level
i n t h e automatic
transmission
should be checked when performing other underhood
services. Operation w i t h a n improper f l u i d level w i l l
greatly reduce t h e life of the transmission and f l u i d .
W h e n t h e f l u i d level is checked, especially o n vehi-
cles operated under conditions of severe service, t h e
condition o f t h e f l u i d should be observed. I f severe
d a r k e n i n g o f the f l u i d , accompanied b y a strong odor
is noted, t h e f l u i d and f i l t e r should be changed a n d
the bands adjusted. A physical change i n t h e f l u i d ,
such as t h i s , m a y be the result of overheating.
To check t h e automatic transmission
fluid
level,
the f o l l o w i n g procedure m u s t be used:
(1) Vehicle m u s t be on level ground.
(2) E n g i n e should be r u n n i n g a t idle speed.
(3) A p p l y p a r k i n g brake.
(4) Place gear selector m o m e n t a r i l y i n each gear
position, ending w i t h t h e lever i n N (neutral).
(5) Remove dipstick, wipe clean a n d determine i f
f l u i d is hot or w a r m . Hot f l u i d is approximately 82°C
(180°F) w h i c h is t h e n o r m a l operating
temperature
after t h e vehicle has been d r i v e n a t least 24 k m (15
miles). T h e f l u i d cannot comfortably be h e l d between
the finger tips. W a r m is w h e n fluid is between 29°-
52°C (85°-125°F).
(6) W i p e dipstick clean, insert u n t i l cap seals. Re-
move t h e dipstick and note t h e reading.
(a) I f the fluid is hot, t h e reading should be i n
the crosshatched area m a r k e d O K .
(b) I f the fluid is w a r m , t h e fluid level should
be between t h e t w o dimples.
(7) I f the fluid level checks low, add sufficient
fluid
to b r i n g t h e level to w i t h i n t h e m a r k s indicated for
the appropriate temperature. I t is i m p o r t a n t proper
l u b r i c a n t i s used i n t h e transmission. M O P A R A T F
P L U S (Automatic
Transmission F l u i d Type 7176)
should be used. Dextron I I automatic transmission
fluid should be used only i f the recommended fluid is
not available.
(8) To prevent d i r t and water f r o m e n t e r i n g t h e

fluid
replacement,
make c e r t a i n t h a t the dipstick cap is seated properly.
CAUTION: Do not overfill the transmission.
