Gear Logi C Control - 5-Speed Automatic - Honda Accord Euro Technical Product Book

The Honda Accord Euro
shifting and gear hold. To heighten control and driver involvement, the shift logic in manual mode
delivers quicker, firmer shifts than in fully automatic mode.
To help protect the engine and drivetrain from damage, an array of preventative features are active when
the transmission is in manual mode. In second, third and fourth, the logic changes, and the transmission
ECU cuts off fuel flow to the engine if there is a possibility of over revving.
In the rare situation where the fuel cut-off alone is unable to prevent engine over revving (as could
happen on a steep downhill) the transmission will change up to prevent engine damage. And finally, when
changing down, the transmission won't execute a driver-commanded downshift that would send the
engine beyond the redline in the lower gear.
The system will also automatically select first gear as the Accord Euro comes to a stop, to prevent pulling
away in a high gear.
A further enhancement of the latest automatic gearbox is a kick-down 'click' system. Instead of a vague
stab of the pedal to initiate the kick-down mechanism, the driver is given a clear indication of the point in
the accelerator pedal's travel at which the gear change will operate - once a 'click' is sensed, a further slight
movement of the foot will initiate the down change.
A graphic of the shift lever position is provided in the centre of the rev counter dial for added
convenience.
The use of low friction clutches for all gears and the super-thin, highly efficient torque converter in the 5-
speed automatic transmission contributes to the Accord Euro's excellent fuel economy.
Gear Logi c Control – 5-speed automatic
When in automatic mode, the transmission incorporates an advanced Gear Logic Control, which works to
reduce gear 'hunting' and unnecessary changes.
