NOTE
Not all bands are adjustable. Always check the manufacturer's service manual before
any servicing of the transmission.
2.5.1.3 Fluid Replacement
Perform fluid replacement according to the manufacturer's recommendations. These
recommendations vary considerably for different makes and models. Before you change
automatic transmission fluid, always read the service manual first.
Service intervals depend on the type of use the vehicle receives. In the NCF, because
of the operating environment, more than a few of the vehicles are subjected to severe
service. Severe service includes the following: hot and dusty conditions, constant stop-
and-go driving (taxi service), trailer towing, constant heavy hauling, and around-the-
clock operations (contingency). Any CESE operating in these conditions should have its
automatic transmission fluid and filter changed on a regular schedule, based on the
manufacturer's specifications for severe service. Ensure the vehicle is on level ground
or a lift, and let the oil drain into a proper catchment device.
The draining of the transmission can be accomplished in one of the following three
ways:
1. Removing the drain plug
2. Loosening the dipstick tube
3. Removing the oil pan
