A8 CHECK SOLENOID RESISTANCE
Remove the molded leadframe from the main control. REFER to: Shift Solenoids (SS) . Inspect for metallic contamination and clean the solenoid and molded leadframe terminals.
Measure and record the resistance of the suspected solenoid. REFER to: Shift Solenoids (SS) . Compare the recorded value with the chart below.
Solenoid | Ohms |
SSA | 4.8 to 5.6 |
SSB | 4.8 to 5.6 |
SSC | 4.8 to 5.6 |
SSD | 4.8 to 5.6 |
SSE | 17.5 to 18.6 |
LPC solenoid | 4.8 to 5.6 |
TCC solenoid | 4.8 to 5.6 |
Is the solenoid resistance within specification?
Yes | INSTALL a new molded leadframe, REFER to: Shift Solenoids (SS) . CLEAR the DTCs. |
|---|
No | INSTALL a new suspected solenoid which failed the resistance check. REFER to: Shift Solenoids (SS) . CLEAR the transmission adaptive tables and perform the adaptive drive cycle. REFER to: Adaptive Learning Drive Cycle . |

Normal Operation
The TFT sensor is a temperature dependent resistor that is in contact with transmission fluid in the transmission sump area. The PCM monitors the voltage across the TFT sensor, which changes as transmission fluid temperature varies. The PCM uses the TFT sensor signal as an input for its strategy for shifting and TCC operation. The PCM also uses the TFT sensor signal for transmission fault
