three: Restricts the transmission to the bottom 3 equipment ratios. Inside of a four-pace automatic transmission, this is frequently utilized to avoid the car shifting in the overdrive ratio.
1 cause why vehicle makers are falling out of love with handbook gearboxes is they Price tag a good deal to develop at any given time when need is diminishing.
