6
Turn the ignition off to the lock position.
Disconnect the TCM harness connector.
Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance between ground and the L/R Pressure Switch Sense circuit.
Is the resistance below 5.0 ohms?
All
Yes
→ Repair the L/R Pressure Switch Sense circuit for a short to
ground.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.
No
→ Go To 7
7
Turn the ignition off to the lock position.
Disconnect the TCM harness connector.
Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.
Remove the Transmission Control Relay.
Note: Check connectors - Clean/repair as necessary.
Connect a jumper wire between the Fused B+ circuit and the Transmission Control
Relay Output circuit in the Transmission Control Relay connector.
Ignition on, engine not running.
Measure the voltage of the L/R Pressure Switch Sense circuit.
Is the voltage above 0.5 volts?
All
Yes
→ Repair the L/R Pressure Switch Sense circuit for a short to
voltage.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.
No
→ Go To 8

Turn the ignition off to the lock position.
Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.
Remove the Transmission Control Relay.
Note: Check connectors - Clean/repair as necessary.
Connect a jumper wire between the Fused B+ circuit and the Transmission Control
Relay Output circuit in the Transmission Control Relay connector.
Using a 12-volt test light connected to ground, check the Transmission Control Relay
Output circuit.
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?
All
Yes
→ Go To 9
No
→ Repair the Transmission Control Relay Output circuit for an open
or high resistance.
Perform 41TE TRANSMISSION VERIFICATION TEST - VER 1.

Using the schematics as a guide, inspect the wiring and connectors. Repair as
necessary. Pay particular attention to all power and ground circuits.
If there are no possible causes remaining, view repair.
