I-shift gear changing

I-shift get information from vehicle control unit, ABS (EBS) control unit and air suspention control unit and engine control unit. if wrong information comes from ABS control unit I-shift cant get second signal about vehicle speed, but main signal is from vehicle control unit.
If one of thees signal is mising about vehicle speed I-shift wont ride well

 

all sensors are important, but i-shift is smarter then astronic ore gear tronic, so it may work with one bad abs sensor

 

sometimes when you dont come to a complete stop my ishift gets confused and doesnt want to upshift so i help it manualy if im still in the lower gears i back off it and pop it in neutral for a coulple seconds and then back into drive and it seems to reset the gearselecter ecu and it goes back to performing normally i love this tranny its the smartest tranny ive ever operated
