1. (6) Stop the engine.
2. 3. Measure the line pressure while stalling in D position. Replace the oil pressure gauge as following: When using the oil pressure gauge set (49 0378 400C) , replace the SST (49 B019 901B) with SST (49 B019 902A) . When using the oil pressure gauge set (49 D019 9A2) , replace the SST (49 D019 908) with SST (49 D019 907) . Connect the M-MDS to the DLC-2. Monitor the pressure control solenoid current (LPS) using the M-MDS data monitor function. Start the engine. Firmly depress the brake pedal with the left foot. Shift the selector lever to the D position. CAUTION: If the accelerator pedal is pressed for longer than 5 s while the brake pedal is pressed, the transaxle could be damaged. Therefore, perform Steps (7)-(8) within 5 s. Gradually depress the accelerator pedal with the right foot. When the engine speed no longer increases, quickly read the line pressure and release the accelerator pedal. Verify that the pressure control solenoid current changes as shown in the illustration depending on the throttle opening angle. NOTE: The line pressure standard other than when the engine is idling cannot be determined because the maximum line pressure for this transaxle is controlled by vehicle conditions. Shift the selector fever to the N position and idle the engine for 1 min or more to coot the ATF. Remove the SSTs. WARNING: Removing the SSTs when the ATF is hot can be dangerous. Hot ATF can come out of the opening and badly burn you. Before removing the SSTs, allow the ATF to cool. Install the test plug and new O-ring in the inspection port. Tightening torque 5.9-8.8 N.m {61-89 kgf.cm, 53-77 in.lbf} Stop the engine.
3. 4. Measure the line pressure while idling in R position. Remove the test plug (for the R position line) and the O-ring. Connect the SSTs as following: When using the oil pressure gauge set (49 0378 400C) , connect the SSTs (49 HD64 406A, 49 0378 400C, 49 B019 901B) to the line pressure inspection port as shown in the illustration. When using the oil pressure gauge set (49 D019 9A2) , connect the SSTs (49 D019 910,49 D019 911, 49 D019 912,49 D019 909, 49 D019 308) to the line pressure inspection port as shown in the illustration. Start the engine and warm it up until the ATF reaches 60-70 °C {140-158 °F}. Shift the selector lever to the R position. Read the line pressure while the engine is idling.

2. 6. Stop the engine. If there is any malfunction, inspect the following "Possible Cause" according to the condition. POSSIBLE CAUSE CONDITION REFERENCE CHART Condition Possible cause Lower than specification in R, D positions Line pressure control solenoid malfunction Primary regulator valve malfunction Oil pump malfunction Oil leaking from D position or R position hydraulic circuit Constant pressure without fluctuation in hydraulic pressure to throttle in R, D positions Line pressure control solenoid malfunction Control valve body internal malfunction Current to throttle does not change in R, D positions TCM internal malfunction Connector malfunction Hydraulic pressure in R position is not higher than D position Primary regulator valve malfunction

NOTE: Inspect with a tester that can indicate more than 10 megohms and confirm that the value is more than 1 megohm.
2. Measure the current white waving a magnet back and forth over the top of the input/turbine speed sensor (less than 5 mm {0.2 in}). If there is any malfunction, replace the input/turbine speed sensor.

4. Drain any ATF remaining in the torque converter.
5. Using a flathead screwdriver, position the drive gear on the oil pump component in the center.
6. Install the torque converter to the transaxle. CAUTION: Do not damage the oil seal. Do not drop the torque converter. Do not pinch fingers.
7. To ensure that the torque converter is installed accurately, measure distance A between the end of the torque converter and the end of the converter housing. Distance A (between the end of the torque converter and the end of the converter housing) 20 mm {0.79 in}
8. Install the transaxle. (See «AUTOMATIC TRANSAXLE REMOVAL/INSTALLATION [AY6A-EL]».)
9. Add ATF. (See «AUTOMATIC TRANSAXLE FLUID (ATF) LEVEL ADJUSTMENT [AY6A-EL]».)
10. Adjust the ATF level. (See «AUTOMATIC TRANSAXLE FLUID (ATF) LEVEL ADJUSTMENT [AY6A-EL]».)
11. Perform the "Mechanical System Test". (See «MECHANICAL SYSTEM TEST [AY6A-EL]».)
