Automatic Transmission - U151E: Other Toyota RAV4 III

PRECAUTION

Note. Perform the RESET MEMORY procedures (A/T initialization) when replacing the automatic transaxle assembly, engine assembly or ECM (see INITIALIZATION ). Perform the REGISTRATION (VIN registration) when replacing the ECM (see BASIC INSPECTION ).

HINT

RESET MEMORY cannot be completed by only reconnecting the cable to the negative (-) battery terminal.

Note. The automatic transaxle is composed of precision-made parts, necessitating careful inspection before reassembly because even a small nick could cause fluid leakage or affect performance. The procedures are organized so that you work on only one component group at a time. This will help avoid confusion with 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. Whenever possible, complete 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 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. Use of Toyota Genuine ATF WS is recommended. All disassembled parts should be washed clean, and compressed air should be blown through any fluid passages and holes. Dry all parts with compressed air. Never use cloth. The recommended ATF or kerosene should be used for cleaning. After cleaning, the parts should be arranged in the order they were removed for efficient inspection, repairs, and reassembly. When disassembling a valve body, be sure to match each valve with its corresponding spring. New discs for the brakes and clutches that will be used for replacement must be soaked in ATF for at least 15 minutes before reassembly. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with ATF prior to reassembly. All old gaskets and rubber O-rings must be replaced. Do not apply adhesive cement to gaskets and similar parts. Make sure that the ends of the snap rings are not aligned with any cutouts. Also make sure that snap rings are correctly installed into the grooves. If a worn bushing is to be replaced, the sub-assembly containing the bushing must also be replaced. Check the thrust bearings and races for wear or damage. Replace them if necessary. Use petroleum jelly to keep parts in place. When working with FIPG material, perform the following: Using a razor blade and gasket scraper, remove all old FIPG material from the gasket surface. Clean all components thoroughly to remove all foreign matter. Clean both sealing surfaces with a non-residue solvent. Apply FIPG material in a continuous line approximately 1 mm (0.04 in.) in diameter on the sealing surface. Reassemble parts within 10 minutes of applying FIPG material. Failing to do so will require the FIPG material to be removed and reapplied.

MECHANICAL SYSTEM TESTS

1. STALL SPEED TEST HINT: This test is to check the overall performance of the engine and transaxle. NOTE: Do not perform the stall speed test longer than 10 seconds. To ensure safety, perform this test in an open and level area that provides good traction. The stall speed test should always be performed with at least 2 people. One person should observe the condition of the wheels and wheel chocks while the other is performing the test. Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3. Run the vehicle until the transmission fluid temperature has reached 50 to 80°C (122 to 176°F). Allow the engine to idle with the air conditioning OFF. Chock all 4 wheels. Set the parking brake and keep the brake pedal depressed firmly with your left foot. Move the shift lever to the D position. Depress the accelerator pedal as much as possible with your right foot. Read the engine rpm (stall speed) and release the accelerator pedal immediately. Standard value: 2,030 to 2,330 rpm Evaluation: EVALUATION Test Result Possible Cause Stall speed is lower than standard value Engine power output may be insufficient Stator one-way clutch not operating properly HINT: If the value is less than the specified value by 600 rpm or more, the torque converter could be faulty. Stall speed is higher than standard value Line pressure is too low Forward clutch slipping U/D (underdrive) brake slipping U/D (underdrive) one-way clutch is not operating properly No. 1 one-way clutch not operating properly Improper fluid level NOTE: Perform the test at the normal operating ATF temperature of 50 to 80°C (122 to 176°F).
2. SHIFT TIME LAG TEST HINT: This test is to check the condition of the direct clutch, forward clutch, 1st brake and reverse brake. Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3. Run the vehicle until the transmission fluid temperature has reached 50 to 80°C (122 to 176°F). Allow the engine to idle with the air conditioning OFF. Set the parking brake and keep the brake pedal depressed firmly. Check the D range time lag. Move the shift lever to N and wait for 1 minute. Move the shift lever to D and measure the time until the shock is felt. Repeat the 2 procedures above 3 times, and calculate the average time of the 3 tests. Check the R range time lag. Move the shift lever to N and wait for 1 minute. Move the shift lever to R and measure the time until the shock is felt. Repeat the 2 procedures above 3 times, and calculate the average time of the 3 tests. Standard value: D range time lag is less than 1.2 seconds R range time lag is less than 1.5 seconds Evaluation: EVALUATION Test Result Possible Cause D range time lag exceeds standard value Line pressure is too low Forward clutch worn No. 1 one-way clutch is not operating properly U/D (underdrive) one-way clutch is not operating U/D (underdrive) brake worn R range time lag exceeds standard value Line pressure is too low Reverse clutch worn 1st and reverse brake worn U/D (underdrive) brake worn

1. PERFORM HYDRAULIC TEST Measure the line pressure. NOTE: Perform the test at the normal operating ATF temperature: 50 to 80°C (122 to 176°F). The line pressure test should always be performed with at least 2 people. One person should observe the condition of the wheels or wheel chocks while the other is performing the test. Be careful to prevent SST's hose from interfering with the exhaust pipe. This test must be performed after checking and adjusting the engine. Perform the test with the A/C OFF. When conducting the stall test, do not continue for more than 10 seconds. Warm up the ATF (Automatic Transmission Fluid). Lift the vehicle up. Remove the engine under cover. Connect the intelligent tester to the DLC3. Remove the test plug A on the transaxle case front left side and install SST. SST 09992-00095 (09992-00231, 09992-00271) NOTE: There is a difference between the installation point of the D position and R position. Start the engine. Using intelligent tester, shift to D position and hold 3rd gear by active test, and measure the line pressure in idling. Specified line pressure: SPECIFIED LINE PRESSURE Condition D position kPa (kgf/cm 2 , psi) Idling 372 to 412 kPa (3.8 to 4.2 kgf/cm 2 , 54 to 60 psi) Turn the ignition switch off. Disconnect the connector of the transmission wire. HINT: Disconnect the connector only when performing the position stall test. Start the engine. Firmly depress the brake pedal, shift to the D position, depress the accelerator pedal all the way down and check the line pressure while the stall test is performed. Specified line pressure: SPECIFIED LINE PRESSURE Condition D position kPa (kgf/cm 2 , psi) Stall test 931 to 1,031 kPa (9.5 to 10.5 kgf/cm 2 , 135 to 150 psi) Turn the ignition switch off. Remove SST, and install the test plug A. Remove the test plug B, install SST and start the engine.

Scheme 1786

1. MANUAL SHIFTING TEST HINT: Through this test, it can be determined whether the trouble occurs in the electrical circuit or if it is a mechanical problem in the transaxle. If any abnormalities are found in the following test, the problem is in the transaxle itself. Disconnect the connector of the transmission wire. HINT: It is possible to deactivate the electrical shift control by disconnecting the transmission wire. The gear positions can then be changed mechanically with the shift lever. Drive with the transmission wire disconnected. Move the shift lever to each position to check whether the gear position changes as shown in the table below. SHIFT LEVER POSITION Shift Lever Position Shifting Condition L <--> 2 Not Shift (Not Change) 2 <--> 3 Down Shift <--> Up Shift 3 <--> 4 <--> D Not Shift (Not Change) HINT: While driving with the transmission wire disconnected: When the shift lever position is in L or 2, the gear position is held in 3rd. When the shift lever position is in 3, 4 or D, the gear position is held in 4th. When the shift lever position is in R or P, the operation is the same as usual. Connect the connector of the transmission wire. Clear the DTC (see «DTC CHECK / CLEAR»(ref-265069-S02065170702007092000000) ).

Scheme 1787

1. RESET MEMORY NOTE: Perform the RESET MEMORY procedures (A/T initialization) when replacing the automatic transaxle assembly, engine assembly or ECM. RESET MEMORY can be performed only with the intelligent tester. HINT: The ECM memorizes the vehicle conditions when the ECT controls the automatic transaxle assembly and engine assembly. Therefore, when the automatic transaxle assembly, engine assembly, or ECM has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information. The reset procedures are as follows. Turn the ignition switch OFF. Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3. Turn the ignition switch ON and turn the tester ON. Enter the following menus: DIAGNOSIS / ENHANCED OBD II. Perform the reset memory procedures from the Engine menu. CAUTION: After performing the RESET MEMORY procedures, be sure to perform the ROAD TEST (see «ROAD TEST»(ref-265069-S05431489102007092000000) ) as described earlier. HINT: The ECM learns through the ROAD TEST.

Scheme 1788

1. TEST MONITOR DRIVE PATTERN FOR ECT CAUTION: Perform this drive pattern on a level surface and strictly observe the posted speed limits and traffic laws while driving. HINT: Performing this drive pattern is one method to simulate the ECT's malfunction detection conditions. The DTCs may not be detected through ordinary, everyday driving. Also, DTCs may not be detected through this drive pattern. Preparation for driving Warm up the engine sufficiently (engine coolant temperature is 60°C (140°F) or higher). Drive the vehicle when the atmospheric temperature is -10°C (14°F) or higher. Malfunction is not detected when the atmospheric temperature is less than -10°C (14°F). Drive pattern Drive the vehicle through all the gears. Stop --> 1st --> 2nd --> 3rd --> 4th --> 5th --> 5th (lock-up ON). Repeat the above drive pattern 3 times or more. NOTE: When using the intelligent tester, the monitor status can be found in "ENHANCED OBD II / DATA LIST" or under "CARB OBD II". In the event that the drive pattern must be interrupted (due to traffic conditions or other factors), the drive pattern can be resumed and, in most cases, the monitor can be completed. CAUTION: Perform this drive pattern on a level road as much as possible and strictly observe the posted speed limits and traffic laws while driving. HINT: *: Drive at such a speed in the uppermost gear to engage lock-up. The vehicle can be driven at a speed lower than the speed shown in the above diagram under the lock-up condition. NOTE: It is necessary to drive the vehicle for approximately 30 minutes to detect DTC P0711 (Transmission fluid temperature sensor "A" performance).

FAIL-SAFE CHART

1. FAIL-SAFE CHART This function minimizes the loss of the ECT functions when a malfunction occurs in a sensor or solenoid. Automatic Transmission Fluid (ATF) temperature sensor: When the ATF temperature sensor has a malfunction, 5th up-shift is prohibited. Counter gear speed sensor NC (Speed sensor NC): When the counter gear speed sensor has a malfunction, 5th up-shift is prohibited. Shift solenoid valve DSL: When the solenoid valve DSL has a malfunction, the current to the solenoid valve is stopped. This stops lock-up control, then fuel economy decreases. Shift solenoid valve SL1, SL2, SL3 and S4: If any of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift solenoid "ON" and "OFF" in order to shift into the gear positions shown in the table below. Manual shifting as shown in the followin g table must be done. In case of a short circuit, the ECM stops sending the current to the short circuited solenoid. Even if starting the engine in the fail-safe mode, the gear position remains in the same position.
