Description & Operation: Notes
Input signals from sensors are sent to the PCM. The PCM can determine when the time and conditions are right for a shift or converter clutch application.
On F4E/4EAT - Type-F transaxle 4 electronic solenoids accomplish these functions; 3 On/Off solenoids for shifting and one On/Off solenoid for torque converter clutch control.
The PCM has built-in self-diagnosis, fail-safe code and warning code display for the main input sensors and solenoid valves.
NOTE:
In addition to transmission fault codes, engine-related fault codes may be output during QUICK TEST procedure. These fault codes pertain to engine performance and must be repaired first as engine performance will greatly affect transmission operation. For information and testing procedures of engine-related fault codes and components, see appropriate TESTS W/CODES
article in ENGINE PERFORMANCE section.
