GENERAL DESCRIPTION

E85EDBFC

The Automatic transmission changes the gear position of the transmission by utilizing a combination of clutches and
brakes, which are controlled by solenoid valves. This automatic transmission consists of a: LR (Low and Reverse Brake),
2ND (2nd Brake), UD (Under Drive Clutch), OD (Over Drive Clutch), REV (Reverse Clutch), and a RED (Reduction Brake,
only for 5 speed transmissions).
The RED Brake is engaged in the 1st, 2nd, 3rd gear and reverse gear positions.

DTC DESCRIPTION

E74450E8

The TCM checks the Reduction Control Signal by monitoring the feedback signal from the solenoid valve drive circuit. If
an unexpected signal is monitored (for example, high voltage is detected when low voltage is expected, or low voltage
is detected when high voltage is expected), the TCM judges that the Reduction control solenoid circuit is malfunctioning
and sets this code.
