Adjusting the Adjustment Bolt
1. Locate the adjustment bolt. It is usually located either on the transmission housing or on the oil pan.

3. Using a socket wrench or socket with an extension, rotate the adjusting bolt 1/8 to 1/4 turns.
4. Rotate the wheel by hand to check if the noise or vibration is reduced.
5. Repeat steps 3-4 until the noise or vibration disappears.
Note:
* Caution: Avoid over-tightening the adjustment bolt as this may damage the belt or other components.
* It is recommended to check and adjust the automatic transmission brake band adjusting bolt every 50,000-60,000 km or when noise or vibration occurs.
*If you do not have experience with automatic transmissions, it is best to have a qualified mechanic perform this procedure.
