A delayed fluid level check for transmissions with WTEC III Controls is indicated
by a “—” in the display window followed by a numerical countdown. The
countdowns, starting at 8, indicates the time remaining in the two minutes setting
period.
The indication of a delayed fluid level check for Allison 4
th
Generation Controls is
a flashing display under SELECT and a digit countdown from 8 to 1 under
MONITOR.
• Correct Fluid Level—“oL” is displayed (“oL” represents “Fluid (Oil)
Level Check Mode”), followed by “oK”. The “oK” display indicates the
fluid is within the correct fluid level zone. The sensor display and the
transmission dipstick may not agree exactly because the oil level sensor
compensates for fluid temperature.
