TROUBLE DIAGNOSIS — BASIC INSPECTION
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 inAT-284, "
Work
Flow"(EXCEPT FOR EURO-OBD) orAT-61, "Work Flow"(EURO-OBD).
NOTE:
Stall revolution is too high in “D”, “2” or “1” position:
lSlippage occurs in 1st gear but not in 2nd and 3rd gears. ..... Low one-way clutch slippage
lSlippage 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:
lEngine brake does not function in “1” position. ..... Low & reverse brake slippage
lEngine brake functions in “1” position. ..... Reverse clutch slippage
Stall revolution within specifications:
lVehicle 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.
lSlippage occurs in 3rd and 4th gears in “D” position. ..... High clutch slippage
lSlippage occurs in 2nd and 4th gear in “D” position. ..... Brake band slippage
lEngine 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:
lPoor acceleration during starts. ..... One-way clutch seizure in torque converter
