TRANSAXLE ASSEMBLY
3. Remove the harness from the transaxle.
4. Remove the transaxle to engine and engine to transaxle bolts.
5. Remove the CVT fluid charging pipe.
6. Separate the transaxle from the engine.
7. If necessary, remove the following from the CVT:
• Fluid cooler tube
• Air breather hose
• Brackets
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• When replacing an engine or transaxle you must make sure any dowels are installed correctly during
re-assembly
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.
• Do not reuse O-rings.
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to
.
• After converter is installed to drive plate, rotate crankshaft several turns to check that CVT rotates
freely without binding.
• When installing the CVT to the engine, align the matching mark on the drive plate with the matching
mark on the torque converter.
• When installing CVT assembly to the engine assembly, attach the
bolts in accordance with the following standard.
• When installing the drive plate to torque converter nuts, tighten them temporarily. then tighten the nuts to the
specified torque.
• After completing installation, check for fluid leakage, fluid level, and the positions of CVT. Refer to
TM-253, "Inspection and Adjustment"
• When replacing the CVT assembly, erase EEP ROM in TCM.

Work Flow
INFOID:0000000004201823
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, PNP switch and provides shift control or lock-up
control via CVT solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used with the OBD-related parts of the
CVT system for malfunction-diagnostic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve mal-
function, etc.
It is much more difficult to diagnose an error that occurs intermit-
tently rather than continuously. Most intermittent errors are caused
by poor electric connections or improper wiring. In this case, careful
checking of suspected circuits may help prevent the replacement of
good parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-III (or GST) or a circuit tester connected should be
performed. Follow the “DETAILED FLOW”.
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “Diagnostic Work Sheet” as shown on
the example (Refer to
) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.
DETAILED FLOW
1.
COLLECT THE INFORMATION FROM THE CUSTOMER
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred) using diagnosis worksheet. Refer to
TM-264, "Diagnostic Work Sheet"
>> GO TO 2.
2.
CHECK SYMPTOM 1
Check the following items based on the information obtained from the customer.
• Fail-safe. Refer to
.
• CVT fluid inspection. Refer to
.
• Line pressure test. Refer to
TM-423, "Inspection and Judgment"
.
