symptom diagnosis.

NOTE: The vehicle must be driven to set this DTC. The transmission must be
warm or hot with the Engine RPM above 1000 RPM.
This DTC is an indication of both the 2/4 and the O/D Hydraulic Pressure Switch
DTCs present.
Perform diagnostics for both P0870 and P0845 to determine which switch is the cause
of the DTC.
With the DRBIII
t, check the EATX EVENT DATA to help identify the conditions in
which the DTC was set.
If there are no possible causes remaining, view repair.
