It is not necessary to use the "Reverse'' switch to
shift out of reverse gear to neutral or a forward gear.
Back-up lights are automatically illuminated when
the shift to reverse is made.
Information concerning the reverse solenoid will
be found in Section 7 (Electrical) of this manual.

MAINTENANCE
At intervals indicated in Section 10 (Lubrication)
of this manual, the transmission should be drained,
flushed and refilled with a good grade of the correct
lubricant.
To insure maximum life of the transmission and
prevent premature failure, the original "factory fill"
lubricant should be drained before putting vehicle
into regular service or after 1,000 miles and not over
4,000
miles.

as a lapping compound which accelerates wear of all
parts. Draining the factory lubricant prior to 4,000
miles also prevents lubricant contamination caused
by differences in the "factory fill" and the lubricant
used by the operator when topping.
When the transmission lubricant is changed, metal
particles adhering to the magnetic plug should be
removed. If excessive metal particles are found, a
careful check should be made of the transmission to
determine if unusual wear is taking place. A check
should be made periodically for leakage, unusual
noise or other indications of faulty operation.
For highway service it is recommended that the
transmission oil filter element be changed every
15,000 miles.
Lubricant may be added to transmission through
the dipstick tube. Appropriate marks on dipstick in-
dicate the correct level.
REMOVAL AND REPLACEMENT
Support the transmission case securely. Remove
cap screws which attach the transmission to the
engine flywheel housing. Carefully slide transmission
housing away from the engine until drive gear shaft is
free of clutch plates.
CAUTION:
The transmission case must be moved
straight away from the engine. Otherwise damage to
the pilot shaft may result.
In re-installation, care should be taken to ensure
that the pilot shaft is aligned with splines of clutch
driven discs. Do not use excessive force to bring the
engine and transmission case together. Refer to Sec-
tion 5 (Clutch) for information regarding alignment
pf clutch driven discs in reassembly.
AUTOMATIC TRANSMISSION TO
COACH ENGINE INSTALLATION
Care should be taken for proper installation of the
automatic transmission to the coach engine after servicing.
Troubles may occur as the result of the transmission
converter pilot not being properly indexed with the engine
crankshaft adaptor.
To avoid this problem, the following procedure is
recommended and will apply generally for all installation.
Match-up should occur easily and force is not necessary
if proper index and alignment exists.
(A) Line up transmission with engine, making sure the
nose of the converter pilots in the crankshaft hub adapter.
NOTE: Engine flywheel housing face and converter
housing face must be flush with each other or proper
converter nose pilot has not been obtained.
(B) Rotate engine one revolution.
(C) Install four or more flywheel housing capscrews·
equally spaced. NOTE: These screws must not be used to
pull transmission converter housing face flush with
engine flywheel housing face.
(D) Install one flex plate capscrew. Rotate engine 180°
and install second capscrew.
