Shift Solenoids

Use the following Holden Shift chart for questions below.


Shift Solenoids


Which solenoids are "on" when this vehicle is shifted into drive and starts out in first gear?
Both Solenoids are on on when this vehicle is in 1st gear.


Which solenoids are "on" when this vehicle automatically shifts into second gear?
When the vehicle switches to second gear, the second solenoid is on


Which solenoids are "on" when this vehicle automatically shifts into third gear?
No solenoids are on when this vehicle is in 3rd gear





Which solenoids are "on" when this vehicle automatically shifts into fourth gear?

Describe what would happen if none of these solenoids came "on". Could the vehicle drive? What gear would it be in? How fast could it go? Could it have the power to climb a hill?


If all the solenoids were off in this vehicle, the only gears this vehicle could use would be 3rd gear. That is because in 3rd gear this transmission does not need any solenoids on. The vehicle will be slow and sluggish at start off and could only use third gear. As for climbing a hill, the vehicle could drive up it if the vehicle had a running start.
