AUTOMATIC TRANSMISSION SYSTEM
PRECAUTIONS
CAUTION:
Execute reset memory operation (AT initialization) when replacing the automatic transmission ASSY, engine ASSY, valve body ASSY, transmission wire, or TCM. (Refer to )
NOTE:
Reset memory operation is not completed just by disconnecting the battery cable.
1. Precautions for removal and installation procedures
(1) Since the automatic transmission consists of parts with a very precise finish, careful inspection is required before assembling these parts. Even a small scratch may cause liquid leakage or affect the performance. Instructions in this chapter are organized so that the work for only 1 component group is performed at a time. This is to avoid confusion which can occur when parts having similar appearance but for different SUB-ASSY exist in the same workbench at the same time. Inspect and repair the component group from the converter housing side. Try to complete the inspection, repair, or assembly work before proceeding to the next component group. If any defect is found in a specific component group during assembly, immediately check and repair the group. When a component group cannot be assembled due to the parts order, be sure to store all parts of the group in another container while another component group is being disassembled, checked, and assembled. The auto fluid (ATF) WS is recommended.
(2) Wash all of the removed parts and blow through all of the liquid passages and holes with compressed air.
(3) Dry all parts with compressed air. Never dry the parts using rugs and cloths in the work area.
(4) When using compressed air, do not point the air outlet toward you to prevent auto fluid and detergent from being blown to your face by mistake.
(5) Use only the recommended automatic transmission fluid or appropriate detergent for cleaning.
(6) After washing, arrange the parts in the correct order for efficient inspection, repair, and assembly.
(7) When removing the valve body, be sure to keep each valve with the corresponding spring.
(8) Soak new discs (for replacement) of the brake and clutch in ATF for at least 15 minutes before the assembly.
(9) Before the assembly, apply ATF to all of the oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces.
(10) Replace all gaskets and rubber O-rings with new parts.
(11) Do not apply adhesive cement to gaskets and similar parts.
(12) Check that the both ends of the snap ring do not overlap the notch and the snap ring is installed in the groove correctly.
(13) When replacing a worn bushing, be sure to replace the SUB-ASSY including the bushing.
(14) Check for wear and damage of the thrust bearing and race. Replace them as required.
(15) Observe the following precautions when handling FIPG material.
·Completely remove the old sealant (FIPG) material from the gasket surface using a razor or gasket scraper.
·Carefully clean all the components and remove materials that are coming off.
·Clean the both surfaces of the seal with appropriate detergent.
·The parts must be assembled within 10 minutes after sealant (FIPG) is applied. If it is impossible, remove the sealant (FIPG) material and apply it again.
DEFINITIONS OF TERMS
Term
 Definition
Monitor description
 Description of what TCM monitor is and the failure detection method (purpose and detail of observation)
Applicable diagnostic codes
 Diagnostic codes
Standard enabling condition
 Conditions required so that TCM can detect failures.
When all of the required conditions are satisfied, TCM sets diagnostic codes if the observation value exceeds the failure threshold.
Operation order
 Priority order applied to observation when multiple sensors and components are used for failure detection.
When a sensor is observed, the next sensor or component is not observed until the observation is completed.
Requirement sensor/component
 The sensor and component used by TCM for failure detection
Operation frequency
 The number of times that TCM checks failure per driving cycle
“Once per driving cycle” means that TCM detects failure only 1 time during a single driving cycle.
“Consecutive” means that TCM detects failure each time the enabling condition is satisfied.
Period
 The minimum time period in which consecutive deviation of the observation value must be detected before TCM sets diagnostic codes. The time measurement starts after “standard enabling condition” is satisfied.
Failure threshold
 If the value is exceeded, TCM concludes that a failure is found and sets diagnostic codes.
MIL operation
 The timing of MIL illumination after a defect is detected.
“Immediate” means that MIL illuminates at the moment when TCM judges that a failure is found.
“2nd driving cycle” means that MIL illuminates when TCM detects the same failure in the 2nd driving cycle.
Component operation range
 Normal operation range of the sensor and solenoid under the normal driving condition
Use these ranges as reference.
Do not use them to judge whether the sensor or solenoid has a defect or not.
FUNCTION INSPECTION
1. Check of shift lock operation
(1) Shift the select lever to the P position.
(2) Check that the select lever cannot be shifted to ranges other than P position when it is operated.
(3) Check that the select lever can be shifted to ranges other than P position with IG ON and the brake pedal depressed.
2. Check of shift lock release button operation
(1) Check that the select lever can be shifted to ranges other than P position when it is operated with the shift lock release button pressed.
3. Time lag check
CAUTION:
·Always perform the inspection after the engine check and adjustment.
·Perform the inspection at an oil temperature (60 to 90°C {140 to 194°F}) in normal driving temperature.
·Perform the inspection with the A/C OFF.
(1) Apply the parking brake and set the wheel stoppers.
(2) Start the engine.
(3) Shift from N position to D or R position with idling while depressing the brake pedal, and measure the time until a small shock is felt.
Standard value :  N→D position 1.2 seconds or less :  N→R position 1.5 seconds or less
CAUTION:
·Make measurements 3 times and take the average value.
·Allow 1 minute interval when performing consecutive measurements.
5. Line pressure check
CAUTION:
·Wash the equipment and hoses with appropriate detergent before and after measurement.
·Always perform the inspection after the engine check and adjustment.
·Perform the inspection at an oil temperature (60 to 90°C {140 to 194°F}) in normal driving temperature.
·Perform the inspection with the A/C OFF.
·Do not perform the inspection continuously for 5 seconds or more at stall. (Working time for the sequence from the accelerator full close, full open, stall speed reading, to the accelerator full close) Ignoring this instruction causes engine oil and ATF deterioration which has adverse effect on the clutch and brake.
·After performing the stall test, be sure to cool down the engine for at least 1 minute with the select lever set in P or N position, and at an idle speed of 1200 r/min or less.
·If the stall speed is higher than the specified range, finish the stall test in as short a time as possible, in order to prevent the automatic transmission from being damaged.
·Perform the stall test in normal mode.
(1) Remove the under cover front AL.
(2) Remove the under cover COMPL T/M.
(3) Remove the exhaust pipe ASSY FR.
(4) Attach the SST on the transmission.
SST     18681AA040  498897700  498575400
CAUTION:
·Use 18681AA040 with genuine O-ring (17006AA000) attached.
·Route the hose so that it does not contact the exhaust pipe.

DESCRIPTION OF FUNCTIONS
1. Diagnosis function
(1) The check engine warning light illuminates when a malfunction occurs in the AT system.
CAUTION:
The light goes off if the malfunction item returns to the normal state. However, diagnostic codes are recorded.
(2) Diagnostic results of malfunction occurrence are recorded in the transmission control computer.
CAUTION:
Do not disconnect the MAIN fuse, AT+B fuse, and battery terminal until the check finishes.
2. Failsafe function
(1) When there is an open or short circuit in any solenoid valve system, only the mechanical hydraulic circuit operates and the manual shift control is initiated. (When open and short circuits occur, the transmission control computer stops continuity of all solenoid valves.)

Monitor description
These diagnostic codes indicate problems of the wiring harness in the neutral start switch ASSY and neutral start switch ASSY circuit.
The neutral start switch ASSY detects the select lever position and sends signals to TCM.
For safety, the neutral start switch ASSY detects the select lever position. It is to allow the engine to start only when the select lever is in P or N position.
The neutral start switch ASSY sends signals corresponding to shift positions (P, R, N, D, or M) to TCM. When receiving 2 or more position signals at one time, TCM determines that the switch or related parts have a problem. TCM turns on MIL and records the diagnostic codes.
If open or short circuit is detected, all contacts of shift positions are turned to OFF.

Monitor description
This diagnostic code indicates that the automatic transmission fluid (ATF) temperature sensor output is abnormal and the sensor itself is defective. The ATF temperature sensor converts ATF temperature into electric resistance. TCM specifies ATF temperature based on the resistance and detects open or short circuit in the ATF temperature circuit or defects of the ATF temperature sensor.
If the vehicle drives for a certain period of time, the ATF temperature should rise. If the ATF temperature is less than 20°C and the input voltage fluctuation is 0.05 V or less after the vehicle drives for a certain period of time, TCM recognizes the defect and turns on MIL.

Monitor description
This diagnostic code indicates “stuck OFF” of the transmission 3 way solenoid ASSY (S4), “stuck ON” of the clutch control solenoid No.1 (SL2), or a defect of the brake control valve. TCM switches ON/OFF of the shift solenoid valve to command shifting. If the gear position commanded by TCM is different from the actual gear position, TCM turns on MIL and records the diagnostic code.

DTCP0979 Shift Solenoid “C” Control Circuit Low
DTCP0980 Shift Solenoid “C” Control Circuit High
Circuit description
Signals from the transmission control computer ASSY change the vehicle speed from 1st to 6th gear according to the combination of the transmission 3 way solenoid ASSY (S1, S2, S3, S4, SR) and the clutch control solenoid No.1 (SL1, SL2). When there is an open or short circuit in the solenoid valve system, the transmission control computer ASSY stops continuity to all solenoids as the fail safe function. As a result, only the mechanical hydraulic circuit is available and the manual shift control is initiated.

Monitor description
The torque converter lock-up is controlled by TCM based on the transmission revolution sensor (NT, SP2), engine r/min, engine load, engine temperature, vehicle speed, transmission temperature, and selected gear. TCM compares engine r/min (NE) with input turbine r/min (NT) to determine the lock-up status of the torque converter. TCM compares input turbine r/min (NT) and output shaft r/min (SP2) to calculate the actual transmission gear. If the condition is appropriate, TCM applies control voltage to the lock-up control solenoid (SLU) and requires “lock up”. When the lock-up control solenoid (SLU) turns to ON, it applies pressure to the lock up relay valve to lock the torque converter clutch.
If TCM does not detect lock up after the lock up is requested or detects lock up even though it is not requested, TCM recognizes it as a malfunction of the lock-up control solenoid (SLU) or lock up system performance. TCM turns on MIL and records the diagnostic codes.
