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

4 The conditions to set this DTC are not present at this time.
Check the gearshift linkage adjustment.
Gear ratio DTC's can be set by problems in the Input and Output Speed Sensor
circuits. If the vehicle passes the clutch test and still sets Gear Ratio DTC(s), check
the Speed Sensors for proper operation.
NOTE: Remove the Starter Relay from the PDC. This will prevent the
vehicle from being started in gear.
Check the Speed Sensor wiring and connectors for good connection, then perform a
wiggle test using the Transmission Simulator, Miller tool #8333 and the FWD
Adapter Cable kit, Miller tool #8333-1.
This DTC can also be set under extreme temperature conditions, this is usually
caused by an internal problem. Verify if the problem is only experienced under
extreme hot or cold conditions.
