Check the connection between the TR sensor and the manual control valve. REFER to: Transmission .
Inspect the molded leadframe for metallic contamination, REFER to: Shift Solenoids (SS) .
Is the TR sensor connected to the manual control valve shaft?
Is the TR sensor connected to the manual control valve shaft?
Yes | INSTALL a new TR sensor. REFER to: Shift Solenoids (SS) . |
|---|
No | CONNECT the TR sensor to the manual control valve, REFER to: Shift Solenoids (SS) . CLEAN any debris from the molded leadframe. RUN the KOEO self-test. If DTCs return, INSTALL a new TR sensor. REFER to: Shift Solenoids (SS) . |

Normal Operation
The TSS sensor is a Hall-effect type sensor that provides a signal to the PCM that changes in frequency as the rotating speed of the forward (1, 2, 3, 4) clutch cylinder varies. The PCM compares the TSS sensor signal with the engine speed information to determine the amount of slip occurring in the torque converter. The PCM also compares the TSS sensor signal with the OSS sensor signal to determine the gear ratio provided by the rear planetary gearset. The PCM uses the TSS sensor signal as an input for its strategies for shifts and TCC operation. The PCM also uses the TSS sensor signal for transmission fault detection and diagnostics.
