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 the engine DTC’s. Check and repair all engine DTC’s prior
to performing 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 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.

When Monitored:
With the engine running and the TCM has closed the Transmission
Control Relay.
Set Condition:
If battery voltage at TCM Transmission Control Relay Output Sense
circuit is less than 10.0 volts for 15 seconds. *This DTC generally indicates a gradually
falling battery voltage or resistive connections to the TCM.
POSSIBLE CAUSES

Turn the ignition off to the lock position.
Disconnect the TCM harness connector.
Note: Check connectors - Clean/repair as necessary.
Using a 12-volt test light connected to 12-volts, check the ground circuits in the TCM
harness connector.
NOTE: The test light must illuminate brightly. Compare the brightness to
that of a direct connection to the battery.
Does the test light illuminate brightly for all the ground circuits?
All
Yes
→ Go To 5
No
→ Repair the Ground circuit(s) for an open or high resistance.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.
