NOTICE:

• If the following parts ha ve been replaced, initialize the TCM and perform a road test to allow the TCM to learn (See page AX-25). – Valve body assembly – Shift solenoid SL3 – Shift solenoid SL4

• If the following parts have been replaced, perform a road test to allow the TCM to learn (See page AX-25). – Shift solenoid SL1 – Shift solenoid SL2

• If the TCM or transaxle has been replaced, register the transmission compensation code in the TCM (See page AX-19).

• Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assembly, engine assembly or ECM (See page AX-25).

1. The automatic transaxle is composed of highly precision-finished part s which need careful inspection before reassembly. Even a small nick could cause fluid leakage or affect transmission performance. The instructions here are organized so that you work on only one component group at a time. This will help avoid confusion caused by similar-looking parts of different sub-assemblies being on your workbench at the same time. The component groups are inspected and repaired from the converter housing side. Complete as much as possible of the inspection, repair and reassembly before proceeding to the next component group. If a defect is found in a certain component group during reassembly, inspect and repair this group immediately. If a component group cannot be assembled because some parts are being ordered, be sure to keep all parts of the group in a separate container while proceeding with disassembly, inspection, repair and reassembly of other component groups. Recommended: ATF WS

2. All disassembled parts should be washed clean and any fluid passages and holes should be blown through with compressed air.

3. Dry all parts with compressed air. Never use a shop rag or a piece of cloth to dry them.

4. When using compressed air, always aim away from yourself to prevent accidentally spraying ATF or kerosene in your face.

5. Only recommended automatic transmission fluid or kerosene should be used for cleaning.

AX–2

U660E AUTOMATIC TRANSAXLE – AUTOMATIC TRANSAXLE SYSTEM

6. After cleaning, the parts should be arranged in the correct order for efficient inspection, repair, and reassembly.

7. When disassembling a valve body, be sure to match each valve together with its corresponding spring.

8. New discs for the brakes and clutches must be soaked in ATF for at least 15 minutes before reassembly.

9. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with ATF prior to reassembly.

10.All gaskets, seals, and rubber O-rings should be replaced with new ones.

11.Do not apply adhesive cement s to g asket s and si milar parts.

12.Make sure that the ends of a snap ring are not aligned with one of the cutouts and that the snap ring is installed in the groove correctly.

13.When replacing a worn bushing, the sub-assembly containing the bushing must also be replaced.

14.Check thrust bearings and races for wear or damage. If they are damaged, replace them.

15.When working with FIPG material, you must observe the following: – Using a razor blade and a gasket scraper, remove

all the old packing (FIPG) material from the gasket surface.

– Thoroughly clean all components to remove any

loose material.

– Clean both sealing surfaces with a non-residue

solvent.

– Parts must be reassembled within 10 minutes of

application. Otherwise, the packing (FIPG) material must be removed and reapplied.

DEFINITION OF TERMS

Term Definition

Monitor description Description of what the TCM monitors and how it detects malfunctions (monitoring purpose and its details). Related DTCs Diagnostic code

Preconditions that allow the TCM to detect malfunctions.

Typical enabling condition

Sequence of operation

Required sensor/components The sensors and components that are used by the TCM to detect malfunctions.

Frequency of operation

Duration Malfunction thresholds Beyond this value, the TCM will conclude that there is a malfunction and set a DTC.

MIL operation

Component operating range

With all preconditions satisfied, the TCM sets the DTC when the monitored value(s) exceeds the malfunction threshold(s).

The priority order that is applied to monitoring, if multiple sensors and components are used to detect the malfunction. While another sensor is being monitored, the next sensor or component will not be monitored until the previous monitoring has concluded.

The number of times that the TCM checks for malfunctions per driving cycle. "Once per driving cycle" means that the TCM detects malfunction only one time during a single driving cycle. "Continuous" means that the TCM detects malfunction every time when the enabling conditions are met.

The minimum time that the TCM must sense a continuous deviation in the monitored value(s) before setting a DTC. This timing begins after the "typical enabling conditions" are met.

MIL illumination timing after a defect is detected. "Immediately" means that the TCM illuminates MIL the instant the TCM determines that there is a malfunction. "2 driving cycle" means that the TCM illuminates MIL if the same malfunction is detected again in the 2nd driving cycle.

Normal operation range of sensors and solenoids under normal driving conditions. Use these ranges as a reference. They cannot be used to judge if a sensor or solenoid is defective.

U660E AUTOMATIC TRANSAXLE – AUTOMATIC TRANSAXLE SYSTEM

SYSTEM DESCRIPTION

1. SYSTEM DESCRIPTION

(a) The ECT (Electronic controlled automatic transaxle)

is an automatic transaxle that has its shift timing electronically controlled by the Transmission Control Module (TCM). The TCM detects electrical signals that indicate engine and driving conditions, and controls the shift point, based on driver's habits and road conditions. As a result, fuel efficiency and transaxle performance are improved. Shift shock has been reduced by controlling the engine and transaxle simultaneously. In addition, the ECT has features such as:

• Diagnostic function.

• Fail-safe function for use when a malfunction occurs.
