TRANSMISSION
The transmission, Fig. 37, is of the Synchronized Silent Mesh design, incorporating the
"blocker type" synchronizing unit which assures an absence of gear clashing when shifting.
It provides for three speeds forward and one reverse. All gears are of helical cut tooth
design, assuring quiet operation in all speeds.
Gear shifting is accomplished by a steering gear column control known as HANDY
SHIFT. The four speeds are in the conventional "H" plate order.
When in neutral the shift lever is in a horizontal position in the second and high rail, see
Fig. 7. To shift into reverse gear the lever must be raised and moved forward. Movement
to low gear is by pulling the lever backward in the same rail. The shift into second gear
is forward to neutral position, then press lever down and move forward. Moving the lever
backward gives high gear position.
LUBRICATION—STANDARD TRANSMISSION—The transmission is fit-
ted with one drain plug located at the bottom of the case and one filler plug on the right
side.
Remove the filler plug every 1,000 miles and check fluid level. As agitation causes
all gear oils to foam, the car should be permitted to stand idle a few minutes
before checking the level. This will allow the foam to subside and assure a
check of the actual oil level.
At intervals of 5,000 miles the oil should be drained and the transmission refilled with
new lubricant. In summer use 2 pounds of S.A.E. 90 E.P. gear oil and in winter use an
S.A.E. 80 E.P. grade.
If the unit is flushed out, it should be refilled with 2
1
/
4
pounds of the proper lubricant.
Should hard shifting be encountered in extremely cold weather, drain out 2 ounces of
transmission oil, add 2 ounces of kerosene and refill to proper level with oil.
LUBRICATION—TRANSMISSION WITH OVERDRIVE—As the same
grades of gear oil recommended for the transmission are used in the Overdrive, communicating
passages are provided between the two units. Separate drain and filler plugs are also provided
in the Overdrive housing. The drain plug is located on the bottom and the filler plug is on
the right side of the housing.
To check fluid level, first remove Overdrive filler plug and determine level, which
should be even with lower edge of hole. If level is low, refill to correct level. Then
check oil level in transmission and refill as required.
To drain and refill, first be sure lubricant is warm as it will flow more freely. Remove
both drain plugs and drain all old lubricant. Replace plugs. Refill Overdrive first,
permitting level to come up to bottom of filler plug hole. Next refill transmission to
bottom of level of the filler plug hole. Replace both plugs.
Should it be necessary to thin the lubricant to facilitate shifting in extremely cold
weather, drain out 2
1
/2 ounces of lubricant, add 2
1
/2 ounces of kerosene and then refill
to proper level with oil.
