GENERAL DESCRIPTION

E9004129

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 LR Brake is engaged in the 1st gear and reverse gear positions.

DTC DESCRIPTION

E700E62E

The TCM checks the Low and Reverse 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 Low and Reverse control solenoid circuit is
malfunctioning and sets this code.
