This automatic gearbox is a four-speed unit with electronic control of gear selection, shift quality and torque converter ock-up. Selections on the selector lever assembly are transmitted to the gearbox by a selector cable. A gear position switch on the gearbox transmits the gear selection to an Electronic Automatic Transmission (EAT) ECU, which outputs the appropriate control signals to an electro-hydraulic valve block in the gearbox. A mode switch enables the driver to change the control mode of the EAT ECU. The EAT ECU operates warning lamps in the instrument pack to indicate the control mode and system status.
The gearbox features a pressure lubrication system and is cooled by pumping the lubricant through an oil cooler.
On NAS market vehicles from 03 model year, the ZF 4HP24 transmission unit is introduced for use with the 4.6-litre V8 engine.
