Transaxle controller monitors transaxle for electrical or internal problems. If battery voltage is lost, or transaxle controller senses a transaxle failure and fault code is set, transaxle enters and stays in limp-in mode until failure is repaired. In limp-in mode, only Park, Neutral, Reverse and 2nd gears function. Transaxle will not upshift or downshift. Vehicle can be operated, but performance will be reduced.
Solenoid assembly may also be referred to as solenoid pack.
Solenoid assembly is controlled by the transaxle controller. Transaxle controller provides voltage to EATX relay, causing contacts to close, supplying voltage to solenoid assembly.
Solenoid assembly, consisting of 4 electric solenoids, controls transaxle hydraulic circuits. Transaxle controller completes ground circuit, operating solenoid for proper hydraulic circuit control. Low-reverse, overdrive and 2-4 pressure switches are located in the solenoid assembly. Pressure switches send input information to transaxle controller, indicating whether circuit hydraulic pressure exists. Transaxle controller uses this information to verify solenoid assembly operation.
