Stall Speed Test

CAUTION: DO NOT maintain stall speed RPM for more than 5 seconds. Transaxle damage may occur.
  1. Operate engine and transaxle at normal operating temperature. Connect tachometer to vehicle and ensure it is visible to driver. Apply parking brake and block all 4 wheels.
  2. Ensure A/C is off. Start engine, apply brakes and place transaxle in "D" position. Depress accelerator to full throttle and note maximum RPM obtained. Repeat test in "R" position. For stall speed specifications, see STALL SPEED SPECIFICATIONS  table.
