Manual transmission went by way of a number of progress and variants as vehicle manufactures experimented with design and style.
The locking sequences from the epicyclic equipment practice are achieved by hydraulic force working brake bands or multi-plate clutches.
As vehicle pace increases, the strain from the governor builds. This forces the shift valve about until finally the 1st gear circuit is closed, and the 2nd equipment circuit opens.
