DTC P0605 INTERNAL TRANS CONTROLLER

DTCs will set if an internal TCM malfunction occurs.
Possible Cause
Internal TCM failure.

DTC P0700: EATX CONTROLLER DTC PRESENT
Monitored & Set Conditions
Electronic Automatic Transaxle (EATX) controller is monitored for DTCs when ignition is on and engine is running. EATX controller may also be referred to as Transmission Control Module (TCM). DTC will set in Powertrain Control Module (PCM) memory if any DTC is set in the TCM memory. Possible cause for DTC to set is: TCM DTC is present in PCM.
Testing
Turn ignition on. Using scan tool, read DTCs. If DTC P0700: EATX CONTROLLER DTC PRESENT is set, this DTC indicates a transmission DTC has previously been set. A DTC may not currently be present in TCM if a transmission repair was performed. If after reading transmission DTCs there are no DTCs in TCM, this DTC may be erased from PCM.

DTC P0845: 2-4 HYDRAULIC PRESSURE SWITCH CIRCUIT
Circuit Description
DTC P0845 will set if an error occurs in 2-4 pressure switch. TCM momentarily turns on element pressure to 2-4 clutch circuit to identify that pressure switch closes. If switch does not close after first test, switch is tested again. If switch does not close on second test, DTC will set. MIL illuminates and transmission system defaults to limp-in mode.
Possible Cause
Low battery voltage.
DTC P0944 (Loss Of Prime) set.
Transmission control relay output circuit open.
Low transmission fluid level.
2-4 pressure switch sense circuit short to ground.
2-4 pressure switch sense circuit short to voltage.
2-4 pressure switch sense circuit open.
2-4 solenoid failure.
