2. Remove dipstick and then remove drain plug. Drain oil from transmission into a suitable
container.

Metal Particles - A few small particles are normal. Larger metal chips are an early sign
of transmission failure which may mean transmission should be disassembled and in-
spected for internal damage.
Rubber Particles - Indication of cooler hose wear. Hoses should be inspected for
cracks or fraying. Replace damaged hoses.
