NOTE: To correctly check the transmission fluid level using the
dipstick the transmission fluid must be at operating tempera-
ture. The oil level sensor method of checking the fluid level
compensates for transmission fluid temperature between 60ºC -
104ºC (140ºF - 220ºF). Any temperature below 60ºC (140ºF), or
above 104ºC (220ºF) will result in an Invalid for Display condi-
tion.
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 fil-
ters after the first 8000km (5000 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
40,000km (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 whenev-
er 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.
Manual Check Procedures:
The concept of a cold check is to determine adequate fluid level for safe
operating until hot check can be performed.
• Park the motorhome on a level surface using the service brakes.
• The engine is operated at a low idle. Put the transmission in N (Neutral).
• Apply the parking brake and chock the wheels to prevent the motorhome
from moving.
• Allow the engine to run at idle (500-800 rpm) for one minute.
• Apply the service brakes and shift to D (Drive), then to N (Neutral) and
next to R (Reverse) to fill the system. Finally shift to N (Neutral) and
release the service brakes. Allow the engine to continue to run at idle
(500-800 rpm).
• Remove the dipstick and wipe clean. Reinsert the dipstick fully into the
tube and remove to check fluid level. Repeat this to verify the reading
if needed.
• Safe operating level is anywhere within the COLD CHECK band on the
dipstick. The fluid level is sufficient enough to operate until a HOT
CHECK can be run.
• If the level is not within this band add or drain the fluid as necessary to
bring the level to the middle of the COLD CHECK band.
• Perform the HOT CHECK the first opportunity after reaching normal
operating temperatures (160º-200º F / 71º-93º C).
