D RANGE TEST IN NORM AND PWR PATTERN RANGES\n\nShift into the D range and hold the accelerator pedal constant at the full throttle valve opening position.\n\nCheck the following:\n\n(a) 1-2, 2-3 and 3.O/D up-shifts should take place, and shift points should conform to those shown in the automatic shift schedule.\n\nConduct a test under both Normal and Power patterns.\n\nHINT:\n• There is no O/D up-shift or lock-up when the coolant temp. is below 60°C (140°F) and speed is under 60 km/h (37 mph), or if there is a 10 km/h (6 mph) difference between the set cruise control speed.\n• There is no 3rd up-shift or lock-up when coolant temp. is below 35°C (95°F) and speed is under 40 km/h (25 mph).\n\nEVALUATION\n\n(1) If there is no 1 → 2 up-shift:\n• No. 2 solenoid is stuck\n• 1-2 shift valve

defective:\n• Throttle valve, 1-2 shift valve, 2-3 shift valve, 3-4 shift valve etc., are defective\n\n(5) If the lock-up is defective:\n• Lock-up solenoid is stuck\n• Lock-up relay valve is stuck\n\n(b) In the same manner, check the shock and slip at the 1 → 2, 2 → 3, and 3 → O/D up-shifts.\n\nEVALUATION\n\nIf the shock is excessive:\n• Line pressure is too high\n• Accumulator is defective\n• Check ball is
