A transmission solenoid or cylinoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied by the transmission computer or controller.
The delay box acts as an on-board timer for the transbrake (from transmission brake). A transbrake is a part of a racing automatic transmission used in drag racing, and are not found in manual transmissions. The electronic timer is packaged in a metal enclosure when sold to drag racers, thus the slang term delay box.
The C4 was designed to be a lighter and simpler replacement for the original Ford-O-Matic two speed transmission being used in smaller, less powerful cars. Ford used the term "SelectShift" because in the first C4's, placing the gear selector in D2 forced the transmission to start in second gear and then shift to third gear.
In drag racing, a transbrake is a mechanism that selectively places the transmission in a forward and reverse gear simultaneously. This allows the engine to create full power without transmitting that power through the driveline, allowing the car to stay in one place.
The solenoid can be useful for positioning, stopping mid-stroke, or for low velocity actuation; especially in a closed loop control system. A uni-directional solenoid would actuate against an opposing force or a dual solenoid system would be self cycling. The proportional concept is more fully described in SAE publication 860759 (1986).

Word on the mountain has it that Lindsey Vonn is still fast through a downhill course, even at 40 years old. On a frigid Friday morning, Vonn darted through the shadows along the speed course at ...
The C4 Corvette represented a clean break from the Zora Arkus-Duntov-designed C3, with a completely new chassis and sleeker, more modern but still evolutionary styling.It was the work of a team under chief Corvette designer Dave McLellan, who'd taken over from Duntov in 1975 — under the design direction of Irv Rybicki.
