B.NormalOperatingTemperature(160°-200°F.)
C.ExtremeOperatingTemperature(260°-300°F.
Figure 2-6 Transmission Oil Level
Thefluidlevelshould be checked at every en-
gine oil change. Add fluid, if necessary,until
properlevel is indicated on dipstick, Fig.2-6.
Properlevel is based on operatingtemperature.
Thefluidlevelshouldalways be checkedafter the
engine has beenrunning to makecertain the fluid
coupling is full. Runthe enginewith the selector
lever in"N" (Neutral) or"P" (Park)position at
800 RPMfor1-1/2 minutes.
Reduce the enginespeed to slowidle,remove
andwipedipstick, and checkfluidlevel.With the
enginestillrunning, add fluidthrough the dipstick
tube to bring the fluid tothe properlevel. At
normaloperatingtemperature,from low mark
(bottomdimple) to"F" requires 1 pint of fluid.
c.ChangingFluid
1. With caron hoist,removecoverplatefrom
bottom of flywheelhousing.
2. Removedrainplugs, Fig.2-7, from,trans-
mission oilpanand fromtoruscover.
NOTE: Itmaybe necessary to rotate fly-
wheel to gainaccess to toruscoverdrainplug.
Figure 2-7 TransmissionDrainPlugs
3. Allow old fluid to draincompletely and then
reinstalldrainplugs.
4. Pour 7 quarts of Hydra-Maticfluidinto the
fillertube.
5. Run engine ata speed of800RPMforap-
proximately 1-1/2 minuteswithselectorlever in
"P" (Park).
6.Reduceenginespeed to slowidle andadd
1-1/2to2 quarts of fluid to bringlevel ondip-
stick to properlevel as indicated by operating
temperature, Fig.2-6.
7. Check for leaks at toruscover and drainplug
andreplacecoverplate on bottom of flywheel
housing and lower carto floor.
8.Turn off ignition and replacedipstick.
NOTE: The capacity ofthe Hydra-Matic
transmission is approximately 9 quarts fora
refill, butthe correctlevel is determined bythe
mark onthe dipstickratherthan bythe amount
added. Itis importantthat the properlevel is
maintained. Donot overfill, as foaming may
occurwhen the fluidheats up.Iftheoil level is
too low,the pressureregulatorwillbecome
noisy,resulting in possiblemalfunction ofthe
transmission.
d. Oil Strainer
The oil intakesystem ofthe1963 Hydra-Matic
transmissionincorporates anoil strainer inthe
transmission oil sump. Itis recommendedthat
thetransmission oil strainer be replacedafter
thefirst30,000milesonly. The procedure for
removing and installing theoil strainer, isdes-
cribed in Section 6, Notes 15cand18f.
8.FrontWheelBearings
Thefrontwheelbearings onall seriescars re-
quirerepacking and adjustingwhen the front
brakes are serviced, butnot before30,000miles.
Whenrepackingthesebearings, usea #2 grade
highmeltingpointwheelbearinggreasefreefrom
anyfillers or abrasives.Refer to Section 4 Note
5, for repackingprocedure.
9. Battery
Thebatteryelectrolytelevelshouldordinarily
bechecked at everyengine oil change. In warm
weather, a checkshould be made at two-week
intervals. Ifthe level is found tobelow,add
colorless,odorlessdrinkingwater in each ofthe
sixcells to bring the level uptothe bottom ofthe
