Fahad sab mechanic is right,
Take a look,
ATF temperature sensor converts ATF temperature to an electrical resistance value. Based on the
resistance, the ECM determines the ATF temperature, and the ECM detects an open or short in the ATF temperature circuit.
If the resistance value of the ATF temperature is less than 79 Ω*1 or more than 156 kΩ*2,
the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will illuminate the MIL and store the DTC.

The Torque Converter Clutch TCC release switch is part of the automatic Transmission Fluid Pressure TFP manual valve position switch. The TFP manual valve position switch is mounted to the transmission valve body. The TCC release switch is a normally-closed switch. When the TCC is released, TCC release fluid pressure opens the TCC release switch which opens the TCC release pressure circuit. When the voltage on the circuit is high (switch open), the Powertrain Control Module (PCM) recognizes that the TCC is no longer engaged.
