- Engine and transmission must be at normal operating temperature. Place selector lever in "D" position. Accelerate vehicle gradually. Ensure all upshifts and downshifts occur at specified speeds. See SHIFT SPEED SPECIFICATIONS .
- Ensure TCC lock-up occurs at appropriate speeds. See LOCK-UP SPEED SPECIFICATIONS . Lightly depress accelerator pedal. If excessive increase in engine RPM is present, TCC lock-up will not occur.
- Check for shock and slippage at all upshifts. Check for abnormal noise and vibration. While driving in "D", "2" and "L" positions, ensure 2-1, 3-2 and 4-3 downshifts occur at specified speed. Check for shock and slippage at downshifts. If test results are not within specification, see "D" POSITION TEST RESULTS .
