MANUAL TRANSMISSION
The repair groups found within the 4 TRANSMISSION section contain manual and automatic transmission service and
repair information. Some of the information contained in these
repair groups is intended to be used as a guide for the professional or experienced automotive technician. In addition,
some of the operations require special equipment. Transmission and final drive rebuilding are specialized repairs requiring
many special Saab tools. Therefore, these operations are not
within the scope of this manual and have not been included.
~~~:::~-:~~~~:ir:~E~:~~i;~:~~~i~n::~i~::~~::;;~~~
Procedures for changing the manual transmission lubricant,
automatic transmission fluid, or final drive fluid (automatics
only) are covered in 1 LUBRICATION AND MAINTENANCE.
Removal of the transmission is covered in 2 ENGINE.
Transmission Assembly
The Saab transmission is a unique design in that it is bolted
directly to the bottom of the engine. The top section of the
transmission housing serves as the engine oil sump and the
engine oil is completely sealed off from the manual transmission lubricant.
drive housing containing the differential, and the ring and pinion gears. The transmission and final drive housing has one
common bath of lubricating oil.
The clutch, pressure plate, and release bearing can all be
serviced without removing the engine or transmission. In addition, the clutch slave cylinder and engine flywheel can be
serviced in the car as well. See 2 ENGINE for information on
removing the flywheel.
WARNING
The clutch disc contains asbestos fibers. Asbestos materials
can cause asbestosis. Always wear an OSHA approved respirator and protective clothing when handling components containing asbestos. Do not use compressed air. Do not grind,
heat, weld, or sand on or near any asbestos materials. Only approved cleaning equipment should be used to service the clutch
disc or areas containing asbestcs dust or asbestos fibers.
Power is transferred from the engine down to the transmission via a chain at the front of the engine/transmission assembly. Power then 'flows through the gearset to the 'final drive and
out to the drive axles to drive the front wheels.

Manual transmission with integral final drive.
Fig. 2. shows the internal components of the transmission.
A description of several of the main components is given. Remember that power flows from the engine to the transmission
via the clutch and primary chain. From the chain, power flows
down into the gearbox, and to the final drive where the drive
axles attach.
Clutch, Pressure Plate, Release Bearing
The clutch disc, pressure plate, and release bearing are located at the front of the car behind a plastic cover. They are
removed and installed together. The clutch disc transmits
power to the primary chain via a splined input shaft. See 411
Clutch.
Clutch Master and Slave Cylinders
The clutch is hydraulically actuated. The master cylinder
supplies pressure to the slave cylinder. The brake fluid reser-
AUTOMATIC TRANSMISSION
voir supplies the clutch master cylinder with hydraulic fluid.
The slave cylinder moves the release bearing, which presses
on the fingers of the pressure plate allowing the clutch disc to
rotate independent of engine speed. See Fig. 3. See 412
Clutch Control.
AUTOMATIC TRANSMISSION
The automatic transmission is shown in Fig. 4. At one end of
the transmission is the integral final drive housing. Inside the final drive housing are the differential and the ring and pinion
gears. The final drive housing, containing oil for lubricating the
final drive gears, is completely sealed off from the transmission
case. The transmission case contains automatic transmission
fluid (ATF) for the ATF pump, the hydraulic controls, and the
planetary gear system. See Fig. 5. ATF does not circulate unless the engine is running, so the transmission parts are only
partially lUbricated when the engine is turned off.

CAUTION
• The following rules must be observed if a car with automatic
transmission has to be towed:
• The selector lever must be in position N.
• The ATF level must be topped up an additional 2.0 I (2.1 qt.).
After towing, drain the fluid so the transmission has the correct
level.
ATF Pump
The automatic transmission fluid (ATF) circulates through
the transmission under pressure. The ATF pump that creates
this pressure is located at the top front of the transmission.
The splined pump driveshaft is connected directly to the
torque converter housing, so ATF circulates whenever the engine is running. ATF is drawn from the ATF sump through a
strainer into the pump.
• The car must not be towed a distance greater than 40 to 50
km. (25 to 30 miles).
Planetary Gear System
• The towing speed must not exceed 25 mph (40 km/h)
Torque Converter
The torque converter is a doughnut-shaped assembly located between the engine and the transmission. The torque
converter is a fluid coupling. The torque converter transmits
engine output to the transmission, and also multiplies engine
torque at low vehicle speeds. The engine and transmission
must be removed and separated to service the torque converter and drive plate.
AUTOMATIC TRANSMISSION
A torque converter alone cannot supply the torque multiplication needed for all driving conditions. The torque converter
therefore drives through a planetary gear system which can
operate at different drive ratios. The planetary gear system
consists of two sun gears, two sets of pinions, a pinion carrier
and a ring gear.
The two hydraulically-operated multiple-disc clutches control the routing of power to the planetary gearsets. The front
clutch connects the converter to the forward sun gear. In reverse, the rear clutch connects the converter to the reverse
sun gear.
