The automatic transmission brake band adjusting bolt is located in the gearbox housing.
Its exact location may vary depending on the model and make of the car, but it is usually located:
* At the rear of the automatic transmission: Near the automatic transmission pan or the output shaft shank.
* On the side of the automatic transmission: Near the dipstick hole or in the gear selector area.
You can use a diagram or repair manuals for your specific vehicle model to find the adjusting bolt.
