Abstract
A method and apparatus for controllably shifting into a lower gear of a manual transmission is disclosed. A maximum downshift limit value is established and stored in a memory. The downshift speed variable of the manual transmission is set equal to the maximum downshift limit value in response to a valid control condition being determined. The manual transmission is controllably shifted into a lower gear when the engine speed is less than or equal to the downshift speed variable.
