Transmission general data
The
2ML70 gearbox is a 4-speed rear drive which can be configured in a two or four
wheel drive application. The secret of this transmission lies in combination of
2 electric motors inside the transmission, which serve not only for driving the
car under certain conditions, but also for starting the engine. The 2ML70
transmission has several important advantages when compared to its gasoline
counterparts: reduced fuel consumption, improved performance characteristics,
reduced amount of toxic emissions.
| Number of gears | Transmission Type | Drive | Torque (Nm) | ATF (full capacity) L | ATF (change) L | ATF type |
|---|
| 4 | Hybrid System | RWD | 515 | 12.3 | 10.8 | Dexron VI |
This
transmission doesn’t have a torque converter. It is equipped with stop/start
technology and therefore has a 12 volt auxiliary pump to keep the 1-2 clutch
primed any time the engine shuts down. The design of 2ML70 also includes 3
planetary gear sets, 2 rotating clutch packs and 2 fixed clutch packs. The
gearbox functioning is controlled by a Transmission Control Module (TCM) which
is located inside the transmission and the hybrid systems operation is
controlled by the Hybrid Control Processor (HCP) located under the hood.
