Is the STARTS SINCE SET counter 2 or less?
All
Yes → Go To 4
No → Go To 8
4 Turn the ignition off to the lock position.
Remove the Starter Relay.
CAUTION: Removal of the Starter Relay is to prevent a Transmission, NO
RESPONSE, condition and disable the starter.
Install the Transmission Simulator, Miller tool #8333 and the Electronic Transmis-
sion Adapter kit 8333-1A.
Note: Check connectors - Clean/repair as necessary.
Ignition on, engine not running.
With the Transmission Simulator, turn the Input/Output switch to OFF.
With the DRBIIIt, monitor the TRANS TEMP VOLTS while turning the Thermistor
Voltage switch to all three positions on the Transmission Simulator.
Compare the DRBIIIt readings with the numbers listed on the Transmission
Simulator.
Do the readings on the Transmission Simulator match the DRBIIIt readings ± 0.2
volts?
All
Yes → Go To 5
No → Go To 6
5 If there are no possible causes remaining, view repair. All
Repair
Replace Transmission Solenoid/TRS assembly per the Service
Information.
Perform 41TE (NGC) TRANSMISSION VERIFICATION TEST -

THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance between ground and the Transmission Temperature Sensor
Signal circuit.
Is the resistance below 5.0 ohms?
All
Yes → Repair the Transmission Temperature Sensor Signal circuit for a
short to ground.
Perform 41TE (NGC) TRANSMISSION VERIFICATION TEST -
VER 1.
No → Go To 7
