Stall Test
- Prepare for the mechanical system test. (See MECHANICAL SYSTEM TEST PREPARATION .)
- Firmly apply the parking brake and set the wheel blocks to the front and rear wheels.
- Start the engine.
- Measure the stall speed in the D position.
- Strongly depress the brake pedal with the left foot.
- Shift the selector lever to the D position.
- Slowly depress the accelerator pedal with the right foot all the way down.
- Read the engine speed quickly when the speed is stabilized, and remove the right foot from the accelerator pedal.
- Shift the selector lever to the N position and idle for 1 min or more.
- Measure the stall speed in each position in the same procedure.
- If there is any malfunction, one of the following malfunctions may have occurred:
Condition Possible cause Higher than specification High in R, D, and M (1GR, 2GR) positions Line pressure is low Oil pump wear ATF leakage from oil pump, control valve, and transaxle case Pressure regulator valve sticking Converter relief valve sticking Pressure control solenoid A operation malfunction Forward clutch slippage - One-way clutch No. 1 damage - 2-4 brake band slippage, and damage of one-way clutch No. 1 - Low and reverse brake slippage, and damage of one-way clutch No. 1 - Perform road test to determine whether problem is in reverse clutch or low and reverse brake - Engine brake operates in M (1GR) position
- Reverse clutch slippage
- Engine braking does not operate in M (1GR) position
- Low and reverse brake slippage
- Less than specification Lower in R, D, and M (1GR, 2GR) positions Engine malfunction One-way clutch damage in torque converter STALL SPEEDMeasurement conditions Specification (RPM) R position 2, 400-3, 000 D position M position
