1. Torque transmission to engine block mounting bolt
to 35 lb. ft.
2. Install propeller shaft in original position.
3. Connect converter and flywheel in original position
and torque bolts to 30 lb. ft.
4. Lower car and, if transmission was disassembled, add
6 pints of transmission fluid (10 pints if converter was
replaced) through the filler tube.
5. With the manual control lever in park position, start
engine, DO NOT RACE ENGINE, apply emergency brake
and move selector lever through each range.
6. With selector lever in park, engine running, check
fluid level.
7. Add additional fluid to bring level between the two
small dimples located below the add mark on the dipstick.
This is the correct reading at room temperature,
approximately 65" to 85°F. (18" to 29°C.).
PRELIMINARY INSTRUCTIONS
1. Before starting disassembly of the transmission, it
should be thoroughly cleaned externally to avoid getting dirt
inside.

Converter Holding Tool
2. Place transmission on a CLEAN work bench and use
CLEAN tools during disassembly. Provide clean storage
space for parts and units removed from transmission.
3. The transmission contains parts which are ground and
highly polished, therefore, parts should be kept separated to
avoid nicking and burring surfaces.
4. When disassembling transmission, carefully inspect all
gaskets at times of removal. The imprint of parts on both sides
of an oil gasket will show whether a good seal was obtained.
A poor imprint indicates a possible source of oil leakage due
to gasket condition, looseness of bolts or uneven surfaces of
parts.
5. None of the parts require forcing when disassembling
or assembling transmission. Use a rawhide or plastic mallet
to separate tight fitting cases
-
do not use a hard hammer.
