Mode Button
The mode button is located on the keypad pushbutton shift selector. The mode button can
be pressed at any time after engine start to activate the alternate shift schedule. There are two shift
schedules, a primary and a secondary.
The primary shift schedule is normally used each time the vehicle is started and is specified
in such a way to accommodate
“NORMAL”
vehicle operation. This shift schedule is also known
as
“PERFORMANCE”
mode .
The secondary shift schedule is an alternate shift schedule that the TCM only uses upon
request. This shift schedule is also known as
“ECONOMY”
mode.
“ECONOMY”
mode will allow the transmission to make shift changes at a lower engine
RPM, thus making it possible to get better fuel mileage . Factors such as terrain, driving habits,
vehicle weight and towing will still have an impact on mileage.
Fluid Level Check
Use the transmission dipstick for best results in checking the transmission fluid level. The transmission will not
reach operating temperature until the coach has been driven for at least 15 miles. Therefore, it may be best to
check transmission fluid level at the end of your driving day.
Transmissions do not consume fluid. If your transmission shows to be low of fluid, it should be inspected for
leaks.
The dipstick is marked with temperature bands for a COLD and HOT fluid level check. The fluid check
marked COLD is designed to allow the fluid level to be checked from 61-140°F (16-60°C). The fluid check
marked HOT is designed to allow the fluid level to be checked form 160-220°F (71-104°C).
Check the transmission fluid level with the following steps
(HOT CHECK PROCEDURE):
Conditions that must be met for checking transmission fluid with the dipstick:
• Be sure transmission is at operating temperature (104° to 220° F)
• Vehicle is parked on level ground with the parking brake is set
• Transmission in neutral and park brake applied
• Engine is at low idle
• Wait until vehicle has been stationary for two minutes
• With the engine running, remove the dipstick from the tube and wipe the dipstick clean
•
Insert the dipstick into the tube and remove. Check the fluid level reading. Repeat the check
procedure to verify the reading.
