PRECAUTIONS
Revision: 2006 November2007 350Z
PRECAUTIONSPFP:00001
Precautions for Battery ServiceNCS0000N
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Service Notice or PrecautionsNCS0000O

If transmission assembly is removed from the vehicle, always replace CSC (Concentric Slave Cylinder)
body and CSC tube . Return CSC body insert to original position to remove transmission assembly. Dust
on clutch disc sliding parts may damage seal of CSC body and may cause clutch fluid leakage.

Do not reuse transmission oil, once it has been drained.

Check oil level or replace oil with vehicle on level ground.

During removal or installation, keep inside of transmission clear of dust or dirt.

Check for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts they are applied to.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.

Be careful not to damage sliding surfaces and mating surfaces.

Do not hold control lever housing to prevent bushing of control lever housing from deformation when mov-
ing transmission assembly.

Changing M/T OilNCS0000T
DRAINING
1. Start the engine and warm up the transmission unit sufficiently.
2. After stopping engine, remove filler plug and drain plug to drain oil.
3. Replace gasket on drain plug with new one. Screw drain plug into transmission case, and tighten to the
specified torque. Refer to MT-22, "
Case Components" .
CAUTION:
Do not reuse gasket.
FILLING
1. Fill new oil into the transmission to the level of the filler plug mounting hole.
2. Replace gasket on filler plug with new one. Screw filler plug into transmission case, and tighten to the
specified torque. Refer to MT-22, "
Case Components" .
CAUTION:
Do not reuse gasket.
Checking M/T OilNCS0000U
OIL LEAKAGE AND OIL LEVEL

Check if oil is leaking from transmission or around it.

Check oil level from filler plug mounting hole as shown in the fig-
ure.
CAUTION:
Never start engine while checking oil level.

When screwing in filler plug with a new gasket, first screw into
the transmission by hand, then tighten to the specified torque.
Refer to MT-22, "
Case Components" .
CAUTION:
Do not reuse gasket.Oil grade and viscosity : Refer to MA-11, "
Fluids and Lubricants" .
Oil capacity
: Approx. 2.93 (6-1/4 US pt, 5-1/8 lmp pt)

CAUTION:
If transmission assembly is removed from the Vehicle, always replace CSC (Concentric Slave Cylin-
der) body and CSC tube. Return CSC body insert to original position to remove transmission assem-
bly. Dust on clutch disc sliding parts may damage seal of CSC body and may cause clutch fluid
leakage.
