GEN V AUTOMATIC TRANSMISSION

The B500 series GEN V is an electronically-
controlled hydraulic auto-shifting six-speed
transmission. This transmission controls all aspects of
the shift function once placed into the desired drive
range. Shift range selections are made with the touch-
pad module located on the side console.
A two-character digital display is located at the top
of automatic transmission shift selector. The left
character of the display, SELECT, designates N, R, or
the highest gear available of the selected forward
range. The right character of the display, MONITOR,
designates the actual gear which is being commanded
by the transmission control module (TCM).
Two-character diagnostic codes can be accessed
using the touch-pad on the pushbutton shift selector.
The MODE button, can be utilized to invoke a
special function that has been programmed into the
TCM. A text indicator on the lower portion of the two
character display illuminates when the MODE function
is activated.
The gear selector should always be in the
NEUTRAL position when the coach is parked
