T O R Q U E F L I T E TRANSMISSION
3. TORQUEFLITE OPERATING PRINCIPLES
The transmission, as shown i n F i g u r e 4, combines
a torque converter and an automatic p l a n e t a r y
three speed transmission. The torque converter extends torque m u l t i p l i c a t i o n over a wide range o f
engine speeds. The transmission consists of t w o
m u l t i p l e disc clutches, an o v e r r u n n i n g c l u t c h , t w o
bands, and t w o planetary gear sets to provide t h r e e
f o r w a r d ratios and a reverse r a t i o .
a. Gearshift Control Unit
The transmission is operated by a gearshift c o n t r o l
u n i t consisting of five push buttons, identified b y
R (reverse), N ( n e u t r a l ) , D ( d r i v e ) , 2 (second) and
1 (first).
Mechanical connection between t h e gearshift cont r o l housing and the transmission manual c o n t r o l
valve is obtained t h r o u g h the use of a single pushpull cable, as shown i n F i g u r e 5. One end o f t h e w i r e
cable is secured to the cable actuator i n the g e a r s h i f t
control housing, w h i l e the other end enters t h e t r a n s mission case to engage t h e manual control valve lever
assembly.
Should the R (reverse) b u t t o n be pushed i n , above
a p p r o x i m a t e l y 10 to 12 M P H , i t w i l l move the m a n u a l
control lever t o t h e n e u t r a l position and w h e n t h e
car speed drops below 10 to 12 M P H , i t w i l l again be
necessary to re-engage the R (reverse) push b u t t o n .
A back-up l i g h t s w i t c h (when so equipped) is i n corporated i n t h e gearshift control housing and is
operated b y the R (reverse) push b u t t o n slide.
b. Operating Instructions
Starting the Engine
As a safety precaution, always apply p a r k i n g or foot
brake. The transmission N ( n e u t r a l ) control b u t t o n
m u s t always be pushed i n before the car can be
started. T h i s is necessary since t h e s t a r t e r electrical
c i r c u i t is completed only w h e n the n e u t r a l safety
s w i t c h on the transmission is closed, thus p r e v e n t i n g
the car f r o m being accidentally s t a r t e d while i n gear.
Push Starting
Should the need arise, the engine can be started as
follows by h a v i n g t h e car pushed:
(1)
Push i n the N ( n e u t r a l ) b u t t o n .
(2) T u r n on the i g n i t i o n s w i t c h .
(3) W h e n a speed of a p p r o x i m a t e l y 20 M . P . H . has
been attained, push i n the 1 ( f i r s t ) b u t t o n and t h e
engine should s t a r t .
T o w i n g the car to s t a r t is n o t recommended due t o
the sudden surge of power w h e n the engine starts.

MAINTENANCE, ADJUSTMENTS AND T E S T S
CAUTION
For safety reasons and to prevent possible damage
to the transmission . . . wide open throttle stall test
operations should not be attempted under any circumstances.
Good transmission operation depends d i r e c t l y upon
good engine performance. Therefore, i t is o f u t m o s t
importance t h a t the engine is o p e r a t i n g at f u l l efficiency and at proper idle speed before a t t e m p t i n g
to diagnose or correct any transmission operation.
The engine and t r a n s m i s s i o n should be w a r m e d up
to o p e r a t i n g temperature. A s h o r t drive, a p p r o x i m a t e l y five t o t e n miles, w i t h frequent stops and
s t a r t s w i l l produce n o r m a l o p e r a t i n g temperatures
to the t r a n s m i s s i o n and engine. Check o i l level.
A l l s h i f t s and k i c k d o w n s should occur w i t h i n t h e
speed ranges given i n the S h i f t P a t t e r n S u m m a r y
Chart.
N O T E : A l l shift speeds may vary somewhat due to
production tolerances, type of engine, rear axle ratios
and tire sizes. A l l shifts, however, should be smooth,
responsive and with no noticeable engine runaway.

The f o l l o w i n g precautions should be observed d u r i n g
34 —TORQUEFLITE TRANSMISSION
disassembly of t h e t r a n s m i s s i o n : Cleanliness t h r o u g h
the entire disassembly and assembly cannot be overemphasized. U n i t should be t h o r o u g h l y cleaned
w h e n removed f r o m the vehicle, preferably b y steam.
W h e n disassembling, each p a r t should be placed i n a
suitable solvent, washed, t h e n dried b y compressed
air. Do not wipe parts w i t h shop towels. A l l of the
m a t i n g surfaces i n the transmission are accurately
machined; therefore, careful h a n d l i n g of parts m u s t
be exercised to avoid nicks or b u r r s .
The use o f crocus cloth is permissible where necessary, p r o v i d i n g i t is used carefully. W h e n used on
valves, use extreme care so not to r o u n d off the
sharp edges. T h e sharp edge p o r t i o n is v i t a l l y i m p o r t a n t t o t h i s type valve. Sharp edges prevent d i r t
and foreign m a t t e r f r o m g e t t i n g between t h e valve
and body, thus reducing the possibilities of s t i c k i n g .
W h e n a vehicle has accumulated considerable mileage and i t becomes necessary to r e c o n d i t i o n the

Disassembly, inspection, and assembly procedures
are the same. There is a difference, however, i n line
pressure, governor pressure, planet pinion carrier,
and t h r o t t l e linkage a d j u s t m e n t ; t h e y are as follows:
( 1 ) The line pressure is increased f r o m 90 to 105
psi, (refer to r a m manifold line pressure c h a r t ) . I n
order to achieve t h i s change, a heavier regulator
valve spring is used.
( 2 ) Governor pressure is also changed. (Refer to
r a m m a n i f o l d governor pressure chart.) I n t h i s case,
t h e governor w e i g h t assembly incorporates a heavier
s p r i n g along w i t h a l i g h t e r outer w e i g h t .
( 3 ) Due to the increased torque provided b y r a m

SERVICE PROCEDURES
2. O P E H A I i O N
P o w e r F l i t e combines a h i g h l y efficient torque conv e r t e r and a simple a u t o m a t i c two-speed transmission w h i c h provides exceptionally smooth performance t h r o u g h o u t the e n t i r e speed range. The
transmission is equipped w i t h a n e u t r a l s t a r t i n g safe-
t y s w i t c h w h i c h prevents s t a r t i n g the car i n gear.
A l l normal d r i v i n g can be done i n the d r i v e ( D )

automatically upshifts t h e transmission i n t o direct
d r i v e at the proper t i m e , depending upon the degree
of acceleration desired by the d r i v e r . The s h i f t is
POWERFLITE TRANSMISSION — 79
f u l l y automatic, allowing t h e d r i v e r t o keep constant pressure on the accelerator a t a l l times. I n stantaneous acceleration, w i t h t h e D ( D r i v e ) push
b u t t o n engaged, is accomplished b y pressing the
accelerator pedal t o the floor. T h i s action downshifts
the transmission to low gear.
w i l l move to t h e n e u t r a l position. The d r i v e r is t h e n
required t o again select the proper gear range.
c. Gearshift Control Housing (Refer to Fig. 1)
The L (low) range is provided t o keep the transmission i n low gear regardless of speeds f o r unusual
d r i v i n g conditions such as c l i m b i n g o r descending
mountains or d r i v i n g t h r o u g h sand.
Mechanical connection between the gearshift control
housing and t h e transmission manual control valve
is obtained t h r o u g h the use of a single push-pull
cable. One end o f the w i r e cable is secured to the
cable actuator i n the gearshift housing, while the
other end enters the transmission case t o engage
the manual c o n t r o l valve lever assembly.
" R o c k i n g " the car, when m i r e d i n m u d or snow,
is easily accomplished by a l t e r n a t e l y engaging t h e
R (reverse) and L (low) push buttons.
A back-up l i g h t s w i t c h ( w h e n so equipped) is i n corporated i n the g e a r s h i f t control housing and is
operated by the R (reverse) push b u t t o n slide.
a. Torque Converter
d. Neutral Starting Switch
The torque converter receives i t s o i l supply at a
constant pressure f r o m the f r o n t o i l pump i n t h e
transmission.
The s t a r t i n g m o t o r is w i r e d i n such a w a y t h a t t h e
engine cannot be s t a r t e d unless t h e N ( n e u t r a l ) button is engaged. E n g a g i n g t h e N ( n e u t r a l ) b u t t o n
closes the s t a r t i n g m o t o r c i r c u i t at the n e u t r a l s t a r t i n g switch, located on t h e transmission case ( F i g .
2).
The u n i t is bolted to and supported by the crankshaft flange. I t consists of three basic p a r t s : an
impeller, a t u r b i n e and a stator. The impeller, w h i c h
f o r m s the outer sh^ll of the converter u n i t , is d r i v e n
by the engine. The t u r b i n e is d r i v e n b y the force o f
oil f r o m the impeller vanes. T h e t u r b i n e is splined
to the i n p u t shaft of the transmission. The stator,
located between the impeller and t u r b i n e , serves to
redirect the flow of oil i n t h e u n i t , t h u s m u l t i p l y i n g
engine torque. The stator is m o u n t e d on an overr u n n i n g clutch w h i c h permits i t t o r o t a t e only i n the
direction of impeller and t u r b i n e r o t a t i o n .

h. Road Testing
W h e n f a u l t y operation of the t r a n s m i s s i o n is reported, t r a n s m i s s i o n fluid level and engine idle should
be checked before a n y t h i n g else. Good transmission
operation also depends on good engine operation.
Therefore, before b l a m i n g any r o u g h s h i f t i n g on the
transmission, i t is necessary to make sure t h e engine
is o p e r a t i n g at f u l l efficiency.
If, when tuning the engine, the throttle linkage
between the carburetor and the transmission is disturbed, it will be necessary to readjust the linkage.
Refer to "Throttle Pressure and Throttle Linkage
Adjustment," Paragraph 6.
A f t e r all t h e adjustments and pressure checks are
completed, road test the car under v a r y i n g road conditions. The t r a n s m i s s i o n should respond according
to t h e f o l l o w i n g s h i f t p a t t e r n s :
A l l shift speeds may vary somewhat due to production tolerances, however, the quality of the shifts
should be smooth, responsive, and without noticeable
engine runaway.
Replace the n e u t r a l s t a r t i n g s w i t c h . I n s t a l l the
concave (cupped) s p r i n g washer over t h e threads of
the n e u t r a l s t a r t i n g s w i t c h so t h a t the concave

speeds are increased. M a k e sure ball operates freely
and seals properly. The bronze b u s h i n g used i n t h e
direct clutch piston r e t a i n e r is not replaceable.
N O T E : Particular attention should be paid to the inside diameter of the direct clutch retainer bushing.
Excessive clearance between the direct clutch retainer bushing and the reaction shaft, can permit the
retainer to wobble and reduce the effectiveness of
the reaction shaft seal. Accordingly, if this seal is
ineffective, clutch slippage may result due to loss of
clutch application pressure. Normal direct clutch
bushing inside diameter dimensions (after machining) are 1.8125 inches to 1.8135 inches. Maximum
useable service limit is .004 greater.
Inspect reaction shaft seal r i n g c o n t a c t i n g areas,
