The transmission contains fully synthetic automatic transmission fluid (ATF) and is filled for life;
therefore it does not require periodic servicing.
Engine power reaches the transmission via a torque converter with integral converter lock-up
clutch.
The six forward gears and one reverse gear are obtained from a single planetary set, followed by
a double planetary set. This type of gear-set arrangement is commonly known as Lepelletier type
gear-set.
The automatic transmission is electronically controlled. The control system is comprised of the
following elements:
- External transmission control unit (TCU)
- Internal embedded memory module (EMM)
- Input and output speed sensors
- Valve body unit comprised of four on/off solenoid valves and six variable bleed solenoids
- Torque converter
The six speed automatic (M78) transmission
is available in two variants: four wheel drive
and two wheel drive.
