Stall speed is lower than standard value | Stator one-way clutch is not operating properly Torque converter assembly is faulty (stall speed is less than standard value by 600 rpm or more) Engine power may be insufficient |
Stall speed is higher than standard value | Line pressure is low C1 clutch slipping F3 one-way clutch is not operating properly F4 one-way clutch is not operating properly |
- NOTICE:
