Borg Warner 35 gearbox

Summary
The Borg Warner 35 is a fully hydraulically controlled transmission which has three forward ratios and reverse.

In a Borg Warner Model 35 transmission there are three forward gear ratios and reverse

The selector lever works in a quadrant which has six stations,

They denote Park, Reverse, Neutral, Drive, Second and First.

When the transmission is placed in "D" or Drive range, the vehicle will move off in first gear and will change to second and then to third gear in accordance with road speed and engine load.

Downshifts from third to second and from second to first are also fully automatic, unless the driver resorts to kickdown

Kickdown changes are useful when short bursts of acceleration are required and occur at higher speeds than automatic changes.

Automatic upshifts take place immediately accelerator pressure is eased off following a kickdown.
