< REMOVAL AND INSTALLATION >

[CVT: RE0F09B]

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 

EM-52, "Removal and Installa-

tion"

.

• 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-240,

"Inspection"

 and 

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 

TM-264

) 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 

TM-397, "Fail-safe"

.

• CVT fluid inspection. Refer to 

TM-416, "Inspection"

.

• Line pressure test. Refer to 

TM-423, "Inspection and Judgment"
