A73811 (c) Run at the D range lock-up or O/D gear and check for abnormal noise and vibration. HINT: The check for the cause of abnormal noise and vibration must be made with extreme care as it could also be due to loss of balance in the propeller shaft, differential, torque converter, etc. (d) While running in the D range, 2nd, 3rd and O/D gears, check to see that the possible kick-down vehicle speed limits for 2 → 1, 3 → 2 and O/D → 3 kick-downs conform to those indicated on the automatic shift schedule. (e) Check for abnormal shock and slip at kick-down. (f) Check for the lock-up mechanism. (1) Drive in D range, O/D gear, at a steady speed (lock-up ON) of about 75 km/h (47 mph). (2) Lightly depress the accelerator pedal and check that the engine rpm does not change abruptly. If there is a big jump in engine rpm, there is no lock-up. 2. 2 RANGE TEST Shift into 2 range and while driving with the accelerator pedal held constantly at the full throttle valve opening position, push in one of the pattern selectors and check on the following points. (a) Check to see that the 1 → 2 up-shift takes place and that the shift point conforms to it shown on the automatic shift schedule. HINT: • There is no O/D up-shift and lock-up in the 2 range. • To prevent overrun, the transmission up-shifts into 3rd gear at around 110 km/h (68 mph) [7M-GE] or 114 km/h (71 mph) [7M-GTE]. (b) While running in the 2 range and 2nd gear, release the accelerator pedal and check the engine braking effect. EVALUATION If there is no engine braking effect: • Second coast brake is defective
