Transmission oil will be extremely hot when drained. Do not come in contact with hot oil
to avoid severe burns. If burned with hot oil, seek medical attention immediately.
Transmission should be between 160 to 200 degrees F (71 to 93 degrees C) at time when
oil is drained. Transmission will not drain completely if not at proper temperature. Read
transmission temperature gage in cab to check temperature.
Truck should be serviced on level surface to ensure oil level can be checked correctly and
that all oil possible is drained.
