2. A command to shift will only be acted upon if the TCCU is
reading a valid code at the time the command to shift is
made.
3. After a shift has started, the TCCU will power the shift motor
until the code for the requested position is read. If an invalid
code is read, the TCCU will go into a default mode.
4. During a shift attempt, the shift motor will be energized for a
maximum of 5 seconds.
