(B55) No. 10 - Body / 1 M-Ohms or more.

2. Check Shift Solenoid 3 Ground Line.





Measure resistance between Transmission connector receptacle and Transmission case.
Connector & Terminal / Specified Resistance:
(T4) No. 4 - Transmission / 1 Ohms, or less.

3. Check Shift Solenoid 3.





Measure resistance between Transmission connector receptacle's terminals.
Connector & Terminal / Specified Resistance:
(T4) No. 1 - No. 4 / 20 - 32 Ohms.

4. Check output signal emitted from TCM.
a. Connect connectors to TCM and Transmission.
