PRECAUTION

PRECAUTIONS

Service Notice or Precautions for Manual Transmission

INFOID:0000000001732863

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.

• Never 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.

• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to out-

side. If tightening sequence is specified, observe it.

• Never damage sliding surfaces and mating surfaces.
• Never hold control lever housing to prevent bushing of control lever housing from deformation when

moving transmission assembly.
