12) Disconnect couplers from solenoid valves, and transmission
temperature sensor.
Remove transmission temperature sensor.
13) Remove valve body assembly (1).
14) Remove solenoid harness assembly.
15) Remove accumulator pistons and springs.
To remove C0 (1), C2 (2) and B1 (3) accumulator pistons
and springs, position a rag on pistons to catch each piston.
To remove pistons, force low-pressure compressed air (1 kg/
cm
2, 15 psi, 100 kPa, max) into hole (4) as shown in figure,
and pop each piston into the rag.
To remove B0 and C1 accumulator pistons and springs,
remove each snap ring and accumulator spacer, then
remove spring and piston.
16) Remove torque converter housing (1).
a) Remove housing bolts.
b) Remove housing while tapping around it lightly with a plas-
tic hammer. CAUTION:
Be careful not to let manual valve fall off when removing
valve body assembly.
NOTE:
There are three kinds of bolts (bolts A, B and C) fixing
valve body assembly.
2. Bolt A
3. Bolt B
4. Bolt C
NOTE:
Do not push accumulator pistons with fingers or any-
thing before removing them. Pushing them may cause
compressed fluid in accumulator to spew out of hole and
get to your face and clothes.
NOTE:
Never reuse bolts A shown in figure.

DISASSEMBLY/ASSEMBLY OF SUBASSEMBLY
OIL PUMP
CAUTION:
 Keep component parts in group for each subassembly and avoid mixing them up.
 Clean all parts with cleaning solvent thoroughly and air dry them.
 Use kerosene or automatic transmission fluid as cleaning solvent.
 Do not use wiping cloths or rags to clean or dry parts.
 All oil passages should be blown out and checked to make sure that they are not obstructed.
 Keep face and eyes away from solvent spray while air blowing parts.
 Check mating surface for irregularities and remove them, if any, and clean it again.
 Soak new clutch discs and brake discs in transmission fluid for at least 2 hours before assembly.
 Replace all gaskets and O-rings with new ones.
 Apply automatic transmission fluid to all O-rings.
 When installing seal ring, be careful so that it is not expanded excessively, extruded or caught.
 Replace oil seals that are removed and apply grease to their lips.
 Before installing, be sure to apply automatic transmission fluid to sliding, rolling and thrusting sur-
face of all component part. Also after installation, make sure to check each part for proper opera-
tion.
 Always use torque wrench when tightening bolts.

UNIT ASSEMBLY
CAUTION:
 Automatic transmission consists of highly precise parts. As even a flaw in a small part may cause
oil leakage or decrease in function, check each part carefully before installation.
 Clean all parts with compressed air. Never use wiping cloths or rags.
 Before assembling new clutch discs and brake band, soak them in automatic transmission fluid for
at least 2 hours.
 Be sure to use new gaskets and O-rings.
 Lubricate O-rings with automatic transmission fluid.
 Apply automatic transmission fluid on sliding or rotating surfaces of the parts before assembly.
 Use yellow petrolatum grease or Suzuki Super Grease C to retain parts in place.
 Be sure to install thrust bearings and races in correct direction and position.
 Make sure that snap ring ends are not aligned with one of cutouts and are installed in groove cor-
rectly.
 Do not use adhesive cements on gaskets and similar parts.
 Be sure to torque each bolt and nut to specification.
