17.) A high-mileage automatic transmission is being replaced. Tech cian, says that the oil cooler should be flushed. schnician B says that the line pressure should be increased. Who is right? A. A only B. B only C. Both A and B OD. Neither A nor B

## Step 1<br />This problem is about the maintenance of an automatic transmission in a vehicle. The two technicians, A and B, are suggesting different procedures for the maintenance of the transmission.<br /><br />## Step 2<br />Technician A suggests that the oil cooler should be flushed. This is a common practice in the maintenance of automatic transmissions. The oil cooler is a component that helps to regulate the temperature of the transmission fluid. Over time, the oil cooler can accumulate sludge and debris, which can affect the performance of the transmission. Therefore, flushing the oil cooler can help to remove these impurities and ensure the smooth operation of the transmission.<br /><br />## Step 3<br />Technician B suggests that the line pressure should be increased. This is not a standard procedure for the maintenance of an automatic transmission. The line pressure in an automatic transmission is regulated by the transmission control module (TCM), which is a computer that controls the transmission's operation. Increasing the line pressure can lead to premature wear of the transmission components and can also cause the transmission to slip.
