NOTE: If it takes some amount of time until the transmission
fluid reaches its normal operating temperature [70
−
80
°
C
(158
−

°
F)], check the transmission fluid level by refer-
ring to the left diagram.
13.When the transmission fluid is less than the specified level,
add transmission fluid.
When the transmission fluid is greater than the specified
level, drain the excess fluid through the drain plug to adjust
the transmission fluid to the specified level.
14.Firmly insert the dipstick into the oil filler tube.
FLUSHING COOLERS AND TUBES
M1231104800171
Required Special Tool:
• MB995062: Flushing Tool
WARNING
•
Wear protective eyewear that meets the require-
ments of and ANSI Z87.1
−
1968 and OSHA. Wear
standard industrial rubber gloves.
•
Keep lighted cigarettes, sparks, flames, and other
ignition sources away from the area to prevent the
ignition of combustible liquids and gases. Keep a
class B fire extinguisher in the area where the
flushing tool will be used. Keep the area well venti-
lated. Do not let flushing solvent come in contact
with eyes or skin. If it does, flush with water for 15
to 20 seconds. Remove contaminated clothing and
wash affected skin with soap and water. Seek med-
ical attention.
When a transmission failure has contaminated the transmission
fluid, the oil cooler(s) must be flushed. The cooler by-pass
valve in the transmission must also be replaced. The torque
converter must also be replaced with an exchange unit. This
will ensure that metal particles or sludged transmission fluid are
not later transferred back into the reconditioned (or replaced)
transmission. There are two different procedures for flushing
coolers and lines. The recommended procedure is to use spe-
cial tool MB995062 Flushing Tool. The other procedure is to
use a hand suction gun and mineral spirits.
1. Remove the cover plate filler plug on special tool
MB995062. Fill the reservoir 1/2 to 3/4 full with fresh flushing
solution. Flushing solvents are petroleum based solutions
generally used to clean transmission components. Do not
use solvents containing acids, water, gasoline, or any other
corrosive liquids.
2. Reinstall the filler plug on special tool MB995062.
3. Verify that the pump power switch is turned "OFF." Connect
the red alligator clip to the positive battery terminal. Connect
the black alligator clip to a good ground.
