The A340E is a 4−speed, Electronic Controlled Transmission (hereafter called ECT) developed for use with high−performance engine. A lock−up mechanism is built into the torque converter.
The A340F automatic transmission is a 4−speed automatic transmission with mechanically controlled 4WD transfer, developed with the aim of producing an easy−driving 4WD vehicle. The transmission section has fundamentally the same construction as the A340E automatic transmission.
The A340H automatic transmission is a 4−speed automatic transmission with electronically controlled 4Wd transfer, developed with the aim of producing an easy driving 4WD vehicle.
The transfer section consists of planetary gears, hydraulic clutches and hydraulic brake. The operation of these is fully controlled by the Engine ECT ECU.
The A340E, A340F and A340H automatic transmissions are mainly composed of the torque converter, the overdrive (hereafter called O/D) planetary gear unit, 3−speed planetary gear unit, the hydraulic control system and the electronic control system.
