Revision: June 20062007 Versa

Gaskets, seals and O-rings should be replaced any time the A/T is disassembled.

It is very important to perform functional tests whenever they are indicated.

The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.

Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.

Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.

Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.

Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to
Refer to .

After overhaul, refill the A/T with new ATF.

When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque
converter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to AT - 1 7 , "
Changing A/T Fluid" , AT- 1 6 , "Checking A/T Fluid" .
Service Notice or PrecautionsUCS005M4
ATF COOLER SERVICE
If A/T fluid contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T oil cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. Check Service Bulletins for latest A/T oil cooler cleaning pro-
cedure. For radiator replacement, refer to Refer to CO-11, "
RADIATOR" .
TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:

External leaks in the hub weld area.

Converter hub is scored or damaged.

Converter pilot is broken, damaged or fits poorly into crankshaft.

Steel particles are found after flushing the cooler and cooler lines.

Pump is damaged or steel particles are found in the converter.

Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made. (Converter clutch material may be glazed.)

Converter is contaminated with engine coolant containing antifreeze.

Internal malfunction of stator roller clutch.

Heavy clutch debris due to overheating (blue converter).

Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:

The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.

The threads in one or more of the converter bolt holes are damaged.

A/T malfunction did not display evidence of damaged or worn internal parts, steel particles or clutch plate
lining material in unit and inside the fluid filter.

Vehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.

LINE PRESSURE TEST
Line Pressure Test Ports
Location of line pressure test ports are shown in the figure.

Always replace pressure plugs as they are self-sealing
bolts.
Line Pressure Test Procedure
1. Check ATF and engine oil levels. If necessary, add ATF or
engine oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF
reach operating temperature.
3. Install oil pressure gauge to corresponding line pressure test
port.
4. Set parking brake and block wheels.

REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-22, "
Removal and Installation" .
3. Drain the A/T fluid. Refer to AT-16, "
A/T FLUID" .
4. Remove oil pan and oil pan gasket.
5. Check for foreign materials in oil pan to help determine cause of
malfunction. If the ATF is very dark, smell burned or contains for-
eign particles, friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If ATF contains frictional material (clutch, bands, etc.),
replace radiator and flush cooler line using cleaning sol-
vent and compressed air after repair of A/T. Refer to CO-
11, "RADIATOR" .

a. Apply compressed air to the oil hole as shown, and remove
servo release accumulator piston from transaxle case.
CAUTION:
Strong flow of air will push the accumulator piston out
along with a splash of ATF. To avoid this cover the area with
lint-free cloth and blow air little by little.
b. Apply compressed air to the oil hole as shown, and remove N-D
accumulator piston and return spring from transaxle case.
CAUTION:
Strong flow of air will push the accumulator piston out
along with a splash of ATF. To avoid this cover the area with
lint-free cloth and blow air little by little.
c. Remove O-rings (1) from servo release accumulator piston (2)
and N-D accumulator piston (3).
CAUTION:
Wrap the removed servo release accumulator piston (2) and
N-D accumulator piston (3) in a lint-free cloth.
16. Remove lip seals (1) from transaxle case.

Inspection

Inspect the sliding surfaces of each accumulator piston and
transaxle case, and replace if damaged or dented.
(1): Servo release accumulator piston
(2): N-D accumulator piston

Inspect the sliding surfaces of manual valve and valve body, and
replace if damaged or dented.

Inspect each return spring, and replace if damaged, deformed or
worn. Refer to AT-380, "

transaxle case and oil pan.

Do not reuse O-rings, lip seals, oil pan gasket and oil pan bolts.

Apply ATF to manual valve, O-rings, lip seals and sliding surfaces of the transaxle case.
NOTE:

Set manual shaft in “N” position, then align manual plate (1) with
groove in manual valve (2).

After installing control valve assembly to transaxle case, make
sure that selector lever can be moved to all positions.

After completing installation, check for A/T fluid leakage and A/T
fluid level. Refer to AT- 1 6 , "
