Stall Speed Test
- Perform Mechanical System Test Preparation. (See Mechanical System Test Preparation ).
- Start the engine.
- Strongly depress the brake pedal with the left foot.
- Shift the selector lever to the D position.CAUTION:
- To prevent damage to the transmission, measure the line pressure while stalling (Step 5-6) within 5 s.
- Slowly depress the accelerator pedal fully 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 the M (1st gear) and R positions using the same procedure.
- If there is any malfunction, one of the following causes may have occurred:
Condition Possible cause Lower in R, D, and M (1GR) position - Engine lack of power
- Torque converter one-way clutch malfunction
Higher in D and M (1GR) position - Insufficient line pressure
- C1 clutch malfunction (slippage)
- F3 one-way clutch malfunction
Higher in R position - Insufficient line pressure
- B4 brake malfunction (slippage)
- C3 clutch malfunction (slippage)
- F1 one-way clutch malfunction
Higher in R, D, and M (1GR) position - Insufficient line pressure
- Oil leakage from each position circuit
