+When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.
MEF040DA
+Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions prop-
erly or not. (See page AT-116.)
SAT964I
+After performing each TROUBLE DIAGNOSIS, perform
ªDTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DUREº.
The DTC should not be displayed in the ªDTC CONFIRMA-
TION PROCEDUREº if the repair is completed.
+Before proceeding with disassembly, thoroughly clean the out-
side of the transaxle. It is important to prevent the internal parts
from becoming contaminated by dirt or other foreign matter.
+Disassembly should be done in a clean work area.
+Use lint-free cloth or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the opera-
tion of the transaxle.
+Place disassembled parts in order for easier and proper
assembly.
+All parts should be carefully cleaned with a general purpose,
non-flammable solvent before inspection or reassembly.
+Gaskets, seals and O-rings should be replaced any time the
transaxle 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 disas-
sembled 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
