6.) In an electronically shifted automatic transmission, the line pressure (EPC) is highest during: A. closed throttle B. steady cruise. C. cold operation OD. wide open throttle (WOT).

## Step 1<br />The line pressure (EPC) in an electronically shifted automatic transmission is the pressure that is applied to the transmission's internal components to facilitate gear changes. This pressure is crucial for the transmission's operation and is influenced by several factors.<br /><br />## Step 2<br />The line pressure is typically highest during wide open throttle (WOT). This is because, during WOT, the engine is delivering maximum power to the transmission. The transmission needs to handle this increased power, which requires a higher line pressure to ensure smooth and efficient gear changes.<br /><br />## Step 3<br />The other options, such as closed throttle, steady cruise, and cold operation, do not require the same level of line pressure as WOT. During these conditions, the engine is not delivering maximum power, and the transmission does not need to handle the same level of power as during WOT.
