WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and reproductive harm. Always use in combination with a momentary contact switch.Attached mounting bracket with 2 x 9/32? diameter mounting holes on 2 ? centers.Inlet port normally closed- only for alternating use.Must be installed vertically with air inlet port facing upward.While the shift solenoid not receives power, the plunger remains closed. That puts pressure on the clutches and bands originating that gear shifts.

When the shift solenoid is activated, the plunger will open some valves to permit the entry of transmission air flow. Those sensors indicate when transmission should shift gears according on speed. Through the wire, the plunger makes contact with the engine sensors through electronic signals. Shift solenoids have a spring loaded plunger covered with a coil of wire. In an automatic transmission system, a shift solenoid is an electronically activated element which opens and closes some valves to control the transmission fluid flow from the gear shifts.
