Transmission Lubricating Fluid; Chassis Information - Monaco 2002 Diplomat Service Manual

• The delayed fluid level check will display in the digital display
window. The display will be one character at a time. The "o,L"
represents oil level check mode. This will be followed with fluid
level indication readings. The "o,K" indicates a correct fluid
level. Reading between the OLS and the dipstick may not agree
because the OLS compensates for fluid temperatures. Abnormal
indications of the OLS will be "Lo" representing a low fluid
level, "HI" for a high fluid level or "oL" for invalid information
and system problems. All indications will be followed by numer-
ic values. The "Lo" and "HI" followed by the numeric value rep-
resents the quarts of fluid required for the system. The invalid
code numbers represent specific symptoms.
Common Oil Level Fault Codes:
• 0,5 settling time too short.
• 5,0 speed RPM too low.
• 5,9 speed RPM too high.
• 7,0 sump temperature too low.
• 7,9 sump temperature too high.
• 9,5 OLS FAILURE.
NOTE: Exit the fluid level display by pressing any range
button on the keypad.
NOTE: To correctly check the transmission fluid level
using the dipstick, the transmission fluid must be at operat-
ing temperature. The oil level sensor method of checking
the fluid level compensates for transmission fluid tempera-
ture between 60º C - 104º C (140º F - 220º F). Any tempera-
ture below 60º C (140º F), or above 104º C (220º F), will
result in an Invalid for Display condition.
Any fluid meeting Dexron-III specifications are acceptable for use in the
transmission. Transmission performance, reliability and durability are important
influences in the type of fluids used. Change the fluid internal filters after
the first 8,000 km (5,000 miles). The dipstick/oil fill is located between the
engine and transmission underneath the engine access door in the bedroom.
Change the transmission fluid and internal filters every 40,000 km (25,000
miles) or 18 months, whichever occurs first.
Fluid and Internal Filters Change Interval Recommendations:
The fluid and internal filters may require changing earlier depending on
the severity of operating conditions. The fluid must also be changed whenever
there is evidence of dirt or high temperature conditions as indicated by
discoloration, strong odor or fluid analysis. Local conditions, severity of
operation or duty cycle will dictate more or less frequent service intervals.
