JUDGEMENT OF STALL TEST
The test result and possible damaged components relating to each result are shown in the illustrations on next
page.
In order to pinpoint the possible damaged components, follow the WORK FLOW shown in
.
NOTE:
Stall revolution is too high in “D”, “2” or “1” position:
●
Slippage occurs in 1st gear but not in 2nd and 3rd gears. .. Low one-way clutch slippage
●
Slippage occurs in the following gears:
1st through 3rd gears in “D” position and engine brake functions with overdrive control switch set to
“OFF”.
1st and 2nd gears in “2” position and engine brake functions with accelerator pedal released (fully closed
throttle). .. Forward clutch or forward one-way clutch slippage
Stall revolution is too high in R position:
●
Engine brake does not function in “1” position. .. Low & reverse brake slippage
●
Engine brake functions in “1” position. .. Reverse clutch slippage
Stall revolution within specifications:
●
Vehicle does not achieve speed of more than 80 km/h (50 MPH). .. One-way clutch seizure in torque
converter housing
CAUTION:
Be careful since automatic fluid temperature increases abnormally.
●
Slippage occurs in 3rd and 4th gears in “D” position. .. High clutch slippage
●
Slippage occurs in 2nd and 4th gear in “D” position. .. Brake band slippage
●
Engine brake does not function in 2nd and 3rd gears in “D” position, 2nd gear in “2” position, and 1st gear
in “1” position with overdrive control switch set to “OFF”.
Stall revolution less than specifications:
●

LINE PRESSURE TEST PROCEDURE
1.
Check A/T fluid and engine oil levels. If necessary, add fluid or
oil.
2.

reach operating temperature.
3.
Install pressure gauge to corresponding line pressure port.
4.
Set parking brake and block wheels.
●
Continue to depress brake pedal fully while line pressure test is being performed at stall speed.
