This is a wiring problem you have a loose connector at the ECT control module or connector at the transmission,the solution is make proper connection and this is a common problem,that or you have a bad conductor plate in the transmission. Go to the right rear of the engine compartment ensure you connection for the transmission module is all hook up, go to the transmission and ensure nothing at the harness is disconnected

when diagnosing multiple fault codes it can be tricky figuring out whats going on for instance all three of the codes you have are an electrical nature and not mechanical faults in the transmission most likely they share a common power or ground circuit and have lost one or the other also if they do share any circuit and anyone of these are faulty it would generate the other codes. to do an accurate circuit check you should remove the transmission pan so you can check the terminals at the solenoids and switches on the valvebody because the problem could be in the "passthrough" connector

The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light is turned on the computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible faults that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.
