The principle of this modification is to achieve more direct drive from the transmission. By locking the torque converter we can prevent the constant hunting caused by locking and unlocking the converter. It is important we still maintain the factory driveability of the vehicle and this is why we choose to only lock the converter above 80km/h automatically. Below 70km/h the trans can tend to lug as it selects a taller gear and relies on the converter to slip. We have a secondary automatic low speed mode available to lock below this speed and when used in conjunction with the active select mode you can manually hold it down a gear and achieve engine breaking downhills.
We pre program the default speeds which will work out of the box. these speeds are approx:
Low Speed Lock – 35km/h
Low speed un-lock 30km/h.
Auto – Speed Lock – 80km/h
Auto – Speed un-lock – 75km/h
